Pharmacokinetics
Onset
- Initial Response
a) Fascioliasis, 2 to 9 days.
b) Resolution of fever has been reported 2 days after initiation of BITHIONOL therapy in fascioliasis, with eradication of ova in stools after 9 days.
c) Paragonimiasis, 3 to 5 days. (Significant improvement of hemoptysis in paragonimiasis has been reported after the third dose of oral BITHIONOL. Eradication of Paragonimus westermani ova has occurred after the fifth dose.)
Metabolism
- Metabolism Sites and Kinetics: Not extensively studied in humans. Animal studies suggest that BITHIONOL is metabolized in the liver, with metabolites being excreted in bile and urine.
