title: Nanosuspensions as a new approach for the formulation for the poorly soluble drug tarazepide.
abstract: Poorly soluble drugs are often a challenging problem in drug formulation, especially when the drug is not soluble in either aqueous media or organic solvents. Attempts to overcome the solubility problem are, e.g. solubilisation with mixed micelles or forming a complex using cyclodextrines, but these approaches are of limited success. Another problem with new high potential drug is that these drugs often show bioavailability problems. One tried to improve the in vivo performance of poorly soluble drugs by reducing the particles size of the drug thus leading to an increased surface area and an increased dissolution velocity (Müller et al., 1994, 1999). Some of these problems occurred with tarazepide and therefore it was tried to create a formulation with this drug as nanosuspension which is suitable for intravenous administration.
