What is Medical Affairs?
Medical Affairs is a specialized team in pharmaceutical and biotech companies that connects scientific research with real-world medical practice. They do not promote or sell drugs. Instead, they ensure that doctors, healthcare providers, and patients understand how medicines work, how safe they are, and how they can help patients.
Where this happens:
- In hospitals and clinics, when MSLs meet doctors and KOLs
- At conferences and workshops organized by the company
- Through medical information portals or email responses to HCP queries
- Within the company, providing insights from the field to R&D and strategy teams
Example: Imagine your doctor is trying to decide the best treatment for a patient. There are tons of research and new studies coming out all the time and it’s overwhelming! Medical Affairs steps in like a guide or translator, helping the doctor understand the latest evidence so the patient gets the right treatment.
