Biochem/physiol Actions

Fimasartan (BR-A-657) is an orally active, highly potent angiotensin II receptor AT1 (AGTR1) antagonist (blocker) that selectively blocks AngII-, but not KCl- or noradrenaline-, induced contraction of rabbit thoracic aortic rings (IC50 = 0.42 nM) with 615-fold higher AT1 affinity than losartan (IC50 = 0.13 nM vs. 80 nM against 0.05 nM AngII for binding rat adrenal cortex). Fimasartan significantly decreases mean arterial blood pressure with rapid onset (in 0.5 h) in spontaneously hypertensive rats (Emax of 75% reduction, 5-24 hr post 10 mg/kg p.o.) and is ~19-fold more effective than losartan against AngII (100 ng/kg i.v.)-induced pressor response in rats in vivo (ED50 = 18 ng/kg vs. 336 ng/kg i.v.).
Orally active, highly potent angiotensin II receptor AT1 (AGTR1) antagonist with superior in vivo antihypertensive efficacy than Losartan.
