“Drug-Drug Interaction Between Rifampin and Fluvastatin”
The effect of organic anion transporting polypeptide 1B1 (OATP1B1) transporter inhibition at clinical doses of fluvastatin, a biopharmaceutics drug disposition classification system (BDDCS) class 1 drug, has not been studied to date. A single dose of IV rifampin can be used as model OATP1B1 inhibitor to evaluate the significance of OATP1B1 transporter effects on fluvastatin disposition. A preinduction regimen of oral rifampin followed by a single IV infusion of rifampin can be used to evaluate the combined effects of enzyme induction and OATP1B1 transporter inhibition on fluvastatin disposition. A two arm, randomized, open label, crossover clinical study in healthy, volunteers will be conducted to evaluate the effects of IV rifampin on fluvastatin disposition in both hepatically induced and uninduced subjects.
Drug - Intravenous Rifampin
A 30-min intravenous infusion of rifampin 600mg in 10ml Normal Saline will be used to inhibit hepatic OATP1B1 transporters.
