Adrenergic Drugs
(Sympathomimetics)
These are drugs with actions similar to that
of Adr or of sympathetic stimulation.
Direct Sympathomimetics
They act directly as agonists
on α and/or β adrenoceptors —Adr,
NA, isoprenaline (Iso), phenylephrine, methoxamine, xylometazoline, salbutamol
and many others.
Indirect Sympathomimetics
They act on adrenergic neurone to release NA, which then acts on the adrenoceptors—tyramine, amphetamine.
Mixed Action Sympathomimetics
They
act directly as well as indirectly—ephedrine, dopamine, mephentermine.
