Hybrid polymeric microspheres for enhancing the encapsulation of phenylethyl resorcinol.

Phenylethyl resorcinol (PR) has been known to allow the whitening effect by inhibiting formation of tyrosinase. PR has solubility of 4.05 ± 0.

Strategic approach to developing a self-microemulsifying drug delivery system to enhance antiplatelet activity and bioavailability of ticagrelor.

Background: Ticagrelor (TCG) is used to inhibit platelet aggregation in patients with acute coronary syndrome, but its poor solubility and low bioavailability limit its in vivo efficacy. The purpose of this study was to manufacture an optimized TCG-loaded self-microemulsifying drug delivery system (SMEDDS) to enhance the oral bioavailability and antiplatelet activity of TCG.

Materials And Methods: Solubility and emulsification tests were conducted to determine the most suitable oils, surfactants, and cosurfactants.
