“In animals treated with both para-chlorophenylalanine and para-chloroamphetamine, ketanserin or the hallucinogenic agonist (2,5-dimethoxy-4-iodophenyl)-2-aminoethane (2C-I) each appeared to decrease stimulated GABA release but this was not significant.”
“In para-chlorophenylalanine-treated animals, stimulated GABA release in the presence of ketanserin remained depressed.”
“Under K+ stimulation, the antagonists ketanserin , spiperone, R-(+)-alpha-(2,3-dimethoxyphenyl)-1-[2-(4-fluorophenethyl)]- 4-piperidinemethanol (MDL 100,907) and ritanserin inhibited GABA release by 12-31%.”
