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.
