Tag: Receptor pharmacology

First developed over a century ago, the organ bath is a foundational technique in pharmacology, serving as a critical tool for studying the effects of drugs and other stimuli on isolated tissues under carefully controlled conditions. It provides a bridge between molecular-level observations and whole-organism physiology.

In pharmacology, a vast majority of drugs operate by interacting with cellular receptors, broadly categorized as either agonists or antagonists. So, **what is an antagonist drug**? An antagonist is a substance that binds to a receptor but does not activate it, effectively blocking the action of other molecules.
