Desipramine

فارسی

Desipramine is a tricyclic antidepressant. Desipramine affects chemicals in the brain that may be unbalanced in people with depression. Desipramine is used to treat symptoms of depression.

Mechanism of effect

Available evidence suggests that many depressions have a biochemical basis in the form of a relative deficiency of neurotransmitters such as norepinephrine and serotonin. Norepinephrine deficiency may be associated with relatively low urinary 3-methoxy-4-hydroxyphenyl glycol (MHPG) levels, while serotonin deficiencies may be associated with low spinal fluid levels of 5-hydroxyindoleacetic acid.

Pharmacodynamic

Desipramine, a secondary amine tricyclic antidepressant, is structurally related to both the skeletal muscle relaxant cyclobenzaprine and the thioxanthene antipsychotics such as thiothixene. It is the active metabolite of imipramine

Pharmacokinetics

Peak plasma concentrations are attained 4 - 6 hours following oral administration. Protein binding:73-92% bound to plasma proteins. Desipramine is extensively metabolized in the liver approximately 70% is excreted in the urine. Half life:7-60+ hours.
