Phenamine is chemically a phenylalkylamine, i.e.
its structure is similar to Noradrenaline and Adrenaline.
It has the same pharmacological profile as Ephedrine; orally active with long duration (4-6 hours).
Mechanism of action. Phenamine acts primarily by
releasing noradrenaline and dopamine in the brain,
inhibits catecholamines reuptake, MAO activity and
increases receptors sensitivity to catecholamines.
Clinical uses: attention deficit disorder,
narcolepsy (an uncontrollable desire for sleep).

pharmacologically similar to
phenamine but does not cause drug dependence,
