Bupranolol is a non-selective beta blocker without intrinsic sympathomimetic activity (ISA), but with strong membrane stabilizing activity. Bupranolol competes with sympathomimetic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart, inhibiting sympathetic stimulation. This results in a reduction in resting heart rate, cardiac output, systolic and diastolic blood pressure, and reflex orthostatic hypotension. Ophthalmic Bupranolol is used for the management of glaucoma and oral Bupranolol is used for the management of cardiovascular disorders. S-Bupranolol has also being shown to have superior preclinical safety profile and great antinociceptive efficacy and should be considered as a unique b-AR compound to advance future clinical pain studies.

Sample Use Guides

In Vivo Use Guide

Bupranolol is usually given in doses of 100 mg twice daily in the treatment of hypertension

Route of Administration: Oral

In Vitro Use Guide

In the human detrusor bupranolol (a nonselective β-AR antagonist) at a low concentration (10(-8) M) did not inhibit isoproterenol-induced relaxation, but at higher concentrations (10(-7)-10(-5) M), the drug caused a rightward shift of the concentration-relaxation curve for isoproterenol in a dose-dependent manner
