Benzcyclane (Bencyclane; Benzcyclan) is a platelet aggregation inhibitor and a vasodilator effective in a variety of peripheral circulation disorders.
Benzcyclane, although capable of aggregating platelets by itself at very high concentrations, shows a striking inhibitory effect, over a wide range of concentrations, both on platelet aggregation induced by ADP, epinephrine or collagen and on platelet adhesiveness to glass or collagen. Clot retraction is also clearly inhibited[1]. Benzcyclane induces use-dependent inhibition of Na channels in muscle, similarly as do class 1 antiarrhytnmic drugs. Inhibition was observed with both normal and cevadine-modified Na channels[2].
