“…The decrease in particle size may also increase the rate of absorption in some cases [13]. Amorphization of the drug: Conversion of the crystalline drug into its amorphous form increases the solubility, changing the crystal lattice's range order [14,15]. Increase in wettability of the drug: This increases the area of contact between the solvent and the drug thereby increasing the solubility [16].…”

Objective: The study aims to enhance the solubility and dissolution of ticagrelor by formulating an amorphous solid dispersion using the hot melt extrusion technique. Methods: Solubility of ticagrelor is very limited in water and buffers of pH 1.2 to 6.8, which is one of the prime reasons for its low oral bioavailability. Amorphous solid dispersions were prepared using the Hot Melt Extrusion technique using different polymers, plasticizers, and surfactants. The formulation is optimized based on the level of polymer in the formulation. The final formulation of Ticagrelor Amorphous Solid Dispersion is made with a drug-polymer ratio of 1:3, keeping the plasticizer level at 10% of the polymer along with a surfactant Sodium Lauryl Sulfate. Results: The formulation showed an increase in solubility of 193.95-times in water, 50.71-times in 0.1 N HCl, 332.74-times in pH 4.5 acetate buffer, and 85.20-times in pH 6.8 phosphate buffer as compared to the pure drug. The drug release of the final formulation was found to be 70.0±4.4%, 55.4±1.1%, 35.5±2.1%, and 30.0±0.8% at 90 min, while the reference product showed a release of 9.4±1.1%, 20.7±0.5%, 8.4±0.3%, and 7.8±0.2% at 90 min in water, 0.1 N HCl, pH 4.5 acetate buffer and pH 6.8 Phosphate Buffer respectively. The drug release of the final formulation was found to be 99.1±3.8% at 60 min in 0.2% w/v Polysorbate-80 in water. Conclusion: In the present study, the amorphous solid dispersion of the poorly-soluble drug ticagrelor was successfully prepared. The polymer, Plasdone S630, is considered the most suitable with ticagrelor for formulating amorphous solid dispersion using Hot Melt Extrusion technology to increase the solubility and dissolution of the drug.
