Experimentální: Armodafinil First, Then Placebo
During double-blind treatment subjects took armodafinil for 4 weeks before crossing over to placebo for 4 weeks. Pill is taken once daily, before 8 am. Armodafinil/placebo was initiated at a dose of 50 mg (1 tablet) and titrated to 150 mg after 1 week on the basis of the investigator's and patient's perception of efficacy and side-effects. After two weeks the medication could be increased to 250 mg or reduced back to 50 mg based on the investigator's and patient's perception of efficacy/side-effects. No increases in dosage were allowed after week 2. The dosage was decreased at a week 3 phone call if indicated on the basis of side-effects. |
