Secondary Outcome Measures :
  1. Nasal Spray Attributes Questionnaire score [ Time Frame: from baseline through study completion, an average of 40 days ]
    based on a scale of 0 to 6, for each immediate attribute assessed; 0 equals none, 3 equals severe for each question; lower scores have better outcome

  2. Incidence and severity of AE (bronchospasms) [ Time Frame: from baseline through study completion, an average of 40 days ]
    AE monitoring

Criteria

Inclusion Criteria:

Must have given written informed consent before any study-related activities are carried out and must be able to understand the full nature and purpose of the trial, including possible risks and adverse effects 2. Adult males and females, 18 to 64 years of age (inclusive) at the screening visit 3. Are non-smokers (including tobacco, e-cigarettes and marijuana) for a minimum of 1 month prior to the screening visit. Non-smokers with a significant history of smoking (> 5 pack years) are not eligible 4. Have a physically normal nasal structure (minor septum deviation allowable) 5. Body mass index (BMI) (calculated) within the range of 18 to 30 kg/m2 inclusive at the screening visit and prior to dosing on Day 1 6. Medically healthy without clinically significant abnormalities in the opinion of the investigator at the screening visit and prior to dosing on Day 1, including:

  1. Physical examination without any clinically significant findings
  2. Systolic blood pressure (BP) in the range of 90 to 140 mm Hg (inclusive) and diastolic BP in the range of 50 to 90 mm Hg (inclusive) after at least 5 minutes in a seated position
