Alleviation of Upper Respiratory Inflammation and Associated Common Cold Symptoms
In Brief
A Phase 1 clinical trial evaluating Wintergreen Throat Spray and Aspirin Tablet, Aspirin Throat Spray and Placebo Tablet, and 2 other interventions for Common Cold and 11 related conditions. Completed, enrolled 157 participants across 6 sites.
Detailed Summary
Upper respiratory infections (URIs) have long posed a significant burden to the US healthcare system. Well before the coronavirus disease of 2019 (COVID-19) pandemic they have been among the most common acute outpatient illnesses, causing 75-100 million physician visits each year on average, and costing the health care system billions of dollars annually. This double-blind randomized placebo-controlled study tested the efficacy of two anti-inflammatory throat sprays against placebo and against a throat spray taken in conjunction with 325mg of aspirin, a well-known systemically administered cyclooxygenase (COX) inhibitor. Participants having common cold symptoms lasting less than two days were enrolled and given treatment to administer at home. Various common cold symptoms were assessed and measured via clinically validated self-assessment scales. Participants were screened for influenza and COVID-19 before enrollment and were excluded if found positive.
