简要总结
Compare the abuse liabilities of Staccato Alprazolam, oral immediate-release alprazolam, and Staccato Placebo.
详细描述
The Phase 1 clinical study compared the abuse liabilities of Staccato Alprazolam, oral immediate-release alprazolam, and Staccato Placebo in 14 subjects with a history of sedative abuse. Subjects who met the inclusion/exclusion criteria received 2 mg of oral alprazolam and matching placebo over 2 sessions. Those who demonstrated greater liking for alprazolam versus placebo were eligible to participate in the study.

盲法说明
In order to reduce discrimination between placebo and active Staccato Alprazolam, taste blinding will be accomplished using a rapidly dissolving, intensely flavored product (candy, strip or breath spray). The product will be administered immediately after each oral capsule dosing (at the -60-min and 0- min time points).

结局指标
主要结局
Response to EDQ Question Number 5, "Rate the Degree to Which You Would Like to Take the Drug Again"
时间窗: End of day for each of the 7 crossover treatments
The End of Day Questionnaire (EDQ) is a 7-question computerized instrument in which subjects rate the overall effect of the drug they received that day. The primary outcome measure for this trial is the categorical response to question number 5, "Rate the degree to which you would like to take the drug again", with a numerical value assigned to each of the responses allowed: 0=Not at all, 1=A little, 2=Moderately, 3=Quite a bit, 4=Very much
