Bulk Active Pharmaceutical Ingredient (API) Sources for OTIPRIO

Last updated: July 28, 2025

Introduction

OTIPRIO (ciprofloxacin otic suspension) is an FDA-approved antibiotic indicated for the treatment of acute otitis media with tympanostomy tubes in pediatric and adult populations. As a key component, ciprofloxacin hydrochloride—a potent fluoroquinolone antibiotic—is the active pharmaceutical ingredient (API) responsible for its efficacy. Securing a reliable, high-quality bulk API source is critical for pharmaceutical manufacturers aiming to produce OTIPRIO consistently and meet regulatory standards. This article provides an in-depth analysis of potential API suppliers for ciprofloxacin hydrochloride, evaluates sourcing strategies, and discusses implications for stakeholders.
