Memantine is a low-affinity voltage-dependent uncompetitive antagonist at glutamatergic NMDA receptors. [32] [33] By binding to the NMDA receptor with a higher affinity than Mg 2+ ions, memantine is able to inhibit the prolonged influx of Ca 2+ ions, particularly from extrasynaptic receptors, which forms the basis of neuronal excitotoxicity.
The -NH 2 group on memantine, which is protonated under physiological pH of the body, represents the region that binds at or near to the Mg 2+ site. [18] Adding two methyl groups to the -N on the memantine structure has shown to decrease affinity, giving an IC 50 value of (28.4+1.4) μM.

NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. [1] Ketamine is a favored anesthetic for emergency patients with unknown medical history and in the treatment of burn victims because it depresses breathing and circulation less than other anesthetics.
A study confirmed that side effects like pancreatitis and kidney damage are possible while taking GLP-1s like Ozempic. Here's what a doctor wants you to know.
It found that doses of 5 milligrams (mg), 10 milligrams and 15 milligrams led to weight loss. ... 10 milligrams or 15 milligrams of tirzepatide or a placebo for 72 weeks, including 20 weeks when ...
Getting a raise is a huge accomplishment, so congratulations! Once the additional money starts rolling in, you’ll want to make sure to use it in the best possible way.
Memantine/donepezil, sold under the brand name Namzaric among others, is a fixed dose combination medication used for the treatment of dementia of the Alzheimer's type. [1] It contains memantine, as the hydrochloride, a NMDA receptor antagonist; and donepezil as the hydrochloride, an acetylcholinesterase inhibitor. [1] It is taken by mouth. [1]
