Bulk Active Pharmaceutical Ingredient (API) Sources for: METRONIDAZOLE

Last updated: July 31, 2025

Introduction

Metronidazole, a nitroimidazole antibiotic and antiprotozoal agent, remains a cornerstone in treating anaerobic infections, protozoal diseases, and other bacterial conditions. Its global demand hinges significantly on the availability of high-quality bulk APIs from reliable manufacturers. This article explores the primary sources of bulk metronidazole API, assessing their manufacturing footprints, quality standards, regulatory compliance, and supply chain reliability.

Overview of Metronidazole API

Developed in the late 1950s, metronidazole is synthesized through complex chemical processes involving nitroimidazole core formation. The API must meet stringent pharmacopeial standards such as USP, EP, or JP to ensure safety and efficacy. The central manufacturing hubs for metronidazole are located predominantly in Asia, Europe, and North America, reflecting regional regulatory landscapes and market demands.
