However, a poor oral bioavailability of NOR creates a barrier for its development and application.Methods: A new self-nanoemulsifying drug delivery system (SNEDDS) loaded with the phospholipid complex (PC) was designed to improve the oral bioavailability of NOR. NOR-PC was prepared by solvent evaporation method with a mixture of phospholipid and NOR at a mass ratio of 3:1. The property of PC is to improve the liposolubility of NOR, and made PC embedded in the drug delivery system. The physicochemical property of NOR-PC was characterized by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR). According to the ability to dissolve NOR-PC, the oil and cosurfactant were chosen. The surfactant was selected based on its emulsification efficiency in SNEDDS. Pseudo-ternary phase diagram was created to select the best formulation of NOR-PC-SNEDDS, and the pharmacokinetic parameters were detected in rats. In addition, intestinal lymphatic transport and liver microsome experiment were studied to gain insight into the mechanism for NOR-PC-SNEDDS increasing the oral bioavailability of NOR.Results: Solubility detection showed that the PC significantly improved the liposolubility of NOR. NOR-PC-SNEDDS was prepared using NOR-PC, Ethyl oleate, Labrasol, Cremophor EL and transcutol HP at a weight ratio of 1:2:3.36:2.24:2.4 (w/w/w/w/w). The particle size and zeta potential of NOR-PC-SNEDDS were 36.72±1.47 nm and −4.91±0.49 mV after dilution with distilled water at a ratio of 1:50 (w/w). The absolute bioavailability of NOR in the NOR-PC-SNEDDS group significantly increased and the value was 372% in relative to NOR group. Further studies indicated that NOR-PC-SNEDDS promoted the oral bioavailability of NOR by enhancing intestinal lymphatic absorption and inhibiting Phase II metabolism of NOR.Conclusion: These findings suggested that NOR-PC-SNEDDS was able to promote the oral bioavailability of NOR, which provided a foundation for the further development and application of NOR.Keywords: norisoboldine, oral bioavailability, self-nanoemulsifying drug delivery system, lymphatic absorption, Phase II metabolismZhang JWen XDai YXia YDove Medical Pressarticlenorisoboldineoral bioavailabilityself-nanoemulsifying drug delivery systemlymphatic absorptionII-phase metabolismMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 14, Pp 7095-7106 (2019)
