    Study Notes

    Liquid Dosage Forms

    • Liquid dosage forms are formulations containing one or more APIs and excipients in a liquid state.
    • Liquid dosage forms can be solutions, suspensions, or emulsions.
    • Liquid dosage forms are used for both internal and external use.

    Advantages and Disadvantages of Liquid Dosage Forms

    • Advantages: easy to administer, accurate dosing, fast acting, versatile.
    • Disadvantages: taste issues, limited stability, difficulty administering to certain populations, inconvenient for travel and transportation.

    Pharmaceutical Solutions

    • Solutions are homogenous, molecular mixtures of two or more components.
    • Pharmaceutical solutions consist of a solute (drug and excipients) dissolved in a liquid solvent system.
    • Solutions are administered by various routes, including oral, otic, and parenteral.
    • Solutions are classified based on the formulation or traditionally by the solvent system, such as syrups, elixirs, spirits, and tinctures.

    Traditional Terms for Different Pharmaceutical Solutions

    • Aromatic Waters: saturated aqueous solutions of volatile oils or aromatic substances.
    • Elixirs: solutions containing alcohol as a cosolvent.
    • Spirits: alcoholic or hydro-alcoholic solutions of volatile substances, used as flavoring agents or for medicinal purposes.
    • Tinctures: alcoholic or hydro-alcoholic solutions prepared from vegetable materials or chemical substances.
    • Syrups: oral aqueous solutions with high concentrations of sucrose or other sugars.

    Advantages of Pharmaceutical Solutions

    • Solutions provide rapid drug action.
    • Solutions allow for accurate dosing through specific volume measurements.
    • Oral solutions are easily swallowed, beneficial for children and older individuals.
    • Solutions are easier to manufacture than other dosage forms.

    Disadvantages of Solutions

    • Many drugs are unstable in solution.
    • Many drugs are poorly soluble in water.
    • Solutions are bulky and less convenient for patients to carry than solid dosage forms.
    • Solutions are more expensive to transport.
    • Packaging requires higher quality materials.

    Excipients Used in Pharmaceutical Solutions

    • Excipients enhance product stability, bioavailability, appearance, aid in product manufacture, and identification.
    • Excipients should be stable, cost-effective, inert, nonirritant, and compatible with the formulation and route of administration.

    Excipients Used in Pharmaceutical Solutions: Flavouring Agents

    • Flavouring agents mask the taste of drugs.
    • Sweeteners like sucrose, sorbitol, and mannitol are used to improve palatability.
    • Synthetic and natural flavourings like vanilla, cinnamon, and menthol are used in oral and nasal solutions.
    • Flavour choice should consider patient population and cultural preferences.

    Excipients Used in Pharmaceutical Solutions: Colouring Agents

    • Colouring agents enhance patient acceptability.
    • Colour should correlate with the flavour (e.g., green with mint, red with cherry).
    • Labels should have strong adhesive strength and be resistant to water and UV light.

    Labelling

    • The FDA requires a "Drug Facts" table on all pharmaceutical product labels.
    • The table includes:
      • Active ingredients and their amounts per dosage.
      • Uses of the medicine.
      • Directions for taking the medicine.
      • Other information, including storage instructions.
      • Inactive ingredients.
      • Warnings, including:
      • "Do Not Use" statements.
      • "Ask a Doctor" or "Ask a Doctor or Pharmacist" statements.
      • "When Using This Product" statements for side effects and drug interactions.
      • "Stop and Ask a Doctor If" and "Stop Using If" statements for serious side effects.
      • "Keep Out of Reach of Children" statement.
