Pharmacologists practice a completely different job than pharmacists. Pharmacists may work in drug stores, convenience stores, pharmacies and grocery stores to dispense medication to patients with a prescription and offer them advice on side effects, how to take the medicine and what to expect.
Pharmacologists often may work for pharmaceutical companies that sell those drugs to the pharmacies around the world. The story is
Because the drugs and the organic molecules on which they act are microscopic, some of the resulting activity of medicine must be scrupulously analyzed under a microscope. Other chemicals can be analyzed in the patient’s blood, stool, urine, saliva or sweat. As the complex drug molecules are broken down by the body’s digestive system and metabolism, the resulting smaller molecules must do no harm to the person, or at least as little as possible. Pharmacologists also study the effects of drugs on the human liver, as it filters out toxins in the blood stream to keep them from accumulating in other parts of the body.
