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.
