Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in western countries and China. Fenofibrate (FNB) can activate peroxisome proliferator-activated receptor α (PPARα) to increase fatty acid oxidation and ameliorate NAFLD. However, the application of FNB is limited in clinic due to its poor water solubility and low oral bioavailability. In this study, FNB-loaded nanoparticles (FNB-NP) based on a reactive oxygen species (ROS)-responsive peroxalate ester derived from vitamin E (OVE) and an amphiphilic conjugate 1,2-distearoyl-sn-glycerol-3-phosphoethanolamine-N-[methoxy(poly(ethylene glycol))-2000] (DSPE-PEG) were developed to enhance the preventive effects of FNB against NAFLD. In in vitro studies, FNB-NP displayed a high encapsulation efficiency of 97.25 ± 0.6% and a drug loading efficiency of 29.67 ± 0.1%, with a size of 197.0 ± 0.2 nm. FNB released from FNB-NP was dramatically accelerated in the medium with high H2O2 concentrations. Moreover, FNB-NP exhibited well storage stability and plasma stability. In pharmacokinetic (PK) studies, FNB-NP, compared with FNB crude drug, significantly increased the AUC0→t and AUC0→∞ of the plasma FNB acid by 3.3- and 3.4-fold, respectively. In pharmacodynamics (PD) studies, compared with an equal dose of FNB crude drug, FNB-NP more significantly reduced hepatic lipid deposition via facilitating FNB release in the liver and further upregulating PPARα expression in NAFLD mice. Meanwhile, oxidative stress in NAFLD was significantly suppressed after FNB-NP administration, suggesting that OVE plays a synergistic effect on antioxidation. Therefore, ROS-sensitive FNB delivery formulations FNB-NP enhance the preventive effects of FNB against NAFLD and could be further studied as a promising drug for the treatment of NAFLD in clinic.

Pharmaceuticals (Basel) 2022; 15:ph15070869. [PMID: 35890167 PMCID: PMC9321241 DOI: 10.3390/ph15070869] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 06/27/2022] [Accepted: 07/12/2022] [Indexed: 11/16/2022] Open
Abstract
Plant mucilages are commonly employed as excipients in pharmaceutical manufacturing. Ocimum basilicum (Lamiaceae family), a source of hydrophilic mucilage referred herein as Ocicum, was evaluated for the solubility enhancer of a model drug, aceclofenac, in solid dispersions prepared using different methods. Polymer was extracted from O. basilicum and solid dispersions of aceclofenac were fabricated with Ocicum or Poloxamer 407 using polymer-to-drug ratios of 1:1, 1:2 and 1:3 utilizing solvent evaporation, lyophilization and melt methods. Ocicum was evaluated for its safety via acute toxicity study including different biochemical and hematological parameters including liver and kidney profiles. Moreover, different characterization studies including melting-point, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and differential thermal analysis (TGA) were used for evaluation of polymer and solid dispersions. Furthermore, solubility and dissolution studies were performed to confirm solubility enhancement. Ocicum was found to be safer, and different characterization studies confirmed the purity of the compounds. In addition, Ocicum exhibited up to 6.27-fold enhanced solubility as compared to pure aceclofenac; similarly, 4.51-fold increased solubility by the synthetic polymer in their respective solid dispersions was shown. Furthermore, Ocicum-based solid dispersions showed substantial improvement in dissolution of aceclofenac. Therefore, it can be concluded from the above-mentioned results that Ocicum might be used as an economical natural oral delivery carrier alternative to the synthetic polymers.

Pharmaceutics 2021; 13:pharmaceutics13111771.

Abstract
Comminution of BCS II APIs below the 1 μm threshold followed by solidification of the obtained nanosuspensions improves their dissolution properties. The breakage process reveals new crystal faces, thus creating altered crystal habits of improved wettability, facilitated by the adsorption of stabilizing polymers. However, process-induced transformations remain unpredictable, mirroring the current limitations of our atomistic level of understanding. Moreover, conventional equations of estimating dissolution, such as Noyes–Whitney and Nernst–Brunner, are not suitable to quantify the solubility enhancement due to the nanoparticle formation; hence, neither the complex stabilizer contribution nor the adsorption influence on the interfacial tension occurring between the water and APIs is accounted for. For such ternary mixtures, no numeric method exists to correlate the mechanical properties with the interfacial energy, capable of informing the key process parameters and the thermodynamic stability assessment of nanosuspensions. In this work, an elastic tensor analysis was performed to quantify the API stability during process implementation. Moreover, a novel thermodynamic model, described by the stabilizer-coated nanoparticle Gibbs energy anisotropic minimization, was structured to predict the material’s system solubility quantified by the application of PC-SAFT modeling. Comprehensively merging elastic tensor and PC-SAFT analysis into the systems-based Pharma 4.0 algorithm provided a validated, multi-level, built-in method capable of predicting the critical material quality attributes and corresponding key process parameters.

Abstract
![]()
In this study, the
phase diagram of the ternary system of ezetimibe–simvastatin–fenofibrate
was established. It has been proven that the ternary composition recommended
for the treatment of mixed hyperlipidemia forms a eutectic system.
Since eutectic mixtures are characterized by greater solubility and
dissolution rate, the obtained result can explain the marvelous medical
effectiveness of combined therapy. Considering that another well-known
method for improving the aqueous solubility is amorphization, the
ternary system with eutectic concentration was converted into an amorphous
form. Thermal properties, molecular dynamics, and physical stability
of the obtained amorphous system were thoroughly investigated through
various experimental techniques compared to both: neat amorphous active
pharmaceutical ingredients (considered separately) and other representative
concentrations of ternary mixture. The obtained results open up a
new way of selecting the therapeutic concentrations for combined therapies,
a path that considers one additional variable: eutecticity.

Abstract
Lipid-based formulations, such as self-microemulsifying drug-delivery systems (SMEDDSs), are promising tools for the oral delivery of poorly water-soluble drugs. However, failure to maintain adequate aqueous solubility after coming into contact with gastrointestinal fluids is a major drawback. In this study, we examined the use of a novel cinnamic acid-derived oil-like material (CAOM) that binds drugs with a high affinity through π-π stacking and hydrophobic interactions, as an oil core in a SMEDDS for the oral delivery of fenofibrate in rats. The use of the CAOM in the SMEDDS resulted in an unprecedented enhancement in fenofibrate bioavailability, which exceeded the bioavailability values obtained using SMEDDSs based on corn oil, a conventional triglyceride oil, or Labrasol, an enhancer of intestinal permeation. Further characterization revealed that the CAOM SMEDDS does not alter the intestinal permeability and has no inhibitory activity on P-glycoprotein-mediated drug efflux. The results reported herein demonstrate the strong potential of CAOM formulations as new solubilizers for the efficient and safe oral delivery of drugs that have limited water solubility.

Abstract
The main antiviral drug-cyclodextrin interactions, changes in physicochemical and physiological properties of the most commonly used virucides are summarized. The potential complexation of antiviral molecules against the SARS-Cov2 also pointed out the lack of detailed information in designing effective and general medicines against viral infections. The principal problem of the current molecules is the 3D structures of the currently active compounds. Improving the solubility or bioavailability of antiviral molecules is possible, however, there is no universal solution, and the complexation experiments dominantly use the already approved cyclodextrin derivatives. This review discusses the basic properties of the different cyclodextrin derivatives, their potential in antiviral formulations, and the prevention and treatment of viral infections. The biologically active new cyclodextrin derivatives are also discussed.

Abstract
Cyclophosphamide (CP) is a chemotherapy alkylating agent that causes a lot of side effects including premature ovarian failure (POF). This study aimed to evaluate the possible protective effect of fenofibrate (FEN) in CP-induced POF. Rats were randomly divided into five groups as follows: negative control, CP, triptorelin (TRI)-treated, FEN (FEN)-treated, and FEN + TRI-treated. Histological study, collagen area fraction, and immunoexpression of proliferating cell nuclear antigen (PCNA) were evaluated. Also, estrogen, anti-mullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and ovarian malondialdehyde (MDA), nitric oxide (NOx), reduced glutathione (GSH), superoxide dismutase (SOD), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α), and vascular endothelial growth factor (VEGF) were measured. CP significantly reduced ovarian follicle count, as compared with the control group (1.00 ± 0.76 versus 7.75 ± 1.83, respectively). Meanwhile, FEN, either solely or in combination with TRI, significantly increased ovarian follicle count, as compared with the CP group (3.88 ± 0.83 and 5.75 ± 1.39, respectively). As compared with the control group, CP increased the levels of MDA, NOx, IL-10, TNF-α, FSH, LH, and collagen area fraction; however, levels of GSH, SOD, VEGF, AMH, estrogen, and PCNA immunoexpression were reduced with CP. Administration of FEN either solely or in combination with TRI showed significant improvement in all the parameters previously mentioned. FEN can protect the ovary from CP-induced side effects possibly through antioxidant and anti-inflammatory actions.

Abstract
BACKGROUND Piroxicam exhibits low oral bioavailability, due to its meager solubility in water. The intent of this study was to ameliorate the bioavailability of the drug by employing a solubility-enhancing encapsulation technique. METHODS Seven samples were formulated with piroxicam and gelatin using both solvent evaporation and electrospraying together. Evaluation of solubility and release rate in water and assessment of bioavailability in rats were carried out in comparison with piroxicam plain drug powder (PPDP). Other in vitro explorations were accomplished using powder X-ray diffraction analysis, differential scanning calorimetry, thermogravimetric analysis, scanning electron microscopy, and Fourier-transform infrared spectroscopy. RESULTS All piroxicam-loaded gelatinnanocontainers (PLGNs) enhanced solubility and release of the payload in water. In particular, a PLGN formulation consisting of piroxicam and gelatin at a 1:8 (w:w) ratio presented about 600-fold the drug solubility of that shown by PPDP. Moreover, 85.12%±10.96% of the payload was released from this formulation in 10 minutes which was significantly higher than that dissolved from PPDP in 10 minutes (11.81%±5.34%). Drug content, drug loading, and encapsulation efficiency of this formulation were 93.41%±0.56%, 10.45%±0.06%, and 66.74%±6.87%, respectively. The drug loaded in PLGNs existed in the amorphous state, as confirmed by X-ray diffraction and differential scanning-calorimetry analyses, and was more stable when analyzed by thermogravimetric analysis. Moreover, Fourier-transform infrared spectroscopy analysis suggested nonexistence of any piroxicam-gelatin interaction in the formulation. In the scanning electron-microscopy image, PLGNs appeared as round, smooth particles, with particle size of <1,000 nm. Amelioration in bioavailability of piroxicam with the aforementioned PLGN formulation was fourfold that of PPDP. CONCLUSION The PLGN formulation fabricated with piroxicam and gelatin at 1:8 (w:w) might be a promising system for enhanced biopharmaceutical performance of the drug.

Abstract
An established pharmaceutical strategy to increase oral drug absorption of low solubility–high permeability drugs is to create nanoparticles of them. Reducing the size of the solid-state particles increases their dissolution and transport rate across the mucus barrier and the aqueous boundary layer. Suspensions of nanoparticles also sometimes behave differently than those of larger particles in the fed state. This review compares the absorption mechanisms of nano- and larger particles in the lumen at different prandial states, with an emphasis on data derived from in vivo models. Four BSC class II drugs—aprepitant, cyclosporine, danazol and fenofibrate—are discussed in detail based on information from preclinical intestinal perfusion models.

Abstract
Background Bezafibrate is a BCS class II drug as it presents very low solubility in water; therefore, its bioavailability after oral administration is very poor. The aim of this work was to enhance solubility and dissolution rate of bezafibrate in water in order to enhance its oral bioavailability. Methods Several formulations were prepared using PVP K30 and Cremophor ELP employing the solvent-evaporation method and the electrospraying technique. Solubility, release rate, bioavailability in male Sprague Dawley rats, and lipid profile attributes in Wistar rats were assessed in comparison with bezafibrate plain powder. Solid-state characterization was carried out using X-ray diffraction (XRD) analysis, differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Results All the formulations exerted positive effect towards the desired goal. In particular, the optimized formulation furnished about 14-fold enhanced solubility and 85.48 ± 10.16% drug was released in 10 min as compared with bezafibrate alone (4.06 ± 2.59%). The drug existed in the amorphous state in the prepared sample as confirmed by XRD and DSC, whilst no drug-excipient interactions were observed through FTIR analysis. Moreover, SEM revealed smooth-surfaced spherical particles of the optimized formulation. A 5.5-fold higher oral bioavailability was achieved with the optimized formulation in comparison with bezafibrate plain powder. Also, TG, LDL and TC were decreased, and HDL was increased considerably in HFD-treated rats. Conclusion The optimized formulation consisting of bezafibrate, PVP K30 and cremophor ELP (1/12/1.5, w/w/w) might be a capable drug delivery system for orally administering poorly water-soluble bezafibrate with improved bioavailability and antihyperlipidemic effects.

Abstract
Applications of poorly water-soluble drugs in skin delivery pose several challenges to pharmaceutical formulation. This research originally developed solid lipid nanoparticles (SLNs) packaging a modified core of a solid dispersion (SD) in the lipid matrix to modulate the skin release patterns. Curcumin (CUR) was selected as the poorly water-soluble drug applied in the formulation. The designed system, so-called solid dispersion lipid nanoparticles (SD-SLNs), was fabricated by incorporating a solidifying SD or a non-solidifying SD into the core of the SLNs by ultrasonication. Release studies illustrated an important enhancement in the drug release of the proposed system compared to pure CUR and SLN formulations without the presence of SD as the modified core, which indicated the positive effect of the combined colloidal method of SD and SLNs. The physicochemical properties of the SD-SLN systems were also elucidated using powder X-ray diffraction, Fourier transform infrared spectroscopy, and particle size analysis. The drug was found to change to an amorphous state without any molecular interactions along with a marked particle size reduction. This work demonstrated the strong potential of applying a novel SD-SLN system for the skin delivery of a drug with poor water solubility.

Abstract
Fenofibrate is a peroxisome proliferator-activated receptor α (PPARα) agonist and has been shown to have therapeutic effects on diabetic retinopathy (DR). However, the effects of fenofibrate through systemic administration are not as potent as desired due to inefficient drug delivery to the retina. The present study aimed to explore the sustained therapeutic effects of fenofibrate-loaded biodegradable nanoparticles (NP) on both DR and neovascular age-related macular degeneration (AMD). Fenofibrate was successfully encapsulated into poly(lactic- co-glycolic acid) (PLGA) NP (Feno-NP), and Feno-NP were optimized by varying polymer composition to achieve high drug loading and prolonged drug release. The Feno-NP made of PLGA 34 kDa demonstrated a drug content of 6% w/w and a sustained drug release up to 60 days in vitro. Feno-NP (PLGA 34 kDa) was selected for following in vivo studies, and one single intravitreal (IVT) injection of Feno-NP into rat eyes with a 30G fine needle maintained sustained fenofibric acid drug level in the eye for more than 60 days. The efficacy of Feno-NP in DR and neovascular AMD was investigated using streptozotocin (STZ)-induced diabetic rats, laser-induced choroidal neovascularization (CNV) rats, and very low-density lipoprotein receptor knockout ( Vldlr -/-) mice. Therapeutic effects of Feno-NP were evaluated by measuring electroretinogram (ERG), retinal vascular leakage, leukostasis, CNV size, and retinal levels of vascular endothelial growth factor (VEGF) and intracellular adhesion molecule-1 (ICAM-1). In diabetic rats, Feno-NP ameliorated retinal dysfunctions, reduced retinal vascular leakage, inhibited retinal leukostasis, and downregulated the overexpression of VEGF and ICAM-1 at 8 weeks after one IVT injection. In addition, Feno-NP reduced retinal vascular leakage and CNV formation in both CNV rats and Vldlr -/- mice. Moreover, no toxicity of Feno-NP or Blank-NP to retinal structure and function was detected. Feno-NP exhibited good physiochemical characteristics and controlled drug release profile, conferring prolonged beneficial effects on DR and neovascular AMD.

Abstract
The aim of this work was to develop, optimize and characterize a silymarin-laden polyvinylpyrrolidone (PVP)-polyethylene glycol (PEG) polymeric composite to resolve low aqueous solubility and dissolution rate problem of the drug. A number of silymarin-laden polymeric formulations were fabricated with different quantities of PVP K-30 and PEG 6000 by the solvent-evaporation method. The effect of PVP K-30 and PEG 6000 on the aqueous solubility and dissolution rate was investigated. The optimized formulation and its constituents were characterized using powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques. Both the PEG 6000 and PVP K-30 positively affected the aqueous solubility and dissolution rate of the drug. In particular, a formulation consisting of silymarin, PVP K-30 and PEG 6000 (0.25/1.5/1.5, w/w/w) furnished the highest solubility (24.39±2.95 mg/mL) and an excellent dissolution profile (~100% in 40 min). The solubility enhancement with this formulation was ~1150-fold as compared to plain silymarin powder. Moreover, all the constituents existed in the amorphous state in this silymarin-laden PVP-PEG polymeric composite. Accordingly, this formulation might be a promising tool to administer silymarin with an enhanced effect via the oral route.

Drug Deliv 2017; 24:1018-1025. [PMID: 28675315 PMCID: PMC8240999 DOI: 10.1080/10717544.2017.1344335] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2017] [Revised: 06/08/2017] [Accepted: 06/15/2017] [Indexed: 02/06/2023] Open
Abstract
To develop a novel solid self-nanoemulsifying drug delivery system (S-SNEDDS) for a water-insoluble oily drug, 1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol (PLAG) with improved stability and oral bioavailability, numerous S-SNEDDS were prepared with surfactant, hydrophilic polymer, antioxidant, and calcium silicate (porous carrier) using the spray-drying method. Their physicochemical properties were evaluated using emulsion droplet size analysis, SEM and PXRD. Moreover, the solubility, dissolution, stability, and pharmacokinetics of the selected S-SNEDDS were assessed compared with the drug and a commercial soft capsule. Sodium lauryl sulfate (SLS) and hydroxypropyl methylcellulose (HPMC) with the highest drug solubility were selected as surfactant and hydrophilic polymer, respectively. Among the antioxidants tested, only butylated hydroxyanisole (BHA) could completely protect the drug from oxidative degradation. The S-SNEDDS composed of PLAG/SLS/HPMC/BHA/calcium silicate at a weight ratio of 1: 0.25: 0.1: 0.0002: 0.5 provided an emulsion droplet size of less than 300 nm. In this S-SNEDDS, the drug and other ingredients might exist in the pores of carrier and attach onto its surface. It considerably improved the drug stability (about 100 vs. 70%, 60 °C for 5 d) and dissolution (about 80 vs. 20% in 60 min) compared to the commercial soft capsule. Moreover, the S-SNEDDS gave higher AUC, Cmax, and Tmax values than the commercial soft capsule; in particular, the former improved the oral bioavailability of PLAG by about 3-fold. Our results suggested that this S-SNEDDS provided excellent stability and oral bioavailability of PLAG. Thus, this S-SNEDDS would be recommended as a powerful oral drug delivery system for an oily drug, PLAG.

Novel electrosprayed nanospherules for enhanced aqueous solubility and oral bioavailability of poorly water-soluble fenofibrate. Int J Nanomedicine 2016; 11:213-21.

Abstract
Purpose The purpose of the present research was to develop a novel electrosprayed nanospherule providing the most optimized aqueous solubility and oral bioavailability for poorly water-soluble fenofibrate. Methods Numerous fenofibrate-loaded electrosprayed nanospherules were prepared with polyvinylpyrrolidone (PVP) and Labrafil® M 2125 as carriers using the electrospray technique, and the effect of the carriers on drug solubility and solvation was assessed. The solid state characterization of an optimized formulation was conducted by scanning electron microscopy, powder X-ray diffraction, differential scanning calorimetry, and Fourier transform infrared spectroscopic analyses. Oral bioavailability in rats was also evaluated for the formulation of an optimized nanospherule in comparison with free drug and a conventional fenofibrate-loaded solid dispersion. Results All of the electrosprayed nanospherule formulations had remarkably enhanced aqueous solubility and dissolution compared with free drug. Moreover, Labrafil M 2125, a surfactant, had a positive influence on the solubility and dissolution of the drug in the electrosprayed nanospherule. Increases were observed as the PVP/drug ratio increased to 4:1, but higher ratios gave no significant increases. In particular, an electrosprayed nanospherule composed of fenofibrate, PVP, and Labrafil M 2125 at the weight ratio of 1:4:0.5 resulted in a particle size of <200 nm with the drug present in the amorphous state. It demonstrated the highest solubility (32.51±2.41 μg/mL), an excellent dissolution (~85% in 10 minutes), and an oral bioavailability ~2.5-fold better than that of the free drug. It showed similar oral bioavailability compared to the conventional solid dispersion. Conclusion Electrosprayed nanospherules, which provide improved solubility and bioavailability, are promising drug delivery tools for oral administration of poorly water-soluble fenofibrate.
