Summary
This study seeks to determine whether a simple, single intervention of Cetirizine / Zyrtec® use can improve exercise performance of active individuals when acutely exposed to altitude. For this project, healthy subjects will perform steady state and progressive work rate exercise, endurance performance time trials, and repeated sprint performance time trials in the laboratory at a simulated altitude of 3000m (9900ft) after dosing with 10 mg of Cetirizine or a placebo in a repeated measures design.

Criteria
Inclusion Criteria:

- Physically active a minimum of 120 minutes a week, as determined by questionnaire

- 18-35 years of age

- Classified as low risk, based on the modified PAR-Q questionnaire, BMI, and
non-smoking status

- No history of pulmonary disease and pulmonary function classified as normal, as
defined by the following measurements being 80% of predicted values: forced vital
capacity (FVC), forced expired volume in one second (FEV1) and FEV1/FVC, according to
the American Thoracic Society standards.

Exclusion Criteria:

- Current smoker

- Women who are pregnant or could possibly be pregnant

- BMI > 25 kg/m2

- History of pulmonary disease or <80% of predicted FCV, FEV1 and/or FEV1/FVC.

- A history of renal or liver disease, due to possible interaction effect with
Cetirizine

- Currently taking any prescription or over the counter medications for the treatment of
allergies, or taking any of the below listed drugs known to have a moderate or higher
interaction effect with Cetirizine:

isocarboxazid tranylcypromine bosutinib clobazam crizotinib daclatasvir eliglustat
hyaluronidase lomitapide lurasidone ombitasvir/paritaprevir/ritonavir phenelzine ponatinib
