Description

General description

dissolve 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.

Propranolol hydrochloride is easily soluble in ethanol and water.

Application

(±)-Propranolol hydrochloride has been used:

• to determine whether autonomic nervous system mediated the promotive effect on skin microcirculation in rat
• as a non-selective β- receptor blocker to reduce the arrhythmogenic events
• to study its effect on oxygen-induced retinopathy in mice

Biochem/physiol Actions

Propranolol hydrochloride is a β-adrenoceptor antagonist. Its action at β2 receptor results in bronchoconstriction. Due to its lipophilic nature, propranolol can penetrate to the central nervous system and has a negative effect. It serves as a 5-HT₁/5-HT₂ serotonin receptor antagonist. Propranolol hydrochloride is useful as an antihypertensive drug, cardiac depressant and also in the treatment of angina pectoris. It decreases the effect of stress and exercise on heart by reducing the rate of contraction and conduction of impulse. It is known to competitively block the action of catecholamines.
