Uses

Zunveyl (benzgalantamine) is commonly used to treat mild to moderate dementia related to Alzheimer’s disease.

Zunveyl may also be used for other conditions as determined by your healthcare provider.

How does Zunveyl work (mechanism of action)?

People with Alzheimer’s disease typically have a decrease in the amount of acetylcholine in their brain. Acetylcholine is a natural chemical in the brain that helps carry messages between brain cells. When there is less acetylcholine, it leads to problems in memory and thinking. Zunveyl may help manage symptoms of Alzheimer’s disease by preventing the breakdown of acetylcholine, allowing more acetylcholine to build up in the brain.

Zunveyl is available in the following dosage forms that are taken by mouth.

  • 5 mg delayed-release oral tablets
  • 10 mg delayed-release oral tablets
  • 15 mg delayed-release oral tablets
