Brief Summary

The present clinical trial will be conducted in order to compare the bioavailability of rivastigmine and to assess bioequivalence at steady-state of the Test product RID-TDS 13.3 mg/24 h (Luye Pharma AG, Germany) and the marketed Reference product Exelon® 13.3 mg/24 h transdermales Pflaster (Novartis Pharma GmbH, Germany) after multiple patch applications. Each of both treatments will last for 11 days with a washout period of 14 days between the treatments.

• known allergic reactions to the active ingredients used or to constituents of the pharmaceutical preparations or previous history of application site reactions suggestive of allergic contact dermatitis with rivastigmine patch or scopolamine patch
