Bulk Active Pharmaceutical Ingredient (API) Sources for KERYDIN: An Industry Overview

Last updated: July 29, 2025

Introduction

KERYDIN (tavaborole) is an antifungal agent approved by the U.S. Food and Drug Administration (FDA) primarily for the topical treatment of onychomycosis, a fungal infection of the nails. As a synthetic boron-based compound, KERYDIN's production involves complex chemical synthesis, demanding reliable sources of high-quality Active Pharmaceutical Ingredients (APIs). This article provides an in-depth analysis of bulk API sources relevant to KERYDIN, highlighting key manufacturing regions, suppliers’ capabilities, regulatory considerations, and strategic sourcing insights for pharmaceutical companies.

Global API Manufacturing Ecosystem for Tavaborole

1. Key Regions for API Production

   • India: Leading API manufacturing hub with numerous API API APIs, including specialty pharmaceuticals and complex molecules. Indian firms are experienced in boron chemistry and complex organic synthesis, offering cost-effective manufacturing with a broad export capacity. Companies such as Sun Pharma and Lupin have demonstrated capabilities in high-quality API production, though specific API sourcing for tavaborole may involve specialized contract manufacturers.

   • China: An influential player in bulk API manufacturing, China offers extensive capacity for complex chemical APIs. Several Chinese API producers, such as Qilu Pharmaceutical and North China Pharmaceutical Group (NCPC), possess advanced synthesis facilities capable of producing boron-containing intermediates and active compounds at scale. Regulatory environment remains evolving, necessitating rigorous quality assessments.

   • Europe: A hub for high-quality API production adhering strictly to Good Manufacturing Practice (GMP) standards. European producers, including Dr. Reddy’s facilities in Germany and Nordic Chemicals, focus on high-value APIs with stringent quality control, suitable for markets with strict regulatory pathways.

   • United States: While the U.S. maintains a smaller number of API manufacturers, it offers high-quality, innovative production facilities with comprehensive regulatory oversight. Many U.S. firms produce APIs for biosimilar and specialty drugs, often under contract manufacturing agreements.

2. Contract Manufacturing Organizations (CMOs) and Contract Development and Manufacturing Organizations (CDMOs)

   The complex synthesis of tavaborole makes outsourcing a viable option. Major CMOs with experience in boron chemistry and complex APIs include Lonza, Catalent, and Boehringer Ingelheim. These firms provide scalable synthesis, GMP compliance, and regulatory support.

3. Raw Materials and Intermediates

   The synthesis of tavaborole requires boron reagents, aromatic compounds, and specialty intermediates—necessitating supply chain security for chemical raw materials. Suppliers like Alfa Aesar, Sigma-Aldrich, and TCI supply high-purity intermediates and boron reagents compatible with pharmaceutical manufacturing.
