    Study Notes

    Drug Dosage Forms

    • A drug dosage form is the physical presentation of medication, impacting absorption, distribution, metabolism, and elimination.
    • Composed of active drug substances and excipients that enhance formulation properties.

    Solid Dosage Forms

    • Tablets: Compressed solid forms, often coated. Types include regular, sugar-coated, film-coated, enteric-coated, and effervescent tablets. They vary based on release mechanisms (immediate, extended, delayed).
    • Capsules: Gelatin or other edible materials containing medication. Types: hard-gel (two-piece) and soft-gel (single piece with liquid).
    • Powders: Finely ground medicinal substances, taken orally or topically.
    • Granules: Small spherical particles containing medication, used for a variety of applications.

    Liquid Dosage Forms

    • Solutions: Complete drug dissolution in a solvent, easily absorbed and administered.
    • Syrups: Concentrated sugar solutions with medicinal substances, palatable for children.
    • Emulsions: Mixtures of two immiscible liquids, stabilized for injection or infusion.
    • Suspensions: Liquid preparations with suspended drug particles, requiring shaking before use.

    Semisolid Dosage Forms

    • Creams: Emulsions containing oil and water, lighter for skin applications.
    • Ointments: Occlusive semisolid preparations for topical application.
    • Gels: Drug dispersed in a gel-forming agent, often for relieving skin irritation.
    • Pastes: Thick, stiff forms with a high powder content, preventing skin contact with irritants.

    Other Dosage Forms

    • Nasal Sprays: Treat nasal congestion using antihistamines or decongestants.
    • Oral Sprays: Deliver medication to the mouth and throat.
    • Aerosol Sprays: Fine mist application for both topical and inhalation.
    • Lozenges: Slow-dissolving oral forms for sustained therapeutic effects.

    Routes of Drug Administration

    • The route chosen affects drug absorption, distribution, metabolism, and elimination.

    Oral Route

    • Involves swallowing tablets, capsules, or liquids.
    • Advantages: Easy administration, convenient.
    • Disadvantages: Potential gastrointestinal effects, variable absorption.
    • Common examples: Pain relievers, antibiotics, vitamins.

    Sublingual and Buccal Routes

    • Sublingual: Medication placed under the tongue for rapid absorption.
    • Buccal: Placed between gums and cheek for sustained release, slower than sublingual.

    Topical Route

    • Direct application to skin or mucous membranes.
    • Advantages: Targeted application minimizes systemic side effects.
    • Disadvantages: Possibility of skin irritation.
    • Common forms: Lotions, creams, ointments, sprays.

    Transdermal Route

    • Medication applied via a patch for sustained release.
    • Advantages: Avoids frequent dosing.
    • Disadvantages: Risk of skin irritation or allergic reactions.
    • Examples include nicotine and pain relief patches.

    Parenteral Route

    • Injection methods bypassing the digestive system.
    • Intravenous (IV): Rapid absorption via veins.
    • Intramuscular (IM): Slower absorption in muscles.
    • Subcutaneous (SC): Slow and steady absorption in fatty tissue.

    Inhalation Route

    • Medication inhaled in aerosolized form for rapid lung delivery.
    • Advantages: Direct and quick absorption.
    • Disadvantages: May cause respiratory irritation.
    • Common examples: Asthma inhalers and bronchodilators.

    Nasal Route

    • Administration via nasal cavity as sprays or drops.
    • Advantages: Fast absorption; direct delivery to nasal passages.
    • Disadvantages: Potential for nasal irritation.
    • Examples: Nasal decongestants and corticosteroids.

    Rectal Route

    • Medication administered as a suppository.
    • Advantages: Avoids first-pass metabolism.
    • Disadvantages: Possible discomfort or embarrassment for patients.
