Study Notes

Objectives of Pharmacy Course

  • Understand dosage forms and routes of administration.
  • Explain prescription parts and labelling for compounding.
  • Recall Latin numerals and abbreviations in prescriptions.
  • Recognize conversions between metric and imperial systems.
  • Understand basic pharmaceutical calculations, including % concentration and molarity.
  • Describe extemporaneous preparation procedures.
  • Define ADME and analyze potential pharmaceutical incompatibilities.

Introduction to Dosage Forms

  • Pharmaceutics: The study of dosage form design influenced by physical, chemical, and biological factors.
  • Dosage form: The presentation format of the drug to patients, characterized by unique physical and pharmaceutical features.

Key Terminology

  • Dose of a drug: Expected amount to produce medicinal effects in adults.
  • Dosage regimen: Schedule or manner of drug administration (e.g., three times daily).

Importance of Dosage Forms

  • Ensures safe and convenient delivery of accurate dosages.
  • Protects drugs from atmospheric oxygen and moisture (e.g., coated tablets).
  • Shields drugs from gastric acid after oral intake.
  • Conceals unpleasant tastes and odors of drugs (e.g., syrup, capsules).

Characteristics of Dosage Forms

  • Depends on drug solubility:
    • Solutions for soluble substances.
    • Suspensions for insoluble compounds.
  • Enables controlled drug release mechanisms for extended action (e.g., controlled-release tablets).
  • Facilitates optimal drug action via topical, rectal, or inhalation routes.

Classification of Dosage Forms

  • Liquid Dosage Forms:

    • Solutions: Homogeneous mixtures of solute in solvent.
    • Colloids (Dispersion)
    • Suspensions
    • Emulsions
  • Semisolid Dosage Forms:

    • Ointments, creams, pastes
  • Solid Dosage Forms:

    • Powders, granules, tablets, capsules

Liquid Dosage Forms

  • Solution:

    • A homogenous mixture of solid, liquid, or gas in another liquid (e.g., water).
    • Utilizes specific therapeutic effects of soluble substances.
  • Examples of Solutions:

    • Antibacterial topical solutions (e.g., benzalkonium chloride) used for skin treatment.
    • Aromatic waters: Clear solutions of volatile oils used as flavoring or in emulsion/suspension bases.
    • Mixtures: Often aqueous, can be solutions or suspensions.
