Enhancement of the solubility, dissolution and bioavailability of the drugs is the challenging task for the research sector. As many of the solubility enhancement techniques are available to achieve the desired goal, but the older techniques don’t show the expected results for solubility enhancement and bioavailability as well, and they are unstable also some time.  But today the scenario is different because the novel techniques of solubility enhancement are available, such as hydrotropy, supercritical fluid process, sonocrystallisation, inclusion complex system, spray drying, microwave assisted techniques, etc. this novel techniques have the ability to give the reproducible results for solubility enhancement in pharmaceutical product development.  present review article deals with the different techniques for the solubility enhancement of the poorly soluble drug candidates.
