General description

Ifenprodil is a phenylethanolamine, which stimulates blood circulation. It has anticonvulsant and antinociceptive properties. Ifenprodil is used to treat posttraumatic stress disorder, cerebrovascular diseases and peripheral arterial obliterative disease. It blocks G protein-coupled inwardly-rectifying potassium channels (GIRKs) and interacts with α1 adrenergic, N-methyl-D-aspartate and serotonin receptors.

Application

Ifenprodil (+)-tartrate salt has been used:
  • to test the action in a KCl-induced cortical spreading depression (CSD) animal
  • to study its effects on electrophysiological properties and spontaneous spikes in neocortical pyramidal cells
  • to investigate its therapeutic effects

Biochem/physiol Actions

NMDA antagonist acting at the polyamine site; neuroprotective agent; α-adrenergic central and peripheral vasodilator; α2 adrenergic receptor ligand.
