| Summary: | The emerging trend in the drug discovery process towards identification of poorly-soluble compounds as the lead drug candidates is a consequence of the inherent bias in the high-throughput drug screening method towards lipophilic molecules. Over 40% of the newly discovered drug molecules that are currently in the pharmaceutical pipeline exhibit a poor aqueous solubility that limits their therapeutic efficacy. In addition, approximately 17% of the drug products that are available in the market exhibit a low bioavailability as a result of the poor solubility of their solid dosage form formulation necessitating the use of high and frequent dosings. The systemic bioavailability of poorly-soluble compounds can be greatly enhanced by encapsulating the drug molecules into biocompatible nanoparticulate carriers as a result of the higher dissolution rate. |
