Extended release amantadine for reducing sleep disturbances in parkinson’s disease
A recently granted patent (Publication Number: US11903908B2) outlines a method for reducing OFF time in patients with Parkinson’s disease who are being treated with levodopa and experiencing OFF periods. The method involves orally administering a first composition containing 85 mg to 170 mg of a pharmaceutically acceptable salt of amantadine, followed by a second composition with about 300 mg to 380 mg of the same salt. The second composition is designed for extended release, and after at least 7 weeks of daily administration, a reduction in OFF time is observed. Importantly, the plasma concentration of amantadine in the patient increases by less than 10% at 1 hour post-administration of the second composition.
Furthermore, the patent details specific dosages, timing of administration, and pharmacokinetic parameters for optimal results. The method aims to increase ON time without troublesome dyskinesia, with a specific ratio of increased ON time to decreased OFF time. The reduction in OFF time is determined through a placebo-controlled, double-blind clinical study, where the total daily amount of OFF time is reduced by 10% to 40% compared to placebo. The compositions are formulated to provide extended release and specific plasma concentration profiles, ensuring steady-state levels for effective management of Parkinson’s symptoms. Overall, the method offers a targeted approach to improving treatment outcomes for patients with Parkinson’s disease experiencing OFF periods while on levodopa therapy.
