Desvenlafaxine
Tablet, Extended Release · Oral
Uses
Desvenlafaxine is indicated for the treatment of adults with major depressive disorder (MDD) [see Clinical Studies (14)] . Desvenlafaxine is a serotonin and norepinephrine reuptake inhibitor (SNRI) indicated for the treatment of adults with major depressive disorder (MDD) (1).
Dosage and administration
Recommended dose: 50 mg once daily with or without food (2.1). There was no evidence that doses greater than 50 mg per day confer any additional benefit (2.1). Discontinuation: Reduce dose gradually whenever possible (2.1). Take tablets whole; do not divide, crush, chew, or dissolve (2.1). Moderate renal impairment: Maximum dose 50 mg per day (2.2). Severe renal impairment and end-stage renal disease: Maximum dose 50 mg every other day (2.2). Moderate to severe hepatic impairment: Maximum dose 100 mg per day (2.3). 2.1 General Instructions for Use The recommended dose for desvenlafaxine is 50 mg once daily, with or without food. The 50 mg dose is both a starting dose and the therapeutic dose. Desvenlafaxine should be taken at approximately the same time each day. Tablets must be swallowed whole with fluid and not divided, crushed, chewed, or dissolved. In clinical studies, doses of 10 mg to 400 mg per day were studied. In clinical studies, doses of 50 mg to 400 mg per day were shown to be effective, although no additional benefit was demonstrated at doses greater than 50 mg per day and adverse reactions and discontinuations were more frequent at higher doses. When discontinuing therapy, gradual dose reduction is recommended whenever possible to minimize discontinuation symptoms [see Dosage and Administration (2.5) and Warnings and Precautions (5.7)] . 2.2 Dosage Recommendations for Patients with Renal Impairment The maximum recommended dose in patients with moderate renal impairment (24-hr creatinine clearance [Cl Cr ] = 30 to 50 mL/min, Cockcroft-Gault [C-G]) is 50 mg per day. The maximum recommended dose in patients with severe renal impairment (Cl Cr 15 to 29 mL/min, C-G) or end-stage renal disease (ESRD, Cl Cr < 15 mL/min, C-G) is 25 mg every day or 50 mg every other day. Supplemental doses should not be given to patients after dialysis [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)]. 2.3 Dosage Recommendations for Patients with Hepatic Impairment The recommended dose in patients with moderate to severe hepatic impairment (Child-Pugh score 7 to 15) is 50 mg per day. Dose escalation above 100 mg per day is not recommended [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)]. 2.4 Maintenance/Continuation/Extended Treatment It is generally agreed that acute episodes of major depressive disorder require several months or longer of sustained pharmacologic therapy. Longer-term efficacy of desvenlafaxine (50 to 400 mg) was established in two maintenance trials [see Clinical Studies (14)] . Patients should be periodically reassessed to determine the need for continued treatment. 2.5 Discontinuing Desvenlafaxine Adverse reactions may occur upon discontinuation of desvenlafaxine [see Warnings and Precautions (5.7)]. Gradually reduce the dosage rather than stopping desvenlafaxine abruptly whenever possible. 2.6 Switching Patients From Other Antidepressants to Desvenlafaxine Discontinuation symptoms have been reported when switching patients from other antidepressants, including venlafaxine, to desvenlafaxine. Tapering of the initial antidepressant may be necessary to minimize discontinuation symptoms. 2.7 Switching Patients to or from a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders At least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with desvenlafaxine. Conversely, at least 7 days should be allowed after stopping desvenlafaxine before starting an MAOI intended to treat psychiatric disorders [see Contraindications (4)] . 2.8 Use of Desvenlafaxine with other MAOIs such as Linezolid or Methylene Blue Do not start desvenlafaxine in a patient who is being treated with linezolid or intravenous methylene blue because there is increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, other interventions, including hospitalization, should be considered [see Contraindications (4)]. In some cases, a patient already receiving desvenlafaxine therapy may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue treatment are judged to outweigh the risks of serotonin syndrome in a particular patient, desvenlafaxine should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for symptoms of serotonin syndrome for 7 days or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with desvenlafaxine may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see Warnings and Precautions (5.2)]. The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with desvenlafaxine is unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use [see Warnings and Precautions (5.2)] .

Contraindications
Hypersensitivity to desvenlafaxine succinate, venlafaxine hydrochloride or to any excipients in the desvenlafaxine extended-release tablets formulation. Angioedema has been reported in patients treated with desvenlafaxine [see Adverse Reactions (6.1)] . The use of MAOIs intended to treat psychiatric disorders with desvenlafaxine or within 7 days of stopping treatment with desvenlafaxine is contraindicated because of an increased risk of serotonin syndrome. The use of desvenlafaxine within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated [see Dosage and Administration (2.7) and Warnings and Precautions (5.2)]. Starting desvenlafaxine in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome [see Dosage and Administration (2.8) and Warnings and Precautions (5.2)]. Hypersensitivity to desvenlafaxine succinate, venlafaxine hydrochloride or any excipients in the desvenlafaxine extended-release tablets formulation (4). Serotonin Syndrome and MAOIs : Do not use MAOIs intended to treat psychiatric disorders with desvenlafaxine or within 7 days of stopping treatment with desvenlafaxine. Do not use desvenlafaxine within 14 days of stopping an MAOI intended to treat psychiatric disorders. In addition, do not start desvenlafaxine in a patient who is being treated with linezolid or intravenous methylene blue (4).
Warnings and precautions
• Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents, but also when taken alone. If it occurs, discontinue desvenlafaxine and serotonergic agents and initiate supportive treatment (5.2).
• Elevated Blood Pressure: Control hypertension before initiating treatment. Monitor blood pressure regularly during treatment (5.3).
• Increased Risk of Bleeding: Concomitant use of aspirin, NSAIDs, other antiplatelet drugs, warfarin, and other anticoagulants may increase this risk (5.4).
• Angle Closure Glaucoma: Avoid use of antidepressants, including desvenlafaxine, in patients with untreated anatomically narrow angles treated (5.5).
• Activation of Mania/Hypomania: Use cautiously in patients with Bipolar Disorder. Caution patients about risk of activation of mania/hypomania (5.6).
• Discontinuation Syndrome: Taper dose when possible and monitor for discontinuation symptoms (5.7).
• Seizure: Can occur. Use cautiously in patients with seizure disorder (5.8).
• Hyponatremia: Can occur in association with SIADH (5.9).
• Interstitial Lung Disease and Eosinophilic Pneumonia: Can occur (5.10).
• Sexual Dysfunction: Desvenlafaxine may cause symptoms of sexual dysfunction (5.11). 5.1 Suicidal Thoughts and Behaviors in Pediatric and Young Adult Patients Patients with major depressive disorder MDD, both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. Pooled analyses of short-term placebo-controlled studies of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18 to 24) with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older. The pooled analyses of placebo-controlled studies in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short-term studies of 9 antidepressant drugs in over 4,400 patients. The pooled analyses of placebo-controlled studies in adults with MDD or other psychiatric disorders included a total of 295 short-term studies (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients. There was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger patients for almost all drugs studied. There were differences in absolute risk of suicidality across the different indications, with the highest incidence in MDD. The risk differences (drug vs. placebo), however, were relatively stable within age strata and across indications. These risk differences (drug-placebo difference in the number of cases of suicidality per 1,000 patients treated) are provided in Table 1. Table 1 Age Range Drug-Placebo Difference in Number of Cases of Suicidality per 1,000 Patients Treated Increases Compared to Placebo <18 14 additional cases 18 to 24 5 additional cases Decreases Compared to Placebo 25 to 64 1 fewer case ≥65 6 fewer cases No suicides occurred in any of the pediatric studies. There were suicides in the adult studies, but the number was not sufficient to reach any conclusion about drug effect on suicide. It is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months. However, there is substantial evidence from placebo-controlled maintenance studies in adults with depression that the use of antidepressants can delay the recurrence of depression. All patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases. The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, and mania, have been reported in adult and pediatric patients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and nonpsychiatric. Although a causal link between the emergence of such symptoms and either the worsening of depression and/or the emergence of suicidal impulses has not been established, there is concern that such symptoms may represent precursors to emerging suicidality. Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patient’s presenting symptoms. If the decision has been made to discontinue treatment, medication should be tapered, as rapidly as is feasible, but with recognition that abrupt discontinuation can be associated with certain symptoms [see Dosage and Administration (2.4), Warnings and Precautions (5.7) ] .
Side effects
The following adverse reactions are discussed in greater detail in other sections of the label. Hypersensitivity [see Contraindications (4)] Suicidal Thoughts and Behaviors in Pediatric and Young Adult Patients [see Warnings and Precautions (5.1)] Serotonin Syndrome [see Warnings and Precautions (5.2)] Elevated Blood Pressure [see Warnings and Precautions (5.3)] Increased Risk of Bleeding [see Warnings and Precautions (5.4)] Angle Closure Glaucoma [see Warnings and Precautions (5.5)] Activation of Mania/Hypomania [see Warnings and Precautions (5.6)] Discontinuation Syndrome [see Warnings and Precautions (5.7)] Seizure [see Warnings and Precautions (5.8)] Hyponatremia [see Warnings and Precautions (5.9)] Interstitial Lung Disease and Eosinophilic Pneumonia [see Warnings and Precautions 5.10)] Most common adverse reactions (incidence ≥5% and twice the rate of placebo in the 50 or 100 mg dose groups) were: nausea, dizziness, insomnia, hyperhidrosis, constipation, somnolence, decreased appetite, anxiety, and specific male sexual function disorders (6.1). To report SUSPECTED ADVERSE REACTIONS, contact Alembic Pharmaceuticals Limited at 1-800-406-7984 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice. Patient exposure Desvenlafaxine was evaluated for safety in 8,394 patients diagnosed with major depressive disorder who participated in multiple-dose pre-marketing studies, representing 2,784 patient-years of exposure. Of the total 8,394 patients exposed to at least one dose of desvenlafaxine; 2,116 were exposed to desvenlafaxine for 6 months, representing 1,658 patient-years of exposure, and 421 were exposed for one year, representing 416 patient-years of exposure. Adverse reactions reported as reasons for discontinuation of treatment In the pre-marketing pooled 8-week placebo-controlled studies in patients with MDD, 1,834 patients were exposed to desvenlafaxine (50 to 400 mg).Of the 1,834 patients, 12% discontinued treatment due to an adverse reaction, compared with 3% of the 1,116 placebo-treated patients. At the recommended dose of 50 mg, the discontinuation rate due to an adverse reaction for desvenlafaxine (4.1%) was similar to the rate for placebo (3.8%). For the 100 mg dose of desvenlafaxine the discontinuation rate due to an adverse reaction was 8.7%. The most common adverse reactions leading to discontinuation in at least 2% and at a rate greater than placebo of the desvenlafaxine treated patients in the short-term studies, up to 8 weeks, were: nausea (4%); dizziness, headache and vomiting (2% each). In a longer-term study, up to 9 months, the most common was vomiting (2%). Common adverse reactions in placebo-controlled MDD studies The most commonly observed adverse reactions in desvenlafaxine treated MDD patients in pre-marketing pooled 8-week, placebo-controlled, fixed-dose studies (incidence ≥ 5% and at least twice the rate of placebo in the 50 or 100 mg dose groups) were: nausea, dizziness, insomnia, hyperhidrosis, constipation, somnolence, decreased appetite, anxiety, and specific male sexual function disorders. Table 2 shows the incidence of common adverse reactions that occurred in ≥ 2% of desvenlafaxine treated MDD patients and twice the rate of placebo at any dose in the pooled 8-week, placebo-controlled, fixed dose clinical studies.

Drug interactions
7.1 Drugs Having Clinically Important Interactions with Desvenlafaxine Table 8: Clinically Important Drug Interactions with Desvenlafaxine Monoamine Oxidase Inhibitors (MAOI) Clinical Impact The concomitant use of SSRIs and SNRIs including desvenlafaxine with MAOIs increases the risk of serotonin syndrome. Intervention Concomitant use of desvenlafaxine is contraindicated:
• With an MAOI intended to treat psychiatric disorders or within 7 days of stopping treatment with desvenlafaxine.
• Within 14 days of stopping an MAOI intended to treat psychiatric disorders.
• In a patient who is being treated with linezolid or intravenous methylene blue. [see Dosage and Administration (2.7), Contraindications (4) and Warnings and Precautions (5.2)]. Examples selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue Other Serotonergic Drugs Clinical Impact Concomitant use of desvenlafaxine with other serotonergic drugs increases the risk of serotonin syndrome. Intervention Monitor for symptoms of serotonin syndrome when desvenlafaxine is used concomitantly with other drugs that may affect the serotonergic neurotransmitter systems. If serotonin syndrome occurs, consider discontinuation of desvenlafaxine and/or concomitant serotonergic drugs [see Warnings and Precautions (5.2)]. Examples Other SNRIs, SSRIs, triptans, tricyclic antidepressants, opioids, lithium, buspirone, amphetamines, tryptophan, and St. John’s Wort Drugs that Interfere with Hemostasis Clinical Impact Concomitant use of desvenlafaxine with an antiplatelet or anticoagulant drug may potentiate the risk of bleeding. This may be due to the effect of desvenlafaxine on the release of serotonin by platelets. Intervention Closely monitor for bleeding for patients receiving an antiplatelet or anticoagulant drug when desvenlafaxine is initiated or discontinued [see Warnings and Precautions (5.4)] . Examples NSAIDs, aspirin, and warfarin Drugs that are Primarily Metabolized by CYP2D6 Clinical Impact Concomitant use of desvenlafaxine increases C max and AUC of a drug primarily metabolized by CYP2D6 which may increase the risk of toxicity of the CYP2D6 substrate drug [see Clinical Pharmacology (12.3)] . Intervention Original dose should be taken when co-administered with desvenlafaxine 100 mg or lower. Reduce the dose of these drugs by up to one-half if co-administered with 400 mg of desvenlafaxine. Examples desipramine, atomoxetine, dextromethorphan, metoprolol, nebivolol, perphenazine, tolterodine 7.2 Drugs Having No Clinically Important Interactions with Desvenlafaxine Based on pharmacokinetic studies, no dosage adjustment is required for drugs that are mainly metabolized by CYP3A4 (e.g., midazolam), or for drugs that are metabolized by both CYP2D6 and CYP3A4 (e.g., tamoxifen, aripiprazole), when administered concomitantly with desvenlafaxine [see Clinical Pharmacology (12.3)]. 7.3 Alcohol A clinical study has shown that desvenlafaxine does not increase the impairment of mental and motor skills caused by ethanol. However, as with all CNS-active drugs, patients should be advised to avoid alcohol consumption while taking desvenlafaxine. 7.4 Drug-Laboratory Test Interactions False-positive urine immunoassay screening tests for phencyclidine (PCP) and amphetamine have been reported in patients taking desvenlafaxine. This is due to lack of specificity of the screening tests. False positive test results may be expected for several days following discontinuation of desvenlafaxine therapy. Confirmatory tests, such as gas chromatography/mass spectrometry, will distinguish desvenlafaxine from PCP and amphetamine.
Use in specific populations
Pregnancy: Third trimester use may result in neonatal discontinuation syndrome (8.1). Geriatric Use: There is an increased incidence of orthostatic hypotension in desvenlafaxine treated patients ≥ 65 years (6.1 and 8.5). 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185. Risk summary Based on data from published observational studies, exposure to SNRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see Warnings and Precautions (5.4) and Clinical Considerations]. There are no published studies on desvenlafaxine in pregnant women; however published epidemiologic studies of pregnant women exposed to venlafaxine, the parent compound, have not reported a clear association with adverse developmental outcomes (see Data) . There are risks associated with untreated depression in pregnancy and with exposure to SNRIs and SSRIs, including desvenlafaxine, during pregnancy ( see Clinical Considerations). In reproductive developmental studies in rats and rabbits treated with desvenlafaxine succinate, there was no evidence of teratogenicity at a plasma exposure (AUC) that is up to 19-times (rats) and 0.5-times (rabbits) the exposure at an adult human dose of 100 mg per day. However, fetotoxicity and pup deaths were observed in rats at 4.5-times the AUC exposure observed with an adult human dose of 100 mg per day. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk A prospective longitudinal study of 201 women with a history of major depression who were euthymic at the beginning of pregnancy, showed that women who discontinued antidepressant medication during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressant medication. Maternal adverse reactions Exposure to desvenlafaxine in mid to late pregnancy may increase the risk for preeclampsia, and exposure to desvenlafaxine in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see Warnings and Precautions (5.4)]. Fetal/Neonatal adverse reactions Exposure to SNRIs or SSRIs in late pregnancy may lead to an increased risk for neonatal complications requiring prolonged hospitalization, respiratory support, and tube feeding. Monitor neonates who were exposed to desvenlafaxine in the third trimester of pregnancy for drug discontinuation syndrome (see Data). Data Human Data Published epidemiological studies of pregnant women exposed to the parent compound venlafaxine have not reported a clear association with major birth defects or miscarriage. Methodological limitations of these observational studies include possible exposure and outcome misclassification, lack of adequate controls, adjustment for confounders, and confirmatory studies; therefore, these studies cannot establish or exclude any drug-associated risk during pregnancy. Retrospective cohort studies based on claims data have shown an association between venlafaxine use and preeclampsia, compared to depressed women who did not take an antidepressant during pregnancy. One study that assessed venlafaxine exposure in the second trimester or first half of the third trimester and preeclampsia showed an increased risk compared to unexposed depressed women (adjusted (adj) RR 1.57, 95% CI 1.29 to 1.91). Preeclampsia was observed at venlafaxine doses equal to or greater than 75 mg/day and a duration of treatment >30 days. Another study that assessed venlafaxine exposure in gestational weeks 10 to 20 and preeclampsia showed an increased risk at doses equal to or greater than 150 mg/day. Available data are limited by possible outcome misclassification and possible confounding due to depression severity and other confounders. Retrospective cohort studies based on claims data have suggested an association between venlafaxine use near the time of delivery or through delivery and postpartum hemorrhage. One study showed an increased risk for postpartum hemorrhage when venlafaxine exposure occurred through delivery, compared to unexposed depressed women (adj RR 2.24, 95% CI 1.69 to 2.97). There was no increased risk in women who were exposed to venlafaxine earlier in pregnancy. Limitations of this study include possible confounding due to depression severity and other confounders. Another study showed an increased risk for postpartum hemorrhage when SNRI exposure occurred for at least 15 days in the last month of pregnancy or through delivery, compared to unexposed women (adj RR 1.64 to 1.76). The results of this study may be confounded by the effects of depression. Neonates exposed to SNRIs or SSRIs, late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These features are consistent with either a direct toxic effect of SSRIs and SNRIs or, possibly, a drug discontinuation syndrome.

It should be noted that, in some cases, the clinical picture is consistent with serotonin syndrome [see Warnings and Precautions (5.2)] .

8.4 Pediatric Use The safety and effectiveness of desvenlafaxine have not been established in pediatric patients for the treatment of MDD. Antidepressants, such as desvenlafaxine, increase the risk of suicidal thoughts and behaviors in pediatric patients [see the Boxed Warning and Warnings and Precautions (5.1)] . Additional information describing clinical studies in which efficacy was not demonstrated in pediatric patients is approved for Wyeth Pharmaceuticals Inc. a subsidiary of Pfizer Inc.’s PRISTIQ® (desvenlafaxine) Extended-Release Tablets. However, due to Wyeth Pharmaceuticals Inc., a subsidiary of Pfizer Inc.’s marketing exclusivity rights, this product is not labeled with that pediatric information. Juvenile Animal Studies In a juvenile animal study, male and female rats were treated with desvenlafaxine (75, 225 and 675 mg/kg/day) starting on postnatal day (PND) 22 through 112. Behavioral deficits (longer time immobile in a motor activity test, longer time swimming in a straight channel test, and lack of habituation in an acoustic startle test) were observed in males and females but were reversed after a recovery period. A No Adverse Effect Level (NOAEL) was not identified for these deficits. The Low Adverse Effect Level (LOAEL) was 75 mg/kg/day which was associated with plasma exposure (AUC) twice the levels measured with a pediatric dose of 100 mg/day. In a second juvenile animal study, male and female rats were administered desvenlafaxine (75, 225 or 675 mg/kg/day) for 8 to 9 weeks starting on PND 22 and were mated with naïve counterparts. Delays in sexual maturation and decreased fertility, number of implantation sites and total live embryos were observed in treated females at all doses. The LOAEL for these findings is 75 mg/kg/day which was associated with an AUC twice the levels measured with a pediatric dose of 100 mg/day. These findings were reversed at the end of a 4-week recovery period. The relevance of these findings to humans is not known.
Geriatric use
8.5 Geriatric Use Of the 4,158 patients in pre-marketing clinical studies with desvenlafaxine, 6% were 65 years of age or older. No overall differences in safety or efficacy were observed between these patients and younger patients; however, in the short-term placebo-controlled studies, there was a higher incidence of systolic orthostatic hypotension in patients ≥65 years of age compared to patients <65 years of age treated with desvenlafaxine [see Adverse Reactions (6.1)] . For elderly patients, possible reduced renal clearance of desvenlafaxine should be considered when determining dose [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)] . SSRIs and SNRIs, including desvenlafaxine, have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse event [see Warnings and Precautions (5.9)] .
Overdosage
10.1 Human Experience with Overdosage There is limited clinical trial experience with desvenlafaxine succinate overdosage in humans. However, desvenlafaxine is the major active metabolite of venlafaxine. Overdose experience reported with venlafaxine (the parent drug of desvenlafaxine) is presented below; the identical information can be found in the Overdosage section of the venlafaxine package insert. In postmarketing experience, overdose with venlafaxine (the parent drug of desvenlafaxine) has occurred predominantly in combination with alcohol and/or other drugs. The most commonly reported events in overdosage include tachycardia, changes in level of consciousness (ranging from somnolence to coma), mydriasis, seizures, and vomiting. Electrocardiogram changes (e.g., prolongation of QT interval, bundle branch block, QRS prolongation), sinus and ventricular tachycardia, bradycardia, hypotension, rhabdomyolysis, vertigo, liver necrosis, serotonin syndrome, and death have been reported. Published retrospective studies report that venlafaxine overdosage may be associated with an increased risk of fatal outcomes compared to that observed with SSRI antidepressant products, but lower than that for tricyclic antidepressants. Epidemiological studies have shown that venlafaxine-treated patients have a higher pre-existing burden of suicide risk factors than SSRI-treated patients. The extent to which the finding of an increased risk of fatal outcomes can be attributed to the toxicity of venlafaxine in overdosage, as opposed to some characteristic(s) of venlafaxine-treated patients, is not clear. 10.2 Management of Overdosage No specific antidotes for desvenlafaxine are known. In managing over dosage, consider the possibility of multiple drug involvement. In case of overdose, call Poison Control Center at 1-800-222-1222 for latest recommendations.
Description
Desvenlafaxine extended-release tablets for oral administration contains desvenlafaxine, USP, a structurally novel SNRI for the treatment of MDD. Desvenlafaxine (O-desmethylvenlafaxine), USP is the major active metabolite of the antidepressant venlafaxine, a medication used to treat major depressive disorder. Desvenlafaxine, USP is designated RS -4-[2-dimethylamino-1-(1-hydroxycyclohexyl)ethyl]phenol and has the empirical formula of C 16 H 25 NO 2 . Desvenlafaxine, USP has a molecular weight of 263.38. The structural formula is shown below. * Chiral Centre Desvenlafaxine, USP is a white to off-white crystalline powder that is sparingly soluble in dimethyl sulfoxide. The solubility of desvenlafaxine is pH dependent. Desvenlafaxine, USP is formulated as an extended-release tablet for once-a-day oral administration. Each 50 mg or 100 mg extended-release tablet contains 50 or 100 mg of desvenlafaxine, USP, respectively. Inactive ingredients for the 50 mg tablet consist of alginic acid, citric acid monohydrate powder, hypromellose, microcrystalline cellulose, povidone, talc, magnesium stearate and film coating, which consist of hypromellose, titanium dioxide, polyethylene glycol, talc, and iron oxide red. Inactive ingredients for the 100 mg tablet consist of alginic acid, citric acid monohydrate powder, hypromellose, microcrystalline cellulose, povidone, talc, magnesium stearate and film coating, which consist of hypromellose, titanium dioxide, polyethylene glycol, iron oxide red, and iron oxide black. Structure
Mechanism of action
12.1 Mechanism of Action The exact mechanism of the antidepressant action of desvenlafaxine is unknown, but is thought to be related to the potentiation of serotonin and norepinephrine in the central nervous system, through inhibition of their reuptake. Non-clinical studies have shown that desvenlafaxine is a potent and selective serotonin and norepinephrine reuptake inhibitor (SNRI).
