Efficacy of pramipexole in restless legs syndrome: A six‐week, multicenter, randomized, double‐blind study (effect‐RLS study)We evaluated the efficacy of pramipexole versus placebo in restless legs syndrome (RLS) for 6 weeks. Overall, 345 patients were randomly assigned in a 1:2 ratio to receive either placebo (n = 115) or pramipexole (n = 230) with a starting dose of 0.125 mg/day. The dose was individually optimized according to the Patient Global Impression (PGI) assessment, up to a maximum of 0.75 mg/day. The primary endpoint consisted of two assessments: the change from baseline in the International RLS Study Group Rating Scale (IRLS) and the proportion of patients with Clinical Global Impressions-Improvement (CGI-I) assessments of "much/very much improved" (CGI-I responders) at week 6. Secondary endpoints included PGI and IRLS responder rates. Patient demographics and baseline characteristics were comparable between treatment groups. At baseline, mean IRLS scores were 24.9 (placebo) and 24.7 (pramipexole), representing severely affected patients. After 6 weeks, adjusted mean reductions (+/-SE) in IRLS score were 5.7 (+/-0.9) for placebo (median dose 0.47 mg/day) and 12.3 (+/-0.6) for pramipexole (median dose 0.35 mg/day; P < 0.0001). CGI-I responder rates were 32.5% (placebo) and 62.9% (pramipexole) (P < 0.0001). For all secondary endpoints, pramipexole showed superior results. Pramipexole was well tolerated throughout the study.
First clinical experience with levodopa/carbidopa microtablets in Parkinson's diseaseMarina Senek, Mats Hellström, Jaan Albo et al.|Acta Neurologica Scandinavica|2017 BACKGROUND: Levodopa is the most effective symptomatic treatment throughout the course of Parkinson's disease, but as the disease progresses, there may be a need for individualized, fine-tuned treatments. AIM: To evaluate individualized levodopa/carbidopa dosing using microtablets dispensed with a dose dispenser, with respect to efficacy and usability as perceived by patients. METHODS: Patient records and dose dispenser reports from patients previously or currently treated with microtablets and a dose dispenser were reviewed, and a patient questionnaire concerning effect and usability was sent to patients. RESULTS: Eleven patient records, four dose dispenser reports and nine survey responses were obtained. The treatment effect was considered to be improved by six of nine patients. One-third found their bradykinesia to be improved, and the non-troublesome dyskinesia was unchanged according to a majority of patients; however, some experienced the duration and magnitude of troublesome dyskinesia to be worse. The usability was generally rated as good. The four dose dispenser reports obtained showed 97(±5)% total adherence. CONCLUSIONS: The experienced effect of treatment can, for some patients, be improved by the use of microtablets, and the dose dispenser was considered user-friendly. Further studies with a larger study population and prospective design are needed to confirm the results.
