Zantac and Hydroxyurea drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Zantac (ranitidine hydrochloride) and Hydroxyurea (hydroxyurea). Common drug interactions include ecchymosis among females and hepatic failure among males.

The phase IV clinical study analyzes what interactions people have when they take Zantac and Hydroxyurea. It is created by eHealthMe based on reports of 83 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 ranitidine hydrochloride and hydroxyurea (the active ingredients of Zantac and Hydroxyurea, respectively), and Zantac and Hydroxyurea (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?
