Trazodone and Its Augmentation With Pregabalin in the Treatment of Fibromyalgia - Full Text View

Sponsor:	Universidad de Granada
Information provided by:	Universidad de Granada
ClinicalTrials.gov Identifier:	NCT00791739

Purpose

The study has a double purpose: a first phase intends to assess the effectiveness and tolerability of trazodone, an antidepressant with sedative and sleep-promoting properties, in the treatment of fibromyalgia; a second phase intends to evaluate if the addition of pregabalin to patients who have shown a partial response to trazodone additionally improves fibromyalgia symptomatology.

Condition	Intervention	Phase
