    Study Notes

    Liquid Dosage Forms

    • Liquid dosage forms can be classified into monophase (single phase) and polyphasic (multiple phases) systems.
    • An example of a polyphasic liquid dosage form is an emulsion, which consists of two immiscible liquids.
    • Liquid dosage forms for ear administration include ear drops.

    Types of Liquid Dosage Forms

    • Topical liquid dosage forms are specifically formulated for application on body surfaces.
    • A solution is a type of liquid dosage form created by dissolving one or more solutes in a solvent.

    Emulsion Characteristics

    • In an oil-in-water (o/w) emulsion, the continuous phase is the aqueous phase (water).
    • In a water-in-oil (w/o) emulsion, the external phase is the oil phase.
    • O/w emulsions typically have small droplets of oil dispersed within a continuous water phase.

    Advantages of Emulsions

    • Emulsions are beneficial for oral administration of poorly soluble compounds, improving their bioavailability.
    • They allow for improved taste masking and enhanced stability of medicinal agents.
    • Emulsions can provide a controlled release of pharmaceuticals, enhancing therapeutic effects.

    Definition of Emulsion

    • An emulsion is defined as a mixture of two immiscible liquids where one liquid is dispersed in the other in the form of droplets.
