Suritozole is an inverse agonist at the GABA(A) receptor (Miller et al., 1992). GABA(A) receptor activity affects cholinergic function in the hippocampus and cerebral cortex (Richter et al., 1982; Wenk, 1984). This drug was found to improve memory performance in rats with scopolamine-induced memory acquisition deficits (Moran et al., 1992).
