Introduction
Temodar (generic: temozolomide) remains a cornerstone in the treatment of high-grade gliomas, notably glioblastoma multiforme, and certain anaplastic astrocytomas. As a chemotherapeutic agent, its efficacy hinges significantly on reliable sourcing from established suppliers. This report provides a comprehensive overview of key pharmaceutical suppliers for Temodar, assesses their market positioning, and explores implications for healthcare providers and stakeholders in the pharmaceutical supply chain.
Overview of Temozolomide
Temozolomide, an oral alkylating agent, was first approved by the U.S. Food and Drug Administration (FDA) in 1999. Its patent, initially held by Schering-Plough, led to subsequent acquisition by Merck & Co., which now markets Temodar as a branded product. Its widespread usage necessitates a robust supply network, including branded and generic versions.
