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.
