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.
