Full text not available from this repository.Abstract
An article with illustrations.,The effects of phenobarbital (PB) and 3-methylcholanthrene (MC) pretreatment on the phannac~kinetics of praziquantel (PZQ), a schistosomicide were studied in Spnrgue-Dawley rats. Blood samples at different time intervals were obtained by severing the tail vein and were analyzed for unchanged PZQ by HPLC. The PB-pretreated rats showed a &fold decrtase in AUC, a 5-fold decrease in Cmax and an 8-fold increase in Ch compared to the saline treated controls. The MC-pretreated rats and their oliveoil treated controls did not show any statistically significant diffmnces in the above parameters. These results suggest that PZQ is extensively metabolised by PB-inducible cytochrome P-450 isoforms and not by MC-inducible isoforms. These findings also suggest that the bioavailability of praziquantel could be altered to a significant extent in humans taking drugs that are phenobarbital type inducers.,Research Board of the University of Zimbabwe and the International Programme in the Chemical Sciences, Sweden.
