Midafotel (CPPene; SDZ EAA 494) is a selective competitive antagonist at the N-methyl-D-aspartate (NMDA) subtype of glutamate receptor. It was originally designed as a potential therapy for excitotoxicity, epilepsy or neuropathic pain. Midafotel had been in phase III clinical trials by Novartis for the treatment of brain injury. However, this research has been discontinued.

Sample Use Guides

In Vivo Use Guide

Midafotel was administered either as single doses at a dose range of 1-50 mg, or as multiple doses over the course of 1 week at doses of 25 mg once or twice daily.

Route of Administration: Oral

In Vitro Use Guide

Midafotel (d-CPPene) strongly inhibited the frequency of spontaneous epileptiform discharges. This effect was concentration-dependent. Epileptiform discharges were reduced up to 70% at a concentration of 0.1 uM and were completely blocked at a concentration of 0.3 uM in the rat cortical wedge preparation. d-CPPene inhibited in concentration-dependent manner NMDA-induced depolarisations. A concentration of 0.1 uM that blocked 70% of spontaneous discharges inhibited 60% of depolarisations induced by NMDA. A concentration of 1 uM completely blocked NMDA-induced depolarisations.
