Why two NDCs? The FDA registers this code as 68788-8760-3 — a 5-4-1 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the package segment → 68788-8760-03. Same drug, same package — only the format differs.

📖 What it is MedlinePlus · NLM

Desvenlafaxine is used to treat depression. Desvenlafaxine is in a class of medications called selective serotonin and norepinephrine reuptake inhibitors (SNRIs). It works by increasing the amounts of serotonin and norepinephrine, natural substances in the brain that help maintain mental balance.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

Loading inactive ingredients from the official FDA label in the background. No external source is being called by this page request.

Where does this data come from?

Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?

No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.

Why might an inactive ingredient be missing?

Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.

Can inactive ingredients matter?

Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price system	Per each	Per package
Retail pharmacies payNADAC · weekly	Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo	No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · Q2 2026	$0.7941	$23.82 / 30 tablets

Where does this data come from?

NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Desvenlafaxine ER (matched by generic name) — the program that covers self-administered drugs. 1 manufacturer.

⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Desvenlafaxine ER. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?

The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.

Is the NDC printed on the package the same as the 11-digit billing NDC?

Yes, they identify this exact package in different formats. The FDA registers it as 68788-8760-3, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 68788-8760-03, written without dashes as 68788876003. The Identity section at the top of this page lists every form of this code.

What do the three segments of this NDC mean?

In 68788-8760-03, the first segment (68788) is the labeler code FDA assigned to Preferred Pharmaceuticals Inc.; the middle segment (8760) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (03) identifies this exact package size and type. Together they name one specific package of one specific product.

Is this package still being marketed?

Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Preferred Pharmaceuticals Inc.. Listing status can change — the directory data on this page refreshes weekly.

Does this product come in other package sizes?

Yes — the FDA directory lists 3 other package presentations of this same product, including 60 tablets (68788-8760-06), 90 tablets (68788-8760-09), 100 tablets (68788-8760-01). Each has its own NDC and its own page — see the package list near the top of this page.

Who lists this product with the FDA?

Preferred Pharmaceuticals Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.

Do I need a prescription for this product?

This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.

This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.

Where does this data come from?

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 [see ] . 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 [see ] . Desvenlafaxine extended-release tabletsare not approved for use in pediatric patients [see ] . WARNING: SUICIDAL THOUGHTS AND BEHAVIORS See full prescribing information for complete boxed warning. • Increased the risk of suicidal thoughts and behaviors in children, adolescents and young adults taking antidepressants ( ). • Closely monitor for clinical worsening and emergence of suicidal thoughts and behaviors ( ). • Desvenlafaxine extended-release tablets are not approved for use in pediatric patients ( ).

🎯 Indications and Usage 45 words ▾

1 INDICATIONS AND USAGE Desvenlafaxine extended-release tablets are indicated for the treatment of adults with major depressive disorder (MDD) [see ]. Desvenlafaxine Extended-Release Tablets are a serotonin and norepinephrine reuptake inhibitor (SNRI) indicated for the treatment of adults with major depressive disorder (MDD) ( ).

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION • Recommended dose: 50 mg once daily with or without food ( ). • There was no evidence that doses greater than 50 mg per day confer any additional benefit ( ). • The 25 mg per day dose is intended for a gradual reduction in dose when discontinuing treatment or dosing in severe renal and end-stage renal disease patients ( ). • Discontinuation: Reduce dose gradually whenever possible ( ). • Take tablets whole; do not divide, crush, chew, or dissolve ( ). • Moderate renal impairment: Maximum dose 50 mg per day ( ). • Severe renal impairment and end-stage renal disease: Maximum dose 25 mg per day or 50 mg every other day ( ). • Moderate to severe hepatic impairment: Maximum dose 100 mg per day ( ).

2.1General Instructions for Use The recommended dose for desvenlafaxine extended-release tablets is 50 mg once daily, with or without food. The 50 mg dose is both a starting dose and the therapeutic dose. Desvenlafaxine extended-release tablets 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.

The 25 mg per day dose is intended for a gradual reduction in dose when discontinuing treatment. When discontinuing therapy, gradual dose reduction is recommended whenever possible to minimize discontinuation symptoms [see and ].

2.2Dosage Recommendations for Patients with Renal Impairment The maximum recommended dose in patients with moderate renal impairment (24-hr creatinine clearance [ClCr] = 30 to 50 mL/min, Cockcroft-Gault [C-G]) is 50 mg per day. The maximum recommended dose in patients with severe renal impairment (ClCr 15 to 29 mL/min, C-G) or end- stage renal disease (ESRD, ClCr < 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 and ] .

2.3Dosage 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 and ] .

2.4Maintenance/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 extended-release tablets (50-400 mg) was established in two maintenance trials [see ] . Patients should be periodically reassessed to determine the need for continued treatment.

2.5Discontinuing Desvenlafaxine Extended-Release Tablets Adverse reactions may occur upon discontinuation of desvenlafaxine extended-release tablets [see ]. Gradually reduce the dosage rather than stopping desvenlafaxine extended-release tablets abruptly when discontinuing therapy with desvenlafaxine extended-release tablets. In some patients, discontinuation may need to occur over a period of several months.

2.6Switching Patients from Other Antidepressants to Desvenlafaxine Extended-Release Tablets Discontinuation symptoms have been reported when switching patients from other antidepressants, including venlafaxine, to desvenlafaxine extended-release tablets. Tapering of the initial antidepressant may be necessary to minimize discontinuation symptoms.

2.7Switching 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 extended-release tablets. Conversely, at least 7 days should be allowed after stopping desvenlafaxine extended-release tablets before s…

5.1Suicidal Thoughts and Behaviors in Pediatric and Young Adult Patients Patients with 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…

6.1Clinical 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 extended-release tablets were 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 extended-release tablets; 2,116 were exposed to desvenlafaxine extended-release tablets 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 extended-release tablets (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 extended-release tablets (4.1%) was similar to the rate for placebo (3.8%). For the 100 mg dose of desvenlafaxine extended-release tablets 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 extended-release tablets 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 extended-release tablets 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 extended-release tablets treated MDD patients and twice the rate of placebo at any dose in the pre-marketing pooled 8-week, placebo-controlled, fixed dose clinical studies.

7 DRUG INTERACTIONS

7.1Drugs Having Clinically Important Interactions with Desvenlafaxine Extended-Release Tablets Table 8: Clinically Important Drug Interactions with Desvenlafaxine Extended-Release Tablets Monoamine Oxidase Inhibitors (MAOI) Clinical Impact The concomitant use of SSRIs and SNRIs including desvenlafaxine extended-release tablets with MAOIs increases the risk of serotonin syndrome. Intervention Concomitant use of desvenlafaxine extended-release tablets is contraindicated: • With an MAOI intended to treat psychiatric disorders or within 7 days of stopping treatment with desvenlafaxine extended-release tablets. • 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 , Contraindications (4) and ].

Examples selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, methylene blue Other Serotonergic Drugs Clinical Impact Concomitant use of desvenlafaxine extended-release tablets with other serotonergic drugs increases the risk of serotonin syndrome. Intervention Monitor for symptoms of serotonin syndrome when desvenlafaxine extended-release tablets are used concomitantly with other drugs that may affect the serotonergic neurotransmitter systems. If serotonin syndrome occurs, consider discontinuation of desvenlafaxine extended-release tablets and/or concomitant serotonergic drugs [see ].

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 extended-release tablets with an antiplatelet or anticoagulant drug may potentiate the risk of bleeding. This may be due to the effect of desvenlafaxine extended-release tablets on the release of serotonin by platelets.

Intervention Closely monitor for bleeding for patients receiving an antiplatelet or anticoagulant drug when desvenlafaxine extended-release tablets are initiated or discontinued [see ] . Examples NSAIDs, aspirin, and warfarin Drugs that are Primarily Metabolized by CYP2D6 Clinical Impact Concomitant use of desvenlafaxine extended-release tablets increases Cmax and AUC of a drug primarily metabolized by CYP2D6 which may increase the risk of toxicity of the CYP2D6 substrate drug [see ] . Intervention Original dose should be taken when co-administered with desvenlafaxine extended-release tablets 100 mg or lower.

Reduce the dose of these drugs by up to one-half if co-administered with 400 mg of desvenlafaxine extended-release tablets. Examples desipramine, atomoxetine, dextromethorphan, metoprolol, nebivolol, perphenazine, tolterodine

7.2Drugs Having No Clinically Important Interactions with Desvenlafaxine Extended-Release Tablets 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 extended-release tablets [see ].

7.3Alcohol A clinical study has shown that desvenlafaxine extended-release tablets 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 extended-release tablets.

7.4Drug-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 ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS • Pregnancy: Third trimester use may result in neonatal discontinuation syndrome ( ). • Geriatric Use : There is an increased incidence of orthostatic hypotension in desvenlafaxine treated patients ≥ 65 years ( and ).

8.1Pregnancy 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 and Clinical Considerations].

There are no published studies on desvenlafaxine extended-release tablets 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 extended-release tablets, 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 2-4% and 15-20%, 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 extended-release tablets in mid to late pregnancy may increase the risk for preeclampsia, and exposure to desvenlafaxine extended-release tablets in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see ]. 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 extended-release tablets 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 unexpose…

🆘 Overdosage ~1 min read ▾

10 OVERDOSAGE

10.1Human 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 extended-release tablets) 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 extended-release tablets) 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.

10.2Management of Overdosage No specific antidotes for desvenlafaxine extended-release tablets 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.

🧬 Clinical Pharmacology ~2 min read ▾

12 CLINICAL PHARMACOLOGY

12.1Mechanism 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 SNRI.

12.2Pharmacodynamics Desvenlafaxine lacked significant affinity for numerous receptors, including muscarinic-cholinergic, H1-histaminergic, or α1-adrenergic receptors in vitro . Desvenlafaxine also lacked monoamine oxidase (MAO) inhibitory activity. ECG changes Electrocardiograms were obtained from 1,492 desvenlafaxine treated patients with major depressive disorder and 984 placebo-treated patients in clinical studies lasting up to 8 weeks.

No clinically relevant differences were observed between desvenlafaxine treated and placebo-treated patients for QT, QTc, PR, and QRS intervals. In a thorough QTc study with prospectively determined criteria, desvenlafaxine did not cause QT prolongation. No difference was observed between placebo and desvenlafaxine treatments for the QRS interval.

12.3Pharmacokinetics The single-dose pharmacokinetics of desvenlafaxine are linear and dose-proportional in a dose range of 50 to 600 mg (1 to 12 times the recommended approved dosage) per day. With once-daily dosing, steady-state plasma concentrations are achieved within approximately 4 to 5 days. At steady-state, multiple-dose accumulation of desvenlafaxine is linear and predictable from the single-dose pharmacokinetic profile.

Absorption The absolute oral bioavailability of desvenlafaxine extended-release tablets after oral administration is about 80%. Effect of Food Ingestion of a high-fat meal (800 to 1000 calories) increased desvenlafaxine Cmax about 16% and had no effect on AUC. Distribution Steady-state volume of distribution of desvenlafaxine is

3.4L/kg. Plasma protein binding of desvenlafaxine is 30% and is independent of drug concentration. Elimination Metabolism Desvenlafaxine is primarily metabolized by conjugation (mediated by UGT isoforms) and, to a minor extent, through oxidative metabolism.

CYP3A4 mediates the oxidative metabolism (N-demethylation) of desvenlafaxine. The CYP2D6 metabolic pathway is not involved. The pharmacokinetics of desvenlafaxine was similar in subjects with CYP2D6 poor and extensive metabolizer phenotype.

Excretion Approximately 45% of desvenlafaxine is excreted unchanged in urine at 72 hours after oral administration. Approximately 19% of the administered dose is excreted as the glucuronide metabolite and <5% as the oxidative metabolite (N,O-didesmethylvenlafaxine) in urine. Specific Populations No clinically significant differences in the exposures of desvenlafaxine were observed based on ethnicity (White, Black, Hispanic).

The effect of intrinsic patient factors on the pharmacokinetics of desvenlafaxine is presented in Figure 1. Figure 1 Impact of Intrinsic Factors (Renal, Hepatic Impairment and Population Description) on Desvenlafaxine Pharmacokinetics Drug Interaction Studies Clinical Studies Other Drugs on desvenlafaxine extended-release tablets The effect of ketoconazole on the exposures of desvenlafaxine is summarized in Figure 2. Figure 2.

Effect of Other Drugs on Desvenlafaxine Pharmacokinetics Desvenlafaxine extended-release tablets on Other Drugs The effects of desvenlafaxine extended-release tablets on the exposures of other drugs are summarized in Figure 3. Figure 3. Effects of desvenlafaxine extended-release tablets on Pharmacokinetics of Other Drugs In Vitro Studies Based on in vitro data, drugs that inhibit CYP isozymes 1A1, 1A2, 2A6, 2D6, 2C8, 2C9, 2C19, and 2E1 are not expected to have significant impact on the pharmacokinetic profile of desvenlafaxine.

Desvenlafaxine does not inhibit CYP1A2, 2A6, 2C8, 2C9, 2C19 CYP2D6, or CYP3A4 isozymes. Desvenlafaxine does not induce CYP3A4 either. Desvenlafaxine is not a substrate or an inhibit…
