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.
