Bulk Active Pharmaceutical Ingredient (API) Sources for TARKA (Tadalafil)

Last updated: July 30, 2025

Introduction

Tadalafil, marketed under the brand name TARKA among others, is a phosphodiesterase type 5 (PDE5) inhibitor primarily used to treat erectile dysfunction, benign prostatic hyperplasia, and pulmonary arterial hypertension. As a critical component of the finished pharmaceutical product (FPP), the bulk Active Pharmaceutical Ingredient (API) sourcing for Tadalafil is central to maintaining supply chain integrity, ensuring drug quality, and optimizing costs. This article provides a comprehensive overview of the global API providers for Tadalafil, focusing on manufacturing capacities, regulatory compliance, and strategic sourcing considerations.
