  • 1 The electrophysiological effects of bepridil, its quaternary derivative, CERM 11888 (methylpyrrolidinium bromide) (both 2.5 mg kg−1 i.v.) and those of verapamil and diltiazem (0.2 mg kg−1 i.v.) were studied in closed chest anaesthetized dogs at doses used in clinical studies. 2 The four drugs caused a bradycardia with the following order of potency: bepridil > CERM 11888 > diltiazem > verapamil. 3 All the compounds slowed conduction in the AV node, increased the refractory period (RP) and… CONTINUE READING
