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

Summary:

Drug interactions are reported among people who take Cordarone (amiodarone hydrochloride) and Apresoline (hydralazine hydrochloride). Common drug interactions include weight decreased among females and cardiac failure congestive among males.

The phase IV clinical study analyzes what interactions people have when they take Cordarone and Apresoline. It is created by eHealthMe based on reports of 23 people who take the same drugs from the FDA, and is updated regularly.
