Impact of fluoxetine preexposure on MDMA-induced taste avoidance in male and female rats.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The use of both prescription and illicit drugs creates the potential for drug interactions as a function of both pharmacokinetic and pharmacodynamic processes. One such interaction is that of fluoxetine and methylenedioxymethamphetamine (MDMA) in which fluoxetine attenuates the positive-like effects of MDMA. The present work extends the analysis of their interaction by examining the impact of fluoxetine on the aversive effects of MDMA which in balance with its rewarding effects may mediate its abuse potential. Male and female Sprague-Dawley rats were given fluoxetine (10 mg/kg every 4th day for five injections) prior to taste avoidance training with MDMA (3.2 mg/kg). MDMA induced taste avoidance in males and females (faster acquisition in females). Fluoxetine preexposure attenuated this avoidance in males, but not females. For males, the attenuation was partial as MDMA-conditioned animals with fluoxetine preexposure still displayed a significant reduction in fluid intake compared to controls. Consistent with prior work assessing the interaction of fluoxetine and MDMA, fluoxetine preexposure impacted the ability of MDMA to support taste avoidance learning, specifically attenuating the aversive effect of the drug. Prior work has shown that fluoxetine attenuates MDMA's positive effects which might lead to reduced intake of the drug; however, the concurrent reduction in the drug's aversive effects may still shift the overall affective balance of these two affective properties toward continued use and abuse. The fact that the attenuation was only evident in males needs further study to investigate the sex-dependent effects of drug history. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
