    Study Notes

    Introduction to Pharmacology

    • Pharmacology studies the effects of drugs on living organisms.
    • It focuses on how drugs interact with biological systems and influence normal and abnormal bodily processes.

    Branches of Pharmacology

    • Pharmacodynamics: investigates how drugs affect living organisms, focusing on their chemical and physiological effects.
    • Pharmacokinetics: studies how the body processes drugs: absorption, distribution, metabolism, and excretion.

    Key Concepts in Pharmacology

    • Drug: Any substance used to diagnose, treat, or prevent disease.
    • Drug Names: Drugs have multiple names:
      • Chemical name: Describes chemical structure.
      • Generic name: Non-proprietary name, used by all manufacturers.
      • Brand name: Proprietary name, assigned by the manufacturer.
    • Drug Sources: Drugs originate from various sources:
      • Natural sources: Plants, animals.
      • Synthetic sources: Created in labs.
      • Semi-synthetic sources: Modified natural substances.
    • Physical and Chemical Properties: These properties determine a drug's:
      • Solubility: Ability to dissolve in a solvent.
      • Stability: Resistance to decomposition.
      • Route of administration: How it enters the body.

    Pharmacokinetics: How the Body Handles Drugs

    • ADME: The four main processes influencing drug action:
      • Absorption: How drugs enter the bloodstream.
      • Distribution: How drugs spread throughout the body.
      • Metabolism: How drugs are broken down.
      • Excretion: How drugs are eliminated from the body.
    • Rate of Kinetics: Describes the speed of drug processes, such as absorption, metabolism, and excretion in different tissues and organs.

    Drug Properties and Effects

    • Receptor: A specific molecule on a cell surface that binds to a drug, triggering a response.
    • Dose-response Relationship: The relationship between the amount of drug taken and the effect it produces.
    • Potency: The amount of drug needed to create a specific effect.
    • Efficacy: The maximum effect a drug can produce.
    • Toxicology: The study of harmful drug effects on the body.
    • Side Effects: Unwanted effects of drugs that occur at normal therapeutic doses.

    Drug Interactions and Steady State

    • Drug Interactions: The combined effect of multiple drugs or interactions with other substances (food, alcohol) in the body.
    • Steady State: The point where the amount of drug in the body remains constant despite ongoing administration. This is achieved when the rate of drug administration equals the rate of drug elimination.

    History of Pharmacology

    • Ancient Egypt: Medicinal plant use documented on papyri.
    • Ancient Greece: Hippocrates emphasized observation and experimentation in medicine.
    • Ancient Rome: Dioscorides wrote "De Materia Medica," a foundational text on pharmacy.
    • Middle Ages: Monasteries preserved and developed knowledge of medicinal plants.
    • Renaissance: Paracelsus and Vesalius advanced pharmacy.
    • 18th and 19th Centuries: Isolation of active ingredients and development of pharmacopoeias established pharmacy as a distinct discipline.
    • 20th Century: Advances in biochemistry, pharmacokinetics, and pharmacodynamics led to drug standards and measuring systems.

    Key Discoveries in Pharmacology

    • Smallpox Vaccination: Developed by Edward Jenner in the 18th century.
    • Penicillin: Discovered by Sir Alexander Fleming in 1928, first used for treating ophthalmia by Cecil George Paine in 1930.
    • Streptomycin: Discovered by Selman Abraham Waksman.
    • Cocaine: Introduced as a local anesthetic for eye surgery by Karl Koller.
    • Aspirin: Derived from Salicylic acid.

    Margaret Sanger

    • Advocate for birth control and sex education.
    • Popularized the term "birth control."
    • Founded Planned Parenthood.
    • Published writings on family limitation.
    • Faced legal challenges for her work.
