Aminophylline Suppository 500mg Bronchodilators
COMPOSITION:
Each suppository contains Aminophykkine 500mg
PHARMACOLOGICAL ACTION :
Aminophylline is a soluble complex containing approximately 85% theophylline and 15% ethylenediamine. Aminophylline directly relaxes the smooth muscle of the bronchial airways and pulmonary blood vessels, thus acting mainly as a bronchodilator, pulmonary vasodilator and smooth muscle relaxant.
INDICATIONS:
AMINOPHYLLIN is indicated for relief of acute bronchial asthma and reversible bronchospasm associated with chronic bronchitis and emphysema, and in status asthmaticus; congestive heart failure; Cheyne-Stokes respiration; reduction of coughing, expectoration and exertional dyspnoea in emphysema patients, and for cardiac paroxysmal dyspnoea.
AMINOPHYLLIN SUPPOSICONES are intended for use in conditions requiring less urgent and more prolonged administration. AMINOPHYLLIN INJECTIONS are primarily for use in emergency situations.
CONTRA-INDICATIONS:
AMINOPHYLLIN should not be given to patients with active peptic ulcers, since it may increase the volume and acidity of gastric secretions. Patients with a history of hypersensitivity to aminophylline or theophylline should not be treated with AMINOPHYLLIN. Do not administer AMINOPHYLLIN with other xanthine preparations. Safe use of AMINOPHYLLIN in pregnancy has not been established.
DOSAGE AND DIRECTIONS FOR USE:
Supposicones:
Adults: One 500 mg supposicone once or twice daily.
Children: Use of the 500 mg supposicone is not recommended.
Supposicones must be removed from Rotoplast shells before use.
SIDE EFFECTS AND SPECIAL PRECAUTIONS:
Precautions:
Some children may be unusually sensitive to AMINOPHYLLIN.
Administration of ephedrine or other sympathomimetic drugs to patients already on treatment with AMINOPHYLLIN may result in toxic synergism.
Use with caution in patients with severe cardiac disease, hypertension, hyperthyroidism, acute myocardial injury, cor pulmonale, severe hypoxemia, hepatic impairment, or alcoholism, and in the elderly (especially males) and in neonates. Particular caution in dose administration must be exercised in patients with a history of peptic ulcer since the condition may be exacerbated. Caution should be used in giving aminophylline to patients in congestive heart failure. Serum levels in such patients may persist for long periods following discontinuation of the medicine. Theophylline half-life is shorter in smokers than non-smokers; therefore, smokers may require larger or more frequent doses.
Aminophylline may lower the seizure threshold.
Elevated serum levels of theophylline may occur in patients treated concomitantly with aminophylline and cimetidine, troleandomycin, erythromycin, allopurinol, or oral contraceptive steroids. Co-medication with phenobarbitone, phenytoin, or rifampicin may increase theophylline clearance and an increase of the aminophylline dose may be required. The excretion of lithium carbonate is increased in patients receiving aminophylline.
Consumption of coffee, tea, cola beverages, chocolate, or paracetamol contributes to falsely high serum theophylline levels when theophylline is measured spectrophotometrically without previous isolation by chromatography.
SIDE-EFFECTS:
The most consistent adverse reactions observed with therapeutic amounts of aminophylline are:
| 1. | Gastrointestinal: nausea, vomiting, anorexia, bitter aftertaste, dyspepsia, heavy feeling in the stomach, and gastrointestinal distress. |
| 2. | Central nervous system: dizziness, vertigo, light-headedness, headache, nervousness, insomnia, and agitation. |
| 3. | Cardiovascular: palpitation, tachycardia, flushing, extrasystoles and cardiac rhythm disturbances. |
| 4. | Respiratory: increase in respiratory rate. |
| 5. | Dermatologic: urticaria. |
Proctitis may follow the repeated administration of aminophylline suppositories. The benzocaine in the suppositories may cause local irritation.
STORAGE INSTRUCTIONS:
Store in a cool dry place (below 25°C) away from light.
Keep out of reach of children.
