Background Information

Bisoprolol fumarate is a selective type β1 adrenergic receptor blocker. ......by AbMole BioScience
Bisoprolol is a beta-adrenoceptor blocking drug (beta-blocker). More specifically, it is a selective type β1 adrenergic receptor blocker. ......by BOC Sciences
Bisoprolol hemifumarate is a cardioselective beta-1 adrenergic blocker. It is effective in the management of hypertension and angina pectoris. Bisoprolol hemifumarate has antihypertensive and potential cardioprotective activities. Devoid of intrinsic sympathomimetic activity, bisoprolol selectively and competitively binds to and blocks beta-1 adrenergic receptors in the heart, decreasing cardiac contractility and rate, reducing cardiac output, and lowering blood pressure. ......by MedKoo Biosciences, Inc.
A cardioselective beta-1 adrenergic blocker. It is effective in the management of HYPERTENSION and ANGINA PECTORIS. ......by Target Molecule Corp.
A selective β1-adrenergic antagonist. Has a Kd of 2-3 nM at the β1 receptor and a β1/β2 selectivity of approximately 100-fold. ......by Tocris Bioscience Inc.
