Aprindine is a class Ib antiarrhythmic agent. It is not approved in USA, but is available in European countries, where it is used to treat supraventricular and ventricular arrhythmias. Aprindine acts by blocking sodium voltage channels and disrupting interactions between calmodulin and prosphodiesterase.

Sample Use Guides
150-200 mg daily in divided doses, up to 300 mg/day may be used under strict observation for the first 2-3 days if needed.
Route of Administration:
Oral
Effects of aprindine (3 umol/l) on the Na+ current using whole cell voltage clamp was studied in guinea-pig ventricular myocytesd. Aprindine revealed tonic block (Kdrest = 37.7 umol/l, Kdi = 0.74 umol/l) and shifted inactivation curve to hyperpolarizing direction by 11.4+3.5 mV (n = 4) without changes in slope factor.
