What do you call those who study medicine?

Pharmacology:

1. The science of drugs, including their composition, uses, and effects.
2. The characteristics or properties of a drug, especially those that make it medically effective.

Just add "ist" to the "ologies" below to get the answer. For example - pathologist, etiologist, pathological physiologist etc.

The study of medicine is divided into four subjects:

I. Pathology: that part of medical science which studies disease.

A. Etiology: the investigation of morbific causes. B. Pathogeny: an explanation of the mode of action of causes-how cause produces the development of disease. C. Pathological Physiology: morbid reactions under disease-producing causes. D. Pathological Anatomy: which reveals the structural change resulting from disease. E. Symptomatology: which accounts for disturbances. F. Nosology: which describes and classifies disease.

II. Diagnosis: which determines the place where a given disease belongs in Nosology.

III. Prognosis: which foretells the outcome of disease.

IV. Therapeutics: which endeavors to relieve, modify, and cure disease.
