Eliprodil, also known as SL 82-0715, is a non-competitive NMDA glutamate receptor antagonist, which targets the polyamine modulatory site and is selective for NR2B subunit-containing receptors. Eliprodil was in phase III clinical trial for the treatment of stroke or traumatic brain injury. However, these investigations were failed. One reason suggested for failure was that eliprodil had blocked the synaptic transmission mediated by NMDA receptors, hindering neuronal survival. In addition, eliprodil has been studied in phase II clinical trials for the treatment of Parkinson's disease.

Curator's Comment: Pharmacologically, the development of clinically useful NMDA antagonists has been difficult, because many competitive and non-competitive antagonists of this receptor are unable to cross the blood-brain barrier, and many others produce undesirable (psychotomimetic) side effects. Unlike other NMDA antagonists, the polyamine site antagonists, such as eliprodil, partition across the blood-brain barrier and produce their actions at a modulatory site without side effects typical of many non-competitive antagonists.

Curator's Comment: eliprodil is most often administered intravenously, although it has also been used orally in humans and animals, and as an intraperitoneal injection in animals.
IV 1.5 mg and 3.0 mg twice daily for 3 days, IV 5.0 mg and 10.0 mg twice daily for 11 days, IV between 2.5 mg and 10 mg per dose,
or: 3 mg b.i.d for 3 days iv, followed by 10 mg b.i.d for 11 days p.o and 1,5 mg bid for 3 days i.v, then 5 mg b.i.d for 11 days p.o with 3 month follow-up.
Route of Administration:
Other
The effect of eliprodil on P-type Ca2+ channels was investigated in acutely dissociated rat Purkinje neurons, by using the whole-cell patch-clamp technique. Eliprodil inhibited in a reversible manner the omega-agatoxin-IVA-sensitive Ba2+ current elicited by step depolarizations from a -80 mV holding voltage (IC50 = 1.9 microM). The Ba2+ current showed steady-state inactivation (V1/2 = -61 mV) which was shifted toward more positive values when the intracellular Ca2+ buffering was increased. In these conditions, the potency of eliprodil was decreased (IC50 = 8.2 microM), suggesting a modulation by intracellular Ca2+ of the eliprodil blockade.
