Abstract

Objective To prepare sildenafil citrate loaded nanostructured lipid carriers (SC-NLCs), characterize their physical and chemical properties, and evaluate their in vitro release.

Methods SC-NLCs were prepared by thin film ultrasonic dispersion method, and their physical and chemical properties were investigated. The content of sildenafil citrate in SC-NLCs released in vitro was determinated by HPLC. The release properties of SC-NLCs and sildenafil citrate solution in vitro were investigated by dynamic membrane dialysis.

Results SC-NLCs were dispersed in water as milky white and visible colloidal solution and had good dispersion characteristics. The transmission electron microscope observation showed that SC-NLCs were relatively round and evenly distributed. The average particle size, encapsulation efficiency, potential and polydispersity coefficient of SC-NLCs were 66.96 nm, (69.26±0.73)%, (18.00±4.84) mV and 0.247, respectively. The results of in vitro release test showed that the cumulative release of sildenafil citrate in the sildenafil citrate solution group was reached (97.32±3.14)% after 4 hours in PBS (pH 5.5), while the cumulative release of sildenafil citrate in the SC-NLCs group was about (72.16±2.51)% after 4 hours, then reaching the release platform after 24 hours with the cumulative release of (84.29±2.00)%.

Conclusion The prepared SC-NLCs have uniform particle size and uniform dispersion. In terms of in vitro release behavior, SC-NLCs also have good sustained-release properties.
