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.
