  • are allergic (hypersensitive) to meptazinol or any of the other ingredients of Meptid Tablets (see Section 6 ‘Further information’)


  • have any alcohol-related problems


  • have or you are at risk of getting paralysis of the gut (intestine) known as paralytic ileus


  • have a head injury, or build-up of pressure in the head (raised intracranial pressure)


  • are having problems breathing




Take special care with Meptid Tablets if you



  • have any liver or kidney problems


  • have any severe breathing problems such as asthma (do not take this medicine during an asthma attack)


  • have low blood pressure


  • have an under-active thyroid gland (hypothyroidism)


  • have an enlarged prostate gland


  • suffer from fits or seizures (convulsive disorder)


  • think your pain is due to a heart attack.

If any of these apply to you, tell your doctor or pharmacist before you take Meptid Tablets.





Taking other medicines



Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.



If you are taking any medicines known as monoamine-oxidase inhibitors (MAOIs) including moclobemide to treat, for example, depression, or if you have taken this type of medicine during the past two weeks, you should also talk to your doctor.



In particular, tell your doctor if you are taking, or have recently taken, any of the following medicines which are known to interact with Meptid Tablets:



  • medicines for treatment of depression known as monoamine-oxidase inhibitors (MAOIs) including moclobemide, and those called tricyclic antidepressants such as amitriptyline or mirtazapine


  • medicines for certain mental disorders, such as chlorpromazine


  • ritonavir (for HIV infection)


  • ciprofloxacin (for bacterial infections)


  • domperidone and metoclopramide (for nausea and vomiting)


  • cimetidine (for ulcers)


  • anti-anxiety and sleeping medicines such as diazepam and nitrazepam




Taking Meptid Tablets with food and drink



Avoid taking alcohol with this medicine as it may make you feel especially dizzy and sleepy.





Pregnancy and breast-feeding



Ask your doctor or pharmacist for advice before taking any medicine.



You should not take Meptid Tablets during pregnancy or while breast-feeding unless your doctor thinks that it is essential.





Driving and using machines



If this product makes you dizzy or drowsy, you should not drive or operate machinery.





Important information about some of the ingredients of Meptid Tablets



Meptid Tablets contain the colouring agent sunset yellow FCF (E110), which may cause allergic reactions in some people






How To Take Meptid Tablets



Always take Meptid Tablets exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.




The usual dose is



Adults and elderly patients:



Swallow one tablet, with a glass of water, every four hours; your doctor may vary the dose if necessary.



If you have the impression that the effect of Meptid Tablets is too strong or too weak, talk to your doctor or pharmacist.



Do not take more than your doctor has recommended.



Long term use of Meptid Tablets may cause dependence and tolerance. If you are worried about this, talk to your doctor or pharmacist. Meptid Tablets are usually only used for short-term treatment of pain.



Children:



Meptid Tablets are not recommended for use in children.





If you take more Meptid Tablets than you should



If you think you have taken too many tablets contact your doctor or the local hospital casualty department at once. Take any remaining tablets and the packaging with you.





If you forget to take Meptid Tablets



If you forget to take a dose at the right time, take it as soon as you remember, unless it is almost time for your next dose.



If you miss a dose completely, do not take a double dose to make up for the forgotten one. Instead, skip the missed one and take the next dose as usual.

Meningococcal group C conjugate vaccine


2. Qualitative And Quantitative Composition








One dose (0.5 ml of the reconstituted vaccine) contains:


 


Neisseria meningitidis group C (strain C11) oligosaccharide



Conjugated to



Corynebacterium diphtheriae CRM-197 protein



adsorbed on aluminium hydroxide




10 micrograms



 



12.5 to 25.0 micrograms



0.3 to 0.4 mg Al 3+



For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Powder and solvent for suspension for injection.



Powder (vial): white to off-white



Suspension (syringe): white opalescent



4. Clinical Particulars



4.1 Therapeutic Indications



Active immunisation of children from 2 months of age, adolescents and adults, for the prevention of invasive disease caused by Neisseria meningitidis group C.



The use of Menjugate Kit should be determined on the basis of official recommendations.



4.2 Posology And Method Of Administration



Posology



There are no data on the use of different Meningococcal group C conjugate vaccines within the primary series or for boosting. Whenever possible, the same vaccine should be used throughout.



Primary immunisation



Infants from 2 months of age up to 12 months: two doses, each of 0.5 ml, should be given with an interval of at least 2 months (See section 4.5 regarding co-administration of Menjugate Kit with other vaccines).



Children over the age of 12 months, adolescents and adults: a single dose of 0.5 ml.



Booster doses



It is recommended that a booster dose should be given after completion of the primary immunisation series in infants. The timing of this dose should be in accordance with available official recommendations. Information on responses to booster doses and on co-administration with other childhood vaccines is given in sections 5.1 and 4.5, respectively.



The need for booster doses in subjects primed with a single dose (i.e. aged 12 months or more when first immunised) has not yet been established (see section 5.1).



Method of Administration



Intramuscular injection. The vaccine (0.5 ml) is intended for deep intramuscular injection, preferably in the anterolateral thigh in infants and in the deltoid region in older children, adolescents and adults.



The vaccine must not be injected intravenously, subcutaneously or intradermally.



Menjugate Kit must not be mixed with other vaccines in the same syringe. Separate injection sites must be used if more than one vaccine is being administered.



4.3 Contraindications



Hypersensitivity to the active substance(s) or to any of the excipients of the vaccine, including diphtheria toxoid.



Persons who have shown signs of hypersensitivity after previous administration of Menjugate Kit.



As with other vaccines, administration of Menjugate Kit must be postponed in subjects with an acute severe febrile illness.



4.4 Special Warnings And Precautions For Use



Before the injection of any vaccine, the person responsible for administration must take all precautions known for the prevention of allergic or any other reactions. As with all injectable vaccines, appropriate medical treatment and supervision must always be readily available in case of a rare anaphylactic event following administration of the vaccine.



Prior to administration of any dose of Menjugate Kit, the parent or guardian must be asked about the personal history, family history, and recent health status of the vaccine recipient, including immunisation history, current health status and any adverse event after previous immunisations.



The benefits of vaccination with meningococcal group C conjugate vaccine must be reviewed in light of the incidence of N. meningitidis group C infection in a given population before the institution of a widespread immunisation campaign.



Menjugate Kit will not protect against meningococcal diseases caused by any of the other types of meningococcal bacteria (A, B, 29-E, H, I, K, L, W-135, X, Y, or Z, including non-typed). Complete protection against meningococcal group C infection cannot be guaranteed.



No data on the applicability of the vaccine for post-exposure outbreak control are as yet available.



In individuals deficient in producing antibodies, vaccination may not result in an appropriate protective antibody response. While HIV infection is not a contraindication, Menjugate Kit has not been specifically evaluated in the immunocompromised. Individuals with complement deficiencies and individuals with functional or anatomical asplenia may mount an immune response to meningococcal group C conjugate vaccines; however, the degree of protection that would be afforded is unknown.



Although symptoms of meningism such as neck pain/stiffness or photophobia have been reported there is no evidence that the vaccine causes meningococcal C meningitis. Clinical alertness to the possibility of co-incidental meningitis must therefore be maintained.



Conjugate vaccines containing Cross Reacting Material 197 (CRM197) should not be considered as immunising agents against diphtheria. No changes in the schedule for administering vaccines containing Diphtheria Toxoid are recommended.



Any acute infection or febrile illness is reason for delaying the use of Menjugate Kit except when, in the opinion of the physician, withholding the vaccine entails a greater risk. A minor afebrile illness, such as a mild upper respiratory infection, is not usually reason to defer immunisation.



The potential risk of apnoea and the need for respiratory monitoring for 48-72 hours should be considered when administering the primary immunisation series to very premature infants (born



The vaccine must not be injected intravenously, subcutaneously or intradermally.



Menjugate Kit has not been evaluated in persons with thrombocytopenia or bleeding disorders. The risk versus benefit for persons at risk of haemorrhage following intramuscular injection must be evaluated.



Parents must be informed of the immunisation schedule for this vaccine. Precautions such as useful antipyretic measures for this vaccine must be relayed to the parent or guardian and the need to report any adverse event must be stressed.



The tip cap of the syringe contains 10% Dry Natural Rubber. Although the risk for developing allergic latex reactions is very small, healthcare professionals are encouraged to consider the benefit risk prior to administering this vaccine to patients with know history of hypersensitivity to latex.



There are no data in adults aged 65 years and older (see section 5.1).



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Menjugate Kit must not be mixed with other vaccines in the same syringe. Separate injection sites must be used if more than one vaccine is being administered.



Administration of Menjugate Kit at the same time as (but, for injected vaccines, at a different injection site) the following vaccines in clinical studies did not reduce the immunological response to any of these other antigens:



- Polio (inactivated polio vaccine [IPV] and oral polio vaccine);



- Diphtheria [D] and Tetanus [T] toxoids alone or in combination with whole cell or acellular Pertussis [aP];



- Haemophilus Influenzae type B [Hib] conjugate vaccine;



- Hepatitis B [HBV] vaccine administered alone or at the same time as combined vaccine containing D, T, Hib, IPV and aP;



- Combined measles, mumps and rubella vaccine;



- 7-valent pneumococcal conjugate vaccine (Prevenar). The effect of concomitant administration of Menjugate with 7-valent pneumococcal conjugate vaccine (Prevenar) and a hexavalent vaccine [DTaP-HBV-IPV-Hib] on immune responses was assessed in infants vaccinated at median ages of approximately 2, 4.5 and 6.5 months. The potential for immune interference has not been assessed at other primary immunisation schedules.



Minor variations in GMT antibody titres were observed between studies; however, the clinical significance, if any, of these observations is not established.



In various studies with different vaccines, concomitant administration of meningococcal group C conjugates with combinations containing aP components (with or without IPV, hepatitis B surface antigen or Hib conjugates) has been shown to result in lower SBA GMTs compared to separate administrations or to co-administration with whole cell pertussis vaccines. The proportions reaching SBA titres of at least 1:8 or 1:128 are not affected. At present, the potential implications of these observations for the duration of protection are not known.



4.6 Pregnancy And Lactation



Pregnancy



There are no data on the use of this vaccine in pregnant women. Animal studies in rabbit at different stages of gestation have not demonstrated a risk to the foetus following administration of Menjugate Kit. Nevertheless, considering the severity of meningococcal group C disease pregnancy should not preclude vaccination when the risk of exposure is clearly defined.



Lactation



Information on the safety of the vaccine during lactation is not available. The benefit-risk ratio must be examined before making the decision as to whether to immunise during lactation.



4.7 Effects On Ability To Drive And Use Machines



No studies on the effects on the ability to drive and use machines have been performed.



Dizziness has been very rarely reported following vaccination. This may temporarily affect the ability to drive or use machines.



4.8 Undesirable Effects



The following descriptions of frequency have been defined: Very common (



Adverse Reactions from clinical trials



Adverse reactions reported across all age groups are provided below. Adverse reactions were collected on the day of vaccination and each day following for at least 3 and up to 6 days. The majority of reactions were self-limiting and resolved within the follow-up period.



In all age groups injection site reactions (including redness, swelling and tenderness/pain) were very common (ranging from 1 in 3 older children to 1 in 10 pre-school children). However, these were not usually clinically significant. Redness or swelling of at least 3cm and tenderness interfering with movement for more than 48 hours was infrequent where studied.



Fever of at least 38.0°C is common (ranging from 1 in 20 in infants and toddlers to 1 in 10 in pre-school children), but does not usually exceed 39.1°C, particularly in older age groups.



In infants and toddlers symptoms including crying and vomiting (toddlers) were common after vaccination. Irritability, drowsiness, impaired sleeping, anorexia, diarrhoea and vomiting (infants) were very common after vaccination. There was no evidence that these were related to Menjugate Kit rather than concomitant vaccines, particularly DTP.



Very commonly reported adverse events include myalgia and arthralgia in adults. Drowsiness was commonly reported in younger children. Headache was very common in secondary school children and common in primary school children.

Adverse Reactions from Post Marketing Surveillance (for all age groups)



The most commonly reported suspected reactions in post marketing surveillance include dizziness, pyrexia, headache, nausea, vomiting and faints.



The frequencies given below are based on spontaneous reporting rates, for this and other Meningococcal group C conjugate vaccines and have been calculated using the number of reports received as the numerator and the total number of doses distributed as the denominator.








Nervous system disorders



 


Very rare




Dizziness, convulsions including febrile convulsions, faints, hypoaesthesia and paraesthesia, hypotonia



There have been very rare reports of seizures following Menjugate Kit vaccination; individuals have usually rapidly recovered. Some of the reported seizures may have been faints. The reporting rate of seizures was below the background rate of epilepsy in children. In infants seizures were usually associated with fever and were likely to be febrile convulsions.



There have been very rare reports of visual disturbances and photophobia following vaccination with Meningococcal group C conjugate vaccines, usually in conjunction with other neurological symptoms like headache and dizziness.






Respiratory, thoracic and mediastinal disorders




Apnoea in very premature infants (

Lymphadenopathy, anaphylaxis, hypersensitivity reactions including bronchospasm, facial oedema and angioedema.



Relapse of nephrotic syndrome has been reported in association with Meningococcal group C conjugate vaccines.



4.9 Overdose



No case of overdose has been reported. Since each injection is a single dose of 0.5 millilitres, overdose is unlikely.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Meningococcal vaccines, ATC code: J07A H.



Immunogenicity



No prospective efficacy trials have been performed.



The serum bactericidal assay (BCA) referenced in the text below used human serum as a source of complement. Serum bactericidal assay (BCA) results achieved with human serum as a source of complement are not directly comparable with those achieved with rabbit serum as a source of complement.



Data on the use of a 2-dose primary immunisation series are available from a clinical trial that compared a 2, 3, 4 month vaccination schedule to a 2, 4 month vaccination schedule in 241 infants. One month after completion of the primary series nearly all subjects had attained hBCA titres



Compared to licensed unconjugated meningococcal polysaccharide vaccines in clinical studies, the immune response induced by Menjugate Kit was shown to be superior in toddlers, children and adolescents, and was comparable in adults (see table). Additionally, unlike unconjugated polysaccharide vaccines, Menjugate Kit induces immunologic memory after vaccination, although the duration of protection is not yet established.



There are no data in adults aged 65 years or older.

Post-marketing surveillance following an immunisation campaign in the UK



Estimates of vaccine effectiveness from the UK's routine immunisation programme (using various quantities of three meningococcal group C conjugate vaccines) covering the period from introduction at the end of 1999 to March 2004 demonstrated the need for a booster dose after completion of the primary series (three doses administered at 2, 3 and 4 months). Within one year of completion of the primary series, vaccine effectiveness in the infant cohort was estimated at 93% (95% confidence intervals 67, 99). However, more than one year after completion of the primary series, there was clear evidence of waning protection.



Up to 2007 the overall estimates of effectiveness in age cohorts from 1-18 years that received a single dose of meningococcal group C conjugate vaccine during the initial catch-up vaccination programme in the UK fall between 83 and 100%. The data show no significant fall in effectiveness within these age cohorts when comparing time periods less than a year or one year or more since immunisation.



5.2 Pharmacokinetic Properties



No pharmacokinetic studies have been conducted with Menjugate Kit, in accordance with its status as a vaccine.



5.3 Preclinical Safety Data



Non-clinical data reveal no special hazard for humans based on conventional studies of repeated dose toxicity and toxicity to reproduction (embryofetal studies).

Maxolon Tablets 10mg





1. Name Of The Medicinal Product



Maxolon® Tablets 10mg


2. Qualitative And Quantitative Composition



Each tablet contains Metoclopramide Hydrochloride BP equivalent to 10mg of the anhydrous substance.



3. Pharmaceutical Form



White uncoated tablets scored and engraved 'Maxolon'.



4. Clinical Particulars



4.1 Therapeutic Indications



Adults (20 years and over)



Digestive disorders:



'Maxolon' restores normal co-ordination and tone to the upper digestive tract.



'Maxolon' relieves the symptoms of gastro-duodenal dysfunction including:










Dyspepsia,




Heartburn,




Flatulence,




Sickness,




Regurgitation of bile,




Pain



These symptoms may be associated with such conditions as:










Peptic ulcer,




Duodenitis,




Reflux oesophagitis,




Hiatus hernia,




Gastritis,




Cholelithiasis and Post-cholecystectomy dyspepsia



Nausea and vomiting:



'Maxolon' is indicated for the treatment of the nausea and vomiting associated with:



Gastro-intestinal disorders,



Cyclical vomiting,



Intolerance to cytotoxic drugs,



Congestive heart failure,



Deep x-ray or cobalt therapy,



Post-anaesthetic vomiting



Migraine:



'Maxolon' relieves symptoms of nausea and vomiting, and overcomes gastric stasis associated with attacks of migraine. This improvement in gastric emptying assists the absorption of concurrently administered oral anti-migraine therapy (e.g. paracetamol) which may otherwise be impaired in such patients.



Post-operative conditions:



Post-operative gastric hypotonia



Post-vagotomy syndrome



'Maxolon' promotes normal gastric emptying and restores motility in vagotomised patients, and where post-operative symptoms suggest gastro-duodenal dysfunction.



Diagnostic procedures:



Radiology,



Duodenal intubation



'Maxolon' speeds up the passage of a barium meal by decreasing gastric emptying time, co-ordinating peristalsis and dilating the duodenal bulb. 'Maxolon' also facilitates duodenal intubation procedures.



Young adults and children



The use of 'Maxolon' in patients under 20 years should be restricted to the following:



Severe intractable vomiting of known cause, vomiting associated with radiotherapy and intolerance to cytotoxic drugs, as an aid to gastro-intestinal intubation, and as part of the premedication before surgical procedures



4.2 Posology And Method Of Administration



Route of administration:



Oral



The dosage recommendations given below should be strictly adhered to if side effects of the dystonic type are to be avoided. It should be noted that total daily dosage of 'Maxolon', especially for children and young adults, should not normally exceed 0.5mg/kg body weight.



In patients with clinically significant degrees of renal or hepatic impairment, therapy should be at reduced dosage. Metoclopramide is metabolised in the liver and the predominant route of elimination of metoclopramide and its metabolites is via the kidney.



Medical indications:



Adults 20 years and over:



10mg three times daily.



For patients of less than 60kg see below.



Elderly patients:



As for adults. To avoid adverse reactions adhere strictly to dosage recommendations and where prolonged therapy is considered necessary, patients should be regularly reviewed.



Young adults and children:



'Maxolon' should only be used after careful examination to avoid masking an underlying disorder, e.g. cerebral irritation. In the treatment of this group attention should be given primarily to body weight and treatment should commence at the lower dosage where stated.









Young adults:

15-19 years 60kg and over

10mg three times daily

 

30-59kg

5mg three times daily


Tablets should not be used in children under the age of 15. A liquid presentation should be used in the younger age groups; more accurate dosage is facilitated by the use of the Paediatric Liquid.



Diagnostic indications:



A single dose of 'Maxolon' may be given 5-10 minutes before the examination, subject to body weight consideration, (see above), the following dosages are recommended.









Adults:

20 years and over

10-20mg

Young adults:

15-19 years

10mg


A liquid presentation should be used in the younger age groups; more accurate dosage is facilitated by the use of the Paediatric liquid.



4.3 Contraindications



'Maxolon' should not be used in patients with phaeochromocytoma as it may induce an acute hypertensive response.



'Maxolon' should not be used during the first three to four days following operations such as pyloroplasty or gut anastomosis as vigorous muscular contractions may not help healing.



'Maxolon' should not be administered to patients with gastrointestinal obstruction, perforation or haemorrhage.



'Maxolon' is contra-indicated in patients who have previously shown hypersensitivity to metoclopramide or any of its components.



4.4 Special Warnings And Precautions For Use



Precautions:



If vomiting persists the patient should be reassessed to exclude the possibility of an underlying disorder e.g. cerebral irritation.



Care should be exercised in epileptic patients and patients being treated with other centrally acting drugs.



Since extrapyramidal symptoms may occur with both metoclopramide and neuroleptics such as the phenothiazines, particular care should be exercised in the event of these drugs being prescribed concurrently.



The neuroleptic malignant syndrome has been reported with metoclopramide in combination with neuroleptics as well as with metoclopramide monotherapy (see section 4.8 Undesirable effects).



Maxolon should be used with care in combination with other serotonergic drugs including SSRIs.



Special care should be taken in cases of severe renal and hepatic insufficiency (see also section 4.2 Posology and method of administration).



Care should be exercised when using Maxolon in patients with a history of atopy (including asthma) or porphyria.

The action of 'Maxolon' on the gastro-intestinal tract is antagonised by anticholinergics and opioid analgesics. The absorption of any concurrently administered oral medication may be modified by the effect of 'Maxolon' on gastric motility. Drugs known to be affected in this way include aspirin and paracetamol.



Since extrapyramidal reactions may occur with 'Maxolon', Phenothiazines and Tetrabenazine, care should be exercised in the event of co-administration of these drugs.



'Maxolon' should be used with care in association with other drugs acting at central dopamine receptors, such as levodopa, bromocriptine and pergolide.



The use of Maxolon with serotonergic drugs may increase the risk of serotonin syndrome.



'Maxolon' may reduce plasma concentrations of atovaquone.



4.6 Pregnancy And Lactation



Animal tests in several mammalian species and clinical experience have not indicated a teratogenic effect. Nevertheless 'Maxolon' should only be used when there are compelling reasons and is not advised during the first trimester.



During lactation metoclopramide is found in breast milk, therefore it should not be used during lactation.



4.7 Effects On Ability To Drive And Use Machines



1'Maxolon' may cause drowsiness, dyskinesia and dystonias which could affect the vision and also interfere with the ability to drive and operate machinery.



1 PL 20072/0048-0007; 27/07/2009



4.8 Undesirable Effects



Various extrapyramidal reactions to 'Maxolon', usually of the dystonic type, have been reported. The incidence of dystonic reactions, particularly in children and young adults, is increased if daily dosages higher than 0.5mg per kg body weight are administered. Dystonic reactions include: spasm of the facial muscles, trismus, rhythmic protrusion of the tongue, a bulbar type of speech, spasm of extra-ocular muscles including oculogyric crises, unnatural positioning of the head and shoulders and opisthotonos. There may be a generalised increase in muscle tone. The majority of reactions occur within 36 hours of starting treatment and the effects usually disappear within 24 hours of withdrawal of the drug. Should treatment of a dystonic reaction be required an anticholinergic anti-Parkinsonian drug, or a benzodiazepine may be used.



Very rare occurrences of the neuroleptic malignant syndrome have been reported. This syndrome is potentially fatal and comprises hyperpyrexia, altered consciousness, muscle rigidity, autonomic instability and elevated levels of creatine phosphokinase (CPK) and must be treated urgently (recognised treatments include dantrolene and bromocriptine). Metoclopramide should be stopped immediately if this syndrome occurs.



Tardive dyskinesia has been reported during prolonged treatment in a small number of mainly elderly patients. Patients on prolonged treatment should be regularly reviewed.



Very rarely hypersensitivity, including anaphylaxis, has been reported.



Rarely, drowsiness, restlessness, confusion, anxiety and diarrhoea have been reported in patients receiving metoclopramide therapy. Depression has been reported extremely rarely.



Raised serum prolactin levels have been observed during metoclopramide therapy: this may result in galactorrhoea, irregular periods and gynaecomastia.



Extremely rarely cases of red cell disorders such as methaemoglobinaemia and sulphaemoglobinaemia have been reported, particularly at high doses of metoclopramide. If this occurs the drug should be withdrawn. Methaemoglobinaemia may be treated using methylene blue.



A small number of skin reactions such as rashes, urticaria, pruritus and oedema have also been reported.



4.9 Overdose



In cases of overdosage, acute dystonic reactions have occurred. Should treatment of a dystonic reaction be required, an anticholinergic anti-Parkinsonian drug or a benzodiazepine may be used.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



The action of metoclopramide is closely associated with parasympathetic nervous control of the upper gastro-intestinal tract, where it has the effect of encouraging normal peristaltic action. This provides for a fundamental approach to the control of those conditions where disturbed gastro-intestinal motility is a common underlying factor.



5.2 Pharmacokinetic Properties



Metoclopramide is metabolised in the liver and the predominant route of elimination of metoclopramide and its metabolites is via the kidney.



5.3 Preclinical Safety Data



No additional data available.

Note: preparation must be under appropriate aseptic conditions if the above extended storage periods are required. The high dose ampoule presentation is not suitable for multidose use.



Elderly patients:



As for adults. To avoid adverse reactions adhere strictly to dosage recommendations.



Young adults and children:



'Maxolon' should only be used after careful examination to avoid masking an underlying disorder, e.g. cerebral irritation. In the dosage of this patient group attention should be given primarily to body weight.



4.3 Contraindications



'Maxolon' should not be used in patients with phaeochromocytoma as it may induce an acute hypertensive response.



'Maxolon' should not be used during the first three to four days following operations such as pyloroplasty or gut anastomosis as vigorous muscular contractions may not help healing.



'Maxolon' should not be administered to patients with gastrointestinal obstruction, perforation or haemorrhage.



'Maxolon' is contra-indicated in patients who have previously shown hypersensitivity to metoclopramide or any of its components.



4.4 Special Warnings And Precautions For Use



Precautions:



If vomiting persists the patient should be reassessed to exclude the possibility of an underlying disorder e.g. cerebral irritation.



Care should be exercised in epileptic patients and patients being treated with other centrally acting drugs.



Since extrapyramidal symptoms may occur with both metoclopramide and neuroleptics such as the phenothiazines, particular care should be exercised in the event of these drugs being prescribed concurrently.



The neuroleptic malignant syndrome has been reported with metoclopramide in combination with neuroleptics as well as with metoclopramide monotherapy (see section 4.8 Undesirable effects).



Maxolon should be used with care in combination with other serotonergic drugs including SSRIs.



Special care should be taken in cases of severe renal and hepatic insufficiency (see also section 4.2 Posology and method of administration).



Care should be exercised when using Maxolon in patients with a history of atopy (including asthma) or porphyria.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



The action of 'Maxolon' on the gastro-intestinal tract is antagonised by anticholinergics and opioid analgesics. The absorption of any concurrently administered oral medication may be modified by the effect of 'Maxolon' on gastric motility. Drugs known to be affected in this way include aspirin and paracetamol.



Since extrapyramidal reactions may occur with 'Maxolon', Phenothiazines and Tetrabenazine, care should be exercised in the event of co-administration of these drugs.



'Maxolon' should be used with care in association with other drugs acting at central dopamine receptors, such as levodopa, bromocriptine and pergolide.



The use of Maxolon with serotonergic drugs may increase the risk of serotonin syndrome.



'Maxolon' may reduce plasma concentrations of atovaquone.



4.6 Pregnancy And Lactation



Animal tests in several mammalian species and clinical experience have not indicated a teratogenic effect. Nevertheless 'Maxolon' should only be used when there are compelling reasons and is not advised during the first trimester.



During lactation metoclopramide is found in breast milk, therefore it should not be used during lactation.



4.7 Effects On Ability To Drive And Use Machines



1'Maxolon' may cause drowsiness, dyskinesia and dystonias which could affect the vision and also interfere with the ability to drive and operate machinery.



1 PL 20072/0052-0007; 27/07/09



4.8 Undesirable Effects



When given at high dose in association with cancer chemotherapy, 'Maxolon' has been found to be well tolerated with few adverse events. Various extrapyramidal reactions to 'Maxolon', usually of the dystonic type, have been reported. Studies of 'Maxolon' given in doses up to 10mg/kg body weight/day by IV infusion report an incidence of extrapyramidal reactions of less than 10%. The incidence of such reactions may be increased in the younger patient. Reactions to 'Maxolon' have included spasm of the facial muscles, trismus, rhythmic protrusion of the tongue, a bulbar type of speech, spasm of extra-ocular muscles including oculogyric crises, unnatural positioning of the head and shoulders and opisthotonos. There may be a generalised increase in muscle tone. The majority of reactions occur within 36 hours of starting treatment and the effects usually disappear within 24 hours of withdrawal of the drug. Should treatment of a dystonic reaction be required an anticholinergic anti-Parkinsonian drug, or a benzodiazepine may be used.



Very rare occurrences of the neuroleptic malignant syndrome have been reported. This syndrome is potentially fatal and comprises hyperpyrexia, altered consciousness, muscle rigidity, autonomic instability and elevated levels of creatine phosphokinase (CPK) and must be treated urgently (recognised treatments include dantrolene and bromocriptine).



Metoclopramide should be stopped immediately if this syndrome occurs.



There have been very rare reports of abnormalities of cardiac conduction (such as bradycardia and heart block) in association with intravenous metoclopramide.



Very rarely hypersensitivity, including anaphylaxis, has been reported.



Mild drowsiness, confusion, anxiety and diarrhoea have been noted. Depression has been reported extremely rarely.



Raised serum prolactin levels have been observed during metoclopramide therapy: this may result in galactorrhoea, irregular periods and gynaecomastia.



Extremely rarely cases of red cell disorders such as methaemoglobinaemia and sulphaemoglobinaemia have been reported, particularly at high doses of metoclopramide. If this occurs the drug should be withdrawn. Methaemoglobinaemia may be treated using methylene blue.



A small number of skin reactions such as rashes, urticaria, pruritus and oedema have also been reported.



4.9 Overdose



In cases of overdosage, acute dystonic reactions have occurred. Very rarely AV block has been observed. Should treatment of a dystonic reaction be required, an anticholinergic anti-Parkinsonian drug or a benzodiazepine may be used.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Maxolon 'High Dose' is indicated for the treatment of nausea and vomiting associated with intolerance to cytotoxic drugs. It is specially formulated to ensure compatibility in solution with cisplatin.



Maxolon exerts a three-fold anti-emetic action: by inhibiting central dopamine receptors Maxolon raises the threshold of the chemoreceptor trigger zone, and reduces the reaction of the adjacent vomiting centre to centrally-acting emetics. Maxolon decreases the sensitivity of the visceral afferent nerves to the vomiting centre, reducing the effect of locally-acting emetics and irritant substances. In the upper gastro-intestinal tract Maxolon promotes normal gastric emptying and it may thus abolish gastric stasis which is part of the vomiting reflex.



Maxolon 'High Dose' is not intended for use in the wider range of indications for which Maxolon at standard dose is indicated.



5.2 Pharmacokinetic Properties



Based on current literature, a metoclopramide concentration range of about 0.85µg/ml would appear desirable for the control of cytotoxic drug induced emesis. Such plasma concentrations may be achieved by the administration of a loading dose of 2-4 mg/kg infused over 15-30 minutes prior to cytotoxic drug therapy followed by a maintenance continuous infusion of 3-5 mg/kg over 8-12 hours.



Metoclopramide is metabolised in the liver and the predominant route of elimination of metoclopramide and its metabolites is via the kidney. In patients with clinically significant degrees of renal or hepatic impairment, therapy should be at reduced dosage.



5.3 Preclinical Safety Data



No additional data available.

Megace 160 mg Tablets





1. Name Of The Medicinal Product



Megace 160 mg Tablets


2. Qualitative And Quantitative Composition



Each tablet contains Megestrol Acetate 160 mg.



Also contains 224.5 mg Lactose Monohydrate.



For a full list of excipients, see section 6.1.



3. Pharmaceutical Form



Tablets



Off-white, oval, biconvex tablets with a break line, engraved '160' on one face.



The break line is only to facilitate breaking for ease of swallowing and not to divide into equal doses.



4. Clinical Particulars



4.1 Therapeutic Indications



Megace is a progestational agent, indicated for the treatment of certain hormone dependent neoplasms, such as breast cancer.



4.2 Posology And Method Of Administration



Breast cancer:



160 mg/day taken once daily.



At least two months of continuous treatment is considered an adequate period for determining the efficacy of Megace.



Children:



Megace is not recommended for use in children.



Elderly:



No dosage adjustment is necessary.



4.3 Contraindications



Megace is contra-indicated in patients who have demonstrated hypersensitivity to the drug.



Megace Tablets have not been shown to be bioequivalent to Megace Oral Suspension and therefore should not be substituted for Megace Oral Suspension in the treatment of anorexia or weight loss secondary to AIDS.



4.4 Special Warnings And Precautions For Use



Precautions:



Megace should be used with caution in patients with a history of thrombophlebitis and in patients with severe impaired liver function.



Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



None stated.



4.6 Pregnancy And Lactation



Megace should not normally be administered to women who are pregnant or to mothers who are breast feeding.



Fertility and reproduction studies with high doses of megestrol acetate have shown a reversible feminising effect on some male rat foetuses.



Several reports suggest an association between intrauterine exposure to progestational drugs in the first trimester of pregnancy and genital abnormalities in male and female foetuses. The risk of hypospadias in male foetuses may be approximately doubled with the exposure to progestational drugs. There are insufficient data to quantify the risk to exposed female foetuses, however some of these drugs induce mild virilisation of the external genitalia of the female foetuses.



If a patient is exposed to Megace during the first four months of pregnancy or if she becomes pregnant whilst taking Megace, she should be apprised of the potential risks to the foetus.



Women of child bearing potential should be advised to avoid becoming pregnant.



Because of the potential for adverse effects, nursing should be discontinued during treatment with Megace.



4.7 Effects On Ability To Drive And Use Machines



None stated.



4.8 Undesirable Effects



The major side-effect experienced by patients while taking megestrol acetate, particularly at high doses, is weight gain, which is usually not associated with water retention, but which is secondary to an increased appetite and food intake. Other occasionally noted side effects are nausea, vomiting oedema and breakthrough uterine bleeding. Reports have been received of patients developing dyspnoea, heart failure, hypertension, hot flushes, mood changes, Cushingoid facies, tumour flare (with or without hypercalcaemia), hyperglycaemia, alopecia and carpal tunnel syndrome while taking megestrol acetate. Thromboembolic phenomena including thrombophlebitis and pulmonary embolism (in some cases fatal) have been reported. A rarely encountered side effect of prolonged administration of megestrol acetate is urticaria, presumably an idiosyncratic reaction to the drug. The drug is devoid of the myelosuppressive activity characteristic of many cytotoxic drugs and it causes no significant changes in haematology, blood chemistry or urinalysis.



Pituitary adrenal axis abnormalities including glucose intolerance, and Cushing's syndrome have been reported with the use of megestrol acetate. Clinically apparent adrenal insufficiency has been rarely reported in patients shortly after discontinuing megestrol acetate. The possibility of adrenal suppression should be considered in all patients taking or withdrawing from chronic megestrol acetate therapy. Replacement stress doses of glucocorticoids may be indicated.



4.9 Overdose



No serious side effects have resulted from studies involving Megace (megestrol acetate) administered in dosages as high as 1600 mg/day.



Reports of overdose have also been received in the postmarketing setting. Signs and symptoms reported in the context of overdose included diarrhoea, nausea, abdominal pain, shortness of breath, cough, unsteady gait, listlessness, and chest pain. There is no specific antidote for overdose with Megace. In case of overdose, appropriate supportive measures should be taken.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Megace (megestrol acetate) possesses pharmacologic properties similar to those of natural progesterone. Its progestational activity is slightly greater than that of medroxyprogesterone acetate, norethindrone, norethindrone acetate and norethynodrel; slightly less than that of chlormadinone acetate; and substantially less than that of norgestrel.



Megestrol acetate is a potent progestogen that exerts significant anti-oestrogenic effects. It has no androgenic or oestrogenic properties. It has anti-gonadotropic, anti-uterotropic and anti-androgenic/anti-myotropic actions. It has a slight but significant glucocorticoid effect and a very slight mineralocorticoid effect.



The progestational activity of megestrol acetate has been assessed in a number of standard tests, including Clauberg - McPhail, McGinty, uterotropic and carbonic anhydrase tests in rabbits; pregnancy maintenance and delay-of-implantation tests in rats; endometrial response in rhesus monkeys; conversion of an oestrogen-primed endometrium to a secretory one in normal women and in those with secondary amenorrhea with resultant withdrawal bleeding; induction of pseudopregnancy for treatment of endometriosis; and the delay-of-menses and thermogenic tests. In all these tests, progestational activity was high.



It has been demonstrated that megestrol acetate blocks oestrogen effects in the uteri of rats and mice in human cervical mucus and vaginal mucosa. Anti-gondotropic activity has been demonstrated in rats of both sexes.



5.2 Pharmacokinetic Properties



Animal



Peak plasma levels occur four to six hours after oral administration of radioactively labelled megestrol acetate to female rats. High concentrations are found in the liver, fat, adrenal glands, ovaries and kidneys. Radioactivity is almost wholly cleared within a week, chiefly by biliary excretion to the faeces.



In dogs, megestrol acetate metabolites are excreted primarily in the faeces. In rabbits, the principal route of metabolic excretion is urinary and the major metabolites are the 2-alpha-hydroxy-6-hydroxymethyl and 6-hydroxymethyl derivatives.



Human



Peak plasma levels of tritiated megestrol acetate and metabolites occur one to three hours after oral administration. When 4 to 91mg of c-labelled megestrol acetate were administered orally to women, the major route of drug elimination was in the urine. The urinary and fecal recovery of total radioactivity within 10 days ranged from 56.6% to 78.4% (mean 66.4%) and 7.7% to 30.3% (mean 19.8%), respectively. The total recovered radioactivity varied between 83.1% and 94.7% (mean 86.2%). Megestrol acetate metabolites, which were identified in the urine as glucuronide conjugates, were 17-alpha-acetoxy-2-alpha hydroxy-6-methylpregna-4, 6-diene-3, 20-dione; 17-alpha-acetoxy-6-hydroxymethylpregna-4, 6-diene-3, 20-dione; and 17-alpha-acetoxy-2 alpha-hydroxy-6-hydromethylpregna-4, 6-diene-3, 20-dione; these identified metabolites accounted for only 5-8% of the administered dose.



Serum concentrations were measured after the administration of single and multiple oral doses of megestrol acetate. Adult male and post-menopausal female volunteers, no more than 65 years of age participated in the study.



Megestrol acetate is readily absorbed following oral administration of 20, 40, 80 and 200 mg doses. Megestrol serum concentrations increase with increasing doses, the relationship between increasing dosage and increasing serum levels not being arithmetically proportional. Average peak serum concentrations for the four doses tested were 89, 190, 209 and 465 ng/ml.



Mean peak serum concentrations are found three hours after single-dose administration for all dosage levels studied. The serum concentration curve appears biphasic, and the beta-phase half-life is 15 to 20 hours long.



After multiple doses over a three-day period, serum levels increase each day and are estimated to reach 80% to 90% predicted steady-state levels on the third day.
