A Double-Blind Placebo Controlled Trial of Riluzole in Bipolar Depression

Initially dispensed 50 mg capsules to take twice a day (BID). At two weeks, increase dose to 50 mg/100 mg. At four weeks increase to 100 mg BID (two capsules in the morning (qAM), two capsules in the evening (qHS). If significant side effects occur (at any time), titration can be slowed and doses can be reduced to a minimum daily dose of 50 mg/day, after which titration may resume by no more than 50 mg a week. Subjects who are unable to tolerate the minimal daily dose permitted in the study will be discontinued from further participation. In addition, if clinical remission is observed at a lower dose of study medication (defined as Montgomery Asberg Depression Rating Scale (MADRS) \< 12) the dose will not be increased further unless clinical symptoms recur.
