Abstract:
Medical students experience significant psychological stress and are therefore at higher risk of using sedatives. There are currently no studies describing the prevalence of sedative drug use among medical students in Ethiopia. This study aimed to assess the prevalence and associated factors of self-reported sedative drug use among medical students attending the College of Medicine and Health Science (CMHS) students at the University of Gondar (UoG).A prospective cross-sectional study was conducted from May to July 2018 in CMHS at UoG. Data were collected using a pre-tested self-administered standard questionnaire. Data were collected, entered into a computer using Epi Info 7 software, and analyzed using SPSS version 20. Frequency, mean, and standard deviation were used to describe descriptive statistics, and binary and multiple logistic regression analyses were used to assess the association between different variables and sedative drug use; P <0.05 was used to declare association.Of the 422 students who returned questionnaires, 26 (6.2%) participants were reported sedative drug use at some time since enrollment. Of these, 61.54% participants used antihistamine drugs. Smoking status (AOR (95% CI), 0.046 (0.009-0.241) P = 0.0001), stimulant use (AOR (95% CI), 0.220 (0.062-0.780) P = 0.019), sleeping hour (AOR (95% CI), 9.931 (4.155-14.785) P = 0.001) and sleep disorder (AOR (95% CI), 0.149 (0.033-0.680) P = 0.014) were significantly associated with sedative drug use.Self-reported sedative drug use among medical students at the University of Gondar is relatively low, and antihistamines are the most commonly used drugs. Smoking, stimulant use, sleeping hour, and the presence of sleep disorders were associated with sedative drug use.Keywords:

Ethanol exerts both stimulant‐like and sedative‐like subjective and behavioral effects in humans depending on the dose, the time after ingestion and, we will argue, also on the individual taking the drug. This study assessed stimulant‐like and sedative‐like subjective and behavioral effects of ethanol during the ascending and descending limbs of the blood alcohol curve across a range of doses in nonproblem social drinkers. Forty‐nine healthy men and women, 21 to 35 years old, consumed a beverage containing placebo or ethanol (0.2, 0.4, or 0.8 g/kg) on four separate laboratory sessions, in randomized order and under double‐blind conditions. Subjective and behavioral responses were assessed before and at regular intervals for 3 hr after ingestion of the beverage. The lowest dose of ethanol (0.2 g/kg) only produced negligible subjective effects compared to placebo. The moderate dose (0.4 g/kg) increased sedative‐like effects 90 min after ethanol ingestion but did not increase ratings of stimulant effects at any time. The highest dose (0.8 g/kg) increased ratings of both stimulant‐ and sedative‐like effects during the ascending limb and produced only sedative‐like effects during the descending limb. Closer examination of the data revealed that individual differences in response to the highest dose of ethanol accounted for this unexpected pattern of results: about half of the subjects reported stimulant‐like effects on the ascending limb and sedative‐like effects on the descending limb after 0.8 g/kg ethanol, whereas the other half did not report stimulant‐like effects at any time after administration of ethanol. These results challenge the simple assumption that ethanol has biphasic subjective effects across both dose and time, and extend previous findings demonstrating individual differences in response to ethanol.

Anticipations of alcohol's effects reportedly covary with the amount consumed. Alcohol's stimulant and sedative properties also may contribute to alcohol consumption. Anticipations of stimulant and sedative effects have not been investigated extensively. The present study examined the stimulant and sedative effects subjects anticipated experiencing if they were on the ascending or descending limb of the blood alcohol curve after consuming two or four standard drinks. One hundred sixty-six undergraduates reported anticipating greater stimulant effects than sedative effects on the ascending limb of the blood alcohol curve, and greater sedative effects than stimulant effects on the descending limb. Subjects also reported anticipating larger effects with larger doses. Men tended to anticipate smaller effects than women. These results support the notion that specific anticipated effects vary with dosage and the limb of blood alcohol curve, suggesting that the study of anticipated effects of alcohol should employ these variables.

Objective: Research on low subjective response to alcohol has focused primarily on alcohol's sedative effects during early drinking experiences. This study examined subjective response to both stimulant and sedative effects of alcohol during initial drinking experiences as predictors of treated adolescents' severity of alcohol involvement before treatment and over 1-year follow-up. Method: Adolescents (N = 169) recruited from addictions treatment reported on the number of drinks needed to obtain stimulant and sedative effects of alcohol for early and heavy drinking periods. The number of drinks needed to obtain stimulant and sedative effects, as well as the degree of stimulant and sedative effect obtained, were examined as predictors of adolescents' alcohol involvement at baseline (before treatment) and 1-year follow-up. Results: During early drinking experiences, females reported a greater degree of sedative effect compared with males; there was no gender difference in degree of stimulant effect reported during early drinking experiences. Both early subjective stimulant and sedative effects of alcohol predicted the usual number of drinks needed to become intoxicated and the maximum drinking quantity per day before treatment. However, at 1-year follow-up, only early sedative effects predicted 1-year outcomes. Conclusions: Study findings suggest potentially important roles for both early subjective stimulant and sedative effects of alcohol in relation to adolescent alcohol involvement. (J. Stud.

Ethanol exerts both stimulant-like and sedative-like subjective and behavioral effects in humans depending on the dose, the time after ingestion and, we will argue, also on the individual taking the drug. This study assessed stimulant-like and sedative-like subjective and behavioral effects of ethanol during the ascending and descending limbs of the blood alcohol curve across a range of doses in nonproblem social drinkers. Forty-nine healthy men and women, 21 to 35 years old, consumed a beverage containing placebo or ethanol (0.2, 0.4, or 0.8 g/kg) on four separate laboratory sessions, in randomized order and under double-blind conditions. Subjective and behavioral responses were assessed before and at regular intervals for 3 hr after ingestion of the beverage. The lowest dose of ethanol (0.2 g/kg) only produced negligible subjective effects compared to placebo. The moderate dose (0.4 g/kg) increased sedative-like effects 90 min after ethanol ingestion but did not increase ratings of stimulant effects at any time. The highest dose (0.8 g/kg) increased ratings of both stimulant- and sedative-like effects during the ascending limb and produced only sedative-like effects during the descending limb. Closer examination of the data revealed that individual differences in response to the highest dose of ethanol accounted for this unexpected pattern of results: about half of the subjects reported stimulant-like effects on the ascending limb and sedative-like effects on the descending limb after 0.8 g/kg ethanol, whereas the other half did not report stimulant-like effects at any time after administration of ethanol.

Participants discriminated between tripelennamine and placebo in experiments differing in instructional set. In 1 experiment (SED), participants were told that 1 of the 2 drugs was more sedative-like, and during the other (STIM), 1 was more stimulant-like. During generalization tests, participants received diazepam or d-amphetamine. Percent correct was the same in both experiments. Tripelennamine increased sedative and decreased stimulant effects. Amphetamine and diazepam produced typical subjective effects. Some subjective effects differed across experiments with more sedative and less stimulant effects during SED than STIM. In SED and STIM, capsules were labeled 80% of the time as a sedative and stimulant, respectively. Thus, instructions designed to give expectations had no effect on discrimination and only a few changes in subjective effects. When asked to name the drug that they believed they received, labels reflected instructional set.

To investigate patterns and trends of co-prescriptions of stimulants and sedatives within the last 6 years at a tertiary care center.Patients 18 years of age and older who were dispensed at least one stimulant prescription from an institutional pharmacy between 1/1/2015 and 7/1/2021 were included. Prescription data for any co-prescribed sedative/hypnotic were collected.Both the number of stimulant dispenses and the number of patients with stimulant dispenses increased significantly with yearly incidence rate ratios of 1.115 (95% CI [1.110, 1.119]) and 1.090 (95% CI [1.084, 1.096]), respectively. The number of patients with a stimulant dispensed who also had a benzodiazepine or "Z-drug" sedative-hypnotic dispensed at any point in the search timeframe increased significantly with incidence rate ratios of 1.077 and 1.092, respectively. The number of stimulant dispenses, number of patients with stimulant dispenses, and number of patients with a stimulant dispensed who also had both a benzodiazepine and Z-drug dispensed at any point in the search timeframe increased significantly more in Non-White than in White patients.The results confirm previous findings of increases in dispensing of stimulants over the past 6 years and report increased polypharmacy of stimulants and sedative-hypnotics.
