About OLEPTRO(TM)

OLEPTRO(TM) (trazodone hydrochloride) Extended Release Tablets is a novel once-daily formulation of the antidepressant trazodone for the treatment of major depressive disorder (MDD) in adults.

OLEPTRO(TM) is an extended release formulation of trazodone hydrochloride, and uses CONTRAMID(R), Labopharm's clinically validated technology to control the release of active substances within oral medications, whether taken whole or scored. CONTRAMID(R), in its dry state, acts as a free-flowing, highly compressible powder. When in tablet form and wetted, it forms a long-lasting, uniform surface membrane that is ideally suited to controlled release of orally administered drugs under a broad range of in-body conditions.

Important Safety Information

Antidepressants can increase suicidal thoughts and behaviors in children, adolescents, and young adults. Suicide is a known risk of depression and some other psychiatric disorders. Patients should call their doctor right away if they experience new or worsening depression symptoms, unusual changes in behavior, or thoughts of suicide. Be especially observant within the first few months of treatment or after a change in dose. OLEPTRO(TM) is not approved for use in pediatric patients.

Warning and Precautions

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, or unusual change in behavior, whether or not they are taking antidepressant medications.

Patients should be monitored for clinical worsening and suicidality and for the appearance of any of the following symptoms: anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, and mania. Families and caregivers should be alerted about the need to monitor patients.

The development of a potentially life-threatening serotonin syndrome, or neuroleptic malignant syndrome (NMS)-like reactions has been reported with antidepressants, and may occur with OLEPTRO(TM), particularly with concomitant use of other serotoninergic drugs.
