Estradiol enhances the mirtazapine effects on the expression of cocaine-induced locomotor sensitization in female rats.
Epidemiological studies have mentioned that cocaine use disorder (CUD) has increased in the last decade among women; these show endocrine and reproductive disorders and a high propensity to stress and depression disorders. Mirtazapine-a tetracyclic antidepressant-decreases cocaine-induced locomotor activity and locomotor sensitization in male rats. The objective of this study was to evaluate if estradiol alters the efficacy of mirtazapine to decrease cocaine-induced locomotor activity in sham and ovariectomized female rats. Three hundred and twenty adult female Wistar rats were assigned to three experimental protocols. For experiments, 1-3, female rats were daily dosed with 10 mg/kg of cocaine during the 10 days of induction and expression of locomotor sensitization. During drug withdrawal (30 days), cocaine was withdrawn and the groups received daily mirtazapine, estradiol, or saline. In addition, the females underwent sham or ovariectomy surgery. Tamoxifen was administered during the antagonism phase. After each administration, locomotor activity for each animal was recorded for 30 min in activity chambers. The dosage of mirtazapine reduces estradiol-induced enhancement in cocaine-dependent locomotor activity during the expression of locomotor sensitization in sham and ovariectomized female rats. As well as they showed that estradiol co-dosed with mirtazapine enhances the efficacy of mirtazapine to decrease cocaine-induced locomotor activity. Finally, tamoxifen enhanced the estradiol and mirtazapine-induced decrease in the cocaine motor effect in female rats. Mirtazapine may be considered an effective therapeutic option for the treatment of CUD in women, even in those who are on hormonal treatment or antidepressant therapy with estradiol.
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.
