    Product Description

    Buflomedil is a non-selective antagonist of α-adrenergic receptors (α-ARs) and vasoactive compound.1,2,3,4 It binds to rat α1A- and α1B-ARs (Kis = 4.06 and 6.84 µM, respectively) and human platelet α2-ARs (IC50 = 1 µM) in radioligand binding assays.1,2 Buflomedil (0.06-60 µM) inhibits contraction of isolated canine saphenous veins induced by phenylephrine, clonidine (Item No. 15949), sympathetic nerve stimulation, or norepinephrine.3 It inhibits ADP-, collagen-, or epinephrine-induced aggregation of isolated human platelets when used at a concentration of 100 µM.2 Buflomedil (10 mg/kg) reduces hippocampal neuronal cell death in a rat model of carotid clamping-induced ischemia-reperfusion injury.4
