Suicidality and Antidepressant Drugs
displayName: BOXED WARNING SECTION
FDA Article Code: 34066-1
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 trazodone hydrochloride 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. Trazodone hydrochloride is not approved for use in pediatric patients.

displayName: DESCRIPTION SECTION
FDA Article Code: 34089-3
Trazodone hydrochloride is an antidepressant chemically unrelated to tricyclic, tetracyclic, or other known antidepressant agents. Trazodone hydrochloride is a triazolopyridine derivative designated as 2-[3-[4-(m-Chlorophenyl)-1-piperazinyl]propyl]s-triazolo[4,3-a]-pyridin-3(2H )-one monohydrochloride. It is a white orderless crystalline powder which is freely soluble in water. The structural formula is represented below:
C19H22ClN5O•HCl M.W. 408.32
Trazodone hydrochloride is supplied for oral administration in 50 mg or 100 mg tablets.Trazodone Hydrochloride Tablets USP 50 mg and 100 mg contain the following inactive ingredients: anhydrous lactose, colloidal silicon dioxide, crospovidone, hypromellose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate 80 and titanium dioxide.

FDA Article Code: 34090-1
The mechanism of trazodone’s antidepressant action in man is not fully understood. In animals, trazodone selectively inhibits serotonin uptake by brain synaptosomes and potentiates the behavioral changes induced by the serotonin precursor, 5-hydroxytryptophan. Cardiac conduction effects of trazodone in the anesthetized dog are qualitatively dissimilar and quantitatively less pronounced than those seen with tricyclic antidepressants. Trazodone is not a monoamine oxidase inhibitor and, unlike amphetamine-type drugs, does not stimulate the central nervous system.
INDICATIONS AND USAGE
displayName: INDICATIONS & USAGE SECTION
FDA Article Code: 34067-9
Trazodone hydrochloride is indicated for the treatment of depression. The efficacy of trazodone has been demonstrated in both inpatient and out-patient settings and for depressed patients with and without prominent anxiety. The depressive illness of patients studied corresponds to the Major Depressive Episode criteria of the American Psychiatric Association’s Diagnostic and Statistical Manual, III.aMajor Depressive Episode implies a prominent and relatively persistent (nearly every day for at least 2 weeks) depressed or dysphoric mood that usually interferes with daily functioning, and includes at least four of the following eight symptoms: change in appetite, change in sleep, psychomotor agitation or retardation, loss of interest in usual activities or decrease in sexual drive, increased fatigability, feelings of guilt or worthlessness, slowed thinking or impaired concentration, and suicidal ideation or attempts.
displayName: CONTRAINDICATIONS SECTION
FDA Article Code: 34070-3
This product is contraindicated in patients hypersensitive to trazodone.
displayName: ADVERSE REACTIONS SECTION
FDA Article Code: 34084-4
Because the frequency of adverse drug effects is affected by diverse factors (e.g., drug dose, method of detection, physician judgment, disease under treatment, etc.) a single meaningful estimate of adverse event incidence is difficult to obtain. This problem is illustrated by the variation in adverse event incidence observed and reported from the inpatients and outpatients treated with trazodone hydrochloride. It is impossible to determine precisely what accounts for the differences observed.
DOSAGE AND ADMINISTRATION
displayName: DOSAGE & ADMINISTRATION SECTION
FDA Article Code: 34068-7
The dosage should be initiated at a low level 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. Trazodone hydrochloride should be taken shortly after a meal or light snack. Symptomatic relief may be seen during the first week, with optimal antidepressant effects typically evident within 2 weeks. Twenty-five percent of those who respond to trazodone require more than 2 weeks (up to 4 weeks) of drug administration.
