Answer

Tricyclic Antidepressants

Tricyclic antidepressants (TCAs) increase the levels of certain brain chemicals which improve mood and regulate pain signals. Low doses of TCAs relieve pain, although its mechanism is still unknown.

Amitriptyline (Elavil)

Amitriptyline inhibits presynaptic reuptake of serotonin and norepinephrine and blocks cholinergic, adrenergic, histaminergic, and sodium channels.

Nortriptyline (Pamelor)

Nortriptyline may increase the synaptic concentration of serotonin and/or norepinephrine in the CNS by reuptake inhibition via the presynaptic neuronal membrane; inhibits the activity of histamine, 5-hydroxytryptamine, and acetylcholine. It increases the pressor effect of norepinephrine but blocks the pressor response of phenethylamine.
