Heliyon 2024; 10:e35069. [PMID: 39170221 PMCID: PMC11336325 DOI: 10.1016/j.heliyon.2024.e35069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2024] [Revised: 07/19/2024] [Accepted: 07/22/2024] [Indexed: 08/23/2024] Open
Abstract
The utilization of phytoconstituents in skin care products has emerged as a notable trend due to their recognized safety and therapeutic efficacy. However, the challenge lies in improving the effective delivery of phytoconstituents to specific tissues, primarily attributed to their poor solubility and low permeability. This study endeavors to address this challenge by developing, optimizing and characterizing Cucumis melo var. agrestis (CME) extract loaded nanoemulsion gel (CME-NEG), aiming to enhance the skin permeability and antifungal activity. Herein, nanoemulsions encapsulating the plant extract were prepared using ultrasonication technique and were characterized for droplet size, zeta potential, polydispersity index (PDI) and entrapment efficiency. Further, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analysis were conducted to characterize the optimized CME extract loaded nanoemulsion (CME-NE 3) formulation. The optimized formulation was blended with Carbopol 940 gel to develop CME-NEG, which was evaluated for release kinetics, in vitro permeation and in vitro antifungal activity. High performance liquid chromatography (HPLC) analysis confirmed the presence of gallic acid, chlorogenic acid, 4-Hydroxy benzoic acid (HB acid), kaempferol, caffeic acid and quercetin. Findings of 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay showed that the ethanolic extract had highest antioxidant activity (88.88 %). The optimized formulation displayed smooth spherical nanodroplets with size of 175.5 ± 1.56 nm, zeta potential of -21.5 ± 0.12 mV, PDI of 0.192 ± 0.06, and highest entrapment efficiency (EE) of 91.35 ± 1.65 %. The release profile of CME-NE exhibited a controlled release characteristic and the release kinetic mechanism was best described by the Korsmeyer-Peppas (Kp) model. In a 24 h permeation study, it was observed that the in vitro permeation of CME-NEG was 58.63 %, significantly higher than that of CME extract loaded plain gel (CME-PG) with an enhancement ratio of 2.12. The prepared CME-NEG formulation also presented enhanced antifungal activity as compared to pure CME extract. In conclusion, the designed CME-NEG offers a promising topical drug delivery system with enhanced skin permeability and antifungal activity.

Abstract
The objective of this study was to evaluate the antifungal activity of free methyl 3,5 dinitrobenzoate (MDNB) and its nanoemulsion (MDNB-NE) against strains of Candida albicans. Additionally, a molecular modeling study was also carried out to propose the mechanism of action and toxicity of MDNB. These results demonstrated the MDNB-NE presented a droplet size of 181.16 ± 3.20 nm and polydispersity index of 0.30 ± 0.03. MDNB and MDNB-NE inhibited the growth of all strains with minimum inhibitory concentrations of 0.27-1.10 mM. The biological results corroborated the molecular model, which pointed to a multi-target antifungal mechanism of action for MDNB in C. albicans. The study could serve as a basis for further research involving compounds with nitro groups with antifungal.

Abstract
The objective of this study was to explore the benefits of transdermal drug delivery systems as an alternative option for patients who are unable to tolerate oral administration of drugs, such as ibuprofen (IB). To achieve this, nonionic surfactants and three cosolvents were employed to develop new microemulsions (MEs) that contained IB as nanocarriers. The aim was to enhance the solubility and bioavailability of the drug after transdermal administration. The MEs were characterised by droplet size, polydispersity index (PDI), and rheological properties. Furthermore, the flux of IB was evaluated by Franz diffusion cells using excised rat skin and in vivo bioavailability using rats. The results showed that the MEs had ideal viscosity and droplet size below 100 nm. Moreover, using the developed MEs, an improvement in the solubility (170 mg/mL) and flux through the rat skin (94.6 ± 8.0 µg/cm2.h) was achieved. In addition, IB demonstrated a maximum plasma level of 0.064 mg/mL after 8 h of transdermal administration in rats using the ME with an increase in the bioavailability of about 1.5 times in comparison to the commercial IB gel. In conclusion, the developed nonionic MEs containing IB can be ideal nanocarriers and promising formulations for the transdermal administration of IB.

Abstract
This study aimed to prepare an o/w mitiglinide microemulsion (MTGME) to improve the drug solubility and bioavailability. The formulation of o/w MTGME was optimized by the solubility study of drug, pseudo-ternary phase diagram and Box-Behnken design successively. MTGME was characterized by dynamic laser light scattering (DLS), zeta potential and transmission electron microscopy (TEM), moreover, the storage stability, pharmacodynamics and pharmacokinetics were investigated. The optimal prescription for MTGME consisted of Maisine 35-1 (oil), Cremophor EL (surfactant) and propylene glycol (PG, cosurfactant). MTGME with a spherical dimension of 58.1 ± 5.86 nm was stable when stored at 4 °C for 3 months. The blood glucose levers (BGL) of diabetic mice were uniformly and significantly decreased by intragastric (i.g.) administration of 1-4 mg/kg MTGME, in which BGL (i.g. 4 mg/kg MTGME) was reduced by 69% during 24 h. The pharmacokinetics study of MTGME (i.g., 20 mg/kg) in Wistar rats showed higher plasma drug concentration (Cmax, 2.9 folds), larger area under curve (AUC, 4.6 folds) and oral bioavailability than those of MTG suspensions. Generally, the MTGME (o/w) showed good effect on controlling hyperglycemia. Therefore, microemulsion can be used as an effective oral drug delivery system to improve the bioavailability of MTG.

SCIENTIFICA 2023; 2023:6640103. [PMID: 37928749 PMCID: PMC10625491 DOI: 10.1155/2023/6640103] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 10/02/2023] [Accepted: 10/13/2023] [Indexed: 11/07/2023]
Abstract
The pharmaceutical sector has made considerable strides recently, emphasizing improving drug delivery methods to increase the bioavailability of various drugs. When used as a medication delivery method, nanoemulsions have multiple benefits. Their small droplet size, which is generally between 20 and 200 nanometers, creates a significant interfacial area for drug dissolution, improving the solubility and bioavailability of drugs that are weakly water-soluble. Additionally, nanoemulsions are a flexible platform for drug administration across various therapeutic areas since they can encapsulate hydrophilic and hydrophobic medicines. Nanoemulsion can be formulated in multiple dosage forms, for example, gels, creams, foams, aerosols, and sprays by using low-cost standard operative processes and also be taken orally, topically, topically, intravenously, intrapulmonary, intranasally, and intraocularly. The article explores nanoemulsion formulation and production methods, emphasizing the role of surfactants and cosurfactants in creating stable formulations. In order to customize nanoemulsions to particular medication delivery requirements, the choice of components and production techniques is crucial in assuring the stability and efficacy of the finished product. Nanoemulsions are a cutting-edge technology with a lot of potential for improving medication bioavailability in a variety of therapeutic contexts. They are a useful tool in the creation of innovative pharmaceutical formulations due to their capacity to enhance drug solubility, stability, and delivery. Nanoemulsions are positioned to play a crucial role in boosting medication delivery and enhancing patient outcomes as this field of study continues to advance.

Abstract
Background: The nonsteroidal anti-inflammatory medication meloxicam (MLX) belongs to the oxicam family and is used to reduce inflammation and pain. The aim of this study was to improve MLX's dispersibility and stability by producing it as a liquid self-microemulsifying drug delivery system since it is practically insoluble in water. Methods: Five different formulations were made by adjusting the amounts of propylene glycol, Transcutol P, Tween 80, and oleic acid oil and establishing a pseudo-ternary diagram in ratios of 1:1, 1:2, 1:3, 1:4, and 3:4, respectively. All of the prepared formulations were tested for a variety of properties, including thermodynamic stability, polydispersity index, particle size distributions, dilution resistance, drug contents, dispersibility, in vitro solubility of the drug, and emulsification time. Results: F5 was chosen as the optimal MLX liquid self-microemulsion due to its higher drug content (99.8%), greater in vitro release (100% at 40 min), smaller droplet size (63 nm), lower polydispersity index (PDI) value (0.3), and higher stability (a zeta potential of -81 mV). Conclusions: According to the data provided here, the self-microemulsifying drug delivery system is the most practical method for improving the dispersibility and stability of MLX.

Abstract
INTRODUCTION Oral administration of poorly water-soluble drugs (PWSDs) is generally related to low bioavailability, leading to high drug doses, multiple side effects, and low patient compliance. Thus, different strategies have been developed to increase drug solubility and dissolution in the gastrointestinal tract, opening new venues for these drugs. AREAS COVERED This review outlines the current challenges in PWSD formulation development and the strategies to overcome the oral barriers and increase their solubility and bioavailability. Conventional strategies include altering crystalline and molecular structures and modifying oral solid dosage forms. In contrast, novel strategies comprise micro- and nanostructured systems. Recent representative studies involving how these strategies have improved the oral bioavailability of PWSDs were also reviewed and reported. EXPERT OPINION New approaches to enhance PWSD bioavailability have sought to improve water solubility and dissolution rates, drug protection by overcoming biological barriers, and increased absorption. Still, only a handful of studies have focused on quantifying the increase in bioavailability. Improving the oral bioavailability of PWSDs remains an exciting unexplored field of research and has become an important issue for successfully developing pharmaceutical products.

Abstract
Background: Quercetin (QCT) is a natural polyphenolic flavonoid showing great potential in the treatment of skin cancer. However, its use is limited owing to its poor water solubility, poor absorption, quick metabolism and excretion, as well as low stability. Preparation of nanoemulgel has been proven to be an effective approach to deliver the drugs topically due to various advantages associated with it. Objectives: This study aimed to prepare stable nanoemulgel of QCT using a Design-of-Experiments (DoE) tool for optimization, to characterize and to assess its in vivo toxicity and efficacy against human cancer cell lines in vitro. Methods: An ultrasonication emulsification method was used for the preparation of QCT-loaded nanoemulsion (QCT@NE). Box-Behnken design was used for the optimization of developed nanoemulgel. Then, in vitro characterization of prepared nanoemulsion was performed using Fourier Transform-Infra Red (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM), particle size analysis, determination of zeta potential and entrapment efficiency (%EE). Further, the developed QCT-loaded nanoemulgel (QCT@NG) was characterized in vitro using texture profile analysis, viscosity and pH determination. Eventually, the cell cytotoxicity studies of the prepared nanoemulgel were performed on the skin cancer cell lines A431 followed by an acute toxicity and skin irritation study on male wistar rats in vivo. Results: The developed QCT@NE was found to be nanometric in size (173.1 ± 1.2 nm) with low polydispersity index (0.353 ± 0.13), zeta potential (-36.1 ± 5.9 mV), and showed good %EE (90.26%). The QCT@NG was found to be substantially more effective against the human skin carcinoma (A431) cell lines as compared to plain QCT with IC50 values of 108.5 and 579.0 µM, respectively. Skin irritation study showed no sign of toxicity and ensured safety for topical application. Hematological analysis revealed no significant differences between the treatment and control group in any biochemical parameter. In the nanoemulgel treatment group, there were no discernible differences in the liver enzymes, bilirubin, hemoglobin, total leukocyte and platelet counts as compared to the control group. Conclusions: The optimized QCT@NG was found to be an ideal and promising formulation for the treatment of skin cancer without showing skin irritation and organ toxicity.

Abstract
The oral route is the most common and practical means of drug administration, particularly from a patient’s perspective. However, the pharmacokinetic profile of oral drugs depends on the rate of drug absorption through the intestinal wall before entering the systemic circulation. However, the enteric epithelium represents one of the major limiting steps for drug absorption, due to the presence of efflux transporters on the intestinal membrane, mucous layer, enzymatic degradation, and the existence of tight junctions along the intestinal linings. These challenges are more noticeable for hydrophilic drugs, high molecular weight drugs, and drugs that are substrates of the efflux transporters. Another challenge faced by oral drug delivery is the presence of first-pass hepatic metabolism that can result in reduced drug bioavailability. Over the years, a wide range of compounds have been investigated for their permeation-enhancing effect in order to circumvent these challenges. There is also a growing interest in developing nanocarrier-based formulation strategies to enhance the drug absorption. Therefore, this review aims to provide an overview of the challenges faced by oral drug delivery and selected strategies to enhance the oral drug absorption, including the application of absorption enhancers and nanocarrier-based formulations based on in vitro, in vivo, and in situ studies.

[PMID: 34961897 PMCID: PMC8816498 DOI: 10.1208/s12249-021-02176-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 11/03/2021] [Indexed: 11/30/2022] Open
Abstract
The present study focused on establishing a novel, (pre-)screening approach that enables the development of promising performing self-nanoemulsifying drug delivery systems (SNEDDSs) with a limited number of experiments. The strategic approach was based on first identifying appropriate excipients (oils/lipids, surfactants, and co-solvents) providing a high saturation solubility for lipophilic model compounds with poor aqueous solubility. Excipients meeting these requirements were selected for SNEDDS development, and a special triangular mixture design was applied for determining excipient ratios for the SNEDDS formulations. Celecoxib and fenofibrate were used as model drugs. Formulations were studied applying a specific combination of in vitro characterization methods. Specifications for a promising SNEDDS formulation were self-imposed: a very small droplet size (< 50 nm), a narrow size distribution of these droplets (PDI < 0.15) and a high transmittance following SNEDDS dispersion in water (> 99% in comparison with purified water). Excipients that provided a nanoemulsion after dispersion were combined, and ratios were optimized using a customized mapping method in a triangular mixture design. The best performing formulations were finally studied for their in vitro release performance. Results of the study demonstrate the efficiency of the customized screening tool approach. Since it enables successful SNEDDS development in a short time with manageable resources, this novel screening tool approach could play an important role in future SNEDDS development.

Abstract
Letrozole (LZ) is an aromatase inhibitor, which inhibits the formation of estrogens from androgens. Nanoemulsion is a liquid emulsion formulation utilized to increase solubility, bioavailability, and drug delivery to cancer cells. This study aims to improve LZ oral delivery through formulating solid nanoemulsion (SNE). Peppermint oil, tween 80, and transcutol P were used as an oil, surfactant, and co-surfactant, respectively. The optimized nanoemulsion (NE-3) was then incorporated into solid polyethylene glycol (PEG) to formulate (SNE). The optimized (NE-3), SNE-2, and the available marketed tablet have been compared. The optimized (NE-3) was selected according to specific parameters of optimum small nano-size 80 nm, PDI of 0.181, the zeta potential of-98.2, high transmittance (99.78%), optimum pH (5.6), a high percent of LZ content (99.03 ± 1.90), the relatively low viscosity of 60.2 mPa.s, and a rapid release of LZ within 30 min. NE-3 was selected to be formulated as SNE. LZ's best release rate was 80% in 5 min with a content homogeneity of 99.85 ± 0.04 for SNE-2. Zero-order kinetics is determined to have the greatest R2 values. Field emission scanning electron microscopy (FE-SEM) detected that SNE-2 was (36.75-96.64 nm) with a spherical form and no adhesion or aggregation. FT-IR showed no significant variations in position and shape of the absorption peaks between the pure drug and optimal formulation diagrams. This novel nanoemulsion technology aids in improving the solubility of poorly water-soluble drugs, particularly the SNE delivery method, which has a higher in-vitro release rate and expiration date of LZ than others.

Abstract
Nanodelivery of drugs aims to ensure drug stability in the face of adverse biochemical conditions in the course of administration, concomitant with appropriate pharmacological action provided by delivery at the targeted site. In this study, the application potential of a nanoparticle produced with biopolymers chitosan-N-arginine and alginate as an oral drug delivery material is evaluated. Both macromolecules being weak polyelectrolytes, the nanoparticle presents strong thermodynamic interactions with a biological model membrane consisting of a charged lipid liposome bilayer, leading to membrane disruption and membrane penetration of the nanoparticles in ideal conditions of pH corresponding to the oral route. The powder form of the nanoparticle was obtained by lyophilization and with a high percentage of entrapment of the anthelmintic drug praziquantel. In vivo studies were conducted with oral administration to Corydoras schwartzi fish with high intensity of intestinal parasites infection. The in vivo experiments confirmed the mucoadhesive and revealed membrane-penetrating properties of the nanoparticle by translocating the parasite cyst, which provided target drug release and reduction of over 97% of the fish intestinal parasites. Thus, it was evidenced that the nanoparticle was effective in transporting and releasing the drug to the target, providing an efficient treatment.

Abstract
OBJECTIVE The aim of this study was to develop a pediatric oral preparation for ibuprofen. SIGNIFICANCE Ibuprofen is widely used for defervescence in children, but medication compliance is poor due to its bitter taste. Dry emulsions possess good stability and can be transported and stored in solid form; they can be dispersed into liquid emulsions with water and easily administered to children. METHODS In this study, a dry emulsion excipient was prepared by spray drying: a mixture of orange peel and corn oils (3:7, w/w) was used as the oil phase and solvent for ibuprofen; gum arabic and gum tragacanth were chosen as emulsifiers; and maltodextrin was used as a solid carrier. RESULTS The particle sizes of the liquid and reconstituted emulsions were 5.75 µm and 6.11 µm, respectively; the average particle size distribution of the dry emulsion powder was 8.13 µm; scanning electron microscopy showed that the dry emulsion powder was composed of evenly distributed smooth spheres. At a drug loading of 36.52 ± 1.15 mg/g, 90% of ibuprofen was released from the dry emulsion excipient within 30 min. Sensory evaluations using human volunteers, rats, and an electronic tongue demonstrated that the emulsion had a taste-masking effect on ibuprofen. It was further corroborated by in vivo studies using a rat model that highlighted a 1.76-fold increase in ibuprofen absorption when the drug was administered as an emulsion compared with granules. CONCLUSIONS These results indicate that the dry emulsion for taste-masking is promising and valuable in the development of ibuprofen for pediatrics.

Aspirin and omega-3 polyunsaturated fatty acid use and their interaction in cardiovascular diseases and colorectal adenomas. Nutr Res Rev 2021; 35:295-307.

Abstract
Aspirin (acetylsalicylic acid, ASA) is inexpensive and is established in preventing cardiovascular disease (CVD) and colorectal adenomas. Omega-3 (n3) polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have also shown benefit in preventing CVD. The combination could be an effective preventative measure in patients with such diseases. ASA and n3 PUFA reduced the risk of CVD in ASA-resistant or diabetic patients. EPA- and DHA-deficient patients also benefited the most from n3 PUFA supplementation. Synergistic effects between ASA and EPA and DHA are 'V-shaped' such that optimal ASA efficacy is dependent on EPA and DHA concentrations in blood. In colorectal adenomas, ASA (300 mg/d) and EPA reduced adenoma burden in a location- and subtype-specific manner. Low doses of ASA (75-100 mg/d) were used in CVD prevention; however, ultra-low doses (30 mg/d) can also reduce thrombosis. EPA-to-DHA ratio is also important with regard to efficacy. DHA is more effective in reducing blood pressure and modulating systemic inflammation; however, high-dose EPA can lower CVD events in high-risk individuals. Although current literature has yet to examine ASA and DHA in preventing CVD, such combination warrants further investigation. To increase adherence to ASA and n3 PUFA supplementation, combination dosage form may be required to improve outcomes.

Abstract
The majority of newly developed drugs need to be incorporated with delivery systems to maximize their effect and minimize side effects. Nanoemulsions (NEs) are one type of delivery system that helps to improve the solubility and dissolution of drugs, attempting to enhance their bioavailability and onset of action. The objective of this investigation was to develop an omega-3 oil-based NE loaded with loxoprofen (LXP) to enhance its dissolution, in vitro release, and mucosal penetration and decrease its mucosal ulcerative effects when applied in an oral treatment. LXP-loaded NEs were formulated with varying levels of omega-3 oil (10–30%), surfactant polyoxyethylene-C21-ethers (laureth-21) (40–60%), and co-surfactant polyethylene glycol-40 hydrogenated castor oil (HCO-40) (30–50%) using an extreme vertices mixture design. The developed NEs were characterized for globule size and drug loading capacity. The optimal formulation was tested for in vitro drug release, ex vivo permeation, and ulcer index value. The developed NE acquired a globule size ranging 71–195 nm and drug loading capacity of 43–87%. Considering the results of the in vitro release study, the optimized NE formulation achieved 2.45-fold and 2-fold increases in drug permeation across tested mucosa compared to a marketed tablet and drug aqueous dispersion, respectively. Moreover, the optimum NE exhibited the best ulcer index in comparison to drug aqueous suspension and different formulations when tested in rats. Overall, this research highlights the capacity of NEs to deliver LXP with enhanced solubility, drug release, and permeation while effectively protecting the application site from side effects of the model drug.
