Abstract

Foams are becoming more and popular in several areas of our lives, including pharmaceutics and cosmetics. They are colloid systems where gas is dispersed in liquid phase Active ingredient bearing pharmaceutical foams are traditionally applied topically (dermal, local rectal, vaginal), but formulations for other delivery routes (e.g. nanosystems parenterally, solid foams orally) are also available. Numerous advantages are attached to foams when compared to traditional vehicles, resulting in increased patient compliance. Amongst others, the suitable composition contributes to quick, oily residue‑free and convenient application even on large or hairy areas, as well as to good drug transfer rate.
