General Description:

Racepinephrine, identified by CAS number 329-65-7, is a notable compound with significant therapeutic applications. Racepinephrine is a racemic mixture consisting of d- and l- enantiomers. Epinephrine is a non-selective α- and β-adrenergic receptor agonist. It is a bronchodilator used in the temporary relief of mild symptoms of intermittent asthma including wheezing, tightness of chest and shortness of breath. It is an active ingredient in oral inhalation over-the-counter products as racepinephrine hydrochloride.

Pharmacodynamics:

Racepinephrine exerts its therapeutic effects through: Epinephrine acts on α- and β-adrenergic receptors. When given subcutaneously or intramuscularly, epinephrine has a rapid onset and short duration of action . Epinephrine induces bronchial smooth muscle relaxation to relieve respiratory distress in asthma. In a clinical trial of paediatric patients with bronchiolitis, administration of aerosolized racemic epinephrine via inhalation resulted in improved clinical symptoms such as wheezing and retractions . The clinical efficacy of racemic epinephrine was comparable to that of salbutamol or albuterol, which are commonly used bronchodilators . The drug's ability to modulate various physiological processes underscores its efficacy in treating specific conditions.

Mechanism of Action:

Racepinephrine functions by: Epinephrine is a non-selective agonist at α- and β-adrenergic receptors, which are all G-protein-coupled receptors. The main therapeutic effect of epinephrine arises from its agonist action on β2-adrenergic receptors, which activate adenylyl cyclase and increase intracellular cyclic AMP production. Epinephrine causes smooth muscle relaxation on various tissues, including bronchial smooth muscles . As a result, epinephrine serves to alleviate bronchospasm, wheezing and tightness of chest that may occur during asthmatic attacks . Via its relaxer effects on the smooth muscle of the stomach, intestine, uterus and urinary bladder, epinephrine may also alleviate pruritus, urticaria, and angioedema and may relieve gastrointestinal and genitourinary symptoms associated with anaphylaxis. Epinephrine also acts on the α-adrenergic receptors on vascular smooth muscles, particularly in the skin and splanchnic vascular beds, to cause constriction. Epinephrine is thought to reduce capillary leakage by constricting precapillary arterioles, reducing hydrostatic pressure and consequently bronchial mucosal edema . This mechanism highlights the drug's role in inhibiting or promoting specific biological pathways, contributing to its therapeutic effects.
