DEVELOPMENT AND OPTIMIZATION OF SUPER SATURABLE SELF-NANO EMULSIFYING DRUG DELIVERY SYSTEM FOR DASATINIB BY DESIGN OF EXPERIMENT

Abstract

Objective: In current research, Self-Nanoemulsifying Super Saturable Drug Delivery Systems S‑SNEDDS was formulated to attain superior drug dissolution and stability. Methods: Using saturated solubility, capryol ® 90, cremophor®-EL, and transcutol HP were used to make S-SNEDDS. Its composition was optimized using the ternary phase diagram. Using the central composite design of Response Surface Methodology, dasatinib-SNEDDS developed responses for droplet size (Y1), polydispersity index (Y2), and % drug released in 15 min (Y3). Various Precipitation Inhibitors were added to optimize SNEDDS (S3) to make S-SNEDDS and evaluate. Results: The optimum formulation was S3, with a particle size of 128 nm and zeta potential of-21 mV. Methylcellulose was shown better supersaturation than other inhibitors. The optimized formulation (F3) was more stable than ordinary SNEDDS due to its more significant zeta potential (-25 mV) and lower particle size (128 nm). Dasatinib was shown to be amorphous in S-SNEDDS using Differential Scanning Calorimetry and X-ray Powder Diffraction. F3 had a higher 90 min release rate (>99%) than pure drug dispersion (26%) and SNEDDS formulation (95%). Conclusion: The results concluded that S-SNEDDS formulation successfully enhanced the dissolution and stability of dasatinib.
