Interaction Details
Memantine Hydrochloride is classified as belonging to the following category: Oral Drugs
Theoretically, algin can alter the absorption of oral drugs. Laboratory research shows that algin, when consumed as part of the diet or used as a thickening agent in infant formula, reduces the absorption of certain minerals. Also, algin has been used as a tablet binder and disintegrant to enhance drug bioavailability. To avoid changes in absorption, take algin 30-60 minutes after oral medications.

Memantine Hydrochloride Overview
-
Memantine is used to treat the symptoms of Alzheimer's disease (AD; a brain disease that slowly destroys the memory and the ability to think, learn, communicate and handle daily activities). Memantine is in a class of medications called NMDA receptor antagonists. It works by decreasing abnormal activity in the brain. Memantine may improve the ability to think and remember or may slow the loss of these abilities in people who have AD. However, memantine will not cure AD or prevent the loss of these abilities at some time in the future.
