How Troglitazone’s Hepatotoxicity Changed Drug Development Forever — and Why It Still Matters Today Troglitazone (Rezulin), introduced by Warner-Lambert and later absorbed by Pfizer, was once celebrated as a breakthrough insulin-sensitizing therapy for type 2 diabetes. Within a few years, it became one of the most catastrophic toxicology failures in FDA history — linked to idiosyncratic yet sometimes fatal liver injury, multiple cases of acute liver failure, and a full U.S. market withdrawal in 2000.

According to The Hill, a widely used high-blood-pressure medication was voluntarily recalled after FDA testing identified contamination and quality issues that could pose serious risks to patients. https://thehill.com/policy/healthcare/5636604-high-blood-pressure-medication-voluntarily-recalled-fda Why do these recalls keep happening? Because wherever chemistry, manufacturing, and patient exposure intersect — toxicology decides the outcome. Here’s the one idea you should take away:

Pharmaceuticals enter the environment via patient excretion, improper disposal, and manufacturing waste, prompting regulators worldwide to require environmental risk assessments (ERAs) as part of drug approvals. In an ERA, predicted environmental concentrations (PECs) of a drug are compared to ecotoxicity thresholds, often in a tiered fashion (Phase I screening followed by Phase II testing) [1]. This report analyzes ERA regulations and practice globally, from the EU and US to emerging regions in Asia, Latin America, the Middle East, and Africa. It integrates recent developments in China, India, Brazil, the Gulf Cooperation Council (GCC) countries, ASEAN nations, and African markets, alongside established frameworks (EU, US, Canada, Japan, Australia). Key findings include:
