The Food and Drug Administration (Fda) employs a small army of Pharmacologists to evaluate data used to support IND or NDAs for drugs on their way to being marketed. Pharmaceutical companies' research and development divisions employ numerous pharmacologists, both non-clinical and clinical, both to conduct research prior to approval of a drug and afterwards, to monitor safety and discover/develop new applications.
A Pharmacologist does not work with tablets, pills, or directly fulfilling consumer/patient needs. A Pharmacologist is not qualified to advise patients concerning the medications they use (although a Pharmacologist may have good suggestions what patients should discuss with those responsible for their healthcare).
A Pharmacologist is not a Healthcare Professional.
