Abstract The dissolution rate of drugs is a determining factor for drug bioavailability after oral administration. This factor provides the main challenge in development and formulation of effective drug candidates. Now more than 40% of drugs in the development pipelines and about 60% of the drugs coming from synthesis suffer from low bioavailability after oral administration with poor drug dissolution being the main reason for this. Accordingly, scientists are probing many approaches to enhance drug dissolution rate. These include particle size reduction, microemulsification, micellar solubilization, co-solvency, complexation with suitable polymer, modulation of the chemical structure and formulation of solid dispersions with hydrophilic polymers. |
