Placebo-controlled study of the efficacy and safety of lamotrigine in patients with partial seizures. U.S. Lamotrigine Protocol 0.5 Clinical Trial Group.

Journal Article Neurology · November 1993 We evaluated the efficacy and safety of lamotrigine (300 and 500 mg/day) as add-on therapy in a multicenter, randomized, double-blind, parallel-group, placebo-controlled study of 216 patients with refractory partial seizures. During 6 months of treatment, ... Full text Link to item Cite

Does sigma receptor antagonism predict clinical antipsychotic efficacy?

Journal Article Psychopharmacology bulletin · January 1991 The psychotogenic actions of sigma receptor agonists, such as pentazocine, have led to the hypothesis that sigma receptor antagonists may be putative antipsychotic agents. In this study, BW234U, a selective but relatively weak sigma receptor antagonist was ... Cite

BW234U: a non-dopamine receptor blocking antipsychotic drug without extrapyramidal effects?

Journal Article Drug Development Research · 1985 Based on studies in animals and in healthy human volunteers, it was predicted that the carbazole compound BW234U would have antipsychotic effects in patients without producing concomitant extrapyramidal effects. The compound was administered to 22 inpatien ... Cite

Open-label evaluation of the novel antipsychotic compound BW234U in chronic schizophrenics.

Journal Article Drug Development Research · 1985 In a 28-day open label study, 15 inpatients with chronic schizophrenia in relapse were treated with BW234U. Approximately half of the patients showed marked improvement. Four patients showed no change and three dropped out. Thought disturbance improved mar ... Full text Cite

N-o-Methoxyphenylpiperazine: a simple blocker of dopaminergic receptors in the brain.

Journal Article The Journal of pharmacy and pharmacology · February 1979 N-o-Methoxyphenylpiperazine (MPP) is a moderately effective in vivo blocker of dopaminergic receptors. Its ability to increase the concentration of rat brain homovanillic acid (HVA) and the resulting time course for HVA were similar to the actions of cloza ... Full text Cite

Local anesthetic activity and acute toxicity of N-substituted 1,2,3,4-tetrahydro-1- and 2-naphthylamines.

Journal Article Journal of pharmaceutical sciences · June 1978 Seven N-substituted 1,2,3,4-tetrahydro-1- and three 2-naphthylamines were prepared and tested for local anesthetic activity in the rabbit corneal reflex test and the mouse sciatic nerve block test. At 0.1 and 1%, three 1-alkylamino compounds had durations ... Full text Cite
