 Use of Etripamil


Etripamil (MSP-2017) is a short-acting L-type calcium-channel antagonist with a rapid onset of action designed for intranasal administration, used to treat Paroxysmal Supraventricular Tachycardia (PSVT). Etripamil (MSP-2017) slows atrioventricular nodal conduction and prolongs atrioventricular nodal refractory periods by inhibiting calcium ion influx through the calcium slow channels in the atrioventricular node cells[1][2].
