title: Increased efficacy of liposomes-encapsulated praziquantel in treatment of opisthorchiasis in hamsters.
abstract: An increased efficacy of liposomes-encapsulated praziquantel was observed in the treatment of hamster opisthorchiasis. A single intracardial dose of 1.5 mg/kg of encapsulated praziquantel is as effective as an intracardial dose of 30 mg/kg or an oral dose of 100 mg/kg of free praziquantel. The suppressing activity of both free and liposomes-encapsulated praziquantel significantly decrease as the infection times increase from 1 to 5 weeks, suggesting that the young liver flukes are more susceptible to praziquantel than the adult flukes.
