What is a Medical Science Liaison(MSL)?

The MSL is a field-based therapeutic specialist employed by pharmaceutical and medical device companies. Usually MSLs are organized under the medical affairs unit which are responsible for scientific exchanges with the clinical community.

The primary purpose of the MSL role is: 
  • To act as a liaison to exchange therapeutic information between the Medical community in the therapeutic Area  in which they work (i.e. Cardiology, Diabetology, Oncology etc) and the company.
  • Most important function of MSL role remains to establish and maintain peer to peer relationships with Key Opinion Leaders (KOL's) in their therapeutic areas.
  • To be scientific or disease state experts for internal colleagues (sales and marketing)  

The role of Medical Science Liaison may be referred by some other names like Medical Advisor, Medical Affairs Manager and Medico Marketing Manager. Usually they are all the same, but in some companies the reporting structure may vary with the name of the role. There may be a singular reporting just to the Medical Affairs function or a dual reporting to both Medical Affairs and Marketing function. A singular reporting structure is always more comfortable to work with.

The role can be target driven or non target driven. Ideally a non targeted approach is the right approach and a ethical one also; since the job involves interaction of two medical professionals for exchange of genuine unbiased scientific information and not just an opportunistic approach to generate sales.

  2. I'm biologist in italy and I'm msl for a US big pharma. Before now I was a rep for the same company. Here we don't pay the KOLs and they're quite easy to meet. For more interesting information click here.

  3. The role of MSL is SUPPOSED to be identical across the globe, however in India, there are significant obstacles; Scientific exchange is minimal due to lack of ongoing research, and duties such as organizing Investigator Initiated Trials are non-existent. Another difference (as noted in this article) is that the base qualification is equivalent to possessing an M.D. (i.e., M.B.B.S.), while in NA and Europe, many Ph.D.s are able to ably fill the role. This difference is likely a product of the Ph.D. system not being as prevalent in India (relatively) + the emphasis on knowledge that only medical training would provide -- a by-product of the lack of fundamental science-related research, which would ostensibly be discussed by a Ph.D. level MSL. Overall, it's doctors talking to much more senior doctors, and most of the time getting very little in the way of collegial respect. India is a different market, thus the vast differences. Word of warning -- your daily routine will resemble a glorified sales rep. Get ready to wait for hours (with said sales reps) to see a KOL. Not to say it's not an interesting role - just a departure from its Western counterpart. (Samuel seems to allude to that.)

  4. the role of HR is to plan for the roles that the company needs- to identify talent and provide the resources necessary to help people develop.

    success with good planning
