STUDY ON THE PHARMACOKINETIC OF RIFAPENTINE IN VOLUNTEERS / 中国药理学通报

ABSTRACT

The pharmacokinetic study of Rifapentine by daily oral administration for 10d and followed by twice weekly for another 3 weeks in 9 volunteers and in comparism with Rifandin were reported. The results showed that the absorption and excretion of Rifapentine were markedly slower than that of Rifandin, its T1/2 was 15h. The Peak plasma level and T1/2 decreased after repeated administration of the drug. This suggested that Rifapentine and Rifandin in similar to Ri-fampin were hepatic microsomal enzyme inducers.
