Abstract

  The objective of the present study was to develop self microemulsifying drug delivery system (SMEDDS) for improving the delivery of a BCS class IV antiemetic drug, aprepitant (APT). The in vitro self-emulsification properties, droplet size analysis, drug content, polydispersity index, zeta potential etc. of these formulations upon their addition to water under mild agitation conditions were studied. The solubility of APT was found to be high in Capryol90 (12.53 ± 0.35); Labrasol (13.30 ± 0.23); Transcutol HP (49.15 ± 0.28) mg/ml. The range of mean droplet size was 13.97 ± 0.72 nm to 124.90 ± 0.20 nm while the polydispersibility values were in the range of 0.169 to 0.604 with a zeta potential of -41.1 mV. More than 90% of the drug released within 30 minutes when compared with pure drug release of 13% in 30 minutes. The SMEDDS formulations followed first order kinetics. The APT formulations were proved to be robust, stable to pH, and thermodynamically stable and formed clear transparent micro emulsions in few seconds. Thus, the study confirmed that the Aprepitant SMEDDS formulation can be used as a possible alternative to traditional oral formulations to improve its bioavailability.
