Study Arms (2)

Oral treatment started at a daily dose of 1 mg tablets for the first 7 days; thereafter the daily dosage was titrated at a maximum rate of 1 mg every 7 days up to a maximum dosage of 6 mg for lack of response, and in the absence of dose-limiting adverse events; no further increases in daily dose were permitted after Day 36; dosage reductions were permitted if required for tolerability; subjects who were not eligible for entry into the 18-week continuation study, or who were eligible but elected not to participate, were tapered off study drug at a rate of 1 mg every 7 days for up to a 6-week taper period.
