A drug delivery system, e.g., microemulsion preconcentrate, that spontaneously forms a microemulsion when brought in contact with an aqueous medium. The drug delivery system contains valsartan, a hydrophilic component, a lipophilic component and a surfactant. A particularly useful hydrophilic component in the system is a polymer that is solid at room temperature, e.g., solid PEG. |
