beta-adrenergic blocker

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
Betablocker (beta-adrenergic blocker)
A class of drugs that bind beta-adrenergic receptors and thereby decrease the ability of the body's own natural epinephrine to bind to those receptors, leading to inhibition of various processes in the body's sympathetic system. Betablockers can slow the heart rate, constrict airways in the lungs, lower blood pressure, and reduce aqueous secretion by ciliary tissues in the eye.

This presentation concluded that CK-1122534 increases the fractional shortening in ventricular myocytes (a measure of cardiac contractility) in a dose-dependent manner, does not increase the calcium transient, does not inhibit phosphodiesterase (PDE) activity and is active in the presence of a beta-adrenergic blocker.
Furthermore, Cytokinetics presented results that demonstrated that CK-1122534 does not increase the calcium transient and does not inhibit phosphodiesterase activity and that the attendant increase in fractional shortening is not attenuated by the addition of a beta-adrenergic blocker, altogether providing evidence that CK-1122534 increases myocyte contractility by directly activating cardiac myosin.
