Lopressor and Nystop drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Lopressor (metoprolol tartrate) and Nystop (nystatin). Common drug interactions include chronic kidney disease among females and sepsis among males.

The phase IV clinical study analyzes what interactions people have when they take Lopressor and Nystop. It is created by eHealthMe based on reports of 28 people who take the same drugs from the FDA, and is updated regularly.

How the study uses the data?

The study uses data from the FDA. It is based on metoprolol tartrate and nystatin (the active ingredients of Lopressor and Nystop, respectively), and Lopressor and Nystop (the brand names). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered. Dosage of drugs is not considered in the study.

How to use the study?
