The present invention relates to a transdermal drug delivery system comprising of an adhesive layer consisting of a polyisobutylene pressure sensitive adhesive containing supersaturated rotigotine. The patches appeared to remain stable under accelerated temperature conditions for over one month, which translates to room temperature stability many times that duration, with the incorporation of various effective additives.本發明係關於一種包含由含有過飽和羅替戈汀(rotigotine)之聚異丁烯壓敏黏著劑組成之黏著劑層的經皮藥物遞送系統。貼片在併入各種有效添加劑之情況下在加速溫度條件下表現保持穩定超過一個月,其換算成室溫下之穩定性為該持續時間的許多倍。
