Detailed Description:
The planned study is a single dose, double-blind, double-dummy, active and placebo controlled, randomized, 4-period cross-over study investigating investigating 2 doses levels of Staccato Prochlorperazine, a positive control with known QT/QTc prolongation (oral moxifloxacin), and placebo.

  5. Subjects who are in good general health prior to study participation as determined by a detailed medical history, physical examination, 12-lead ECG, blood chemistry profile, hematology, urinalysis, and in the opinion of the Principal Investigator.
  6. Female participants (if of child-bearing potential and sexually active) and male participants (if sexually active with a partner of child-bearing potential) who agree to use a medically acceptable and effective birth control method throughout the study and for one week following the end of the study.
