A pharmacology student asks the instructor what an accurate description of a drug agonist is. A drug that interacts directly with receptor sites to cause the same activity that a natural chemical would cause at that site is a drug agonist.
<h3>What is pharmacology?</h3>
Pharmacology is the discipline of medicine, biology, and pharmaceutical sciences that studies how drugs or medications work.
The two main subfields of pharmacology are: The term "pharmacokinetics" describes how medications are absorbed, distributed, metabolized, and excreted. Drug molecular, biochemical, and physiological effects, including drug mode of action, are referred to as pharmacodynamics.
The study of medications in humans using pharmacological concepts and methodologies is known as clinical pharmacology. Posology, the study of drug dosage, serves as an illustration of this. Toxicology and pharmacology have a close relationship.
