Development of the In-house Specifications and Study of the Stability of Self-nanoemulsifying Drug Delivery System Containing Rosuvastatin

Abstract

This study develops the in-house specifications of self-nanoemulsifying drug delivery system (SNEDDS) containing rosuvastatin based on the following criteria: description, identification, droplet size (≤200 nm) and polydiversity index (not more than 0.3), drug proportion in the oil phase (≥ 90.0%), assay (≥ 95.0% and ≤105.0% of the labeled amount of rosuvastatin (C₂₂H₂₈FN₃O₆S). The criteria were validated and the results were suitable for identification and determination of rosuvastatin in SNEDDS. Additionally, the results of the stability study show that the rosuvastatin SNEDDS met the criteria of description, droplet size, PDI, assay and drug rate in the oil phase for 12-month storage under the long-term condition (12 months) and 6 months on accelerated condition.

Keywords
