Solid Self Nano-Emulsifying Drug Delivery System of Dasatinib: Optimization, , and assessment.

Dasatinib (DST) is an oral tyrosine kinase inhibitor with poor aqueous solubility. To outwit this issue, a solid self-nano emulsifying drug delivery system (S-SNEDDS) of DST was formulated. I-optimal mixture design was used for optimization of DST-loaded SNEDDS using Linalool, Cremophor RH40 and Transcutol P. S-SNEDDS underwent physicochemical characterization, release and permeation, cell-based assays and pharmacokinetic study. DST-S-SNEDDS showed globule size and PDI of 141.53 ± 5.371 nm and 0.282 ± 0.020, respectively. DST-S-SNEDDS revealed significantly lower IC (1.825 μg/mL) than free DST (7.298 μg/mL) in MDA-MB-231. pharmacokinetic study revealed 1.94-fold increment in AUC for the DST-S-SNEDDS group than free DST. S-SNEDDS could be promising approach for improving bioavailability and efficacy of DST.
