Study Notes
Pharmacokinetics and Related Concepts
- Pharmacokinetics is not related to the ability of a substance to bind to a specific receptor.
Pharmacodynamics
- The term used to describe the ability of a substance to bind to a specific receptor is affinity.
Agonists
- Substances that have the same effect on the receptor as the endogenous ligand are called agonists.
Drug Transport Mechanisms
- Passive diffusion refers to the movement of substances across a cell membrane without the use of energy.
Metabolism
- Biotransformation refers to the process by which the body converts a substance into a more water-soluble form, typically for excretion.
