Study Notes
Pharmacodynamics
- The main focus of pharmacodynamics is the study of the effects of drugs on the body.
Drug Effects on the Body
- Most drugs exert their effects on the body by binding to specific receptors.
- This binding causes a conformational change in the receptor, triggering a response.
Drug-Receptor Complex
- The formation of a drug-receptor complex initiates a signaling cascade, leading to a physiological response.
Signal Transduction
- Drugs act as ligands, binding to receptors to initiate signal transduction pathways.
- Receptors play a crucial role in signal transduction, transmitting the signal from the drug-receptor complex to the intracellular environment.
