We’ll explore both informational aspects and practical considerations to help you make informed decisions about why use a medical sales liaison in your business strategy.
Defining a “Medical Sales Liaison”
A medical sales liaison—often called a Medical Science Liaison (MSL)—is a field-based medical affairs expert specializing in peer-to-peer scientific exchange with healthcare professionals and KOLs. These specialists represent a distinct category of medical professionals who work for pharmaceutical, biotechnology, medical device, or other healthcare companies.
Unlike conventional pharmaceutical representatives, medical liaisons prioritize scientific accuracy and balanced information exchange rather than direct product promotion. They serve as credible resources who can discuss complex medical concepts, research findings, and clinical applications with healthcare practitioners.
The fundamental differences between medical sales liaisons and traditional sales representatives include:
- Focus: Medical liaisons concentrate on unbiased scientific education rather than quota-driven sales pitches
- Mission: Their primary purpose is gathering clinical insights to inform company strategy versus pushing product adoption
- Credentials: Most liaisons hold advanced degrees (PharmD, PhD, MD) and possess deep therapeutic expertise
- Relationships: They build long-term scientific partnerships rather than transactional sales interactions
- Communication style: Peer-to-peer scientific discussions versus promotional messaging
