Adaprolol maleate

还可以

Adaprolol maleate is a beta-blocker and opthalmic which may be used in the treatment of Glaucoma or other ailments of the eye. Adaprolol has marked electrophysiologic effects. Its major action was on sinus node; it prolonged the basic sinus cycle length and had significant effect on intrinsic automaticity as reflected by the prolonged corrected sinus node recovery time and sinuatrial conduction time. There was, also, direct effect on atrial function and AV nodal function. Adaprolol prolonged the effective refractory period of the His-Purkinje system and the ventricle. The potency of adaprolol's electrophysiologic effects are higher compared to other widely used beta-blockers. Adaprolol appears to be a potent beta-blocker with particularly strong antiarrhythmic effect and it would be very useful in the treatment of both supraventricular and ventricular tachyarrhythmias and ectopic beats.
