Study Notes
Principles of Drugs (Medication)
- Medication—also known as therapeutic drugs—are medicines used in disease prevention or treatment.
- Therapeutic methods include drug/medication therapy, diet therapy, physiotherapy, psychological therapy, and aromatherapy.
- Drug/medication therapy uses medicines to treat illnesses.
- Diet therapy modifies diets, such as low-salt diets for cardiovascular diseases.
- Physiotherapy uses natural physical forces like water, light, and heat.
- Psychological therapy identifies and manages stressors.
- Aromatherapy uses essential oils for relaxation through massage.
Drug Names
- Chemical names describe the drug's chemical composition.
- Generic names are used before official drug-naming.
- Official names are used when the drug becomes formally recognized.
- Trade/brand names are registered names restricted to manufacturers (indicated by ®).
Example of Drug Names
- Chemical name: C24H27KN4O10S
- Generic name: Amoxicillin-potassium clavulanate acid
- Official name: Amoxicillin/clavulanic acid
- Brand name/trade name: Augmentin, Amoclan, Clavamox, Co-amoxiclav
Drug/Medication Classification
- Drugs are categorized by the body system influenced (e.g., nervous system, cardiovascular system).
- Classification is based on therapeutic use (e.g., antibiotics, diuretics).
- Classification also uses physiologic or chemical action (e.g., anticholinergic, beta-adrenergic blockers, calcium blockers).
- Drugs can be prescription or non-prescription, including over-the-counter medications.
- Some drugs or substances are illegal and used for purposes other than treatment.
Medication Actions & Interactions
- Drugs must reach target tissues at the appropriate concentration to affect the body.
- Agonists stimulate a response by interacting with specific receptors.
- Antagonists do not stimulate a response, instead interfering with receptor interaction.
- Pharmacokinetics describes how the body deals and distributes drugs; it determines appropriate blood levels.
- Pharmacokinetics is useful in determining dosing, administration routes, absorption, metabolism, and excretion.
- Pharmacodynamics studies how drugs act on the body, evaluating responses, including minimal and maximal.
- Pharmacodynamics depends on absorption, distribution (e.g., age/weight), metabolism rate, excretion, illness status, tolerance, and cumulative effects.
- Drugs do not create new bodily responses—they alter existing physiological activity—e.g., antihypertensive agents lower blood pressure; antipyretics lower temperature.
Drug Interactions
- Drugs, once taken, undergo stages of absorption, distribution, metabolism, and excretion.
- Drug interaction rates vary, and the actions of one drug can affect another at any interaction stage.
- Antiacids inhibit the absorption of antibiotics; caffeine with antihistamines increases central nervous system depression risk.
- Drugs interact through chemical bonds with receptor sites with similar shapes (key-and-lock).
- Drug molecules consist of diverse atoms and molecules, and strong drug affinity to a receptor leads to greater outcomes.
Nursing Responsibilities
- Nurses are accountable for their medication actions and decisions.
- Nurses must assess the drug's appropriateness, type, therapeutic indication, and correct dose.
- Nurses need to analyze the administration route based on the patient's conditions/physical status and allergies to avoid drug intolerance.
- Nurses verify and ensure the safety of the medication order.
- Medication administration follows principles of "right medication," "right patient," "right dose," "right time," "right route," "right education," and "right documentation."
- Nurses should respect patient rights to refuse a medication.
- Patients' conditions must be assessed prior to and after drug administration.
