Phase 1
Completed
Conditions
Smoking, Cigarette
Interventions
Registration Number
NCT00873769
Lead Sponsor
Alexza Pharmaceuticals, Inc.
Brief Summary

The objective of this trial was to assess the pharmacokinetics of a single dose of 10 mg Staccato Loxapine administered to smokers compared to nonsmokers.

Detailed Description

Pharmacokinetics and sedation pharmacodynamics were studied using a visual analog scale were studied in male and female adult subjects (nonsmokers and smokers) following a single dose of 10 mg of inhaled loxapine. Blood samples were drawn at predose, 30 seconds, 1, 2, 3, 10, 30, and 60 minutes, and 2, 6, 12, and 24 hours after dosing. Loxapine and 8-OH-loxapine were analyzed using reverse-phase liquid chromatography coupled with a tandem mass spectrometer.
