Definition
Agonists are substances that stimulate receptor activity, mimicking the effects of neurotransmitters, while antagonists block or inhibit receptor activity, preventing those effects. Together, they play essential roles in understanding drug interactions and neurotransmitter function in the brain.
Summary
Agonists and antagonists are fundamental concepts in pharmacology that describe how drugs interact with receptors in the body. Agonists activate receptors to produce desired biological responses, while antagonists block these receptors, preventing any response. Understanding these interactions is crucial for developing effective medications and treatment plans. In clinical practice, agonists are often used to relieve pain or manage conditions like asthma, while antagonists can reverse overdoses or block unwanted effects. By studying agonists and antagonists, healthcare professionals can better understand drug actions and improve patient outcomes.
