Zileuton With or Without Celecoxib As Chemopreventive Agents in Smokers

Completed · Phase 1/Phase 2

Conditions studied: Tobacco Use Disorder

In brief

The goal of this clinical research study is to learn how zileuton alone or the combination of zileuton and celecoxib may affect certain chemicals in the body that may be linked with a risk for smoking-related lung disease. These effects will be measured by a urine test
