Tacrine

Tacrine is a prescription medicine that is used for treating mild to moderate Alzheimer's disease. It works by preventing a specific enzyme from breaking down acetylcholine (a chemical) in the brain. Tacrine capsules can help slow the decline of cognitive function, but it is not a cure for Alzheimer's. Potential side effects of tacrine include nausea, diarrhea, dizziness, and high liver enzymes.

 

What Is Tacrine?
