Description

Mebendazole CAS NO 31431-39-7 is a broad-spectrum anthelmintic agent belonging to the benzimidazole class. Its primary value lies in its potent efficacy against a wide range of parasitic worm infections by selectively inhibiting microtubule synthesis. This compound is a critical active pharmaceutical ingredient (API) essential for manufacturers in the human and veterinary pharmaceutical industries. It is formulated into various dosage forms to treat conditions such as ascariasis, trichuriasis, and hookworm infections.

Application

• Human Pharmaceutical Formulations: Primary API for the production of oral anthelmintic tablets, suspensions, and chewables.
• Veterinary Anthelmintics: Key ingredient in deworming pastes, pellets, and injectables for livestock, companion animals, and poultry.
• Public Health Programs: Used in mass drug administration initiatives to combat soil-transmitted helminthiasis in endemic regions.
• Research & Development: Serves as a reference standard and building block in pharmacological research for novel parasitic treatments.
• Generic Drug Manufacturing: Essential for companies producing bioequivalent versions of established anthelmintic medications.
