Emulsion in Pharmacy

Emulsion in pharmacy: features and application

An emulsion is a mixture of two insoluble liquids prepared with the help of an emulsifier. In pharmacy, emulsions are widely used to create drugs that cannot be dissolved in water or other solvents.

The advantages of using emulsions in pharmacy are that they can improve the absorption and bioavailability of medicinal substances, improve their stability and ease of use.

One of the features of emulsions is that they can be either water-oil or oil-water. In water-oil emulsions, the oil is inside the water, and in oil-water emulsions, it is the other way around. There are also other types of emulsions that can be used in pharmacy.

To prepare emulsions in pharmacy, special emulsifiers are used that help mix two insoluble liquids. These emulsifiers can be of plant, animal or synthetic origin.

Emulsions in pharmacy are widely used to create medications such as creams, ointments, lotions and others. They are also used to prepare injection solutions and other medical products.

One example of an emulsion in pharmacy is the drug Multigel, which is used to treat joint diseases. This medication contains an emulsion consisting of eucalyptus oil, tea tree oil and other components.

Also, emulsions in pharmacy can be used to create cosmetics. For example, they can be added to face creams to improve their texture and moisturizing properties.

In conclusion, emulsions in pharmacy represent an important tool for the creation of drugs and cosmetics. They make it possible to improve the absorption and bioavailability of medicinal substances, as well as the convenience of their use.

Emulsion in pharmacy

An emulsion is a medical product that is a homogeneous dispersion of one liquid phase (from one or more liquids) in another liquid phase (also from one or more different liquid phases).

One liquid phase (base) is contained between particles of another liquid phase (outer emulsion). Phase separation is usually based on surface tension and adhesion. The outer emulsion phase stabilizes the inner core of the emulsion by spontaneously releasing liquid into the outer layer (on the outside of the emulsion core), due to the formation of groupings of molecules: either due to strong intermolecular interactions, or through electrostatic or specific interactions (when biological proteins act as one liquid) . Examples of emulsion forms: aerosol, suspension (with liquid dispersed medium). In 1889, French physicist Jean Aubin discovered that oils and waters could be mixed with each other using a siphon with a rubber tube. This method is called emulsion, where the ester base forms droplets within droplets of the water base. Emulsions are stabilized by surfactants. Without emulsifiers, the emulsified state quickly breaks down. Therefore, each type of emulsion has its own e
