Bulk Active Pharmaceutical Ingredient (API) Sources for VIREAD (Tenofovir Disoproxil Fumarate)

Last updated: August 1, 2025

Introduction

VIREAD, the brand name for Tenofovir Disoproxil Fumarate (TDF), is a cornerstone antiviral medication used in managing HIV-1 infection and chronic hepatitis B. As a prodrug of tenofovir, TDF demonstrates potent activity against these viruses through inhibition of reverse transcriptase. The quality, purity, and supply reliability of TDF APIs directly influence the efficacy and safety of VIREAD. The global API sourcing landscape for TDF has evolved significantly, with key suppliers dominating the market, adhering to pharmaceutical standards, and navigating regulatory requirements. This report provides a detailed overview of primary sources supplying bulk TDF API critical for VIREAD production.
