1. CHLORPHENAMINE TABLETS BP 4mg



2. Alpharma Chlorphenamine Hayfever & Allergy Relief Tablets



3. Vantage Chlorphenamine Hayfever & Allergy Relief Tablets



4. ALLERcalm Allergy Relief Tablets


2. Qualitative And Quantitative Composition



Each tablet contains 4mg Chlorphenamine Maleate.



3. Pharmaceutical Form



Yellow uncoated tablets.



4. Clinical Particulars



4.1 Therapeutic Indications



1) For the symptomatic control of all allergic conditions which are responsive to antihistamines, including hay fever, urticaria, vasomotor rhinitis, angioneurotic oedema, food allergy, drug and serum reactions, insect bites.



4.2 Posology And Method Of Administration



Posology



Adults: 1 tablet every four or six hours to a maximum daily dose of 24mg.



Not recommended for children under 12 years of age unless otherwise directed by a practitioner.



Elderly: As in adults, but the elderly are prone to confusional psychosis and other neurological anticholinergic effects.



Method of Administration



For oral administration.



4.3 Contraindications



Hypersensitivity to antihistamines; patients who have received therapy with MAOI's within the previous fourteen days.



4.4 Special Warnings And Precautions For Use



In common with other drugs having anticholinergic effects, Chlorphenamine should be used with caution in epilepsy, prostatic hypertrophy, glaucoma, hepatic disease, bronchitis, bronchiectasis, thyrotoxicosis, raised intra-ocular pressure, severe hypertension or cardiovascular disease and bronchial asthma.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Chlorphenamine may have an additive effect when used concurrently with hypnotics and anxiolytics causing potentiation of drowsiness. A similar additive effect will result from concurrent usage of alcohol with Chlorphenamine. MAOI therapy intensifies the anticholinergic effects of Chlorphenamine. Chlorphenamine inhibits phenytoin metabolism and can lead to phenytoin toxicity.



4.6 Pregnancy And Lactation



The safety of Chlorphenamine in pregnancy has not been established. Chlorphenamine should therefore only be used when clearly required and when potential benefits outweigh the potential unknown risks to the foetus. Use during the third trimester may result in reactions in the newborn or premature neonates.



Small amounts of antihistamines are excreted in breast milk. Use by nursing mothers is not recommended because of the risks of adverse effects in the infant.



Antihistamines may inhibit lactation.



4.7 Effects On Ability To Drive And Use Machines



The anticholinergic properties of Chlorphenamine may cause drowsiness, dizziness, blurred vision and psychomotor impairment, which can seriously hamper the patient's ability to drive and use machinery.



4.8 Undesirable Effects



Sedation varying from slight drowsiness to deep sleep. Inability to concentrate, lassitude, blurred vision, GI disturbances such as nausea, vomiting and diarrhoea may occasionally occur. Urinary retention, headaches, dryness of the mouth. Dizziness, palpitation, tachycardia, arrhythmias, hypotension, tightness of the chest, abdominal pain, dyspepsia, anorexia, hepatic including jaundice, thickening of the bronchial secretions, haemolytic anaemia and other blood dyscrasias infrequently occur.



Allergic reactions including exfoliative dermatitis, photosensitivity and skin reactions. Urticaria, twitching, muscular weakness and in co-ordination. Tinnitus, depression, irritability and nightmares infrequently occur.



Paradoxical excitation in children and confusional psychosis in the elderly can occur.



The effects of alcohol may be increased. Children and the elderly are more likely to experience the neurological anticholinergic effects.



4.9 Overdose



The estimated lethal dose of Chlorphenamine is 25-50mg/kg body weight.



Symptoms and signs include sedation, paradoxical stimulation of the CNS, toxic psychosis, seizures, apnoea, convulsions, anticholinergic effects, dystonic reactions and cardiovascular collapse including arrhythmias.



Treatment includes gastric lavage or emesis using ipecacuanha syrup. Following these measures activated charcoal and cathartics may be administered to minimise absorption. Other symptomatic and supportive measures should be provided with special attention to cardiac, respiratory, renal and hepatic functions and fluid and electrolyte balance.



Treat hypotension and arrhythmias vigorously. CNS convulsions may be treated with IV diazepam or phenytoin. Haemoperfusion may be used in severe cases.

Rythmodan 150mg Capsules.





1. Name Of The Medicinal Product



Rythmodan 150mg Capsules.


2. Qualitative And Quantitative Composition



Capsule containing Disopyramide 150mg.



For excipients, see 6.1.



3. Pharmaceutical Form



Capsule.



4. Clinical Particulars



4.1 Therapeutic Indications



Rythmodan is used in the treatment of cardiac arrhythmias as follows:-



1. The prevention and treatment of arrhythmias occurring after myocardial infarction.



2. Maintenance of normal rhythm following electroconversion eg atrial fibrillation, atrial flutter.



3. Persistent ventricular extrasystoles.



4. Control of arrhythmias following the use of digitalis or similar glycosides.



5. Suppression of arrhythmias during surgical procedures eg cardiac catheterisation.



6. The prevention of paraxysmal supraventricular tachycardia.



7. Other types of arrhythmias e.g. atrial extrasystoles, Wolff-Parkinson-White Syndrome.



4.2 Posology And Method Of Administration



Route of administration



Oral



300 mg to 800mg daily in divided doses.



Children :



Not recommended as insufficient data available.



Elderly



A dose reduction due to reduced renal and hepatic function in the elderly (especially elderly non-smokers) should be considered (see section 4.4)



4.3 Contraindications



Disopyramide is contra–indicated in un–paced second or third degree atrioventricular block; bundle–branch block associated with first–degree atrioventricular block ; unpaced bifasicular block; pre-existing long QT syndromes; severe sinus node dysfunction ; severe heart failure, unless of secondary to cardiac arrhythmia ; hypersensitivity to disopyramide. It is also contra–indicated in concomitant administration with other anti–arrhythmics or other drugs liable to provoke ventricular arrythmias, especially Torsade de Pointes (see section 4.5). The sustained release formulation is contra–indicated in patients with renal or hepatic impairment.



4.4 Special Warnings And Precautions For Use



Antiarrhythmic drugs belonging to the class 1c (Vaughan Williams Classification) were included in the Cardiac Arrhythmia Suppression Trial (CAST), a long term multicentre randomised, double blind study in patients with asymptomatic non life–threatening ventricular arrhythmia who have had a myocardial infarction more than six days but less than two years previously. A significant increase in mortality and non–fatal cardiac arrest rate was seen in patients treated with class 1c antiarrhythmic drugs when compared with a matched placebo group. The applicability of the CAST results to other antiarrhythmics and other populations (eg. those without recent infarction) is uncertain. At present, it is best to assume that the risk extends to other antiarrhythmic agents for patients with structural heart disease.



There is no evidence that prolonged suppression of ventricular premature contractions with antiarrhythmic drugs prevents sudden death. For this reason, antiarrhythmic drugs should not be prescribed for the treatment of patients with asymptomatic ventricular premature contractions.



All antiarrhythmic drugs can produce unwanted effects when they are used to treat symptomatic but not life threatening arrhythmia; the expected benefits should be balanced against their risks.



In patients with structural heart disease, proarrhythmia and cardiac decompensation are special risks associated with antiarrhythmic drugs. Special caution should be exercised when prescribing in this context.



Disopyramide should not be used in patients with uncompensated congestive heart failure, unless this heart failure is secondary to cardiac arrhythmia. If disopyramide is to be given under these circumstances, special care and monitoring are essential.



Life-threatening and haemodynamically significant arrhythmias are difficult to treat and affected patients have a high mortality risk. Treatment of these arrhythmias, by whatever modality, must be initiated in hospital.



Owing to its negative inotropic effect, disopyramide should be used with caution in patients suffering from significant cardiac failure.This group may be specially sensitive to the negative inotropic properties of disopyramide. Such patients should be fully digitalised or controlled with other therapy before treatment with disopyramide is commenced.



Aggravation of existing arrhythmia, or emergence of a new type of arrhythmia, demands urgent review of disopyramide treatment.



Similarly, if an atrioventricular block or a bifascicular block occurs during treatment, the use of disopyramide should be reviewed.



There have been reports of ventricular tachycardia, ventricular fibrillation and Torsade de Pointes in patients receiving disopyramide. These have usually, but not always, been associated with significant widening of the QRS complex or prolonged QT interval. The QT interval and QRS duration must be monitored and disopyramide should be stopped if these are increased by more than 25%. If these changes or arrhythmias develop the drug should be discontinued. Disopyramide should be used only with caution in patients with atrial flutter or atrial tachycardia with block as conversion of a partial AV block to a 1:1 response may occur, leading to a potentially more serious tachyarrhythmia.



The occurrence of hypotension following disopyramide administration requires prompt discontinuation of the drug. This has been observed especially in patients with cardiomyopathy or uncompensated congestive heart failure. Any resumption of therapy should be at a lower dose with close patient monitoring. Disopyramide should be used with caution in the treatment of digitalis intoxication.



Potassium imbalance: Antiarrhythmic drugs may be hazardous in patients with potassium imbalance, as potassium abnormalities can induce arrhythmias.



During treatment with disopyramide, potassium levels should be checked regularly. Patients treated with diuretics or stimulant laxatives are at particular risk of hypokalaemia.



Renal insufficiency: In renal insufficiency, the dosage of disopyramide should be reduced by adjusting the interval between administrations.



Hepatic insufficiency: Hepatic impairment causes an increase in the plasma half–life of Rythmodan and a reduced dosage may be required.



Hypoglycaemia:  Hypoglycaemia has been reported in association with disopyramide administration. The risk of hypoglycaemia, sometimes severe, occurs particularly in elderly or malnourished subjects, treated diabetics and patients with renal insufficiency or cardiac failure. Blood sugar levels should be monitored in all patients. Strict adherence to the dosing recommendations is advised. If hypoglycaemia occurs then treatment with disopyramide should be stopped.



Hypoglycaemia may be associated with interactions with drugs metabolised by hepatic CYP3A (see Section 4.5 Interactions with other medicinal products and other forms of interaction).



Atropine–like effects: There is a risk of :



– ocular hypertension in patients with narrow–angle glaucoma



– acute urinary retention in patients with prostatic enlargement



– aggravation of myasthenia gravis



– cognitive disorders, especially in elderly patients (see also section 4.8).



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Combination with other antiarrhythmic drugs: Combinations of antiarrhythmic drugs are not well researched and their effect may be unpredictable. Thus, antiarrhythmic combination should be avoided except under certain circumstances, eg. beta–blockers for angina pectoris ; digoxin with beta–blocker and verapamil for the control of atrial fibrillation, when defined as effective for an individual.



Interaction with drugs associated with risk of Torsade de Pointes, such as



– tricyclic and tetracyclic antidepressants



– All macrolide antibiotics (e.g. erythromycin, clarithromycin, azithromycin etc)



– astemizole ; cisapride ; pentamidine ; pimozide ; sparfloxacin ; terfenadine and thioridazone.



Phosphodiesterase Type 5 Inhibitors:



There is evidence that phosphodiesterase Type 5 inhibitors may be potentially associated with a risk of QT prolongation. Concomitant administration of disopyramide with such drugs may potentially enhance this QT prolongation effect and is not recommended.



The concomitant use of these medications whilst undergoing treatment with disopyramide increases the chance of cardiac arrhythmia.



There is some evidence that disopyramide is metabolised by hepatic CYP3A. Concomitant administration of significant inhibitors of this isozyme (e.g. certain macrolide or azole antifungal antibiotics) may therefore increase the serum levels of disopyramide. On the other hand, inducers of CYP3A (e.g. rifampicin and certain anticonvulsants such as phenytoin, primidone and phenobarbital) may reduce disopyramide and increase MN–disopyramide serum levels. Since the magnitude of such potential effects is not foreseeable, such drug combinations are not recommended.



When prescribing a drug metabolised by CYP3A [such as theophylline, HIV protease inhibitors (e.g. ritonavir, indinavir, saquinavir), ciclosporin A, warfarin] it should be kept in mind that disopyramide is probably also a substrate of this isozyme and thus competitive inhibition of metabolism might occur, possibly increasing serum levels of these drugs.



Interactions with hypokalaemia inducing drugs: Concomitant use with drugs can induce hypokalaemia such as : diuretics, amphotericin B, tetracosactide (corticotropin analogue), gluco and mineralo–corticoids may reduce the action of the drug, or potentiate proarrhythmic effects. Stimulant laxatives are not recommended to be given concomitantly, due to their potassium lowering potential.



Other drug interactions:



Atropine and other anticholinergic drugs, including phenothiazines, may potentiate the atropine–like effects of disopyramide.



4.6 Pregnancy And Lactation



Pregnancy: Although Rythmodan has undergone animal tests for teratogenicity without evidence of any effect on the developing foetus, its safety in human pregnancy has not been established. Rythmodan has been reported to stimulate contractions of the pregnant uterus. The drug should only be used during pregnancy if benefits clearly outweigh the possible risks to the mother and foetus.



Lactation: Studies have shown that oral Rythmodan is secreted in breast milk, although no adverse effects to the infant have been noted. However, clinical experience is limited and Rythmodan should only be used in lactation if, in the clinician's judgement, it is essential for the welfare of the patient. The infant should be closely supervised, particularly for anticholinergic effects and drug levels determined if necessary. Ideally, if the drug is considered essential, an alternative method of feeding should be used.



4.7 Effects On Ability To Drive And Use Machines



Some adverse reactions may impair the patients ability to concentrate and react, and hence the ability to drive or operate machinery. (See section 4.8).



4.8 Undesirable Effects



Cardiac: It is accepted that the arrhythmogenic potential of disopyramide is weak. However, as with all antiarrhythmic drugs, disopyramide may worsen or provoke arrhythmias. This proarrhythmic effect is more likely to occur in the presence of hypokalemia with the associated use of antiarrhythmic drugs, in patients with severe structural heart disease with prolongation of the QT interval.



Intra–cardiac conduction abnormalities may occur: QT interval prolongation, widening of the QRS complex, atrioventricular block and bundle–branch block.



Other types of arrhythmia have been reported: Bradycardia, sinus block, ventricular fibrillation, ventricular tachycardia and torsades de pointes.



Episodes of severe heart failure or even cardiogenic shock have also been described particularly in patients with severe structural heart disease. The resulting low cardiac output can cause hypotension, renal insufficiency and/or acute hepatic ischemia.



Other adverse reactions include:



Atropine-like effects (see also section 4.4):



urinary: dysuria; acute urinary retention, especially in prostatism



ocular: disorders of accommodation; diplopia



gastrointestinal: dry mouth; abdominal pain; nausea, vomiting, anorexia, diarrhoea; constipation



impotence



cognitive disorders



Psychiatric disorders.



Skin reactions: very rarely, rashes.



Rarely: hypoglycaemia, sometimes severe (see Section 4.4 Special warnings and precautions for use). In some cases, severe hypoglycaemia resulted in coma.



Very rarely: cholestatic jaundice, headache, dizzy sensation, neutropenia.



Rapid infusion may cause profuse sweating.



4.9 Overdose



There is no specific antidote for disopyramide. Prostigmine derivatives can be used to treat anticholinergic effects. Symptomatic supportive measures may include : early gastric lavage ; administration of a cathartic followed by activated charcoal by mouth or stomach tube ; IV administration of isoprenaline, other vasopressors and/or positive inotropic agents ; if needed - infusion of lactate and/or magnesium, electro–systolic assistance, cardioversion, insertion of an intra–aortic balloon for counterpulsion and mechanically assisted ventilation. Haemodialysis, haemofiltration or haemoperfusion with activated charcoal has been employed to lower the serum concentrations of the drug.
