Rifampicin fluvoxamine

Theophylline is a narrow therapeutic index drug with significant difference in bioavailability following oral administration. The half-life of the drug is increased by heart failure, cirrhosis and viral infections, in elderly patients, and by certain drugs, such as cimetidine, ciprofloxacin, oral contraceptives and fluvoxamine. The half-life is decreased in smokers, chronic alcoholism, and by certain drugs, such as phenytoin, rifampicin and carbamazepine. [Pg.249]

Interactions are similar to those of opioid analgesics. Methadone has interactions with enzyme inducers. Withdrawal symptoms of methadone are observed upon concurrent administration with phenobarbitone, phenytoin, and rifampicin. Methadone toxicity increases if administered with cimetidine and fluvoxamine. [Pg.342]
