Jun 01, 2015 Poor aqueous solubility of some drug molecules is a major problem in drug formulation. Drug nanosuspensions emerged as one solution to delivering such hydrophobic drugs. Scaling down to nanoparticles enhances drug aqueous solubility and bioavailability by increasing drug surface area that comes into contact with biological media. Nanosuspensions that have attracted particular attention are ...
