Pharmacologie
Metaproterenol, une amine synthétique, est structurellement et pharmacologiquement analogue à l'isoprotérénol. Metaproterenol est utilisé exclusivement comme un bronchodilatateur. Les effets pharmacologiques des agonistes bêta-adrénergiques médicaments, tels que Metaproterenol, sont au moins en partie attribuable à la stimulation par le biais des récepteurs bêta-adrénergiques adénylcyclase intracellulaire, l'enzyme qui catalyse la conversion de l'adénosine triphosphate (ATP) pour cyclique-3 ', 5'-adénosine monophosphate (AMP-c). Augmentation de c-AMP niveaux sont associées à la relaxation des muscles lisses bronchiques et l'inhibition de la libération de médiateurs de l'immédiate hypersensibilité à partir des cellules, en particulier par les mastocytes.
