Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Experimental groupExperimental Treatment2 Interventions
This subset of 12 individuals will complete all experimental study visits, and will ingest either 1) a placebo pill and placebo inhaler contents or 2) a cetirizine HCl pill (10 mg) and placebo inhaler contents in a randomized order and double-blind fashion.
Group II: Selection poolActive Control1 Intervention
Twenty-four total individuals will be recruited for the initial portion of the study, and the aforementioned 12 (6 men, 6 women) will be a subset of the initial 24. The other 12 participants will not take part in further study.
