Drug Samples and Physician Prescribing

by Rich Hoeckh, HNE Clinical Pharmacist

  • In the United States, drug companies handed out the retail equivalent of $16 billion in free drug samples in 2004.
  • In the US, the number of pharmaceutical sales representatives (reps) has increased from 38,000 in 1995 to 100,000 in 2005. In the US as of 2004, there is approximately one rep for every 2.5 physicians.1

Drug companies spend about $25 billion per year in the US – promoting their products through a combination of direct-to-consumer (DTC) ads, supporting rep activities, and handing out drug samples. The practice of visiting physicians by reps in order to promote the company’s drugs is called detailing. Free drug samples given out during detailing visits account for $16 billion out of the $25 billion spent annually on drug marketing and promotion.

When a rep gives a physician office samples as a form of marketing, how does it influence prescribing behavior?

A recent study published  in The American Journal of Medicine  looked at the practice of sampling and came up with some interesting conclusions.  The results of the study suggest that when samples were available, resident physicians were less likely to choose unadvertised or over-the-counter drugs.  The researchers noted “a trend toward less use of inexpensive drugs.”  The study went on to conclude that “access to drug samples influences resident prescribing practices,” and that this “could affect resident education and increase drug costs for patients.” 2
