Clinical studies indicate that adjunctive treatment with the antidepressant drug mianserin, a 5-hydroxytryptamine (5-HT)(2A/C) receptor antagonist and an alpha(2)- and alpha(1)-adrenoceptor antagonist, may enhance the effect of conventional antipsychotic drugs in schizophrenia, in particular on negative symptoms such as withdrawal retardation, akathisia, and some aspects of cognitive impairment...

Gabapentin, a drug used to treat neuropathic pain, was evaluated in models of acute nociceptive pain, in instances of haloperidol-induced catalepsy, carrageenan-induced paw edema, gastric lesions caused by indomethacin or ethanol, and gastric acid secretion in rats. Reaction time in a hot plate assay was delayed by gabapentin. The antinociceptive effect of the drug was produced with a dose of 1...

Objective: To investigate the effect of the methanolic extract of Hibiscus rosa sinensis roots (H. sinensis) on the central nervous system in mice and rats. Materials and methods: The methanolic extract of H. sinensis was studied on pentobarbital-induced sleeping time, elevated plus maze, hole board test, foot shock-induced aggression, haloperidol-induced catalepsy, lithium-induced head twitche...

Objective: The present study was undertaken to evaluate the antidepressant and nootropic potential of aqueous extract of Indigofera tinctoria (ITAE). Methods: Antidepressant activity of ITAE was evaluated in mice by using the forced swim test (FST), tail suspension test tail suspension test and tetrabenazine induced catalepsy and ptosis models at doses of 250 and 500 mg/kg orally. Nootropic act...
