Basics of Compounding: Compounding Foams.

Pharmaceutical foams are gaining in popularity. The use of foam technology now delivers a range of topical active agents, including corticosteroids, other anti-inflammatories, sunscreen compounds, and antibacterial, antifungal, and antiviral agents. In addition to the distinct application advantages and improved patient compliance with foams, a real reason for the rapid growth of topical foam technology is that foams are elegant and aesthetically and cosmetically appealing products that provide an alternative to ointments, creams, lotions, and gels in the highly competitive dermatological market. In addition to all this, foams can be easily compounded for patients to take advantage of the uniqueness and applicability of this dosage form in medication administration. As an example, for the treatment of inflamed skin conditions such as sunburn and eczema, topical foams are preferred because they can be spread more easily and thereby minimize the amount of rubbing required to distribute the formulations. Another innovative use of forms is in administering a liquid medication to a bedridden patient. When a liquid is placed in a spoon or measuring device, it may spill. However, if the foam is placed in the spoon, it can be delivered to the patient without spilling. Properly formulated, this foam can be spill resistant, reproducible, easily flavored and taste masked, and pediatric and geriatric friendly.
