Rivastigmine Mini-Tablet for Alzheimer's Disease

Observational Study of Rivastigmine Mini-Tablet in Patients with Alzheimer's Disease

The objective of this study is to evaluate the efficacy and safety of rivastigmine mini-tablets in individuals diagnosed with mild to moderate Alzheimer's disease (AD).

Rivastigmine has received approval for the treatment of Alzheimer's disease. The rivastigmine mini-tablet represents an innovative drug formulation designed to address swallowing difficulties by reducing the size of the dosage form, while also minimizing gastrointestinal side effects through an optimized drug release mechanism. This multi-center, observational study aims to evaluate the effectiveness, safety, and patient compliance associated with rivastigmine mini-tablets in individuals diagnosed with Alzheimer's disease. Assessments will be conducted at the 3rd, 6th, and 12th months of treatment.
