Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Evaluating the potential for additive or synergistic effects of alcohol when coadministered with remimazolam. Female subjects were selected because they represent the population at greatest risk for victimization in drug-facilitated sexual assault. In addition, females have a slower ethanol metabolism, therefore, the effects of remimazolam, if coadministered with alcohol, may last longer. Hence, this population represents the worst-case scenario in evaluating the risk of remimazolam misuse in drug-facilitated assault.

5. Weight : ≥ 50 kg
6. Body mass index (BMI) : 18.0 to 33.0 kg/m2, inclusive
7. Healthy status, defined by the absence of evidence of any clinically significant, in the opinion of the Investigator, active or chronic disease following a detailed medical and surgical history, a complete physical examination including vital signs, 12-lead electrocardiograms (ECG), hematology, blood chemistry, serology, and urinalysis.
8. Current alcohol user classified as a moderate drinker, defined as drinking \> 2 drinks/week and ≤ 14 drinks/week (1 drink equals approximately 12 oz/350 mL of beer, 5 oz/150 mL of wine, or 1.5 oz/45 mL of spirits).6
9. Ability and willingness to abstain from alcohol, caffeine, and xanthine-containing beverages or food (eg, coffee, tea, cola, chocolate, energy drinks) from 48 hours (2 days) prior to admission to the clinical facility on Day -1 until trial discharge.
10. All values for hematology and for clinical chemistry tests of blood and urine within the normal range or showing no clinically relevant deviations, as judged by the Investigator.
11. A negative pregnancy test at Screening and Day -1.
12. Females of childbearing potential must have agreed to use 2 forms of contraception, one of which must have been a barrier method, during the trial and for 90 days after the last drug administration. Acceptable barrier forms of contraception were condom and diaphragm. Acceptable nonbarrier forms of contraception for this trial were oral contraceptives, injectable hormone contraceptives, implantable birth control, intrauterine devices, and/or spermicide. Injectable hormonal contraception was allowable as a nonbarrier method.
13. Females who were not of childbearing potential, including postmenopausal females (defined as 12 months with no menses prior to Screening and a serum follicle-stimulating hormone \[FSH\] \> 40 IU/L at Screening) or females who were surgically sterilized.

Exclusion Criteria

1. Females who were pregnant or lactating.
2. Known intolerance towards alcohol (symptoms could include nausea, flushed face, vomiting, or hypotension upon drinking) or known alcohol dehydrogenase deficiency.
3. of Asian descent (one or both parents) due to potential for genetic polymorphism related to aldehyde dehydrogenase deficiency.

11. History of donation or loss of more than 450 mL of blood or blood products within 60 days prior to dosing in the clinical research center or planned donation before 30 days had elapsed since intake of trial drug in the current trial.
12. Positive screening test for hepatitis B surface antigen (HBsAg), anti-hepatitis C Virus (HCV) antibodies, or anti-human immunodeficiency virus (HIV) 1 and 2 antibodies.
13. Positive drug and alcohol screen (opiates, methadone, cocaine, amphetamines \[including ecstasy\], cannabinoids, barbiturates, benzodiazepines, tricyclic antidepressants, and alcohol) at Screening and admission to the clinical research center.
14. Average intake of \> 14 drinks of alcohol per week (1 drink equals approximately 12 oz/350 mL of beer, 5 oz/150 mL of wine, or 1.5 oz/45 mL of spirits).
15. Required concomitant treatment with any prescription or non-prescription medications (with the exception of hormonal contraceptives, hormone replacement, and acetaminophen) or natural health products (herbal remedies), or respiratory depressants, or could not safely discontinue these medications at least 7 days prior to receiving trial drug.
