Pharmacology

Arofil SR 400 mg is a bronchodilator, structurally classified as a Methylxanthine. Arofil SR 400 mg has two distinct actions in the airways of patients with reversible obstruction; smooth muscle relaxation and suppression of the response of the airways to stimuli. Arofil SR 400 mg also increases the force of contraction of diaphragmatic muscles. The half-life of Arofil SR 400 mg is influenced by a number of known variables. In adult nonsmokers with uncomplicated asthma the half-life ranges from 3 to 9 hours

Dosage & Administration of Arofil SR 400 mg

The dose of Arofil SR 400 mg must be individualized on the basis of peak serum Arofil SR 400 mg concentration measurements in order to achieve a dose that will provide maximum potential benefit with minimal risk of adverse effects. Most of the sustained release preparations may be administered every 12 hours in adults while administration every 8 hours may be necessary in some children with markedly rapid hepaticmetabolism of Arofil SR 400 mg. The recommended maintenance dose within accepted therapeutic range is as follows : 16 years or older: 10 mg/Kg/day (Do not exceed 900 mg/day) 12 years-15 years: 13 mg/Kg/day 9-11 years: 16 mg/Kg/day 1 year-8 years: 24-24 mg/Kg/day 6 months-1 year: 12-18 mg/Kg/day 1-6 months: 10 mg/Kg/day.

Interaction of Arofil SR 400 mg

Arofil SR 400 mg should not be used concurrently with other preparations containing xanthine derivatives. The clearance of Arofil SR 400 mg is increased by barbiturates, carbamazepine, lithium, phenytoin, rifampicin and sulphinpyrazone and it may therefore be necessary to increase dosage. On the other hand, the clearance of the drug is reduced by allopurinol, cimetidine, ciprofloxacin, corticosteroids, erythromycin, frusemide, isoprenaline, oral contraceptive and thiabendazole and a reduced dosage may therefore be needed to avoid side effects. Arofil SR 400 mg can potentiate hypokalemia resulting from beta-2-agonist therapy, steroids, diuretics and hypoxia, so serum potassium levels should be monitored in such instances.

Contraindications

Arofil SR 400 mg is contraindicated in patients with hypersensitivity to Arofil SR 400 mg or any other component of the product.

Side Effects of Arofil SR 400 mg

Generally side effects are rare at normal dosage. It may include gastrointestinal discomfort, headache, nausea, insomnia and hypotension. CNS stimulation and diuresis may also occur, especially in children.

Pregnancy & Lactation

It is not known whether Arofil SR 400 mg can cause foetal harm when administered to pregnant woman. Xanthines should be given to a pregnant woman only if clearly needed. Arofil SR 400 mg is excreted into breast milk and may cause irritability or other signs of mild toxicity in nursing human infants. Serious adverse effects in the infant are unlikely unless the mother has toxic serum Arofil SR 400 mg concentrations.

Precautions & Warnings

Careful consideration is needed for various interacting drugs and physiologic conditions that can alter Arofil SR 400 mg clearance. Dosage adjustment is required prior to initiation of Arofil SR 400 mg therapy, prior to increases in Arofil SR 400 mg dose, and during follow up. The dose of Arofil SR 400 mg selected for initiation of therapy should be low and, if tolerated, increased slowly over a period of time.

Storage Conditions

Keep all medicines out of reach of children. Store in a cool and dry place, protected from light.

Use In Special Populations

Pediatrics use: The clearance of Arofil SR 400 mg is very low in neonates. Careful attention to dosage selection and monitoring of serum Arofil SR 400 mg concentrations are required in pediatric patients.
