1,3-dimethylamylamine is a sympathomimetic amine, meaning it mimics norepinephrine, which revs up the metabolic rate of muscle cells, increases fat mobilization and kicks up alertness in a big way.
Mechanisms of action
The mechanisms of sympathomimetic drugs can be direct-acting, such as α-adrenergic agonists, β-adrenergic agonists, dopaminergic agonists; or indirect-acting, such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors.
Direct-acting
Adrenergic receptor agonists
Main article: Adrenergic agonist
Direct stimulation of the α- and β-adrenergic receptors can produce sympathomimetic effects. Albuterol is a very commonly used direct-acting β2-agonist. Other examples include phenylephrine, isoproterenol, and dobutamine.
Like ephedrine, a beta-agonist, a tolerance is developed, but simply because the stimulant effect is no longer accute does not mean it is not working on your beta receptors.
