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


Dupuytren's contracture is reported only by a few people who take Nitro-Bid.

The phase IV clinical study analyzes which people take Nitro-bid and have Dupuytren's contracture. It is created by eHealthMe based on reports of 615 people who have side effects while taking Nitro-bid from the FDA, and is updated regularly.

Phase IV trials are used to detect adverse drug outcomes and monitor drug effectiveness in the real world. With medical big data and AI algorithms, eHealthMe is running millions of phase IV trials and makes the results available to the public. Our original studies have been referenced on 600+ medical publications including The Lancet, Mayo Clinic Proceedings, and Nature.
