Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Propranolol is a non-selective beta receptor antagonist. It competes with sympathomimetic neurotransmitters for binding to receptors, which inhibits sympathetic stimulation of the heart. Blockage of neurotransmitter binding to β1 receptors on cardiac myocytes inhibits activation of adenylate cyclase, which in turn inhibits cAMP synthesis leading to reduced PKA (Protein Kinase A) activation. This results in less calcium influx to cardiac myocytes through voltage gated L-type calcium channels meaning there is a decreased sympathetic effect on cardiac cells, resulting in antihypertensive effects including reduced heart rate and lower arterial blood pressure Blockage of neurotransmitter binding to β2 receptors on smooth muscle cells will increase contraction, which will increase hypertension.
