Summary

This study tests MK-4082, an experimental weight loss medicine taken as a pill, in healthy adults. Researchers want to see how the body processes MK-4082 when taken alone and when taken with diltiazem, a common heart medication. The goal is to understand any drug interactions and ensure safety before testing in people with higher body weight.
