Description

Praziquantel CAS NO 55268-74-1 is a broad-spectrum anthelmintic compound belonging to the pyrazinoisoquinoline class. It is a critical active pharmaceutical ingredient (API) valued for its high efficacy and safety profile in treating parasitic worm infections. This product is essential for manufacturers in the pharmaceutical and veterinary medicine industries producing treatments for schistosomiasis and cestodiasis.

Application

• Human Pharmaceutical API: Primary active ingredient in tablets for the treatment of schistosomiasis (bilharzia) and infections caused by liver flukes and tapeworms.
• Veterinary Pharmaceutical API: Key component in formulations for deworming pets, livestock, and aquaculture species against a variety of cestode and trematode parasites.
• Research & Development: Used as a reference standard and in biochemical research to study helminth biology and anthelmintic mechanisms of action.
• Public Health Programs: Sourced for mass drug administration (MDA) initiatives in endemic regions to control and eliminate schistosomiasis.
• Formulation Development: Utilized in the development of new drug delivery systems, including pediatric formulations and combination therapies.
