| Common Name | Imipramine |

| Description | Imipramine, also known as tofranil or imizine, belongs to the class of organic compounds known as dibenzazepines. Dibenzazepines are compounds with two benzene rings connected by an azepine ring. Azepine is an unsaturated seven-member heterocycle with one nitrogen atom replacing a carbon atom. A dibenzoazepine that is 5H-dibenzoazepine substituted by a 3-(dimethylamino)propyl group at the nitrogen atom. Imipramine is a drug which is used for the relief of symptoms of depression and as temporary adjunctive therapy in reducing enuresis in children aged 6 years and older [fda label].
may also be used off-label to manage panic disorders with or without agoraphobia, as a second line agent for adhd in children and adolescents, to manage bulimia nervosa, for short-term management of acute depressive episodes in bipolar disorder and schizophrenia, for the treatment of acute stress disorder and posttraumatic stress disorder, and for symptomatic treatment of postherpetic neuralgia and painful diabetic neuropathy [l1349,l1348,a31900,l1351,l1352,l1353,a31904]. . Imipramine is a very strong basic compound (based on its pKa). Within humans, imipramine participates in a number of enzymatic reactions. In particular, imipramine can be converted into 2-hydroxyimipramine; which is mediated by the enzyme cytochrome P450 2D6. In addition, imipramine can be converted into desipramine and formaldehyde; which is mediated by the enzymes cytochrome P450 2C19, cytochrome P450 1A2, and cytochrome P450 3A4. In humans, imipramine is involved in imipramine action pathway. Imipramine is a potentially toxic compound. |
