Abstract
2,5-dimethoxy-4-methylamphetamine (DOM) is a kind of hallucinogen of phenylalkylamine. Psychedelic effects mainly include audiovisual synesthesia, complex imagery, disembodiment etc. that can impair control and cognition leading to adverse consequences such as suicide. By now, there are no specific drugs regarding the management of classic hallucinogen use clinically. We evaluated the effects of three 5-HT 2A receptor antagonists ketanseirn, M100907 and olanzapine on hallucination-like behavior in therapeutic and preventive administration with male C57BL/6J mice. Two models were used to evaluate the therapeutic potential of antagonists, one is head-twitch response (HTR) and the other is locomotion. Effects of ketanserin, M100907 and olanzapine on DOM-induced HTR were studied in preventive and therapeutic administration, respectively. In the preventive administration, the ID 50 values of ketanseirn, M100907 and olanzapine were 0.4 mg/kg, 0.005 mg/kg and 0.25 mg/kg. In the therapeutic administration, the ID 50 values of ketanseirn, M100907 and olanzapine were 0.04 mg/kg, 0.005 mg/kg and 0.03 mg/kg. Secondly, locomotor activity induced by DOM was performed to further evaluate the efficacy of three compounds. In locomotion, M100907(0.005 mg/kg) whenever in preventive or therapeutic administration, reduced the increase of movement distance induced by DOM. Although ketanserin (0.4 mg/kg) in the preventive administration also decreased the movement distance induced by DOM, it was alone administrated to influence the locomotor activity. Through HTR and locomotion, we compared the efficacy and latent side effects of ketanserin, M100907 and olanzapine against hallucinogenic like action induced by DOM. Our study provided additional experimental evidence on specific therapeutic drugs against hallucinogenic behavior induce by representative hallucinogen DOM.
期刊介绍:
Behavioural Pharmacology accepts original full and short research reports in diverse areas ranging from ethopharmacology to the pharmacology of schedule-controlled operant behaviour, provided that their primary focus is behavioural. Suitable topics include drug, chemical and hormonal effects on behaviour, the neurochemical mechanisms under-lying behaviour, and behavioural methods for the study of drug action. Both animal and human studies are welcome; however, studies reporting neurochemical data should have a predominantly behavioural focus, and human studies should not consist exclusively of clinical trials or case reports. Preference is given to studies that demonstrate and develop the potential of behavioural methods, and to papers reporting findings of direct relevance to clinical problems. Papers making a significant theoretical contribution are particularly welcome and, where possible and merited, space is made available for authors to explore fully the theoretical implications of their findings. Reviews of an area of the literature or at an appropriate stage in the development of an author’s own work are welcome. Commentaries in areas of current interest are also considered for publication, as are Reviews and Commentaries in areas outside behavioural pharmacology, but of importance and interest to behavioural pharmacologists. Behavioural Pharmacology publishes frequent Special Issues on current hot topics. The editors welcome correspondence about whether a paper in preparation might be suitable for inclusion in a Special Issue.
