Depramine is a dibenzazepine derivative. Its chemical structure is related to imipramine and it has antidepressant effects as well as anti-Parkinson effects. Dimepramine fumarate is an anticholinergic agent and inhibits the uptake of norepinephrine. The anticataleptic effect of dimepramine fumarate is attributed to its anticholinergic properties and to its probable role in central adrenergic and/or dopaminergic stimulation. The drug tends to decrease autonomic arousal responses of Parkinson patients as measured by resting conductance levels, number of fluctuations in skin conduction per minute, orienting response, and habituation rate. Depramine is used for the treatment of obsessive compulsive disorder, obsessions and phobias, panic disorder, cataplexy associated with narcolepsy, major depressive disorder, and chronic pain. It can help ease the symptoms in each of these conditions. It works by interfering with the brain chemical serotonin. Side effects of depramine are: dizziness, irritability, blurred vision, dry mouth, nausea or vomiting, swelling of face and feet, acid or sour stomach, constipation, shaking of hands or feet, mouth ulcers, irregular menstrual periods.
