Mechanism of action

Оглавление

Caffeine is a methylxanthine and exerts its effect through several mechanisms. It enhances catecholamines release, antagonizes cellular adenosine receptors and inhibits cellular phosphodiesterases thereby increasing intracellular cyclic AMP (AMPc) and calcium influx. Ephedrine is a sympathomimetic alkaloid with α-, β1- and β2-adrenergic agonist activity and CNS stimulatory effect.
