Praziquantel

Praziquantel is a well-established anthelmintic agent, first synthesized in the 1970s, with a pyrazinoisoquinoline core that disrupts calcium ion homeostasis in susceptible parasites. It remains the drug of choice for treating schistosomiasis and other trematode and cestode infections across both human and veterinary medicine. Our material is a high-purity crystalline powder (≥98% by HPLC), produced via a reliable synthetic route and rigorously controlled to meet pharmacopeial standards.

This API is supplied with comprehensive documentation to support formulation development and regulatory filings. It is suitable for oral solid dosage forms, including tablets and powders for suspension, as well as for veterinary feed additives and drinking water solutions. With a well-documented safety profile and decades of clinical use, praziquantel continues to be a cornerstone in global antiparasitic programs.
