Should Sales Reps for Compounded Drugs be Paid a Salary or a Commission? Should This Be a Factor that the FDA and State Boards of Pharmacy Consider?

In running across a recent advertisement for a job for veterinary compounding pharmacy in Texas as a pharmaceutical sales representative, I observed that the job was based on a commission like other pharmaceutical sales jobs.  A friend in the business and I then had a discussion about whether these jobs, pharmaceutical sales representative jobs for compounding pharmacies, should be commission or salary.  The friend is probably one of the few in the industry who is paid a salary for his work as a pharmaceutical sales representative for a compounding pharmacy.  He strongly believes that this is the correct position and that if one is paid a commission for this type of work it indicates that the pharmacy is manufacturing because compounded drugs for both humans and animals are suppose to be patient-specific and not produced in mass-quantities.  If one is being paid a commission does this indicate the company is manufacturing instead of producing patient-specific compounds?  Should this be a factor that the FDA and the state boards of pharmacy examine?  How many sales representatives for compounding pharmacies are paid a salary instead of a commission? I am interested in what readers have to say about this issue.  Readers please comment.
