Study Notes
Drug Interactions
- A drug interaction occurs when a substance affects the activity of a drug, leading to an altered response or effect.
- A drug interaction can be defined as the modification of the effect of one drug by another drug or substance.
Causes of Drug Interactions
- Drug interactions can be caused by various factors, including pharmacokinetic interactions (absorption, distribution, metabolism, and excretion), pharmacodynamic interactions (effects on target receptors), and pharmaceutical interactions (excipients and formulation).
- Genetic variations, age, and underlying medical conditions can also contribute to drug interactions.
Pharmacodynamics
- The focus of pharmacodynamics is the study of the effects of drugs on the body.
- A consideration for a drug to interact with specific receptors is its affinity for the receptor and the binding capacity.
Drug Elimination
- A drug should be inactivated or excreted from the body at a reasonable rate to prevent accumulation and potential toxicity.
