Study Notes
Pharmacokinetics
- The general focus of pharmacokinetics is on the movement of drugs within the body, including absorption, distribution, metabolism, and elimination.
Drug Absorption
- The rate of drug absorption is largely determined by the rate of dissolution of the drug in the gastrointestinal tract.
Bioavailability
- Bioavailability refers to the extent to which the active drug ingredient becomes available to the target site in the body.
- It is a measure of the fraction of an administered dose of a drug that reaches the systemic circulation.
Drug Distribution
- Drug distribution refers to the dissemination of the drug throughout the body, including the movement of the drug from the systemic circulation into tissues and organs.
Route of Drug Administration
- The intravenous route is preferred for drug administration due to its sterility and convenience.
- This route allows for rapid and complete absorption of the drug, as it avoids the need for absorption from the gastrointestinal tract.
