    Study Notes

    General Pharmacology

    • Pharmacology is the science focused on drugs, their properties, and their uses, aiming to develop more effective medicinal drugs.
    • General Pharmacology studies broad concepts of pharmacology, emphasizing pharmacokinetics and pharmacodynamics.

    Definitions of Key Terms

    • Clinical Pharmacology: Evaluates drug action, preferred administration routes, and safe dosage through clinical trials.
    • Drugs: Chemicals that alter living organism functions, used for diagnosis, prevention, control, or cure of diseases.
    • Pharmacy: The science of identifying, selecting, preserving, standardizing, compounding, and dispensing medical substances.
    • Pharmacodynamics: Studies the biological and therapeutic effects of drugs (“what the drug does to the body”).
    • Pharmacokinetics: Examines absorption, distribution, metabolism, and excretion (ADME) of drugs (“what the body does to the drug”).
    • Pharmacotherapeutics: Focuses on the appropriate selection and use of drugs for disease prevention and treatment.
    • Toxicology: The study of poisons and the harmful effects of drugs in excessive doses.
    • Chemotherapy: Effects of drugs on microorganisms, parasites, and cancer cells within living organisms.
    • Pharmacopeia: An official code listing established drugs and medical preparations along with descriptions of properties and tests.
    • Pharmacognosy: Identifies naturally occurring drug sources.
    • Posology: The study of drug dosages.

    Drug Potency and Efficacy

    • Potency: The lowest drug concentration required to produce the desired pharmacologic effects.
    • Efficacy: The highest drug concentration that achieves the desired pharmacologic effects.

    Drug Classifications

    • Drug Product: Finished dosage forms containing active ingredients.
    • Active Ingredients: Chemicals responsible for the drug product’s therapeutic effects.
    • Generic Drug: A drug whose patent has expired or was never patented.
    • Brand/Trade Name: A name given by a pharmaceutical company to differentiate its products.
    • Half-Life: Time for half of a drug to be eliminated; calculated as 0.693 divided by t₀.₅.

    Drug Reactions

    • Hypersensitivity/Hyperreactive: Usual effects occur at unexpectedly low doses.
    • Supersensitivity: Increased sensitivity due to denervation or allergy.
    • Hyporeactive: Usual effects require unexpectedly high doses.
    • Tolerance: Decreased sensitivity after prior exposure to drugs.
    • Idiosyncratic Reactions: Unexplainable reactions to drug administration.

    Types of Drugs for Ocular Diseases

    • Prophylactic Drugs: Prevent ocular diseases.
    • Diagnostic Drugs: Diagnose or detect ocular conditions.
    • Therapeutic Drugs: Treat ocular diseases; include curative, protective, and palliative uses.

    Pharmacokinetics Focus

    • Studies how the body interacts with drugs, covering routes of administration, absorption, and distribution.

    Prescription Components

    • Prescriber Details: Name, degree, address, and contact information.
    • Patient Information: Name, address, age, and date.
    • Superscription (℞): Indicates taking the medication.
    • Inscription: Medication name and strength.
    • Subscription: Directions to the dispenser about dosage forms.
    • Signal: Patient directions, often in English or Latin.
    • Prescriber’s Signature: Validation of the prescription.
    • Refill Directions: Information about allowable refills.
    • Other Information: Additional notes like “Dispense as Written.”

    Controlled Substances Classification

    • Schedule I (C-I): High abuse, no accepted medical use (e.g., Heroin, LSD).
    • Schedule II (C-II): High abuse, severe dependence potential (e.g., Morphine, Cocaine)—requires written prescriptions.
    • Schedule III (C-III): Moderate abuse potential (e.g., Codeine)—limited refills.
    • Schedule IV (C-IV): Low abuse potential (e.g., Diazepam)—refills allowed under certain conditions.

    Non-pharmacologic Management of Angina

    • Identify factors that exacerbate angina and address them.
    • Lifestyle changes include avoiding smoking, maintaining a healthy weight, and stress management.
    • Surgical options include coronary artery bypass and angioplasty.

    Drugs for Arrhythmia

    • Class I (Na+ Channel Blockers): Block sodium channels, preventing depolarization (e.g., Lidocaine, Procainamide).
    • Class II (Beta Blockers): Affect heart rhythm; include non-selective (e.g., Propranolol) and selective (e.g., Metoprolol).
    • Class III (Prolong Repolarization): Amiodarone is a key drug in this class.
    • Class IV (Calcium Channel Blockers): Verapamil and Diltiazem are preferred.

    Anti-infective Agents

    • Chemical substances can inhibit growth or kill microorganisms.
    • Antibiotics: Classified by mechanism of action (e.g., cell wall synthesis inhibitors like Penicillin).
    • Various classes target bacterial cell walls, membranes, genetic information, or essential metabolites.
