Development of Solid Self – Nanoemulsified Drug Delivery System Containing Rosuvastatin

This study aims to solidify the self-nanoemulsifying drug delivery system with rosuvastatin (SNEDDS Ros) for application in solid dosage forms. The liquid SNEDDS Ros system is solidified by granulation and spray drying methods. Solid SNEDDS Ros was evaluated on the drug content, the Carr index, nanoemulsification efficiency and several criteria of nanoemulsion, formed after emulsification of solid SNEDDS Ros, such as droplet size, polydispersion index (PDI), the drug proportion in the oil phase. The study results show that solid SNEDDS Ros, prepared by granulation method using Prosolv SMCC 90 as an adsorbent, had good flowability with the Carr index of about 15. The nanoemulsion, obtained after emulsification of the solid SNEDDS, had an average particle size of 15 nm, PDI less than 0.2, drug nanoemulsified efficiency of 94 % and drug proportion in the oil phase of 84%.
