Ampyra and Dupuytren's contracture - a phase IV clinical study of FDA data


Dupuytren's contracture is reported only by a few people who take Ampyra.

The phase IV clinical study analyzes which people take Ampyra and have Dupuytren's contracture. It is created by eHealthMe based on reports of 72,990 people who have side effects while taking Ampyra from the FDA, and is updated regularly.

With medical big data and AI algorithms, eHealthMe enables everyone to run phase IV clinical trial to detect adverse drug outcomes and monitor effectiveness. Our original studies have been referenced on 600+ peer-reviewed medical publications including The Lancet, Mayo Clinic Proceedings, and Nature. Most recently, phase IV clinial trails for COVID 19 vaccines have been added, check here.
