Rasagiline may slow progression of Parkinson’s disease


A large, delayed-start, designed trial in 1,176 patients with early-stage Parkinson’s disease suggests that early initiation of rasagiline (Azilect—Teva) 1 mg/d may slow disease progression. Some experts are skeptical, however, because the clinical significance of improvements between early and delayed initiation appeared modest, and early initiation of 2 mg/d, a nonapproved dose, did not result in statistically significant findings.
