Premedication with oral alprazolam and melatonin combination: a comparison with either alone--a randomized controlled factorial trial.

ABSTRACT: We assessed if the addition of melatonin to alprazolam has superior premedication effects compared to either drug alone. A prospective, double blind placebo controlled trial randomly assigned 80 adult patients (ASA 1&2) with a Visual Analogue Score (VAS) for anxiety ? 3 to receive a tablet containing a combination of alprazolam 0.5 mg and melatonin 3 mg, alprazolam 0.5 mg, melatonin 3 mg, or placebo orally 90 min before a standard anesthetic. Primary end points were change in anxiety and sedation score at 15, 30, and 60 min after premedication, and number of patients with loss of memory for the five pictures shown at various time points when assessed after 24 h. One-way ANOVA, Friedman repeated measures analysis of variance, Kruskal Wallis and chi square tests were used as relevant. Combination drug produced the maximum reduction in anxiety VAS (3 (1.0-4.3)) from baseline at 60 min (P < 0.05). Sedation scores at various time points and number of patients not recognizing the picture shown at 60 min after premedication were comparable between combination drug and alprazolam alone. Addition of melatonin to alprazolam had superior anxiolysis compared with either drugs alone or placebo. Adding melatonin neither worsened sedation score nor the amnesic effect of alprazolam alone. This study was registered, approved, and released from ClinicalTrials.gov. Identifier number: NCT01486615.

Project description:BACKGROUND:Perioperative anxiety is common in pediatric patients undergoing surgery. AIMS:The aim of this study was to determine whether an infusion of dexmedetomidine prior to hernia repair in children provides better postoperative anxiety outcomes that a preoperative infusion of midazolam. METHODS:Ninety 6-11-year-old children, who were scheduled to undergo elective hernia repair, were enrolled for this double-blind, randomized controlled trial. Group D (n = 45) received an intravenous infusion of dexmedetomidine (0.5 ?g/kg) and Group M (n = 45) received an intravenous infusion of midazolam (0.08 mg/kg) in 20 mL of normal saline for 10 minutes before the induction of anesthesia. Pre- and postoperative scores on the modified Yale Preoperative Anxiety Scale were the main outcomes. Secondary outcomes included systolic blood pressure, diastolic blood pressure, heart rate, and postoperative pain measured on a visual analogue scale and patient satisfaction using a numerical rating scale. RESULTS:Postoperative anxiety in Group D was significantly lower than preoperative anxiety (2 hours postoperatively mean difference [95% CI]: 2.83 [0.87-4.79], P = 0.036, 4 hours postoperatively mean difference [95% CI]: 3.29 [1.39-5.20], P = 0.005). Preoperative and postoperative anxiety in Group M was similar. Anxiety scores in Group D were also significantly lower than anxiety in Group M 2 hours (mean difference [95% CI]: 1.89 [0.52-3.26], P = 0.01) and 4 hours (mean difference [95% CI]: 3.32 [1.98-4.66], P < 0.001) postoperatively. Systolic blood pressure, diastolic blood pressure and heart rate were lower in Group D than in Group M after administration of sedative drugs until children left PACU (SBP mean difference [95% CI]: 13.87 [10.30-17.43], P < 0.001, DBP mean difference [95% CI]: 5.96[3.80-8.11], P < 0.001, HR mean difference [95% CI]: 10.36 [7.58-13.13], P < 0.001). Pain was also significantly lower in Group D than in Group M at 2 hours (median difference [95% CI]: 1 [0.26-1.34], P = 0.004), 4 hours (median difference [95% CI]: 1 [0.31-1.02], P = 0.003), and 1 day (median difference [95% CI]: 0 [0.22-0.76], P = 0.003) postoperatively. Patient satisfaction scores were significantly higher in Group D than in Group M 1 day (median difference [95% CI]: 0 [-0.83 to -0.24], P = 0.006) and somewhat higher 1 week (median difference [95% CI]: 0 [-0.67 to -0.04], P = 0.06) postoperatively. CONCLUSION:Compared with midazolam, a single preoperative intravenous dose of dexmedetomidine appears to provide better postoperative anxiolytic effects for children undergoing same-day surgery.

Project description:BackgroundAdjustment disorder with anxiety (ADWA) is a highly prevalent condition, particularly in primary care practice. There are relatively few systematic treatment trials in the area of ADWA, and there are few data on predictors of treatment response. Etifoxine is a promising agent insofar as it is not associated with dependence, but in primary care settings benzodiazepines continue to be frequently prescribed for psychiatric symptoms. A randomized controlled trial of etifoxine versus alprazolam for ADWA was undertaken, focusing on efficacy and safety measures, and including an investigation of predictors of clinical response.MethodsThis was a comparative, multicenter, double-blind, randomized trial in two parallel groups of outpatients with ADWA. One group was treated with 150 mg/day for etifoxine, and the other with 1.5 mg/day for alprazolam for 28 days. Patients were followed for 4 weeks of treatment, and for an additional week after treatment discontinuation. The primary outcome measure was the Hamilton Anxiety Rating Scale (HAM-A), while secondary outcome measures included the Sheehan Disability Scale (SDS), the Clinical Global Impressions-Change Scale (CGI-C), and the Self-Report for the Assessment of Adjustment Disorders. Non-inferiority analysis was used to assess the primary outcome measure, and a multivariate logistic regression was employed to investigate predictors of response.ResultsTwo hundred and two adult outpatients with ADWA were enrolled at 17 primary care sites. One hundred and seventy seven patients completed the study (n = 87 in the etifoxine group; n = 90 in the alprazolam group). Etifoxine and alprazolam were accompanied by decreases in the HAM-A at day 28, with a difference between treatment groups in HAM-A score of 1.78 [90% CI; 0.23, 3.33] in favor of alprazolam. However, after medication discontinuation, HAM-A scores continued to improve in the etifoxine group, but increased in the alprazolam group; the difference between groups in mean change between day 28 and day 35 was significant (p = 0.019). Secondary outcome measures showed similar results for etifoxine and alprazolam at day 35. More treatment-related adverse events were reported in patients treated with alprazolam, particularly central nervous system-related AEs, and especially after medication discontinuation. No significant predictors of treatment response were found.ConclusionThis randomized controlled trial provides support for the efficacy and safety of etifoxine in the management of adjustment disorder with anxiety, particularly when treatment discontinuation data are also assessed. Etifoxine has the important clinical advantage of having anxiolytic effects, which are not being associated with dependence. Pharmacotherapy was equally efficacious in patients with more severe anxiety symptoms at baseline. Additional work using longer-term follow-up and collecting data on cost-efficiency of management options would further advance the field of ADWA.FundingSponsorship and article processing charges for this study were provided by Biocodex, Gentilly, France.
