Mechanism and action
Ventolin: Albuterol selectively activates beta-2 adrenergic receptors on bronchial smooth muscle, leading to relaxation of the airways and rapid bronchodilation within five to fifteen minutes. Propecia: DHT, produced from testosterone by 5-alpha-reductase, drives miniaturisation of scalp hair follicles in genetically susceptible men, gradually shortening anagen growth phases until follicles produce only fine vellus hair…
