Description

General description

With heat. Aqueous solutions are most stable at pH 3.0 and decompose rapidly at basic pH. Decomposition is accompanied by discoloration of the solution.

Application

(S)-(−)-Propranolol hydrochloride has been used:

• as a non-selective β-blocker propranolol to inhibit the actions of epinephrine in mice
• as a β1- and β2-aadrenergic receptor blocker in rat
• as a medium supplement to investigate its effect on adipogenesis in hemangioma-derived stem cells (HemSC)

Biochem/physiol Actions

(S)-(−)-Propranolol hydrochloride is biologically active enantiomer. It acts as β1 receptor antagonist in thalamocortical neurons. (S)-(−)-Propranolol hydrochloride elicits its inhibitory function on the β1 adrenoceptor in trigeminovascular pain pathway and serves as a preventive medicine in migraine.

Active β-adrenoceptor blocking enantiomer, as measured by inhibition of isoprenaline-induced tachycardia; Propranolol is also non-specific 5-HT_1A, 5-HT_1B and 5-HT_1C serotonin receptor antagonist. The stereoselective association of mianserin and propranolol with the 5HT_1A, 5HT_1B and 5HT_1C sites may prove useful in the characterization of these sites
