List of adrenergic drugs

This is a list of adrenergic drugs. These are pharmaceutical drugs, naturally occurring compounds and other chemicals that influence the function of the neurotransmitter epinephrine (adrenaline).
Receptor ligands.
α1-adrenergic receptor ligands.
Antagonists.
Many tricyclic antidepressants, tetracyclic antidepressants, antipsychotics, ergolines, and some piperazines like buspirone, trazodone, nefazodone, etoperidone, and mepiprazole antagonize α1-adrenergic receptors as well, which contributes to their side effects such as orthostatic hypotension.
α2-adrenergic receptor ligands.
Antagonists.
Many atypical antipsychotics and azapirones like buspirone and gepirone (via metabolite pyrimidinylpiperazine) antagonize α2-adrenergic receptors as well.
Enzyme inhibitors.
Catabolism.
Monoamine oxidase (MAO) inhibitors.
MAO-B inhibitors also influence norepinephrine/epinephrine levels since they inhibit the breakdown of their precursor dopamine.
