1 What is Razadyne?

Brand: Razadyne, Razadyne ER, Razadyne IR

Generic: Galantamine

Razadyne is used for the management of dementia (memory loss and mental changes) in the patients with Alzheimer’s disease. 

This drug cannot cure the Alzheimer’s disease; rather it is just used to manage the symptoms of Alzheimer’s. It will stop the progression of symptoms. 

Razadyne has also shown to improve the thinking ability in some patients with Alzheimer’s. A lot of chemical changes take place in the brain of a patient with Alzheimer’s disease. 

One of these changes is that there’s lack of a chemical called acetylcholine (Ach). Acetylcholine is necessary for the proper functioning of the brain. 

Razadyne decreases the rate of deterioration of Ach in the brain which results in a greater effect of Ach. However, the levels of Ach decrease further and further in an Alzheimer patient, so its effect may not be permanent.

This medicine is only available through a doctor's prescription. This product is available in the following dosage forms:

  • Capsule, Extended Release
  • Tablet
  • Solution
