Desvenlafaxine succinate is used in the treatment of major depressive disorder in adults. /Included in US product labeling/

Recent reviews have questioned whether the serotonin-norepinephrine reuptake inhibitor (SNRI) desvenlafaxine succinate offers any practical clinical advantages over existing SNRIs. The following case is one instance where it appears that this SNRI offers unique safety and benefit. Presented is a case report of a patient with Gilbert's syndrome, longstanding social phobia, and more recent depressive disorder not otherwise specified, who was found to have elevated liver transaminases when prescribed both duloxetine and venlafaxine. The patient subsequently responded to desvenlafaxine but without liver abnormalities. In this patient with Gilbert's Syndrome, desvenlafaxine's lack of metabolism through the cytochrome P450 (CYP) 2D6 pathway may explain the avoidance of these abnormalities and thus suggests a possible therapeutic role for this SNRI in similarly susceptible patients.

4.3 Drug Warning

/BOXED WARNING/ WARNING: SUICIDAL THOUGHTS AND BEHAVIORS. Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies. These studies did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in patients over age 24; there was a reduction in risk with antidepressant use in patients aged 65 and older. In patients of all ages who are started on antidepressant therapy, monitor closely for worsening, and for emergence of suicidal thoughts and behaviors. Advise families and caregivers of the need for close observation and communication with the prescriber. Pristiq is not approved for use in pediatric patients.

US Natl Inst Health; DailyMed. Current Medication Information for PRISTIQ (desvenlafaxine succinate) tablet, extended release (Updated: March 2015). Available from, as of April 23, 2015: https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=0f43610c-f290-46ea-d186-4f998ed99fce


In patients with moderate or severe renal impairment or end-stage renal disease (ESRD) the clearance of Pristiq was decreased, thus prolonging the elimination half-life of the drug. As a result, there were potentially clinically significant increases in exposures to Pristiq. Dosage adjustment (50 mg every other day) is necessary in patients with severe renal impairment or ESRD. The doses should not be escalated in patients with moderate or severe renal impairment or ESRD.

Sustained increases in blood pressure have been reported. In controlled studies, sustained hypertension occurred in 0.7-2.3% of patients receiving desvenlafaxine dosages from 50-400 mg daily, with a suggestion of a higher incidence (2.3%) in those receiving 400 mg of the drug daily. In addition, some cases of elevated blood pressure requiring immediate treatment have been reported with desvenlafaxine. Sustained blood pressure increases could have adverse consequences in patients receiving the drug. Therefore, the manufacturer recommends that preexisting hypertension be controlled before initiating desvenlafaxine therapy and that regular blood pressure monitoring be performed in patients receiving the drug. Desvenlafaxine should be used cautiously in patients with preexisting hypertension or other underlying conditions that may be compromised by increases in blood pressure. Dosage reduction or drug discontinuance should be considered in patients who experience a sustained increase in blood pressure during therapy.

Treatment with selective serotonin-reuptake inhibitors (SSRIs) and selective serotonin and norepinephrine reuptake inhibitor (SNRIs), including desvenlafaxine, may result in hyponatremia.In many cases, hyponatremia appears to be due to the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Cases with serum sodium concentrations lower than 110 mmol/L have been reported. Geriatric individuals and patients receiving diuretics or who are otherwise volume depleted may be at greater risk of developing hyponatremia. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls; more severe and/or acute cases have been associated with hallucinations, syncope, seizures, coma, respiratory arrest, and death. Initiate appropriate medical intervention and consider drug discontinuance in patients with symptomatic hyponatremia.

5 Pharmacology and Biochemistry
5.1 Pharmacology

Desvenlafaxine is a selective serotonin and norepinephrine reuptake inhibitor. It lacks significant activity on muscarinic-cholinergic, H1-histaminergic, or α1-adrenergic receptors in vitro. Desvenlafaxine 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.


5.2 MeSH Pharmacological Classification

Serotonin and Noradrenaline Reuptake Inhibitors

Drugs that selectively block or suppress the plasma membrane transport of SEROTONIN and NORADRENALINE into axon terminals and are used as ANTIDEPRESSIVE AGENTS. (See all compounds classified as Serotonin and Noradrenaline Reuptake Inhibitors.)


Antidepressive Agents

Mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions. Several MONOAMINE OXIDASE INHIBITORS are useful as antidepressants apparently as a long-term consequence of their modulation of catecholamine levels. The tricyclic compounds useful as antidepressive agents (ANTIDEPRESSIVE AGENTS, TRICYCLIC) also appear to act through brain catecholamine systems. A third group (ANTIDEPRESSIVE AGENTS, SECOND-GENERATION) is a diverse group of drugs including some that act specifically on serotonergic systems. (See all compounds classified as Antidepressive Agents.)

5.6 Metabolism/Metabolites

Desvenlafaxine also undergoes oxidative N-demethylation via cytochrome P450 3A4 to a minor extent. CYP2D6 is not involved with the metabolism of desvenlafaxine.


Desvenlafaxine is primarily metabolized by conjugation (mediated by UGT isoforms) and, to a minor extent, through oxidative metabolism. CYP3A4 is the cytochrome P450 isozyme mediating the oxidative metabolism (N-demethylation) of desvenlafaxine. The CYP2D6 metabolic pathway is not involved, and after administration of 100 mg, the pharmacokinetics of desvenlafaxine was similar in subjects with CYP2D6 poor and extensive metabolizer phenotype. ... Approximately 19% of the administered dose is excreted as the glucuronide metabolite and < 5% as the oxidative metabolite (N,O-didesmethylvenlafaxine) in urine

5.7 Biological Half-Life

The mean terminal half life is 11.1 hours and may be prolonged in patients with renal and/or moderate to severe hepatic impairment.


The mean half life changed from approximately 10 hours in healthy subjects and subjects with mild hepatic impairment to 13 and 14 hours in moderate and severe hepatic impairment, respectively.

5.8 Mechanism of Action

Desvenlafaxine, the active metabolite of venlafaxine, is a selective serotonin and norepinephrine reuptake inhibitor. Desvenlafaxine inhibits neurotransmitter reuptake in serotonin, norepinephrine, and dopamine transporters. Desvenlafaxine 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.


The exact mechanism of antidepressant action of desvenlafaxine has not been fully elucidated but appears to be associated with the drug's potentiation of serotonergic and noradrenergic activity in the CNS. Like venlafaxine and duloxetine, desvenlafaxine is a potent inhibitor of neuronal serotonin and norepinephrine reuptake; however, inhibition of dopamine reuptake at concentrations that inhibit serotonin and norepinephrine reuptake appears unlikely in most patients. The drug does not inhibit monoamine oxidase (MAO) and has not demonstrated significant affinity for muscarinic cholinergic, H1-histaminergic, alpha1-adrenergic, dopaminergic, gamma-aminobutyric acid (GABA), glutamate, and opiate receptors in vitro.
