Foam is defined as a mass of gas cells separated by thin films of liquid and formed by the juxtaposition of bubbles, giving a dispersion in which a large proportion of gas by volume is dispersed in a liquid. The pharmaceutical foams have a number of advantages compared with traditional drug delivery methods such as ointments, creams, lotions, gels, solutions, suppositories, creams and ointments. The European Pharmacopoeia contains a monograph called »Medicated Foams« (Musci medicata),which is also evidence that interest in this method of drug delivery is growing.

Most of them contain corticosteroids, antiseptics, antifungal drugs, anti-inflammatory drugs and local anesthetics
