Study Notes
Drug Basics
- A drug is any substance that causes a change in a person's physical or psychological state.
- A medicine is a drug used to cure, prevent, or treat illness with three key qualities: effectiveness, safety, and minor or minimal side effects.
Medication Administration
- A prescription is a written order from a doctor for a specific medicine and amount.
- Over-the-counter (OTC) medicines can be purchased without a prescription and are sold on store and pharmacy shelves.
How Drugs Enter the Body
- Implantable pump (e.g., insulin pump)
- Inhalation (through blood vessels in the lungs)
- Injection (through a needle)
- Transdermal (through a patch)
- Ingestion (swallowed)
- Topical (applied and absorbed through the skin, e.g., medicated cream)
Drug Effects and Consequences
- Tolerance: cells of the body adapt, requiring more of the drug to feel original effects.
- Dependence: drug must be present in the system at all times for daily functioning, leading to withdrawal symptoms upon cessation.
- Addiction: a condition where the brain's reward system drives continued substance use, leading to loss of control and physical and psychological dependence.
- Drug Abuse: using a drug for no medical reason.
- Drug Misuse: medically using a drug but taking the wrong amount, skipping days, or using the wrong method of intake.
