Study Notes

Pharmacodynamics is the study of how drugs interact with the body to produce their effects.

A drug's mechanism of action is an example of how a drug binds to a receptor or enzyme, leading to a specific response.

Patient factors, such as age, genetics, and health status, can influence the pharmacodynamic response to a drug.
Drug factors, such as potency, efficacy, and receptor specificity, can also influence the pharmacodynamic response.

Pharmacokinetics is the study of how the body absorbs, distributes, metabolizes, and eliminates drugs.

Patient factors, such as age, body composition, and organ function, can influence the pharmacokinetic properties of a drug.
Drug factors, such as solubility, lipophilicity, and dosing regimen, can also influence pharmacokinetics.

Bioavailability refers to the proportion of a drug that is absorbed and reaches the systemic circulation.
An example of a drug's bioavailability is the percentage of an oral dose that reaches the bloodstream.
