About Trazodone

Trazodone is an atypical anti-depressant that acts as a dual serotonin agonist and serotonin reuptake inhibitor (SARI). Trazodone appears to increase serotonin activity via three mechanisms: the activation of neuronal serotonin receptors; the inhibition at the neuronal serotonin feedback system which regulates the action of serotonin; and the inhibition of the re-uptake of serotonin. Trazodone also helps to treat depression by improving sleep as a result of sedative effects caused by activation of histamine receptors and initiation and restoration of deep sleep cycles as a result of serotonin receptor activation. This may be of clinical benefit in depressed patients who have agitation, insomnia or poor sleep quality associated with their depression. Depression is one of the most prevalent central nervous system disorders, affecting at least 121 million people globally. Trazodone is widely used in its treatment with more than 14 million prescriptions written in the U.S. alone in 2006.

About Labopharm's Once-Daily Formulation of Trazodone

Insomnia and agitation may be associated with depression. In addition to its anti-depressive effects, trazodone has some sedative effects that can improve sleep. Labopharm's once-daily formulation has been specifically designed to take advantage of trazodone's unique pharmacological properties, in addition to offering the benefits of once-daily administration and potentially fewer side effects generally associated with peak concentrations of drugs.
