Flolan and Ranitidine drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Flolan (epoprostenol sodium) and Ranitidine (ranitidine). Common drug interactions include hypovolaemia among females and pain in jaw among males.

The phase IV clinical study analyzes what interactions people have when they take Flolan and Ranitidine. It is created by eHealthMe based on reports of 27 people who take the same drugs from the FDA, and is updated regularly.

What is Flolan?

Flolan has active ingredients of epoprostenol sodium. eHealthMe is studying from 10,067 Flolan users. Check the latest studies of Flolan.

What is Ranitidine?

Ranitidine has active ingredients of ranitidine. It is often used in gastroesophageal reflux disease. eHealthMe is studying from 234,475 Ranitidine users. Check the latest studies of Ranitidine.

How the study uses the data?

The study uses data from the FDA. It is based on epoprostenol sodium and ranitidine (the active ingredients of Flolan and Ranitidine, respectively), and Flolan and Ranitidine (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?
