About

This study aims at evaluating the efficacy and safety of methylphenidate in the initial treatment of acute mania in patients with bipolar affective disorders.

Full description

Mania can be regarded as an autoregulatory mechanism to enhance unstable vigilance. There is increasing evidence that psychostimulants that increase vigilance may be effective in treating mania. However, controlled studies are lacking.

This is a two-arm, randomised, placebo-controlled, double-blind, parallel, multi-centre phase IIIb exploratory study to evaluate the efficacy and safety of methylphenidate in the initial treatment of acute mania in patients with bipolar affective disorders.

Enrollment: 42 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
