Name: Oleptro

Oleptro Overview

Oleptro is a prescription medication used to treat depression. Oleptro belongs to a group of drugs called serotonin modulators, which affect the natural substance, serotonin, in the brain.

This medication comes as an extended release tablet and is taken once a day in the late evening, preferably at bedtime, on an empty stomach.

Oleptro tablets should be swallowed whole or broken in half along the score line. Do not chew or crush tablets.

Common side effects of Oleptro include drowsiness, dizziness, and dry mouth.  Do not drive or operate machinery until you know how Oleptro will affect you.

Uses of Oleptro

Oleptro is a prescription medication used to treat depression. 

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Oleptro FDA Warning

Suicidality and Antidepressant Drugs

Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of Major Depressive Disorder (MDD) and other psychiatric disorders. Anyone considering the use of Oleptro or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. 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 in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Oleptro tablets are not approved for use in pediatric patients.

How should I take trazodone?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not take this medicine in larger or smaller amounts or for longer than recommended.

The trazodone immediate-release tablet should be taken after a meal or a snack.

Take Oleptro on an empty stomach at bedtime or late in the evening.

Do not crush, chew, or break an extended-release tablet. Swallow it whole. You may break an Oleptro tablet in half along the score line if needed.

It may take up to 2 weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve.

Do not stop using trazodone suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using trazodone.

Store at room temperature away from moisture, heat, and light.


Monoamine Oxidase Inhibitors (MAOIs)

The use of MAOI’s intended to treat psychiatric disorders with Oleptro or within 14 days of stopping treatment with Oleptro is contraindicated because of an increased risk of serotonin syndrome. The use of Oleptro within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated. [see DOSAGE AND ADMINISTRATION (2.3) and WARNINGS AND PRECAUTIONS (5.9)].

Starting Oleptro 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 (2.4) and WARNINGS AND PRECAUTIONS (5.2)].

Drug Interactions

Monoamine Oxidase Inhibitors (MAOIs)

[see Dosage and Administration (2.3 and 2.4), Contraindications (4.1), Warnings and Precautions (5.2 and 5.9)]

Serotonergic Drugs

[see Dosage and Administration (2.3 and 2.4), Contraindications (4.1), Warnings and Precautions (5.2 )]

Central Nervous System (CNS) Depressants

Trazodone may enhance the response to alcohol, barbiturates, and other CNS depressants.

Cytochrome P450 3A4 Inhibitors

In vitro drug metabolism studies suggest that there is a potential for drug interactions when trazodone is given with cytochrome P450 3A4 (CYP3A4) inhibitors. The effect of short-term administration of ritonavir (200 mg twice daily, 4 doses) on the pharmacokinetics of a single dose of trazodone (50 mg) has been studied in 10 healthy subjects. The Cmax of trazodone increased by 34%, the AUC increased 2.4-fold, the half-life increased by 2.2-fold, and the clearance decreased by 52%. Adverse effects including nausea, hypotension, and syncope were observed when ritonavir and trazodone were co-administered. It is likely that ketoconazole, indinavir, and other CYP3A4 inhibitors such as itraconazole may lead to substantial increases in trazodone plasma concentrations with the potential for adverse effects. If trazodone is used with a potent CYP3A4 inhibitor, the risk of cardiac arrhythmia may be increased [see Warnings and Precautions (5.5)] and a lower dose of trazodone should be considered.

Cytochrome P450 Inducers (e.g., carbamazepine)

Carbamazepine induces CYP3A4. Following co-administration of carbamazepine 400 mg per day with trazodone 100 mg to 300 mg daily, carbamazepine reduced plasma concentrations of trazodone and mchlorophenlypiperazine (an active metabolite) by 76% and 60% respectively, compared to precarbamazepine values. Patients should be closely monitored to see if there is a need for an increased dose of trazodone when taking both drugs.

Digoxin and Phenytoin

Increased serum digoxin or phenytoin levels have been reported in patients receiving trazodone concurrently with either of these drugs. Monitor serum levels and adjust dosages as needed.

NSAIDs, Aspirin, or Other Drugs Affecting Coagulation or Bleeding

Due to a possible association between serotonin modulating drugs and gastrointestinal bleeding, patients should be monitored for and cautioned about the potential risk of bleeding associated with the concomitant use of trazodone and NSAIDs, aspirin, or other drugs that affect coagulation or bleeding [see Warnings and Precautions (5.8)].


There have been reports of altered (either increased or decreased) prothrombin times in taking both warfarin and trazodone.

Oleptro - Clinical Pharmacology

Mechanism of Action

The mechanism of trazodone’s antidepressant action is not fully understood, but is thought to be related to its potentiation of serotonergic activity in the CNS.


Preclinical studies have shown that trazodone selectively inhibits neuronal reuptake of serotonin and acts as an antagonist at 5-HT-2A/2C serotonin receptors.

Trazodone is not a monoamine oxidase inhibitor and, unlike amphetamine-type drugs, does not stimulate the central nervous system.

Trazodone antagonizes alpha 1-adrenergic receptors, a property which may be associated with postural hypotension.


Steady state AUC of Trazodone is equivalent after administration of Trazodone 100 mg immediate release (IR) three (3) times a day (mean ± SD AUCss = 33058 ± 8006 ng*h/mL) and Oleptro 300 mg once daily (mean ± SD AUCss = 29131 ± 9931 ng*h/mL) for one week. Steady State Cmax and Cmin of trazodone were not equivalent after administration of trazodone 100 mg IR 3 times a day (mean ± SD Cmax,ss = 3118 ± 758 ng/mL, Cmin,ss = 843 ± 274 ng/mL) and Oleptro 300 mg once daily (mean ± SD Cmax,ss = 1812 ± 621 ng/mL, Cmin,ss = 674 ± 355 ng/mL) for one week.

Trazodone is well absorbed after oral administration, without selective localization in any tissue. Following single-dose administration of Oleptro 300 mg tablets under fasting conditions, a mean peak trazodone plasma concentration (Cmax) of 1188 ± 362 ng/mL was reported at a median Tmax of 9 hours post-dose. When Oleptro 300 mg tablets are taken shortly after ingestion of a high-fat meal, Cmax increases by about 86% compared to taking it under fasting conditions. However, AUC0-∞ and Tmax are not significantly affected by food.

Oleptro tablets are dose proportional following single-dose administration of doses ranging from 75 mg to 375 mg as intact or bisected tablets.

In vitro studies in human liver microsomes show that trazodone is metabolized, via oxidative cleavage, to an active metabolite, m-chlorophenylpiperazine (mCPP) by CYP3A4. Other metabolic pathways that may be involved in the metabolism of trazodone have not been well characterized. Trazodone is extensively metabolized; less than 1% of an oral dose is excreted unchanged in the urine.

Elimination is predominantly renal, with 70 to 75% of an oral dose being recovered in the urine within the first 72 hours of ingestion. Following single-dose administration of Oleptro 300 mg tablets, a mean apparent terminal half-life of 10 hours was reported.

Protein Binding
Trazodone is 89 to 95% protein bound in vitro at concentrations attained with therapeutic doses in humans.
