Nortin Capsule 10 mg
Nortin Capsule 10 mg Uses, Dosage, Side Effects, Food Interaction and all others data.
Nortin Capsule 10 mg, a dibenzocycloheptadiene tricyclic antidepressant, is the primary active metabolite of amitriptyline. It increases synaptic concentration of serotonin and/or norepinephrine in the CNS by blocking the neuronal reuptake of norepinephrine and serotonin.
Nortin Capsule 10 mg exerts antidepressant effects likely by inhibiting the reuptake of serotonin and norepinephrine at neuronal cell membranes. It also exerts antimuscarinic effects through its actions on the acetylcholine receptor.

How Nortin Capsule 10 mg works
Though prescribing information does not identify a specific mechanism of action for nortriptyline, is believed that nortriptyline either inhibits the reuptake of the neurotransmitter serotonin at the neuronal membrane or acts at the level of the beta-adrenergic receptors. It displays a more selective reuptake inhibition for noradrenaline, which may explain increased symptom improvement after nortriptyline therapy. Tricyclic antidepressants do not inhibit monoamine oxidase nor do they affect dopamine reuptake. As with other tricyclics, nortriptyline displays affinity for other receptors including mACh receptors, histamine receptors, 5-HT receptors, in addition to other receptors.

Nortin Capsule 10 mg Alcohol interaction
[Moderate] GENERALLY AVOID:
Concomitant use of ethanol and a tricyclic antidepressant (TCA) may result altered TCA plasma levels and efficacy, and additive impairment of motor skills, especially driving skills.
Acute ethanol ingestion may inhibit TCA metabolism, while chronic ingestion of large amounts of ethanol may induce hepatic TCA metabolism.
Patients should be advised to avoid alcohol during TCA therapy.
Alcoholics who have undergone detoxification should be monitored for decreased TCA efficacy.
Dosage adjustments may be required.
