5 Questions
What is the definition of pharmacology?
The study of drug action and mechanisms in living organisms
What is a drug?
A chemical substance that produces a biological effect when administered to a living organism
What are receptors?
Cellular macromolecules involved in specific chemical signaling between and within cells
What is the difference between agonists and antagonists?
Agonists activate receptors, while antagonists bind but do not produce a response
What is the Hill equation used for?
To describe the relationship between tissue response and agonist concentration
Study Notes
- Pharmacology is the study of drug action and mechanisms in living organisms.
- A drug is a chemical substance that produces a biological effect when administered to a living organism.
- Receptors are cellular macromolecules involved in specific chemical signaling between and within cells.
- Agonists activate receptors, while antagonists bind but do not produce a response.
- The Hill equation describes the relationship between issue response and agonist concentration.
- Potency can be measured using EC50, which compares the efficiency of one drug to elicit a response compared to another drug.
- Antagonists prevent agonists from acting on the receptor.
- Competitive antagonism occurs when agonists and antagonists compete for the same binding site.
- The dose ratio is the magnitude of the shift in the agonist concentration-response curve caused by a competitive antagonist.
- Drug toxicity and chemical carcinogenesis are important topics in pharmacology.
