Gamine XR is used to treat mild to moderately severe dementia of the Alzheimer's type.
The symptoms of Alzheimer’s disease include confusion, memory loss or other changes in behaviour. As the disease progresses, patients find it more and more difficult to carry out their normal daily activities.
The symptoms of Alzheimer’s disease are thought to be due to a lack of acetylcholine, a substance which transmits messages between brain cells. Gamine XR increases the amount of this substance to help improve or stabilise the symptoms and therefore slow the progress of Alzheimer’s disease.
Your doctor may have prescribed this medicine for another reason.

Initial results from clinical trials in patients with mild cognitive impairment of various causes have shown a slightly higher mortality rate (higher death rate) in those taking Gamine XR than those taking placebo (a pill without an active ingredient which is commonly used in clinical trials as a reference for comparison). The reason for this difference is currently not known and may just be due to chance. There is no evidence of increased risk of death in those with mild to moderately severe Alzheimer's disease taking Gamine XR.
