Trazodone hydrochloride tablets are indicated for the treatment of major depressive disorder (MDD) in adults. Trazodone hydrochloride tablets are a selective serotonin reuptake inhibitor indicated for the treatment of major depressive disorder (MDD) (1).
Starting dose: 150 mg in divided doses daily. May be increased by 50 mg per day every three to four days. Maximum dose: 400 mg per day in divided doses (2). Trazodone hydrochloride tablets should be taken shortly after a meal or light snack (2). Tablets should be swallowed whole or broken in half along the score line, and should not be chewed or crushed (2). When discontinued, gradual dose reduction is recommended (2).
An initial dose of 150 mg/day in divided doses is suggested. The dosage should be initiated at a low-dose and increased gradually, noting the clinical response and any evidence of intolerance. Occurrence of drowsiness may require the administration of a major portion of the daily dose at bedtime or a reduction of dosage. The dose may be increased by 50 mg/day every 3 to 4 days. The maximum dose for outpatients usually should not exceed 400 mg/day in divided doses. Inpatients (i.e., more severely depressed patients) may be given up to but not in excess of 600 mg/day in divided doses. Once an adequate response has been achieved, dosage may be gradually reduced, with subsequent adjustment depending on therapeutic response.
Trazodone hydrochloride tablets can be swallowed whole or administered as a half tablet by breaking the tablet along the score line. Trazodone hydrochloride tablets should be taken shortly after a meal or light snack.
Prior to initiating treatment with trazodone hydrochloride tablets or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.7)].
At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of trazodone hydrochloride tablets. In addition, at least 14 days must elapse after stopping trazodone hydrochloride tablets before starting an MAOI antidepressant [see Contraindications (4), Warnings and Precautions (5.2)].
Coadministration with Strong CYP3A4 Inhibitors Consider reducing trazodone hydrochloride tablets dose based on tolerability when trazodone hydrochloride tablets are coadministered with a strong CYP3A4 inhibitor [see Drug Interactions (7.1)]. Coadministration with Strong CYP3A4 Inducers Consider increasing trazodone hydrochloride tablets dose based on therapeutic response when trazodone hydrochloride tablets are coadministered with a strong CYP3A4 inducer [see Drug Interactions (7.1)].
Adverse reactions may occur upon discontinuation of trazodone hydrochloride tablets [See Warnings and Precautions (5.8)]. Gradually reduce the dosage rather than stopping trazodone hydrochloride tablets abruptly whenever possible.
Trazodone hydrochloride tablets, USP are available in the following strengths: 50 mg: White, round, compressed tablet, debossed PLIVA 433 on one side and scored on the other side. 100 mg: White, round, compressed tablet, debossed PLIVA 434 on one side and scored on the other side. 150 mg: White, oval, flat-faced, beveled edge tablet, scored and debossed as PLIVA bisect 441 on one side and tri-scored and debossed as 50 in each section on the other side. Bisectable tablets of 50 mg, 100 mg and 150 mg (3).
Trazodone hydrochloride tablets are contraindicated in: Patients taking, or within 14 days of stopping, monoamine oxidase inhibitors (MAOIs), including MAOIs such as linezolid or intravenous methylene blue, because of an increased risk of serotonin syndrome [see Warnings and Precautions (5.2), Drug Interactions (7.1)]. Concomitant use of monoamine oxidase inhibitors (MAOIs), or use within 14 days of stopping MAOIs (4).
Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents (e.g., SSRI, SNRI, triptans), but also when taken alone. If it occurs, discontinue trazodone hydrochloride tablets and initiate supportive treatment (5.2). Cardiac Arrhythmias: Increases the QT interval. Avoid use with drugs that also increase the QT interval and in patients with risk factors for prolonged QT interval (5.3) Orthostatic Hypotension and Syncope: Warn patients of risk and symptoms of hypotension (5.4). Increased Risk of Bleeding: Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), other antiplatelet drugs, warfarin, and other anticoagulants may increase this risk (5.5). Priapism: Cases of painful and prolonged penile erections and priapism have been reported. Immediate medical attention should be sought if signs and symptoms of prolonged penile erections or priapism are observed (5.6). Activation of Mania or Hypomania: Screen for bipolar disorder and monitor for mania or hypomania (5.7). Potential for Cognitive and Motor Impairment: Has potential to impair judgment, thinking, and motor skills. Advise patients to use caution when operating machinery (5.9). Angle-Closure Glaucoma: Avoid use of antidepressants, including trazodone hydrochloride tablets, in patients with untreated anatomically narrow angles. (5.10).
In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and over 4,400 pediatric patients, the incidence of suicidal thoughts and behaviors in pediatric and young adult patients was greater in antidepressant-treated patients than in placebo-treated patients. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1000 patients treated are provided in Table 1. 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 antidepressant drug effect on suicide. Table 1: Risk Differences of the Number of Cases of Suicidal Thoughts or Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients Age Range (years) Drug-Placebo Difference in Number of Patients of Suicidal Thoughts or Behaviors per 1000 Patients Treated Increases Compared to Placebo < 18 14 additional patients 18 to 24 5 additional patients Decreases Compared to Placebo 25 to 64 1 fewer patient 65 6 fewer patients It is unknown whether the risk of suicidal thoughts and behaviors in pediatric and young adult patients extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression. Monitor all antidepressant-treated patients for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing trazodone hydrochloride tablets, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.
Serotonin-norepinephrine reuptake inhibitors (SNRIs) and SSRIs, including trazodone hydrochloride tablets, can precipitate serotonin syndrome, a potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John s Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Contraindications (4), Drug Interactions (7.1)]. Serotonin syndrome can also occur when these drugs are used alone. Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). The concomitant use of trazodone hydrochloride tablets with MAOIs is contraindicated. In addition, do not initiate trazodone hydrochloride tablets in a patient being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking trazodone hydrochloride tablets, discontinue trazodone hydrochloride tablets before initiating treatment with the MAOI [see Contraindications (4), Drug Interactions (7.1)]. Monitor all patients taking trazodone hydrochloride tablets for the emergence of serotonin syndrome. Discontinue treatment with trazodone hydrochloride tablets and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of trazodone hydrochloride tablets with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.
Clinical studies indicate that trazodone hydrochloride may be arrhythmogenic in patients with preexisting cardiac disease. Arrhythmias identified include isolated PVCs, ventricular couplets, tachycardia with syncope, and torsade de pointes. Postmarketing events, including torsade de pointes have been reported at doses of 100 mg or less with the immediate-release form of trazodone hydrochloride. Trazodone hydrochloride should also be avoided in patients with a history of cardiac arrhythmias, as well as other circumstances that may increase the risk of the occurrence of torsade de pointes and/or sudden death, including symptomatic bradycardia, hypokalemia or hypomagnesemia, and the presence of congenital prolongation of the QT interval. Trazodone hydrochloride is not recommended for use during the initial recovery phase of myocardial infarction. Caution should be used when administering trazodone hydrochloride to patients with cardiac disease and such patients should be closely monitored, since antidepressant drugs (including trazodone hydrochloride ) may cause cardiac arrhythmias [see Adverse Reactions (6.2)]. Trazodone hydrochloride prolongs the QT/QTc interval. The use of trazodone hydrochloride should be avoided in patients with known QT prolongation or in combination with other drugs that are inhibitors of CYP3A4 (e.g., itraconazole, clarithromycin, voriconazole), or known to prolong QT interval including Class 1A antiarrhythmics (e.g., quinidine, procainamide) or Class 3 antiarrhythmics (e.g., amiodarone, sotalol), certain antipsychotic medications (e.g., ziprasidone, chlorpromazine, thioridazine), and certain antibiotics (e.g., gatifloxacin). Concomitant administration of drugs may increase the risk of cardiac arrhythmia [see Drug Interactions (7.1)].
Hypotension, including orthostatic hypotension and syncope has been reported in patients receiving trazodone hydrochloride. Concomitant use with an antihypertensive may require a reduction in the dose of the antihypertensive drug.
Drugs that interfere with serotonin reuptake inhibition, including trazodone hydrochloride, increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDS), other antiplatelet drugs, warfarin, and other anticoagulants may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Bleeding events related to drugs that interfere with serotonin reuptake have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages. Inform patients about the risk of bleeding associated with the concomitant use of trazodone hydrochloride and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor coagulation indices when initiating, titrating, or discontinuing trazodone hydrochloride.
Cases of priapism (painful erections greater than 6 hours in duration) have been reported in men receiving trazodone hydrochloride tablets. Priapism, if not treated promptly, can result in irreversible damage to the erectile tissue. Men who have an erection lasting greater than 4 hours, whether painful or not, should immediately discontinue the drug and seek emergency medical attention [see Adverse Reactions (6.2), Overdosage (10)]. Trazodone hydrochloride tablets should be used with caution in men who have conditions that might predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, or leukemia), or in men with anatomical deformation of the penis (e.g., angulation, cavernosal fibrosis, or Peyronie s disease).
In patients with bipolar disorder, treating a depressive episode with trazodone hydrochloride tablets or another antidepressant may precipitate a mixed/manic episode. Activation of mania/hypomania has been reported in a small proportion of patients with major affective disorder who were treated with antidepressants. Prior to initiating treatment with trazodone hydrochloride tablets, screen patients for any personal or family history of bipolar disorder, mania, or hypomania [see Dosage and Administration (2.3)].
Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation, include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible [See Dosage and Administration (2.6)].
Trazodone hydrochloride tablets may cause somnolence or sedation and may impair the mental and/or physical ability required for the performance of potentially hazardous tasks. Patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that the drug treatment does not affect them adversely.
The pupillary dilation that occurs following use of many antidepressant drugs including trazodone hydrochloride tablets may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. Avoid use of antidepressants, including trazodone hydrochloride tablets, in patients with untreated anatomically narrow angles.
Hyponatremia may occur as a result of treatment with SNRIs and SSRIs, including trazodone hydrochloride tablets. Cases with serum sodium lower than 110 mmol/L have been reported. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which can lead to falls. Signs and symptoms associated with more severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). In patients with symptomatic hyponatremia, discontinue trazodone hydrochloride tablets and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia with SSRIs and SNRIs [see Use in Specific Populations (8.5)].
The following serious adverse reactions are described elsewhere in the labeling: Suicidal Thoughts and Behavior in Children, Adolescents and Young Adults [see Boxed Warning and Warnings and Precautions (5.1)] Serotonin Syndrome [see Warnings and Precautions (5.2)] Cardiac Arrythmias (see Warnings and Precautions (5.3)] Orthostatic Hypotension and Syncope [see Warnings and Precautions (5.4)] Increased Risk of Bleeding [see Warnings and Precautions (5.5)] Priapism [see Warnings and Precautions (5.6)] Activation of Mania or Hypomania [see Warnings and Precautions (5.7)] Discontinuation Syndrome [see Warnings and Precautions (5.8)] Potential for Cognitive and Motor Impairment [see Warnings and Precautions (5. 9 )] Angle-Closure Glaucoma [see Warnings and Precautions (5.10)] Hyponatremia [see Warnings and Precautions (5.11)] Most common adverse reactions (incidence 5% and twice that of placebo) are: edema, blurred vision, syncope, drowsiness, fatigue, diarrhea, nasal congestion, weight loss (6). To report SUSPECTED ADVERSE REACTIONS, contact Teva at 1-888-838-2872 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
Trazodone has not been studied in patients with hepatic impairment. Trazodone should be used with caution in this population.
CNS Depressants: Trazodone hydrochloride tablets may enhance effects of alcohol, barbiturates, or other CNS depressants (7). CYP3A4 Inhibitors: Consider trazodone hydrochloride tablets dose reduction based on tolerability (2.5, 7). CYP3A4 Inducers: Increase in trazodone hydrochloride tablets dosage may be necessary (2.5, 7). Digoxin or Phenytoin: Monitor for increased digoxin or phenytoin serum levels (7). Warfarin: Monitor for increased or decreased prothrombin time (7).
Table 3: Clinically Important Drug Interactions with Trazodone Hydrochloride Tablets Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact: The concomitant use of MAOIs and serotonergic drugs including trazodone hydrochloride tablets increases the risk of serotonin syndrome. Intervention: Trazodone hydrochloride tablets are contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Contraindications (4), Dosage and Administration (2.3, 2.4), and Warnings and Precautions (5.2)]. Examples: isocarboxazid, moclobemide, phenelzine, selegiline, tranylcypromine Other Serotonergic Drugs Clinical Impact: The concomitant use of serotonergic drugs including trazodone hydrochloride tablets and other serotonergic drugs increases the risk of serotonin syndrome. Intervention: Monitor patients for signs and symptoms of serotonin syndrome, particularly during trazodone hydrochloride tablets initiation. If serotonin syndrome occurs, consider discontinuation of trazodone hydrochloride tablets and/or concomitant serotonergic drugs [see Warnings and Precautions (5.2)]. Examples: triptans, antidepressants (tricyclic and serotonin uptake inhibitors), fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John's Wort Antiplatelet Agents and Anticoagulants Clinical Impact: Serotonin release by platelets plays an important role in hemostasis. The concurrent use of an antiplatelet agent or anticoagulant with trazodone hydrochloride tablets may potentiate the risk of bleeding. Intervention: Inform patients of the increased risk of bleeding with the concomitant use of trazodone hydrochloride tablets and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio (INR) when initiating or discontinuing trazodone hydrochloride tablets [see Warnings and Precautions (5.5)]. Examples: warfarin, rivaroxaban, dabigatran, clopidogrel Strong CYP3A4 Inhibitors Clinical Impact: The concomitant use of trazodone hydrochloride tablets and strong CYP3A4 inhibitors increased the exposure of trazodone compared to the use of trazodone hydrochloride tablets alone. Intervention: If trazodone hydrochloride tablets is used with a potent CYP3A4 inhibitor, the risk of adverse reactions, including cardiac arrhythmias, may be increased and a lower dose of trazodone hydrochloride tablets should be considered [see Dosage and Administration (2.5), Warnings and Precautions (5.3)]. Examples: itraconazole, ketoconazole, clarithromycin, indinavir Strong CYP3A4 Inducers Clinical Impact: The concomitant use of trazodone hydrochloride tablets and strong CYP3A4 inducers decreased the exposure of trazodone compared to the use of trazodone hydrochloride tablets alone. Intervention: Patients should be closely monitored to see if there is a need for an increased dose of trazodone hydrochloride tablets when taking CYP3A4 inducers [see Dosage and Administration (2.5)]. Examples: rifampin, carbamazepine, phenytoin, St. John s wort Digoxin and Phenytoin Clinical Impact: Digoxin and phenytoin are narrow therapeutic index drugs. Concomitant use of trazodone hydrochloride tablets can increase digoxin or phenytoin concentrations. Intervention: Measure serum digoxin or phenytoin concentrations before initiating concomitant use of trazodone hydrochloride tablets. Continue monitoring and reduce digoxin or phenytoin dose as necessary. Examples: digoxin, phenytoin Central Nervous System (CNS) Depressants Clinical Impact: Trazodone hydrochloride tablets may enhance the response CNS depressants. Intervention: Patients should be counseled that trazodone hydrochloride tablets may enhance the response to alcohol, barbiturates, and other CNS depressants. Examples: alcohol, barbiturates QT Interval Prolongation Clinical Impact: Concomitant use of drugs that prolong the QT interval may add to the QT effects of trazodone hydrochloride tablets and increase the risk of cardiac arrhythmia. Intervention: Avoid the use of trazodone hydrochloride tablets in combination with other drugs known to prolong QTc [see Warnings and Precautions (5.3)]. Examples: Class 1A antiarrhythmics: quinidine, procainamide, disopyramide; Class 3 antiarrhythmics: amiodarone, sotalol; Antipsychotics: ziprasidone, chlorpromazine, thioridazine; Antibiotics: gatifloxacin
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 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/ Risk Summary Published prospective cohort studies, case series, and case reports over several decades with trazodone hydrochloride use in pregnant women have not identified any drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data). Trazodone hydrochloride has been shown to cause increased fetal resorption and other adverse effects on the fetus in the rat when given at dose levels approximately 7.3 to 11 times the maximum recommended human dose (MRHD) of 400 mg/day in adults on a mg/m2 basis. There was also an increase in congenital anomalies in the rabbit at approximately 7.3 to 22 times the MRHD on a mg/m2 basis (see Data). 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 embryofetal risk A prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. The women who discontinued antidepressants during pregnancy were more likely to experience a relapse of major depression that women who continued antidepressants. Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. Data Human Data While available studies cannot definitively establish the absence of risk, published data from prospective cohort studies, case series, and case reports over several decades have not identified an association with trazodone use during pregnancy and major birth defects, miscarriage, or other adverse maternal or fetal outcomes. All available studies have methodological limitations, including small sample size and inconsistent comparator groups. Animal Data No teratogenic effects were observed when trazodone was given to pregnant rats and rabbits during the period of organogenesis at oral doses up to 450 mg/kg/day. This dose is 11 and 22 times, in rats and rabbits, respectively, the maximum recommended human dose (MRHD) of 400 mg/day in adults on a mg/m2 basis. Increased fetal resorption and other adverse effects on the fetus in rats at 7.3 to 11 times the MRHD and increase in congenital anomalies in rabbits at 7.3 to 22 times the MRHD on a mg/m2 basis were observed. No further details on these studies are available.
Risk Summary Data from published literature report the transfer of trazodone into human milk. There are no data on the effect of trazodone on milk production. Limited data from postmarketing reports have not identified and association of adverse effects on the breastfed child. The developmental and health benefits of breastfeeding should be considered along with the mother s clinical need for trazodone hydrochloride and any potential adverse effects on the breastfed child from trazodone hydrochloride or from the underlying maternal condition.
Safety and effectiveness in the pediatric population have not been established. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning, Warnings and Precautions (5.1)].
Reported clinical literature and experience with trazodone has not identified differences in responses between elderly and younger patients. However, as experience in the elderly with trazodone hydrochloride is limited, it should be used with caution in geriatric patients. Serotonergic antidepressants have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse reaction [see Warnings and Precautions (5.11)].
Trazodone hydrochloride tablets are not a controlled substance.
Although trazodone hydrochloride has not been systematically studied in preclinical or clinical studies for its potential for abuse, no indication of drug-seeking behavior was seen in the clinical studies with trazodone hydrochloride.
Death from overdose has occurred in patients ingesting trazodone hydrochloride and other CNS depressant drugs concurrently (alcohol; alcohol and chloral hydrate and diazepam; amobarbital; chlordiazepoxide; or meprobamate). The most severe reactions reported to have occurred with overdose of trazodone hydrochloride alone have been priapism, respiratory arrest, seizures, and ECG changes, including QT prolongation. The reactions reported most frequently have been drowsiness and vomiting. Overdosage may cause an increase in incidence or severity of any of the reported adverse reactions. There is no specific antidote for trazodone hydrochloride overdose. In managing overdosage, consider the possibility of multiple drug involvement. For current information on the management of poisoning or overdose, contact a poison control center (1-800-222-1222 or www.poison.org).
Trazodone hydrochloride tablets, USP for oral administration contain trazodone hydrochloride, USP a selective serotonin reuptake inhibitor and 5HT2 receptor antagonist. Trazodone hydrochloride, USP is a triazolopyridine derivative designated as 2-[3-[4-(3-chlorophenyl)-1-piperazinyl]propyl]-1,2,4-triazolo[4, 3-a]pyridin-3(2H)-one hydrochloride. It is a white, odorless crystalline powder which is freely soluble in water. The structural formula is represented as follows: C19H22CIN5O HCl M.W. 408.32 Each tablet, for oral administration, contains 50 mg, 100 mg or 150 mg of trazodone hydrochloride, USP. In addition, each tablet contains colloidal silicon dioxide, lactose anhydrous, magnesium stearate, microcrystalline cellulose and sodium starch glycolate.
The mechanism of trazodone s antidepressant action is not fully understood, but is thought to be related to its enhancement of serotonergic activity in the CNS. Trazodone is both a selective serotonin reuptake inhibitor (SSRI) and a 5HT2 receptor antagonist and the net result of this action on serotonergic transmission and its role in trazodone s antidepressant effect is unknown.
Preclinical studies have shown that trazodone selectively inhibits neuronal reuptake of serotonin (Ki = 367 nM) and acts as an antagonist at 5-HT-2A (Ki = 35.6 nM) serotonin receptors. Trazodone is also an antagonist at several other monoaminergic receptors including 5-HT2B (Ki = 78.4 nM), 5-HT2C (Ki = 224 nM), 1A (Ki = 153 nM), 2C (Ki = 155 nM) receptors and it is a partial agonist at 5- HT1A (Ki = 118 nM) receptor. Trazodone antagonizes alpha 1-adrenergic receptors, a property which may be associated with postural hypotension.
Absorption In humans, trazodone hydrochloride is absorbed after oral administration without selective localization in any tissue. When trazodone hydrochloride is taken shortly after ingestion of food, there may be an increase in the amount of drug absorbed, a decrease in maximum concentration and a lengthening in the time to maximum concentration. Peak plasma levels occur approximately one hour after dosing when trazodone hydrochloride is taken on an empty stomach or 2 hours after dosing when taken with food. Metabolism 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 In some patients trazodone may accumulate in the plasma. Protein Binding Trazodone is 89 to 95% protein bound in vitro at concentrations attained with therapeutic doses in humans.
Carcinogenesis No drug- or dose-related occurrence of carcinogenesis was evident in rats receiving trazodone in daily oral doses up to 7.3 times the maximum recommended human dose (MRHD) of 400 mg/day in adults on a mg/m2 basis. Mutagenesis No genotoxicity studies were conducted with trazodone. Impairment of Fertility Trazodone has no effect on fertility in rats at doses up to 7.3 times the MRHD in adults on a mg/m2 basis.
The efficacy and safety of trazodone hydrochloride were established from inpatient and outpatient trials of the trazodone immediate release formulation in the treatment of major depressive disorder.
