Pharco Corporation

Pharmacological action

Beta adrenoagonists with a predominant effect on beta2-adrenergic receptors (localized, particularly in the bronchi, myometrium, blood vessels).
This medication prevents and reduces or eliminates bronchospasm, reduces the resistance in the airways, increases the vital capacity. It prevents the release of histamine, slow reacting substance from mast cells and factors chemotaxis of neutrophils. Compared with other drugs of this group has a less pronounced positive chrono-and inotropic effect on myocardium. It widen of coronary arteries, practically does not reduce blood pressure. Has tocolytic effect, lowering the tone and the contractile activity of the myometrium.

Pharmacokinetics

When using an aerosol there is a rapid absorption of albuterol (salbutamol) in the blood, but its concentration in plasma when used in recommended doses are very low or below detection limit.
After oral salbutamol is well absorbed from the gastrointestinal tract. Plasma protein binding is 10%. Metabolised with "first pass" through the liver and possibly in the wall of the intestine, the main metabolite - inactive sulfate conjugate. salbutamol is not metabolised in the lungs, thus its ultimate metabolism and excretion following inhalation depends on the method of application, which defines the relationship between inhaled salbutamol and unintentionally swallowed.
T1/2 from plasma is 2-7 hours. albuterol (salbutamol) is rapidly excreted in the urine as metabolites and unchanged substance, in small amounts excreted in the feces.
