Adenoscan and Pulse absent - a phase IV clinical study of FDA data


Pulse absent is found among people who take Adenoscan, especially for people who are female, 60+ old, have been taking the drug for < 1 month.

The phase IV clinical study analyzes which people take Adenoscan and have Pulse absent. It is created by eHealthMe based on reports of 480 people who have side effects when taking Adenoscan from the FDA, and is updated regularly. You can use the study as a second opinion to make health care decisions.

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.
