We’ve devoted more than 60 years of research to cardiovascular diseases. Much of our research has focused on identifying new medicines for hypertension (high blood pressure) and many other cardiovascular (heart and blood vessel) conditions.

Medicine for the people, driven by research
Merck stands at the forefront of research to help prevent and treat diseases that threaten people’s health, by conducting clinical trialsClinical Study / Clinical TrialA research study designed to learn how our bodies respond to medicines, vaccines or other treatments; A way to study new medicines (vaccines), devices and treatments to see if they are safe and work in people; Compares a study treatment to another treatment or even no treatment (placebo).

Have you ever wondered how an investigational medicine or vaccine goes from a concept to an approved medication? It’s a fascinating journey that includes numerous steps and phases. And the pivotal aspect of this journey? Volunteers like yourself!

Our long-standing history in medical science
We’ve spent the past 130 years focused on research and innovation to help save and improve lives. With global reach and science-driven research, we’re maintaining our dedication to continue in the pursuit of better health.


Diversity in our clinical trial research
Different people may have different reactions to the same treatment, based on their age, gender, weight, race, ethnicity, and other factors. Clinical trials rely on volunteers to take part, and it’s vital that these volunteers come from diverse backgrounds. By including people from diverse backgrounds, clinical trials can show if the treatments are safe and work well for people from all different communities.
Resources for patients and caregivers
Whether you’re a patient or a caregiver, use these resources to learn if you or your loved one may be eligible to take part in a clinical trial.
