Formulation and Evaluation of Self-Micro Emulsifying Drug Delivery System (SMEDDS) of Ticagrelor

Abstract

The present work mainly emphasized on the enhancement of solubility of Ticagrelor by developing Self- Micro emulsifying drug delivery system. Ticagrelor is a BCS class IV drug with poor aqueous solubility and permeability. The saturated solubility of Ticagrelor in various oils, surfactants and co-surfactants was determined by using UV-spectroscopy. The excipients were selected based on their maximum solubility and compatibility for Ticagrelor. SMEDDS formulations od Ticagrelor were developed using different oils, surfactants and co-surfactant combinations (4:1 and 3:1). Pseudo ternary phase diagrams were constructed and based on pseudo ternary phase diagrams, Nano emulsification area was evaluated .Formulations were designed based on the pseudo ternary phase diagram using various proportions of oil (Capmul MCM E8 EP), surfactant (Labrasol), co-surfactant (PEG-400). The prepared formulations were selected among them F1 was optimized and carried out for further evaluations like dispersibility test, self-emulsification time ,phase separation and stability test, thermodynamic stability studies, droplet size and zeta potential, invitro drug release studies. The results of present study demonstrate that Ticagrelor SMEDDS can be used as a potential means for improving the solubility of Ticagrelor.
