Kinin ve Rifampisin etkileşimi

Quinine Prevention or Management : Avoid concomitant use Decrease AUC by 75%-85% Telithromycin Decrease AUC by 86% Theophylline Decrease exposure by 20%-40% Effect of Other Drugs on Rifampin Concomitant antacid administration may reduce the absorption of rifampin.

Avoid concomitant use with rifampin.

Concomitant Use of Rifampin Treatment failures may result from the concurrent use of rifampin with quinine sulfate, due to decreased plasma concentrations of quinine, and concomitant use of these medications should be avoided [see DRUG INTERACTIONS ( 7.1 )] .

Therefore the concomitant administration of rifampin with quinine sulfate should be avoided [see WARNINGS AND PRECAUTIONS ( 5.4 )] .

In healthy subjects (N=9) who received a single oral 600 mg dose of quinine sulfate after 2 weeks of pretreatment with rifampin 600 mg/day, the mean quinine AUC and C max decreased by 85% and 55%, respectively.

Antiepileptics (AEDs) (Carbamazepine, Phenobarbital, and Phenytoin) Carbamazepine, phenobarbital, and phenytoin are CYP3A4 inducers and may decrease quinine plasma concentrations if used concurrently with quinine sulfate.
