Dissolution and antioxidant potential of apigenin self nanoemulsifying drug delivery system (SNEDDS) for oral delivery

Self-nanoemulsifying drug delivery systems (SNEDDS) have been used to improve the oral bioavailability of various drugs. In the current study, apigenin was developed as SNEDDS to solve its dissolution problem and enhance oral bioavailability and antioxidant potential. SNEDDS were prepared by mixing Gelucire 44/14, Tween 80, and PEG 400 under controlled conditions. The droplet of diluted SNEDDS demonstrated a spherical shape with a size of less than 100 nm and a neutral charge. The very fast self-emulsification was obtained within 32 s, and the transmittance values exceeded 99%. The highest drug loading was 90.10 ± 0.24% of the initial load with the highest %encapsulation efficiency of 84.20 ± 0.03%. FT-IR and DSC spectra showed no interaction between components. The dissolution in buffer pH 1.2, 4.5, and 6.8 showed significantly higher dissolved apigenin than the apigenin coarse powder. The dissolution profiles were fitted to the Korsmeyer–Peppas kinetics. The cellular antioxidant activities in Caco-2 cells were approximately 52.25–54.64% compared to no treatment and were higher than the apigenin coarse powder (12.70%). Our work highlights the potential of SNEDDS to enhance the dissolution and permeability of apigenin and promote antioxidant efficacy, which has a strong chance of being developed as a bioactive compound for nutraceuticals.

Enhancing the Antiproliferative Activity of Perillyl Alcohol against Glioblastoma Cell Lines through Synergistic Formulation with Natural Oils.

Due to its volatility, photostability, and gastrointestinal toxicity, Perillyl Alcohol (POH), a monoterpenoid component of various plant species, is a chemotherapeutic drug with insufficient efficacy. Many naturally occurring bioactive compounds have well-known antiproliferative properties, including sefsol, jojoba, tea tree, and moringa oils. This study sought to develop an oil-based Self Nanoemulsifying Drug Delivery System (SNEDDS) using tween 80 as the surfactant and Dimethyl Sulfoxide (DMSO) or Polyethylene Glycol (PEG) 400 as the cosurfactant; the oils were used in a range of 10-20% to boost POH's anticancer efficacy. The formulations' size, charge, and impact on the viability of glioma cell lines, ANGM-CSS and A172, were evaluated. The developed SNEDDS formulations ranged from 3 nm to 362 nm in size, with electronegative surface charges between 5.05 and 17.0 mV and polydispersity indices between 0.3 and 1.0. The findings indicated that the antiproliferative effect of POH-loaded Nanoemulsion (NE) could be used as a possible anticancer therapy for glioblastoma in vitro, particularly when paired with the tested natural oils. Before asserting that this delivery technique is appropriate for glioblastoma therapy, additional in vitro and in vivo investigations are required.

Triamcinolone-loaded self nano-emulsifying drug delivery systems for ocular use: An alternative to invasive ocular surgeries and injections

Inflammation of the posterior segment of the eye is a severe condition and hard to cure as delivery of drugs to the inflammation site is inefficient. Currently, the primary treatment approach is ocular surgery or invasive ocular injections. Herein, we designed and developed a topically self nano-emulsifying drug delivery system (SNEDDs) to deliver triamcinolone acetonide (TCA) to the posterior segment of the eye. A screening based on TCA solubility was conducted on each excipient followed by preparation of various formulations using different ratios of the selected excipients. Vesicles of optimized SNEDDs had less than 100 nm size and spherical morphology. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay showed self-emulsified vesicles have relatively high safety on retinal pigment epithelium (RPE) cell line. Furthermore, efficient cellular uptake of coumarin 6-loaded SNEDDs in RPE using confocal laser scanning microscopy (CLSM) was confirmed.In addition, an in-vivo study using hematoxylin and eosin (H&E) staining revealed that 14 days of topical treatment of albino rabbit eyes with TCA-loaded SNEDDs was safe and no sign of tissue destruction and inflammation was detected in different parts of the eye sections including cornea, sclera, retina, and optic nerve. Also, the CLSM images from topically treated eyes with coumarin 6 (a hydrophobic, fluorescent drug model) loaded SNEDDs, showed that the optimized SNEDDs could properly penetrate toward the posterior segments of the eye especially the retina, posterior parts of the choroid, and sclera. Considering the outstanding results obtained by ocular tissue penetration and low toxicity, prepared SNEDDs, have the potential to be used as a topical administration for treating posterior segment disorders of the eye through an utterly non-invasive route and TCA-loaded SNEDDs could be an alternative for TCA intravitreal and intra conjunctival injections.

Dihydroquercetin has been documented to have powerful antioxidant activity and many beneficial properties for human health, especially its ability to inhibit certain types of cancer cells. However, its low solubility and bioavailability are major obstacles to biomedical applications. Moreover, DHQ is chemically unstable and quickly degrades when exposed to alkaline conditions. Objective: In the present study, a DHQ nanoemulsion formulation was prepared by Self Nano- Emulsifying Drug Delivery System (SNEDDS) technique to overcome the above disadvantages. Methods: The obtained nanoemulsion system was evaluated for its micro-properties, stability, and in vitro cytotoxic activity against some cancer cells using tetrazolium dyes (MTS assay). Results: Measurement results showed that the DHQ nanoemulsion was successfully synthesized with typical mean droplet sizes from 9 to 11 nm, and revealed excellent stability over time. Dihydroquercetin in nanoemulsion form is more stable than the non-encapsulated form, as evidenced by the maintenance of droplet size in the nanometer range when dispersed in aqueous solution for up to 48 hours. This stability is particularly pronounced in both acidic and neutral environments. In vitro experiments on cytotoxic activities against A549, Hela, and HepG2 cancer cell lines indicated that the prepared DHQ nanoemulsion effectively inhibited the growth of all these cell lines with IC50 values (μg/mL) of 8.0, 20.4, and 29.5 respectively. Conclusion: From the detailed results above, it is evident that the solubility and bioavailability of DHQ can be improved by creating its nanostructure in the form of nanoemulsions. Furthermore, the nano form of DHQ carried within stable nanoemulsions exhibited better performance in inhibiting cancer cells compared to free DHQ. Therefore, further research is required to explore the development of cancer therapeutics utilizing nano DHQ emulsions.

Nanoemulsion drug delivery system loaded with imiquimod: a QbD-based strategy for augmenting anti-cancer effects

BackgroundSkin cancer is becoming a public health concern due to increased exposure to environmental pollutants and UV rays, among other factors. In India, skin neoplasms constitute 2–3% of all human cancer cases, whereas in the USA, 2–3 million cases of non-melanoma skin cancer are reported annually. Various drugs are available in the market for treating skin cancer. Imiquimod (IMQ) is one such drug approved by the USFDA for managing basal cell malignancy, external genital warts, and actinic keratosis. The conventional dosage form of IMQ cream has several side effects that can lead to therapy interruption. Therefore, the present work aims to develop an IMQ nanoemulsion with improved solubility, in vitro drug release and stability. Nanoemulsion was formulated using oleic acid/rose oil, with polysorbate 20/propylene glycol selected as the oil phase and Smix, respectively. Optimization carried out using a 32 factorial design with the aid of a quadratic model. Characterization was conducted for parameters, namely viscosity, pH, drug content, globule size, zeta potential and entrapment efficiency. Thermodynamic stability studies were conducted to assess the stability of the formulation. Furthermore, the optimized system was subjected to TEM analysis, in vitro drug release and in vitro cytotoxicity assay (MTT assay).ResultsNanoemulsions were found to be in the size range of 152.80–470.13 nm and exhibited a spherical shape. Zeta potential values ranged from − 28.93 to − 58.48 mV. DSC measurements indicated the complete solubilization of IMQ in the nanoemulsion system. The optimized formulation F1 displayed the following characteristics: a globule size < 200 nm, a zeta potential > − 55 mV, a polydispersity index < 0.2, % drug content of 102.89 ± 1.06, % entrapment efficiency of 97.59 ± 0.24, a pH of 4.77 ± 0.06, and a viscosity of 4.06 ± 0.06 poise. In vitro IMQ release studies of nanoemulsion and commercial cream showed approximately 70% and 34% drug release, respectively, at the end of 8 h. Moreover, the in vitro cytotoxicity assay depicted that F1 exhibited greater cytotoxic potential compared to the commercial formulation against the A431 cell line.ConclusionThe present investigation showed a significant improvement in in vitro drug release of the BCS class IV drug IMQ and enhanced cytotoxic activity against cancerous cells. IMQ-loaded nanoemulsion represents a promising vehicle for delivering treatment to the skin for treating skin cancer.Graphical abstract

Itraconazole Self-Nano Emusifying Drug Delivery System for Enhancement of Solubility

The main objective of formulation is to enhance the bioavailability of the drug within the body. Some of the challenging subjects associated with poorly water-soluble drugs concern solubility and bioavailability factors. To overcome these problems, new technologies, such as lipid-based drug delivery systems including micro or nano emulsifying drug delivery system, have obtained importance in recent years, due to their enhanced solubility and bioavailability in the gastrointestinal tract. Such systems are solubilized within the lipid excipients or mixed with oils or surfactants/co-solvents to facilitate the solubility and absorption rate, which can enhance the bioavailability of the targeted drug. The research was targeted to develop a self-Nano Emulsifying drug delivery system (SNEDDS) for oral bioavailability enhancement of BCS II antifungal drug Itraconazole. Nano Emulsions are consignment methods that improve the solubility and distribution of lipid medicines to the intended areas. SNEDDS of Itraconazole were developed using Castor oil, Tween 20 as surfactant and PEG 200 as co-surfactant. SNEDDS formulation can be obtained through phase diagram approach. Pseudo Ternary phase diagrams were constructed, using Chemix software, to optimize the concentrations of excipients. Thermodynamic stability studies were satisfactory. Robustness to dilution did not exhibit phase separation and drug precipitation. The Among 4 formulations, B1F3 formulation showed more than 95% of drug content and were considered superior and subjected to droplet size analysis and zeta potential measurement. Droplet size ranged from 120 nm to 505 nm. The Nano size was obtained for formulation. The zeta-potential results indicated the range -35 mV. Based on all evaluation tests, formulation B2F3 was chosen as the best. Thus, this self-Nano Emulsifying drug delivery system should be an effective oral dosage form for improving oral bioavailability of lipophilic drug Itraconazole.

Impact of carrier hydrophilicity on solid self nano-emulsifying drug delivery system and self nano-emulsifying granule system

The purpose of this study was to investigate the impact of carrier hydrophilicity on solid self nano-emulsifying drug delivery system (SNEDDS) and self nano-emulsifying granule system (SEGS). The mesoporous calcium silicate (Ca-silicate) and hydroxypropyl-β-cyclodextrin (HP-β-CD) were utilised as hydrophobic carrier and hydrophilic carrier, respectively. The liquid SNEDDS formulation, composed of Tween80/Kollipohr EL/corn oil (35/50/15%) with 31% (w/w) dexibuprofen, was spray-dried and fluid-bed granulated together with Avicel using Ca-silicate or HP- β-CD as a solid carrier, producing four different solid SNEDDS and SEGS formulations. Unlike the Ca-silicate-based systems, spherical shape and aggregated particles were shown in HP-β-CD-based solid SNEDDS and SEGS, respectively. Molecular interaction was detected between Ca-silicate and the drug; though, none was shown between HP-β-CD and the drug. Each system prepared with either carrier gave no significant differences in micromeritic properties, crystallinity, droplet morphology, size, dissolution and oral bioavailability in rats. However, the HP-β-CD-based system more significantly improved the drug solubility than did the Ca-silicate-based system. Therefore, both carriers hardly affected the properties of both solid SNEDDS and SEGS; though, there were differences in the aspect of appearance, molecular interaction and solubility.

Enhancement of Icariin Aphrodisiac Effect by Solid-SNEDDS Method Using Shark Liver Oil Phase

The Epimedium brevicornu Maxim plant contains icariin, a flavonoid compound known for its aphrodisiac effects. However, icariin has low solubility and bioavailability. This study aims to find the best formula for S-SNEDDS icariin, its physical properties, characteristics, and aphrodisiac activity. Using the S-SNEDDS (Solid-Self Nanoemulsifying Drug Delivery System) method with shark liver oil phase is expected to increase the solubility and bioavailability of icariin. The optimum formula used is tween 80 (72.5%): PEG 400 (13.75%) and shark liver oil (13.75%). The optimal formula of S-SNEDDS icariin with the adsorption method to solid carriers requires aerosol 200 as much as 783±28.86mg per 1mL. S-SNEDDS icariin has characteristics with an average emulsification time of 12.88±0.26 seconds, transmittance value of 98.08±0.94%, droplet size 171.8±8.9 nm, zeta potential -35.2±1.1 mV, flow speed less than 10 seconds, resting angle 35.159°. The dissolution test of S-SNEDDS icariin is better than icariin instead of S-SNEDDS. S-SNEDDS icariin dose 50 mg/KgBW has a better aphrodisiac effect than pure icariin 100 mg/kgBW.

Oral hydrogel nanoemulsion co-delivery system treats inflammatory bowel disease via anti-inflammatory and promoting intestinal mucosa repair

BackgroundDue to oral nano-delivery systems for the treatment of inflammatory bowel disease (IBD) are often failed to accumulated to the colonic site and could not achieve controlled drug release, it’s urgent to develop a microenvironment responsive drug delivery to improve therapy efficacy. Inflammation at the IBD site is mainly mediated by macrophages, which are the key effector cells. Excessive inflammation leads to oxidative stress and intestinal mucosal damage. The use of curcumin (CUR) and emodin (EMO) together for the treatment of IBD is promising due to their respective anti-inflammatory and intestinal mucosal repair effects. In view of the pH gradient environment of gastrointestinal tract, here we prepared pH-responsive sodium alginate (SA) hydrogel-coated nanoemulsions to co-deliver CUR and EMO (CUR/EMO NE@SA) to achieve controlled drug release and specifically target macrophages of the colon.ResultsIn this study, a pH-responsive CUR/EMO NE@SA was successfully developed, in which the CUR/EMO NE was loaded by chitosan and further crosslinked with sodium alginate. CUR/EMO NE@SA had a pH-responsive property and could achieve controlled drug release in the colon. The preparation could significantly alleviate and improve the colon inflammatory microenvironment by decreasing TNF-α and IL-6 expression, increasing IL-10 expression, scavenging reactive oxygen species in macrophages, and by ameliorating the restoration of intestinal mucosal tight junction protein expression. Furthermore, we revealed the molecular mechanism of the preparation for IBD treatment, which might due to the CUR and EMO synergic inhibition of NF-κB to improve the pro-inflammatory microenvironment. Our study provides a new IBD therapy strategy via synergically inhibiting inflammatory, repairing mucosal and clearing ROS by pH-sensitive hydrogel-encapsulated nanoemulsion drug delivery system, which might be developed for other chronic inflammatory disease treatment.ConclusionsIt’s suggested that pH-sensitive hydrogel-coated nanoemulsion-based codelivery systems are a promising combinatorial platform in IBD.Graphical
