Study Notes
Drug Absorption and Bioavailability
- The most important factor in drug absorption is the lipid solubility of the drug.
Factors Affecting Lipid Solubility
- Drugs that are likely to be lipid soluble and non-ionized in an acidic medium are weak bases.
Pharmacology Branches
- Pharmacokinetics is the branch of pharmacology that deals with the effect of the body on drugs.
Bioavailability
- A decrease in first-pass metabolism increases bioavailability.
- The bioavailability of a drug given via the intravenous (IV) route is 100%.
