What are emulsions in pharmaceutical terms?

Emulsions, in pharmaceutical terms, refer to a mixture of oil and water that are combined in such a way that one is dispersed in the other, typically with the help of emulsifiers. This process creates a stable formulation that can be utilized in various pharmaceutical and cosmetic products, allowing for the combination of ingredients that would not ordinarily mix.

In pharmacology, emulsions can be important because they help to improve the bioavailability of certain drugs by enhancing their absorption through lipid membranes. This mechanism can be especially crucial for drugs that are hydrophobic or lipophilic, and emulsions can also aid in the uniform distribution of active ingredients in a formulation.

Understanding emulsions is critical for pharmacy technicians, as they may prepare or dispense such formulations, ensuring the stability and efficacy of the medications being provided.
