AbstractBoth quercetin and resveratrol are promising plant-derived compounds with various well-described biological activities; however, they are categorized as having low aqueous solubility and labile natural compounds. The purpose of the present study was to propose a drug delivery system to enhance the oral bioavailability of combined quercetin and resveratrol. The suitable self-microemulsifying formulation containing quercetin together with resveratrol comprised 100 mg Capryol 90, 700 mg Cremophor EL, 200 mg Labrasol, 20 mg quercetin, and 20 mg resveratrol, which gave a particle size of 16.91 ± 0.08 nm and was stable under both intermediate and accelerated storage conditions for 12 months. The percentages of release for quercetin and resveratrol in the self-microemulsifying formulation were 75.88 ± 1.44 and 86.32 ± 2.32%, respectively, at 30 min. In rats, an in vivo pharmacokinetics study revealed that the area under the curve of the self-microemulsifying formulation containing quercetin and resveratrol increased approximately ninefold for quercetin and threefold for resveratrol compared with the unformulated compounds. Moreover, the self-microemulsifying formulation containing quercetin and resveratrol slightly enhanced the in vitro antioxidant and cytotoxic effects on AGS, Caco-2, and HT-29 cells. These findings demonstrate that the self-microemulsifying formulation containing quercetin and resveratrol could successfully enhance the oral bioavailability of the combination of quercetin and resveratrol without interfering with their biological activities. These results provide valuable information for more in-depth research into the utilization of combined quercetin and resveratrol.

The main objective of this work was to prepare a self-micro emulsifying drug delivery system (SMEDDS) for enhancement of oral bioavailability of domperidone, a poorly water soluble drug. The solubility of the drug was determined in various vehicles. A pseudo ternary phase diagram was constructed to identify the self-micro emulsification region. The in vitro self-micro emulsification properties and droplet size analysis of SMEDDS were studied following their addition to water under mild agitation. Further, the resultant formulations were investigated for clarity, phase separation, globule size, effect of pH and dilutions (1:100, 1:500, 1:1000) and freeze-thaw stability. The optimized formulation, SMEDDS-B used for in vitro dissolution and bioavailability assessment, contained oil (Labrafac CC, 25 %, m/m), surfactant (Tween 80, 55 %, m/m), and co-surfactant (Transcutol®, 20 %, m/m). The preliminary oral bioavailability of domperidone from SMEDDS was 1.92-fold higher compared to that of domperidone suspension in rats. The AUC0-24 and cmax values were 3.38 ± 0.81 μg h mL-1 and 0.44 ± 0.03 μg mL-1 for SMEDDS-B formulation in comparison with 1.74 ± 0.18 μg h mL-1 and 0.24 ± 0.02 μg mL-1 for domperidone suspension, suggesting a significant increase (p < 0.05) in oral bioavailability of domperidone from SMEDDSS.

Abstract The self-nanoemulsifying drug delivery system has shown many advantages in drug delivery. In this study, a self-nanoemulsifying drug delivery system of buckwheat flavonoids was prepared for enhancing its antioxidant activity and oral bioavailability. A nanoemulsion of buckwheat flavonoids was developed and characterized, and its antioxidant, in vitro release, and in vivo bioavailability were determined. The nanoemulsion was optimized by the central composite design response surface experiment, and its particle size, polymer dispersity index (PDI), zeta potential, morphology, encapsulation efficiency, and stability were evaluated. The antioxidant activity was tested by measuring its 2,2-diphenyl-1-picrylhydrazyl scavenging activity, hydroxyl radical scavenging activity, and superoxide anion scavenging ability. In vitro release of buckwheat flavonoids nanoemulsion showed a higher cumulative release than the suspension, and the release fitting model followed the Ritger–Peppas and Weibull models. The effective concentration of the nanoemulsion was evaluated in vivo using a Wistar rat model, and the area under the plasma concentration-time curve of the buckwheat flavonoids nanoemulsion was 2.2-fold higher than that of the buckwheat flavonoid suspension. The Cmax of the nanoemulsion was 2.6-fold greater than that of the suspension. These results indicate that the nanoemulsion is a promising oral drug delivery system that can improve the oral bioavailability to satisfy the clinical requirements.

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%.
