Abstract

Objective: Several studies have shown the influence of ovarian hormones on the GABAergic system. As women are naturally exposed to monthly fluctuation of these hormones, it is possible that their response to benzodiazepines also change over the ovarian cycle. Bearing this in mind, this study aimed to evaluate the possible influence of the ovarian cycle of healthy women on the acute effect of diazepam.

Methods: Forty subjectively healthy women were selected and randomly allocated to two different groups, according to their ovarian cycle phase, follicular (6 to 10 days from the first day of the cycle) or luteal (5 to 10 days after detection of urinary LH peak). Both groups completed the Video-Monitored Stroop Color-Word Test (VMSCWT), an experimental model of anxiety, under the influence of diazepam (10 mg) or placebo. Psychological parameters (State-Trait Anxiety Inventory, Self-evaluation of Tension Level, Visual Analogue Mood Scale) and physiological parameters (heart rate and gastrocnemius electromyogram activity) were evaluated throughout the test. All the data obtained were analyzed using analysis of variance (ANOVA) followed by Tukey’s test for post hoc comparisons, both at the 5% significance level.

Results: The results showed that, in the follicular phase, women did not respond to the anxiolytic action of diazepam, although a sedative effect was observed; while in the luteal phase, there was no response to either sedative or anxiolytic actions. As a control for the experimental conditions, a group of 18 men was also administered to the VMSCWT. The results confirmed that both the anxiogenic test and the administered drug were working as expected, since diazepam managed to prevent the anxiety induced by the test.

Conclusion: Therefore, the present findings indicate that the ovarian cycle can alter the effects of the acute administration of diazepam, which can vary from no effect to sedation, without going through anxiolysis.
