Welireg(Belzutifan) Instructions:Uses,Dosage, Side Effects

WELIREG, with the active pharmaceutical ingredient belzutifan, is an orally administered medication available as 40 mg film-coated tablets. Chemically, belzutifan is 3-[[(1S,2S,3R)-2,3-Difluoro-2,3-dihydro-1-hydroxy-7-(methylsulfonyl)-1H-inden-4-yl]oxy]-5-fluorobenzonitrile. It is designed for therapeutic use in adult patients with specific oncological conditions, including tumors associated with von Hippel-Lindau disease and certain types of advanced kidney cancer.

The therapeutic effect of belzutifan is derived from its activity as an inhibitor of hypoxia-inducible factor 2 alpha (HIF-2αα). HIF-2αα is a key transcription factor that plays a significant role in the body's oxygen-sensing mechanisms by modulating genes involved in adaptation to hypoxic (low oxygen) conditions. By targeting and inhibiting HIF-2αα, WELIREG interferes with cellular pathways that contribute to the growth and progression of certain cancers.
