Associated Conditions
Pharmacodynamics
Nevola Tablet (Extended Release) 50 mg is a selective serotonin and norepinephrine reuptake inhibitor. It lacks significant activity on muscarinic-cholinergic, H1-histaminergic, or α1-adrenergic receptors in vitro. Nevola Tablet (Extended Release) 50 mg does not appear to exert activity against calcium, chloride, potassium and sodium ion channels and also lacks monoamine oxidase (MAO) inhibitory activity. It was also shown to lack significant activity again the cardiac potassium channel, hERG, in vitro. Compared to other SNRIs, desvenlafaxine undergoes simple metabolism, has a low risk of drug-drug interactions and does not have to be extensively titrated to reach a therapeutic dose.
Mechanism of Action
Nevola Tablet (Extended Release) 50 mg, the active metabolite of venlafaxine, is a selective serotonin and norepinephrine reuptake inhibitor. Nevola Tablet (Extended Release) 50 mg inhibits neurotransmitter reuptake in serotonin, norepinephrine, and dopamine transporters. Nevola Tablet (Extended Release) 50 mg inhibits serotonin transporters with 10 times the affinity of norepinephrine transporters, and dopamine transporters with the lowest affinity. In vitro, desvenlafaxine has no inhibition of monoamine oxidase, and almost no affinity for muscarinic, cholinergic, H1-histaminergic, and alpha1-adrenergic receptors.
