Description

Erythromycinacistrate is a pharmaceutical-grade salt form of the macrolide antibiotic erythromycin, specifically designed for enhanced stability and formulation. This compound is critical for ensuring the efficacy and shelf-life of finished drug products, particularly in oral dosage forms. It is primarily required by manufacturers in the pharmaceutical and veterinary medicine industries for the production of reliable antibiotic formulations.

Application

• Pharmaceutical API: Used as an active pharmaceutical ingredient (API) in the manufacture of oral solid dosage forms such as tablets and capsules.
• Veterinary Medicine: Incorporated into medicated feeds and treatments for bacterial infections in livestock and companion animals.
• Drug Delivery Systems: Serves as a key component in controlled-release and taste-masked formulations to improve patient compliance.
• Intermediate for Synthesis: Acts as a chemical intermediate in the synthesis of more complex erythromycin derivatives and prodrugs.
• Research & Development: Utilized in preclinical and clinical research for developing new antibiotic therapies and studying pharmacokinetics.
