Study Notes
Drug Definitions and Classifications
- Pharmacology is derived from Greek words meaning "medicine" and "study," denoting it as the study of medicine.
- Encompasses drug administration, bodily travel, and response mechanisms.
- Over 10,000 drugs available, each with unique therapeutic applications, interactions, side effects, and actions.
- Drugs may treat multiple diseases and elicit various effects based on individual factors (e.g., age, sex, genetics).
- Proper drug application can notably enhance quality of life, while improper use may lead to severe consequences.
- Nurses play a crucial role in patient drug management, education, and monitoring.
Therapeutics and Pharmacotherapy
- Therapeutics focuses on disease prevention and alleviating suffering using medical interventions.
- Pharmacotherapy refers to the clinical application of drugs for prevention and treatment of diseases.
Categories of Therapeutic Substances
- Drugs/Medications: Chemical agents with biological responses; termed "medication" post-administration.
- Biologics: Naturally sourced agents including hormones, monoclonal antibodies, blood products, and vaccines.
- Complementary and Alternative Medicine (CAM): Includes natural extracts, herbs, dietary supplements, and unconventional techniques (e.g., acupuncture, massage).
Sources of Drugs
-
Natural Sources: Include plants, animals, or inorganic compounds.
- Plants: Digitalis for cardiac issues, opiates for sedation.
- Animal Products: Insulin from pancreas of cows/pigs; thyroid drugs from animal tissues.
- Inorganic Compounds: Salts with therapeutic properties.
-
Synthetic Sources: Drugs developed through laboratory synthesis after testing natural compounds for therapeutic efficacy.
- Genetic engineering enables bacteria to produce therapeutic chemicals.
- Common synthetic drugs include Aspirin, Antidiabetics, Antihistamines, Paracetamol, and Thiazide Diuretics.
Impact of Drugs
- Correct drug use optimizes patient outcomes, while misapplication poses significant risks.
