          -  On Focused Nasal Examination, the presence of any nasal mucosal erosion, nasal
             ulceration, or nasal septal perforation at either the screening visit or randomization
             visit will disqualify the subject from the study.

          -  Other nasal disease(s) likely to affect deposition of intranasal medication, such as
             sinusitis, rhinitis medicamentosa, clinically significant polyposis, or nasal
             structural abnormalities.

          -  Nasal surgery or sinus surgery within the previous year.

          -  Chronic sinusitis - more than 3 episodes per year

          -  Planned travel outside of the study area during the study period

          -  The use of any investigational drug within 30 days prior to Screening. No
             investigational products are permitted for use during the conduct of this study

          -  Presence of any hypersensitivity to drugs similar to azelastine and to either sorbitol
             or sucralose (Splenda® brand sweetener)

          -  Existence of any surgical or medical condition or physical or laboratory findings,
             which in the opinion of the investigator or sponsor's medical monitor, might
             significantly alter the absorption, distribution, metabolism, or excretion of study
             drug; that might significantly affect the subject's ability to complete this trial; or
             their safety in this trial.

          -  Clinically relevant abnormal physical findings which, in the opinion of the
             investigator, would interfere with the objectives of the study or that may preclude
             compliance with the study procedures
