Pharmaceutical Suspensions and Emulsions

The size range of the dispersed phase in pharmaceutical suspensions and emulsions is typically between 0.1-100 μm.
Suspending agents in pharmaceutical suspensions serve to prevent sedimentation and maintain the uniform distribution of the dispersed phase.
A disadvantage of pharmaceutical suspensions is that the particles may settle over time, leading to inconsistent dosing.

Composition of Pharmaceutical Suspensions

The external phase in pharmaceutical suspensions is generally composed of water or a aqueous solution.

Disadvantages of Liquid Dosage Forms

A disadvantage of liquid dosage forms is that they can be susceptible to microbiological contamination.

Examples of Pharmaceutical Suspensions

An example of a parenteral suspension is insulin.

Oily Vehicles for Liquid Dosage Forms

Mineral oil is an example of an oily vehicle for liquid dosage forms.

Coloring Agents for Liquid Dosage Forms

Certified food dyes are an example of a coloring agent for liquid dosage forms.

Wetting Agents in Liquid Dosage Forms

The purpose of a wetting agent in liquid dosage forms is to reduce the interfacial tension between the active pharmaceutical ingredient and the vehicle, allowing for better dispersion and dissolution.

Advantages of Liquid Dosage Forms

One advantage of liquid dosage forms is that they are often easier to administer to pediatric and geriatric patients, who may have difficulty swallowing solid dosage forms.
