Ro 22-9194 is a new class I antiarrhythmic agent. Ro 22-9194 (?10 μM) caused a concentration-dependent decrease in the maximum upstroke velocity (V?max) and shortening of action potential duration in guinea-pig ventricular cells. | [Uses]
Ro 22-9194 inhibits aggregation and thromboxane Az (TXA2) synthetase activity in rabbit and human platelets. Ro 22-9194 has a potent inhibitory action against various types of model arrhythmias. Ro 22-9194 has non-cholinergic cardiac depressant properties with its vasodilating action[1][2]. | [References]
