Study Notes
Characteristics of Coarse Dispersions
- Coarse dispersions, including suspensions and emulsions, are characterized by a particle size range of 1 to 1000 micrometers.
Advantages of Pharmaceutical Suspensions
- The main advantage of using a pharmaceutical suspension is that it allows for improved stability of the active ingredient, especially for poorly soluble drugs.
Dispersed Phase in Pharmaceutical Suspensions
- The dispersed phase in a pharmaceutical suspension consists of solid particles suspended in a liquid medium.
Ideal Properties of Pharmaceutical Suspensions
- An ideal pharmaceutical suspension should exhibit properties such as stability, uniformity, and the ability to remain suspended without sedimentation for a significant period.
Disadvantages of Pharmaceutical Suspensions
- A notable disadvantage associated with pharmaceutical suspensions is the potential for sedimentation, leading to uneven dosages and requiring shaking before use.
Definition of Liquid Dosage Forms
- Liquid dosage forms are defined as preparations in which the active pharmaceutical ingredients are formulated as liquids for administration.
Types of Liquid Dosage Forms
- Solutions are liquid dosage forms prepared by dissolving active ingredient(s) in either aqueous or non-aqueous solvents.
Two-Phase Liquid Dosage Forms
- The term used to describe a liquid dosage form composed of two phases, where one phase is uniformly dispersed in the other, is an emulsion.
Definition of Dispersed Phase
- In a disperse system, the term 'dispersed phase' refers to the phase that consists of the dispersed particles in the dispersion medium.
Liquid Preparations with Undissolved Drug
- Liquid preparations containing undissolved or immiscible drug distributed throughout a vehicle are classified as suspensions.
