Bulk Active Pharmaceutical Ingredient (API) Sources for XEPI

Last updated: July 27, 2025

Introduction

Xepi (oxazolidinone-class antibiotic) is a topical treatment primarily prescribed for impetigo. The active pharmaceutical ingredient (API) in Xepi is Rifamycin SV (Rif SO), a derivative of rifamycin. As with many antibiotics, the supply chain for its API, Rifamycin SV, is critical for manufacturing consistent, high-quality pharmaceutical products. Ensuring a robust, compliant API sourcing network is vital for manufacturers, regulatory bodies, and health stakeholders involved in Xepi production.

This analysis explores global API suppliers, their capabilities, compliance standards, and market dynamics pertinent to Rifamycin SV for Xepi. The focus is on sourcing strategies, quality assurance, and regulatory recognition to support uninterrupted manufacturing cycles.
