Etripamil (MSP-2017) displays atrioventricular nodal conduction and prolongs atrioventricular nodal refractory periods by inhibiting calcium ion influx through the calcium slow channels in the atrioventricular node cells. Etripamil is an antagonist of short-acting L-type calcium-channel. It has a rapid onset of action designed for intranasal administration. It is also used to treat Paroxysmal Supraventricular Tachycardia.
