Study Notes
Drug Administration
- Oral: Swallowing medication in tablet, capsule, or liquid form.
- Intravenous (IV): Injecting medication directly into a vein for immediate absorption.
- Intramuscular (IM): Injecting medication into a muscle, allowing slow absorption.
- Subcutaneous (SC): Injecting medication beneath the skin for slower absorption.
- Topical: Applying medication directly to the skin.
- Inhalation: Breathing in medication through the nose or mouth.
Drug Absorption Factors
- Route of administration: The way the drug enters the body greatly impacts absorption.
- Solubility: Whether a drug dissolves in water or lipids influences its movement across cell membranes.
- Blood flow: Higher blood flow to the administration site promotes faster absorption.
- Surface area: Larger surface areas for absorption enhance drug entry into the body.
- Food intake: Food can affect stomach pH and delay absorption.
Drug Concentration Terminology
- Peak plasma concentration (Cmax): The highest concentration of a drug in the blood after administration.
Liver's Role in Drug Metabolism
- Biotransformation: The liver breaks down drugs into inactive metabolites, making them easier to eliminate.
Drug Interactions
- Synergism: Two drugs working together to produce a greater effect than the sum of their individual effects.
