What is "gavestinel"

n. A drug that acts as an NMDA antagonist.

Gavestinel (GV-150,526) was an investigational drug developed by GlaxoSmithKline for acute intracerebral hemorrhage, which in 2001 failed to show an effect in what was at the time, the largest clinical trial in stroke that had been conducted.

Gavestinel is an NMDA antagonist, binding selectively to the glycine site on the NMDA receptor complex, rather than the glutamate site many NMDA antagonists bind to.
