Introduction

Rivamer is an acetylcholinesterase inhibitor belonging to the class of drugs called cholinomimetics. It is prescribed for treatment of mild to moderate dementia due to Alzheimer’s disease or Parkinson’s disease. It is also used to slow the behavioral and psychological symptoms of dementia, including aggression, anxiety, confusion, mood swings, and hallucinations.

Uses
