PubChem Compound ID: | 11130244 |
Description: | A tricyclic dibenzazepine compound that potentiates neurotransmission. Desipramine selectively blocks reuptake of norepinephrine from the neural synapse, and also appears to impair serotonin transport. This compound also possesses minor anticholinergic activity, through its affinity to muscarinic receptors. |
Molecular formula: | C18H22N2 |

CAS number: | 50-47-5 |
Indication: | For relief of symptoms in various depressive syndromes, especially endogenous depression. It has also been used to manage chronic peripheral neuropathic pain, as a second line agent for the management of anxiety disorders (e.g. panic disorder, generalized anxiety disorder), and as a second or third line agent in the ADHD management. |

Pharmacology: |
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, a tertiary amine TCA. The acute effects of desipramine include inhibition of noradrenaline re-uptake at noradrenergi...

Mechanism of Action: |
Desipramine is a tricyclic antidepressant (TCA) that selectively blocks reuptake of norepinephrine (noradrenaline) from the neuronal synapse. It also inhibits serotonin reuptake, but to a lesser extent compared to tertiary amine TCAs such as imipramine. Inhibition of neurotransmitter reuptake increases stimulation of the post-synaptic neuron. Chro...

Absorption: | Desipramine hydrochloride is rapidly and almost completely absorbed from the gastrointestinal tract. It undergoes extensive first-pass metabolism. Peak plasma concentrations are attained 4 - 6 hours following oral administration. |
Protein binding: | 73-92% bound to plasma proteins |
Biotransformation: | Desipramine is extensively metabolized in the liver by CYP2D6 (major) and CYP1A2 (minor) to 2-hydroxydesipramine, an active metabolite. 2-hydroxydesipramine is thought to retain some amine reuptake inhibition and may possess cardiac depressant activity. The 2-hydroxylation metabolic pathway of desipramine is under genetic control. |
Route of elimination: | Desipramine is metabolized in the liver, and approximately 70% is excreted in the urine. |
Half Life: | 7-60+ hours; 70% eliminated renally |
Toxicity: | Male mice: LD50 = 290 mg/kg, female rats: LD50 = 320 mg/kg. Antagonism of the histamine H1 and α1 receptors can lead to sedation and hypotension. Antimuscarinic activity confers anticholinergic side effects such as blurred vision, dry mouth, constipation and urine retention may occur. Cardiotoxicity may occur with high doses of desipramine. Cardiovascular side effects in postural hypotension, tachycardia, hypertension, ECG changes and congestive heart failure. Psychotoxic effects include impaired memory and delirium. Induction of hypomanic or manic episodes may occur in patients with a history of bipolar disorder. Withdrawal symptoms include GI disturbances (e.g. nausea, vomiting, abdominal pain, diarrhea), anxiety, insomnia, nervousness, headache and malaise. |
