Zonegran and Zelnorm drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Zonegran (zonisamide) and Zelnorm (tegaserod maleate). Common drug interactions include abdominal pain among females and alanine aminotransferase increased among males.

The phase IV clinical study analyzes what interactions people have when they take Zonegran and Zelnorm. It is created by eHealthMe based on reports of 25 people who take the same drugs from the FDA, and is updated regularly.
