Solidified self nano-emulsifying drug delivery system of rosuvastatin calcium to treat diet-induced hyperlipidemia in rat: in vitro and in vivo evaluations.
The present work focuses on preparing a solidified self nano-emulsifying drug-delivery system (S-SNEDDS) to improve the in vitro dissolution of rosuvastatin and to evaluate its antihyperlipidemic activity. Powder flow characterization demonstrated good flow properties. The drug-excipient compatibility study indicates no possible interaction. Transmission electron microscopy and scanning electron microscopy revealed nonaggregated, spherical nanosized globules. The globule-size analysis revealed droplet size in nanorange (∼100 nm). S-SNEDDS exhibited improved drug release (∼95%) as compared with rosuvastatin powder (51.89%) at 60 min. Upon antihyperlipidemic study, S-SNEDDS after 14th day of treatment revealed significant reduction in cholesterol (33.47%), triglycerides (40.77%) and atherogenic index (81.28%), while high-density lipoprotein (118.43%) was increased. The study indicates the great potential of S-SNEDDS for improving oral absorption of such poorly soluble drugs and their pharmacodynamic efficacy.
