    PHARMACOLOGY
    Pharmacotherapeutic Group:
    β2 adrenoreceptor agonist.

     Pharmacodynamic Properties:Salbutamol is a β2 adrenergic agonist and thus it stimulates β2 adrenergic receptors. Binding of salbutamol to the β2 receptors results in the relaxation of the bronchial smooth muscles. Salbutamol also inhibits the release of bronchoconstricting agentsfrom the mast cells, inhibits the microvascular leakage and enhances the muciliary clearance.

     Pharmacokinetic Properties:

    Absorption: Readily absorbed from the GIT; Onset: 30min; Duration: 8 hr.

    Metabolism: Hepatic and in the gut wall

    Excretion: Via the urine as metabolites and unchanged drug. Some excretion in the faeces.
