Soluplus® is a polymeric solubilizer with an amphiphilic chemical structure, which was particularly developed for solid solutions. Due to its bifunctional character, it is able to act as a matrix polymer for solid solutions on the one hand, and, on the other hand, it is capable of solubilizing poorly soluble drugs in aqueous media. Furthermore, Soluplus® can increase the bioavailability of poorly soluble drugs.
