Answer

Tricyclic Antidepressants

A complex group of drugs that has central and peripheral anticholinergic effects, as well as sedative effects. They have central effects on pain transmission, blocking the active reuptake of norepinephrine and serotonin.

Amitriptyline (Elavil)

Analgesic for certain chronic and neuropathic pain. Inhibits membrane pump responsible for uptake of norepinephrine and serotonin in adrenergic and serotonergic neuron.

Nortriptyline (Pamelor)

Has demonstrated effectiveness in the treatment of chronic pain. By inhibiting the reuptake of serotonin and/or norepinephrine by the presynaptic neuronal membrane, this drug increases the synaptic concentration of these neurotransmitters in the central nervous system.

Pharmacodynamic effects, such as the desensitization of adenyl cyclase and down-regulation of beta-adrenergic receptors and serotonin receptors, also appear to play a role in its mechanisms of action.

Doxepin (Sinequan)

Inhibits histamine and acetylcholine activity and has proven useful in treatment of various forms of depression associated with chronic and neuropathic pain.

Desipramine (Norpramin)

May increase synaptic concentration of norepinephrine in CNS by inhibiting reuptake by presynaptic neuronal membrane. May have effects in the desensitization of adenyl cyclase, down-regulation of beta-adrenergic receptors, and down-regulation or serotonin receptors.
