  • Body Mass Index (BMI) in the range of 18 to 30 kg/m2
  • Female subjects of childbearing potential must be using a medically acceptable form of birth control for at least 1 month prior to screening (3 months on oral contraceptives), e.g., oral or patch contraceptives, intrauterine device, injectable contraceptive (e.g. Depo-Provera®), or a double barrier and have a negative pregnancy test at Screening and prior to IMP administration on Day 1 and Day 7 ± 1 day. Female subjects of non-childbearing potential must be amenorrheic for at least two years or had a hysterectomy and/or bilateral oophorectomy

Exclusion Criteria:

These may include thyroid disease (e.g., hyperthyroidism, hypothyroidism), uncontrolled diabetes mellitus, coronary heart disease, ischemic heart disease , symptomatic prostatic hypertrophy, bladder neck obstruction, hepatic insufficiency, narrow-angle glaucoma, pyloroduodenal obstruction, or stenosing peptic ulcer;
  • Known allergy to chlorpheniramine, dexchlorpheniramine, or any of its inactive ingredients
  • Self-reported non-responders (lack of therapeutic effect) to antihistamines
  • Administration of epinephrine is contra-indicated;
  • Current use of oral steroids, including prednisone and prednisolone;
  • Females who are pregnant or lactating
  • A history of anaphylaxis to ragweed allergen
  • Subjects with a history of asthma, lower respiratory tract disease, emphysema or chronic bronchitis; At the discretion of the investigator, subjects with self-reported mild intermittent asthma or exercise induced asthma may be included.
