Study Notes
Key Factors in Drug Absorption
- Factors influencing rate and efficiency: Solubility, formulation, route of administration, pH, presence of food, and blood flow.
- Driving force behind passive diffusion: Concentration gradient; drugs move from areas of higher concentration to lower concentration across cell membranes.
Pharmacokinetics
- Refers to the study of how the body absorbs, distributes, metabolizes, and excretes drugs. It describes the dynamics of drug movement throughout the body.
IV Drug Delivery
- Ensures rapid absorption and immediate bioavailability; bypasses first-pass metabolism, allowing drugs to enter systemic circulation directly.
Dependency of Drug Absorption
- Drug absorption is influenced by factors like drug formulation, route of administration, and physiological conditions of the gastrointestinal tract.

Description
Test your knowledge of pharmacokinetics, which involves assessing how drugs are absorbed, distributed, metabolized, and excreted by the body, and how these processes relate to the onset, duration, and intensity of drug effects.
