Study Notes
Introduction to Pharmacology
- Pharmacology studies drugs and their effects on living systems, including biochemical and physiological impacts.
- Pharmacotherapeutics involves using drugs for diagnosis, prevention, and treatment of diseases, including pregnancy prevention.
Common Drugs and Risks
- Aspirin can be harmful to children under 16, leading to Reye's syndrome, characterized by acute inflammatory encephalitis and fatty liver.
- Middle-aged and elderly individuals often take aspirin to prevent cardiovascular diseases by affecting clotting factors, acting as an anti-platelet drug.
Key Terminologies in Pharmacology
- Pharmacognosy: Study of drugs derived from natural sources, such as plants and animals (e.g., Papaver Somniferum).
- Pharmacopoeia: Reference summarizing drug purity, strength, and synthesis directions.
- Pharmaceutics: Science of drug preparation and dispensing.
Drug Response and Individual Sensitivity
- Pharmacodynamics: Examines what drugs do to the body, including desired and adverse effects.
- Pharmacokinetics: Focuses on drug movement, distribution, and the rate at which these processes occur.
Drug Tolerance and Adverse Reactions
- Drug tolerance refers to decreased responsiveness over time, impacting pain relief and therapeutic effects.
- Adverse reactions can be severe, possibly leading to conditions like anaphylaxis, a critical allergic reaction involving extensive histamine release.
Medication and Prescriptions
- Medications are substances administered post-drug administration, aimed at delivering therapeutic effects.
- Medical prescriptions (Rx) provide written directions for medication use, ensuring proper dosage and treatment guidance.
Side Effects and Allergic Reactions
- Side effects are physiological effects unrelated to the intended drug effects, often unintended and secondary.
- Allergic reactions involve hypersensitivity to foreign substances (allergens), which may escalate to anaphylaxis.
