Abstract
Chrysin is a natural flavonoid with a wide range of bioactivities. Only a few investigations have assessed the analgesic activity of chrysin. The lipophilicity of chrysin reduces its aqueous solubility and bioavailability. Hence, self-nanoemulsifying drug delivery systems (SNEDDS) were designed to overcome this problem. Kollisolv GTA, Tween 80, and Transcutol HP were selected as oil, surfactant, and cosurfactant, respectively. SNEDDS A, B, and C were prepared, loaded with chrysin (0.1%w/w), and extensively evaluated. The optimized formula (B) encompasses 25% Kollisolv GTA, 18.75% Tween 80, and 56.25% Transcutol HP was further assessed. TEM, in vitro release, and biocompatibility towards the normal oral epithelial cell line (OEC) were estimated. Brain targeting and acetic acid-induced writhing in a mouse model were studied. After testing several adsorbents, powdered SNEDDS B was formulated and evaluated. The surfactant/cosurfactant (S/CoS) ratio of 1:3 w/w was appropriate for the preparation of SNEDDS. Formula B exhibited instant self-emulsification, spherical nanoscaled droplets of 155.4 ± 32.02 nm, and a zeta potential of - 12.5 ± 3.40 mV. The in vitro release proved the superiority of formula B over chrysin suspension (56.16 ± 10.23 and 9.26 ± 1.67%, respectively). The biocompatibility of formula B towards OEC was duplicated (5.69 ± 0.03 µg/mL). The nociceptive pain was mitigated by formula B more efficiently than chrysin suspension as the writhing numbers reduced from 8.33 ± 0.96 to 0 after 60 min of oral administration. Aerosil R972 was selected as an adsorbent, and its chemical compatibility was confirmed. In conclusion, our findings prove the therapeutic efficacy of chrysin self-nanoemulsion as a potential targeting platform to combat pain.

Abstract
Background Gastric ulcer is a prevalent disease with various etiologies, including non-steroidal anti-inflammatory drugs and alcohol consumption. This study aimed to explore the dual gastric protection effect of tadalafil and limonene as a self-nanoemulsifying system (SNES)-based orodispersible tablets. Methods Tadalafil-loaded limonene-based SNES was prepared, and the optimum formula was characterized in terms of particle size (PS), polydispersity index (PDI), and zeta potential (ZP) then loaded on various porous carriers to formulate lyophilized orodispersible tablets (ODTs). The ODTs were evaluated via determining hardness, friability, content uniformity, wetting, and disintegration time. The selected ODT was examined for its gastric ulcer protective effect against alcohol-induced ulcers in rat model. Ulcer score and ulcer index were computed for rats stomachs that were inspected macroscopically and histopathologically. Results The prepared SNES had droplet size of 104 nm, polydispersity index of 0.2, and zeta potential of −15.4 mV. From the different ODTs formulated, the formula with superior wetting time: 23.67 s, outstanding disintegration time: 28 s, accepted hardness value: 3.11 kg/cm2 and friability: 0.6% was designated. A significant gastroprotective effect of the unloaded and tadalafil-loaded ODTs was recognized compared to the omeprazole pre-treated group. Moreover, the histopathological analysis displayed very mild inflammation in the limonene-based ODTs group and intact structure in the tadalafil-loaded pre-treated animals. Conclusion Limonene gastroprotective effect functioned along with tadalafil in the form of SNES-incorporated ODTs could serve as a promising revenue for better efficacy in gastric ulcer prevention.

Abstract
Activity changes after olive oil (OO), pomegranate seed oil (PSO), and grape seed oil (GSO) were formulated into self-nanoemulsifying systems (SNES), were examined in this study. Only GSO SNES dramatically enhanced antioxidant activity of GSO. SNES from OO and PSO did not exert obvious impact on radical quenching ability of the oils. Though PSO exhibited significantly stronger strength over OO in suppressing E. coli (p < 0.05), the inhibitory effect of OO SNES against E. coli became slightly higher than that of PSO SNES. Similar phenomenon happened in GSO, OO, and their SNES for preventing Yeast growth. The study indicated that SNES sometimes reversed the strength order of the original oils in inhibiting bacteria.

Abstract
Preterm birth (PTB) is a major cause of infant mortality in the United States and around the globe. Makena®—once-a-week intramuscular injection of 17-α Hydroxyprogesterone caproate (17P)—is the only FDA approved treatment for the prevention of PTB. Invasive delivery of 17P requires hospitalization and expert personnel for injection. Vaginal delivery of 17P would be preferable, because of high patient compliance, reduced systemic exposure, fewer side effects, and no need for hospitalization. The objective of the present study was to prepare and evaluate a self-nanoemulsifying vaginal tablet of 17P. A solid self-nanoemulsifying preconcentrate (S-SNEDDS) of 17P and dimethylacetamide (DMA) was developed using medium chain triglycerides, a non- immunogenic surfactant, and co-processed excipient (PVA-F100). The tablet prepared was characterized for emulsification time, particle size, solid state properties, and drug release. The formulation showed >50% inhibition of TNF-α release from LPS-stimulated RAW 264.7 cells. Importantly, there were significant differences in rates of PTB and average time to delivery between control and vaginal 17P-treated groups in LPS-stimulated timed pregnant E15.5 mice. Considering the lacuna of therapeutic approaches in this area, vaginal delivery of 17P for the prevention of preterm birth has significant clinical relevance.

Abstract
The objective of the study was to develop baicalin loaded liquid self-nanoemulsifying drug delivery systems (BSNEDDS) and to characterize them by physicochemical methods in order to optimize the composition and quality attributes. Atomic force microscopy (AFM) was utilized to evaluate the morphological characteristics and size distribution of reconstituted nanoemulsion droplets with a new sample preparation method for the elucidation of individual nanodroplets without any signs of coalescence. Response surface methodology and desirability approach was used to select the optimized composition related to droplet size, zeta-potential, polydispersity index (PDI), and turbidity characteristics. Droplet size distribution measured by dynamic light scattering method was highly desirable with 52.87 ± 0.5322 nm, which was confirmed by AFM imaging. The optimized formula contains Peceol® (14.29%, w/w), Kolliphor® EL (57.14%, w/w), and Transcutol® P (28.57%, w/w). Long-term stability analysis did not show any significant change in droplet size or PDI over the investigated period. More than 40.5-times solubility improvement was achieved with the optimized BSNEDDS correlated to solubility of baicalin in distilled water. In vitro dissolution studies at pH 1.2 and pH 6.8 were performed and revealed that the optimized BSNEDDS formula showed pH independent drug dissolution, and 100% of incorporated baicalin dissolved within five minutes in rapidly dispersing nanodroplets.

Abstract
The oral administration of celecoxib (CLX) is a real problem because of its low aqueous solubility that results in high variability in absorption and its severe adverse effect such as cardiotoxic effects and gastrointestinal toxicity. Self-nanoemulsifying drug delivery systems (SNEDDS) can enhance the poor dissolution and erratic absorption of poorly water-soluble drugs such as CLX. This study was conducted to investigate the potential of SNEDDS to enhance the efficacy of CLX on inflamed mucous tissue and reduce systemic adverse effects by increasing its poor dissolution properties. A pseudo-ternary phase diagram was derived from the results of CLX solubility experiments in various excipients. These studies revealed the use of Labrafil M 2515 CS as oil, tween 80 as a surfactant, and polyethylene glycol 400 as a co-surfactant for the optimization of SNEDDS formulations. Eight formulations were formulated and characterized by their particle size, polydispersity index, viscosity, globular shape, drug solubility, self-emulsification efficiency, in vitro drug release, and permeation. The anti-inflammatory effect of CLX-SNEDDS was evaluated by carrageenan-induced cheek oedema in rats. The cheeks were treated with CLX-SNEDDS before oedema induction and then noticed for narrow periods (2 h) followed by histopathological studies to determine the efficacy of treatment. The selected formulations (F3 and F5) showed spherical morphologies under transmission electron microscopy, mean droplet sizes of 116.9 ± 1.78 and 124 ± 1.87 nm, respectively, complete in vitro drug release, and high cumulative amounts of drug permeation in 8 h. They also showed significant remarkable cheek oedema inhibition in comparison with the control groups (p < 0.05). CLX-SNEDDS was found to achieve effective local therapeutic concentration and intended to reduce cheek oedema, congestive capillary, inflammatory cells, and side effects due to lower dose size.

Abstract
The present study was undertaken to improve rosuvastatin (RSV) bioavailability and pharmacological response through formation of SNES using Perilla frutescens oil as lipid carrier. The composition of oil was estimated by fatty acid methyl ester (FAME) analysis using gas chromatography. Solubility of RSV in Perilla frutescens oil and Cremophor EL was 25.0 ± 3.0 and 60.0 ± 5.0 mg/mL, respectively. Later, nanophasic maps and a central composite design were employed to determine the maximum nanoemulsion region and further optimize SNES in this study. Finally, the optimized formulation was evaluated in vitro and in vivo. FAME analysis revealed that PUFA content was 70.3% of total fatty acid. Optimized SNES formulation demonstrated particle size of 17.90 nm, dissolution 98.80%, cloud point 45°C, emulsification time 2 min, and viscosity 241.41 ± 5.52 cP. The hypolipidemic property of SNES was further explored using Triton X-100-induced hyperlipidemic rat model, and there were reductions of serum cholesterol, triglyceride, and LDL and VLDL levels in the SNES-treated group as compared to the toxic control. Pharmacokinetic study of SNES revealed significantly higher C max (60.13 ± 25.43 ng/mL) and AUC0-∞ (6195 ± 42.38 ng h/mL) vis-à-vis marketed tablet (284.80 ± 13.44 ng/mL, 3131.72 ± 51.93 ng h/mL, respectively). RSV was successfully incorporated into ω-3 fatty acid-based SNES with improved pharmacokinetic parameters (~ 2-fold improved bioavailability) and better hypolipidemic properties, owing to the synergistic effects of hepatic lipid regulation itself. The results clearly explicated that ω-3 fatty acid-based SNES effectively enhanced bioavailability and pharmacological responses of RSV, suggesting that these formulations may be useful as alternative for hyperlipidemia treatment in future drug design perspective.

Abstract
OBJECTIVE The aim of this study is to develop and characterize self-nanoemulsifying drug delivery system (SNEDDS) of piroxicam in liquid and solid forms to improve its dissolution, absorption and therapeutic efficacy. MATERIALS AND METHODS The generation of liquid SNEDDS (L-SNEDDS) was composed of soybean or coconut oil/Tween 80/Transcutol HP (12/80/8%w/w) and it was selected as the optimized formulation based on the solubility study and pseudo-ternary phase diagram. Optimized L-SNEDDS and liquid supersaturatable SNEDDS (L-sSNEDDS) preparations were then adsorbed onto adsorbents and formulated as directly compressed tablets. RESULTS AND DISCUSSION The improved drug dissolution rate in the solid supersaturatable preparation (S-sSNEDDS) may be due to the formation of a nanoemulsion and the presence of drug in an amorphous state with hydrogen bond interaction between the drug and SNEDDS components. In vivo pharmacokinetic studies on eight healthy human volunteers showed a significant improvement in the oral bioavailability of piroxicam from S-sSNEDDS (F12) compared with both the pure drug (PP) and its commercial product (Feldene®) (commercial dosage form (CD)). The relative bioavailability of S-sSNEDDS (F12) relative to PP or CD was about 151.01 and 98.96%, respectively. CONCLUSION The obtained results ratify that S-sSNEDDS is a promising drug delivery system to enhance the oral bioavailability of piroxicam.

Abstract
The purpose of the present study was to formulate a self-nanoemulsifying system (SNES) containing model lipophilic drug, felodipine (FLD), to improve its solubility. The SNES was formulated using varying amounts of Miglyol 840 (as an oil), Cremophor EL (as a surfactant), and Capmul MCM (as a co-surfactant). The SNES were characterized for turbidity, droplet size and in vitro FLD release. The SNES containing oil, surfactant, and co-surfactant in the weight ratio of 3.5:1.0:1.0, respectively, showed good emulsification, median droplet size of 421 nm, and rapid FLD release (>90% release in 15 min). Gelling was induced in the SNES by addition of Aerosil 200 (A 200). Rheological studies clearly demonstrated the formation of gelled microstructure with enhanced elasticity for SNES with A 200. Since FLD warrants extended delivery for management of hypertension, the gelled SNES was further encased within the hydrophobic Gelucire 43/01 (GEL) coat to extend the release of FLD. Caprol PGE-860 (CAP) was added to this coat as a release enhancer. No interaction was seen between GEL and CAP in differential scanning calorimetry. The effect of two formulation variables in the encased SNES, viz., the gelling agent (A200) and the release enhancer (CAP), on the in vitro FLD release was evaluated using 3(2) factorial design experiments. CAP by virtue of channel formation in GEL coat favored the FLD release, while the A200 retarded the FLD release by inducing gelling. At later time points, an interaction between these two variables was found to govern extended release of FLD. The developed gelled SNES encased within the GEL coat can be used as an extended release composition for lipophilic drugs.
