Nortriptyline

methyl({3-[(2E)-tricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3(8),4,6,12,14-hexaen-2-ylidene]propyl})amine

C19H21N (263.1674)

Nortriptyline is an organic tricyclic compound that is 10,11-dihydro-5H-dibenzo[a,d][7]annulene substituted by a 3-(methylamino)propylidene group at position 5. It is an active metabolite of amitriptyline. It has a role as a drug metabolite, an antidepressant, an adrenergic uptake inhibitor, an analgesic, an antineoplastic agent and an apoptosis inducer. It is an organic tricyclic compound and a secondary amine. It is functionally related to an amitriptyline. It derives from a hydride of a dibenzo[a,d][7]annulene. Nortriptyline hydrochloride, the active metabolite of [amitriptyline], is a tricyclic antidepressant (TCA). It is used in the treatment of major depression and is also used off-label for chronic pain and other conditions. Nortriptyline is a Tricyclic Antidepressant. Nortriptyline is a tricyclic antidepressant that is also used in smoking cessation. Nortriptyline can cause mild and transient serum enzyme elevations and is rare cause of clinically apparent acute and chronic cholestatic liver injury. Nortriptyline is a natural product found in Senegalia berlandieri with data available. Nortriptyline is a tricyclic antidepressant agent used for short-term treatment of various forms of depression. Nortriptyline blocks the norepinephrine presynaptic receptors, thereby blocking the reuptake of this neurotransmitter and raising the concentration in the synaptic cleft in the CNS. Nortriptyline also binds to alpha-adrenergic, histaminergic and cholinergic receptors. Long-term treatment with nortriptyline produces a downregulation of adrenergic receptors due to the increased stimulation of these receptors. Nortriptyline hydrochloride, the N-demethylated active metabolite of amitriptyline, is a dibenzocycloheptene-derivative tricyclic antidepressant (TCA). TCAs are structurally similar to phenothiazines. They contain a tricyclic ring system with an alkyl amine substituent on the central ring. In non-depressed individuals, nortriptyline does not affect mood or arousal, but may cause sedation. In depressed individuals, nortriptyline exerts a positive effect on mood. TCAs are potent inhibitors of serotonin and norepinephrine reuptake. Secondary amine TCAs, such as nortriptyline, are more potent inhibitors of norepinephrine reuptake than tertiary amine TCAs, such as amitriptyline. TCAs also down-regulate cerebral cortical β-adrenergic receptors and sensitize post-synaptic serotonergic receptors with chronic use. The antidepressant effects of TCAs are thought to be due to an overall increase in serotonergic neurotransmission. TCAs also block histamine-H₁ receptors, α₁-adrenergic receptors and muscarinic receptors, which accounts for their sedative, hypotensive and anticholinergic effects (e.g. blurred vision, dry mouth, constipation, urinary retention), respectively. See toxicity section below for a complete listing of side effects. Nortriptyline exerts less anticholinergic and sedative side effects compared to the tertiary amine TCAs, amitriptyline and clomipramine. Nortriptyline may be used to treat depression, chronic pain (unlabeled use), irritable bowel syndrome (unlabeled use), diabetic neuropathy (unlabeled use), post-traumatic stress disorder (unlabeled use), and for migraine prophylaxis (unlabeled use). A metabolite of AMITRIPTYLINE that is also used as an antidepressive agent. Nortriptyline is used in major depression, dysthymia, and atypical depressions.

C19H21N (263.1674)

2-Ethyl-5-methyl-3,3-diphenyl-1-pyrroline is a metabolite of methadone. Methadone (also known as Symoron, Dolophine, Amidone, Methadose, Physeptone, Heptadon, Phy and many other names) is a synthetic opioid, used medically as an analgesic and a maintenance anti-addictive for use in patients with opioid dependency. It was developed in Germany in 1937. Although chemically unlike morphine or heroin, methadone acts on the same opioid receptors as these drugs, and thus has many of the same effects. (Wikipedia)
