Apresoline and Procardia drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Apresoline (hydralazine hydrochloride) and Procardia (nifedipine). Common drug interactions include cough among females and cardiac failure congestive among males.

The phase IV clinical study analyzes what interactions people have when they take Apresoline and Procardia. It is created by eHealthMe based on reports of 72 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 hydralazine hydrochloride and nifedipine (the active ingredients of Apresoline and Procardia, respectively), and Apresoline and Procardia (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.
