Study Notes
Pharmacodynamics
- Pharmacodynamics studies how drugs interact with the body and receptors.
- A drug molecule binds to specific receptors depending on the function of the cell it alters.
Drug Types
- Agonist: produces the desired physiological response after binding with a receptor, resulting in a maximal physiological response.
- Partial Agonist: binds to the receptor site, reducing the response and the effects of other similar agonists, resulting in a sub-maximal response.
- Antagonist: administered to stop or reduce the physiological response to an agonist, without producing a response itself.
Antagonist Subtypes
- Competitive Antagonist: binds temporarily or reversibly, can be overpowered and removed from the receptors if the agonist increases.
- Non-Competitive Antagonist: binds irreversibly to a site of action, remaining in the receptors regardless of the amount of agonist administered.
