Imipramine is believed to increase the synaptic concentration of serotonin and/or norepinephrine in the CNS by inhibition of their reuptake by the presynaptic neuronal membrane. However, additional receptor effects have been found including desensitisation of adenyl cyclase, down regulation of β-adrenergic receptors, and down regulation of serotonin receptors.
Imipramine should be used cautiously and with close physician supervision in people, especially the elderly, who have benign prostatic hypertrophy, urinary retention, and glaucoma, especially angle-closure glaucoma. The sedative effect is increased when imipramine is taken with other central nervous system depressants, such as alcoholic beverages, sleeping medications, other sedatives, or antihistamines. Imipramine may increase heart rate and stress on the heart. It may be dangerous for people with cardiovascular disease, especially those who have recently had a heart attack, to take this drug or other antidepressants in the same pharmacological class. Older people and persons with a history of heart disease may develop heart arrhythmias, heart conduction abnormalities, congestive heart failure, heart attack, abnormally rapid heart rates and strokes. Until a therapeutic dosage has been determined, people starting imipramine should be closely watched for signs of suicide. The risk of suicide is increased when imipramine is taken in overdose or combined with alcohol. Manic episodes and the emergence of symptoms of pre-existing psychotic states have been reported when imipramine therapy is started. In short-term studies, antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults (<24 years) taking antidepressants for major depressive disorders and other psychiatric illnesses. Patients should be monitored closely for changes in behavior, clinical worsening, and suicidal tendencies; this should be done during the initial 1-2 months of therapy and dosage adjustments Lactation: Distributed in breast milk; do not nurse (AAP states effect on nursing infants is unknown but may be of concern)
