timolol,sotalol,carteolol,propranolol,pindolol,penbutolol
Pindolol is a nonselective beta blocker with partial beta-adrenergic receptor agonist activity. It possesses ISA (Intrinsic Sympathomimetic Activity). This means that pindolol, particularly in high doses, exerts effects like epinephrine or isoprenaline (increased pulse rate, increased blood pressure, bronchodilation), but these effects are limited. Pindolol also shows membrane stabilizing effects like quinidine, possibly accounting for its antiarrhythmic effects. It also functions as a 5-HT1Areceptor weak partial agonist /
