Evaluation of Anti-inflammatories in the Reduction of Bite Reactions
Evaluation of Topical Ibuprofen and Steroid in the Reduction of Local Reactions and Symptoms From an Aedes Aegypti Mosquito Bite
The purpose of this study is to evaluate two separate antiinflammatory products for the relief of symptoms through suppression of the immunological and inflammatory response following a mosquito bite. The investigators have selected ibuprofen gel as a NSAI formulation and 0.05% Clobetasone butyrate as a steroid cream with their appropriate physical matched placebo products.
