Diversifying the skin cancer-fighting worthwhile frontiers: How relevant are the itraconazole/ascorbyl palmitate nanovectors? NANOMEDICINE : NANOTECHNOLOGY, BIOLOGY, AND MEDICINE 2022; 43:102561. [PMID: 35417773 DOI: 10.1016/j.nano.2022.102561] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 03/20/2022] [Accepted: 03/30/2022] [Indexed: 12/13/2022]
Abstract
Fighting malignant neoplasms via repurposing existing drugs could be a welcome move for prosperous cancer remediations. In the current work, nanovehiculation and optimization of the repositioned itraconazole (ITZ) utilizing ascorbyl palmitate (AP) aspasomes would be an auspicious approach. Further, the optimized aspasomes were incorporated in a cream and tracked for skin deposition. The in vivo efficacy of aspasomal cream on mice subcutaneous Ehrlich carcinoma model was also assessed. The optimized aspasomes revealed nano size (67.83 ± 6.16 nm), negative charge (-79.40 ± 2.23 mV), > 95% ITZ entrapment and high colloidal stability. AP yielded substantial antioxidant capacity and pushed the ITZ cytotoxicity forward against A431 cells (IC50 = 5.3±0.27 μg/mL). An appealing privilege was the aspasomal cream that corroborated spreadability, contemplated skin permeation and potentiated in vivo anticancer competence, reflected in 62.68% reduction in the tumor weight. Such synergistic tumor probes set the foundation for futuristic clinical translation and commercialization.

Abstract
The purpose of this study was to design, for the first time, a co-loaded liposomal formulation (CLL) for treatment of glaucoma including timolol maleate (TM) in the lipid bilayer and acetazolamide (Acz)-(2-hydroxy)propyl β-cyclodextrin (HPβCD) complexes (AczHP) solubilized in the aqueous core of liposomes. Formulations with TM (TM-L) and AczHP (AczHP-L), separately, were also prepared and characterized. A preliminary study comprising the Acz/HPβCD complexes and their interaction with cholesterol (a component of the lipid bilayer) was realized. Then, a screening study on formulation factors affecting the quality of the product was carried out following the design of the experiment methodology. In addition, in vitro release and permeation studies and in vivo lowering intraocular pressure (IOP) studies were performed. The results of the inclusion complexation behavior, characterization, and binding ability of Acz with HPβCD showed that HPβCD could enhance the water solubility of Acz despite the weak binding ability of the complex. Ch disturbed the stability and solubility parameters of Acz due to the fact of its competence by CD; thus, Chems (steroid derivative) was selected for further liposome formulation studies. The optimization of the lipid bilayer composition (DDAB, 0.0173 mmol and no double loading) and the extrusion as methods to reduce vesicle size were crucial for improving the physico-chemical properties and encapsulation efficiency of both drugs. In vitro release and permeation studies demonstrated that the CLL formulation showed improvement in in vitro drug release and permeation compared to the liposomal formulations with a single drug (TM-L and AczHP-L) and the standard solutions (TM-S and AczHP-S). CLL showed high efficacy in reducing and prolonging IOP, suggesting that the synergistic effect of TM and Acz on aqueous humor retention and the presence of this cyclodextrin and liposomes as permeation enhancers are responsible for the success of this strategy of co-loading for glaucoma therapy.

Development and optimization of hot-melt extruded moxifloxacin hydrochloride inserts, for ocular applications, using the design of experiments. Int J Pharm 2021; 603:120676.

Abstract
The current study sought to formulate sustained-release hot-melt extruded (HME) ocular inserts of moxifloxacin hydrochloride (MOX; MOX-HME) for the treatment of bacterial keratitis. The concentration of Eudragit™ FS-100 (FS) and propylene glycol (PG) used as polymer and plasticizer, respectively, in the inserts were optimized using the central composite design (CCD) to achieve sustained release. The inserts were characterized for weight, thickness, surface characteristics, pH, and in vitro release profile. The crystalline characteristics of MOX and surface morphology of the inserts were evaluated using differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). Furthermore, ex vivo permeation through rabbit cornea and stability of the optimized MOX-HME insert was investigated. The results demonstrate an inverse correlation between FS concentration and MOX release from the MOX-HME inserts, and a potential 24 h release. The optimized MOX-HME inserts were found to be stable at room temperature for four months, showing no significant change in drug content, pH and release profile. MOX converted into an amorphous form in the MOX-HME inserts and did not recrystallize during the study period. SEM analysis confirmed the smooth surface of the MOX-HME insert. The ex vivo studies revealed that the MOX-HME inserts provided a much prolonged transcorneal MOX flux as compared to the commercial ophthalmic solution and the immediate-release MOX-HME insert. The results indicate that MOX-HME inserts could potentially provide a once-a-day application, consequently reducing the dosing frequency and acting as an alternative delivery system in the management of bacterial infections.

Abstract
Offering a systematic and multivariate analysis of the analytical procedure, development and validation of HPLC methods using Quality by Design approach are in the limelight of current research trends. A new, experimental design-aided HPLC method for fampridine was developed and preliminarily validated according to current in-force international guidelines for linearity, accuracy, robustness and precision. The method offers a high throughput sample analysis, with an elution time of 2.9 minutes, and signal detection without excipient interference performed at 262 nm. The method proved to be linear between 1-15 µg mL-1 (R2= 0.9996). The mean recovery was found to be 98.7 ± 1.9 % in the tested range of 2.5-7.5 µg mL-1. Low RSD values (< 1 %) were obtained for both model, intra- and inter-day precision. The limit of detection and limit of quantification were 0.24 and 0.78 µg mL-1, resp. The method proved to be applicable for active substance assay in a pharmaceutical dosage form.

Abstract
Itraconazole is a triazole drug widely used in the treatment of fungal infections, and it is in clinical trials for treatment of several cancers. However, the drug suffers from poor solubility, while experiments have shown that itraconazole delivery in liposome nanocarriers improves both circulation half-life and tissue distribution. The drug release mechanism from the nanocarrier is still unknown, and it depends on several factors including membrane stability against defect formation. In this work, we used molecular dynamics simulations and potential of mean force (PMF) calculations to quantify the influence of itraconazole on pore formation over lipid membranes, and we compared the effect by itraconazole with a pore-stabilizing effect by the organic solvent dimethyl sulfoxide (DMSO). According to the PMFs, both itraconazole and DMSO greatly reduce the free energy of pore formation, by up to ∼20 kJ mol-1. However, whereas large concentrations of itraconazole of 8 mol % (relative to lipid) were required, only small concentrations of a few mole % DMSO (relative to water) were sufficient to stabilize pores. In addition, itraconazole and DMSO facilitate pore formation by different mechanisms. Whereas itraconazole predominantly aids the formation of a partial defect with a locally thinned membrane, DMSO mainly stabilizes a transmembrane water needle by shielding it from the hydrophobic core. Notably, the two distinct mechanisms act cooperatively upon adding both itraconazole and DMSO to the membrane, as revealed by an additional reduction of the pore free energy. Overall, our simulations reveal molecular mechanisms and free energies of membrane pore formation by small molecules. We suggest that the stabilization of a locally thinned membrane as well as the shielding of a transmembrane water needle from the hydrophobic membrane core may be a general mechanism by which amphiphilic molecules facilitate pore formation over lipid membranes at sufficient concentrations.

Abstract
Background: Intestinal nematode infections are usually treated with benzimidazole drugs, but the emergence of resistance to these drugs has led to an increasing demand of new anthelmintic strategies. A new microemulsion formulation (ME) consisting of an Artemisia absinthium extract with proven nematocidal efficacy was previously developed. The aim of our study is to implement a D-optimal mixture design methodology to increase the amount of a silica material (loaded with this ME) in a tablet formulation, considering its tensile strength and disintegration time. Methods: 16 experiments or combinations of the 6 tablet components (loaded silica, microcrystalline cellulose, polyvinylpyrrolidone, croscarmellose, Syloid® 244 FP and magnesium stearate) were assessed. Tensile strength and disintegration time models were developed, and an optimization process was carried out. Results: Tensile strength was improved by increasing the polyvinylpyrrolidone content, while croscarmellose decreased the disintegration time. The optimized powder mixture contains 49.7% w/w of the loaded silica material. A compression force of 12 kN was applied to the powder mixture to form tablets with a tensile strength of 2.0 MPa and a disintegration time of 3.8 min. Conclusions: Our results show that D-optimal mixture designs provide a promising approach to formulate liquid-loaded silica materials.

Abstract
![]()
Cholesterol
plays a crucial role in modulating the physicochemical
properties of biomembranes, both increasing mechanical strength and
decreasing permeability. Cholesterol is also a common component of
vesicle-based delivery systems, including liposome-based drug delivery
systems (LDSs). However, its effect on the partitioning of drug molecules
to lipid membranes is very poorly recognized. Herein, we performed
a combined experimental/computational study of the potential for the
use of the LDS formulation for the delivery of the antifungal drug
itraconazole (ITZ). We consider the addition of cholesterol to the
lipid membrane. Since ITZ is only weakly soluble in water, its bioavailability
is limited. Use of an LDS has thus been proposed. We studied lipid
membranes composed of cholesterol, 1-palmitoyl-2-oleoyl-sn-glycerol-3-phosphocholine (POPC), and ITZ using a combination of
computational molecular dynamics (MD) simulations of lipid bilayers
and Brewster angle microscopy (BAM) experiments of monolayers. Both
experimental and computational results show separation of cholesterol
and ITZ. Cholesterol has a strong preference to orient parallel to
the bilayer normal. However, ITZ, a long and relatively rigid molecule
with weakly hydrophilic groups along the backbone, predominantly locates
below the interface between the hydrocarbon chain region and the polar
region of the membrane, with its backbone oriented parallel to the
membrane surface; the orthogonal orientation in the membrane could
be the cause of the observed separation. In addition, fluorescence
measurements demonstrated that the affinity of ITZ for the lipid membrane
is decreased by the presence of cholesterol, which is thus probably
not a suitable formulation component of an LDS designed for ITZ delivery.

Abstract
Risedronate sodium (RS) is a potent inhibitor of bone resorption, having an extreme poor permeability and limited oral bioavailability (0.62%). RS should be orally administered under fasting conditions while keeping in an upright posture for at least 30 min to diminish common gastroesophageal injuries. To surmount such limitations, novel risedronate-chitosan (RS-CS) crosslinker-free nebulizable microspheres were developed adopting the quality by design (QbD) approach and risk assessment (RA) thinking. RS:CS ratio, surfactant (Pluronic® F127) concentration, homogenization duration, speed, and temperature were identified using Ishikawa diagrams as the highest formulation and process risk factors affecting the critical quality attributes (CQAs), average particle size (PS), and entrapment efficiency (EE%). The risk factors were screened using the Plackett-Burman design, and the levels of the most significant factors were optimized using a multilevel factorial design to explore the optimized system with the least PS, maximum EE%, and a prolonged drug release profile. The optimized system (B6) was developed at a RS:CS ratio of 1:7, a surfactant concentration of 2% (w/v), and a homogenization speed of 14,000 rpm. It revealed good correlation with QbD theoretical prediction, where positively charged (47.9 ± 3.39 mV) discrete, spherical microspheres (3.47 ± 0.16 μm) having a high EE% (94.58 ± 0.19%) and prolonged RS release over 12 h (Q12 h, 89.70 ± 0.64%) were achieved. In vivo lung deposition after intratracheal instillation of B6 confirmed the delivery of high RS percentage to rat lung tissues (87 ± 3.54%) and its persistence for 24 h. This investigation demonstrated the effectiveness of QbD philosophy in developing RS-CS crosslinker-free nebulizable microspheres.

Abstract
In couple of decennia, optimization tactics for drug delivery systems have been explored widely employing Design of Experiments (DoE) for desired outcomes to overcome drawbacks of "One Factor at a Time (OFAT)"conventional technique.. To pace with advances in computational approaches engaged in research domain, QbD-based tactic i.e. Formulation by Design (FbD) is under extensive investigation by budding scientists for better know-how of the product and process development for an unequivocal universal acceptation. Like other vesicular drug carriers, liposomes also demand robustness and reproducibility to scale up at industrial outset. Based on said outlook, this review focuses on the fundamentals and methodologies like Central Composite, Simplex Mixture, Box-Behnken, Factorial, Taguchi, Simplex Centroid, d-optimal, Placket Burman, and Orthogonal array with special reference to applications of FbD in the development of liposomes.

Abstract
Itraconazole (ITZ) is an FDA-approved antifungal agent that has recently been explored for novel biological properties. In particular, ITZ was identified as a potent inhibitor of the hedgehog (Hh) pathway, a cell signalling pathway that has been linked to a variety of cancers and accounts for ∼25% of paediatric medulloblastoma (MB) cases. To date, there is not a targeted therapeutic option for paediatric MB, resulting in long-term side effects such as hormone deficiency, organ damage and secondary cancers. A primary obstacle for developing targeted therapy for brain ailments is the presence of the blood-brain barrier (BBB), which protects the brain from potentially harmful substances. Due to its size and hydrophobicity, ITZ does not penetrate the BBB. Alternatively, liposomes are being increasingly used within the clinic to increase drug bioavailability, target specificity and BBB permeability. With this in mind, we have successfully developed ITZ-containing liposomes with an optimal size for BBB penetration (<100 nm) and encapsulation efficiency (∼95%) by utilizing a continuous manufacturing approach-turbulent coaxial jet in co-flow. Our preliminary in vitro data demonstrate that these liposomes inhibit the Hh pathway, albeit at a reduced level in comparison to free ITZ. (196/250 words).

Abstract
The purpose of this review is to discuss the challenges associated with the development of nanoparticle-based quality drug products in adhering to the principles of quality by design (QbD) and defining appropriate quality parameters towards successful product development. With the advent of nanotechnology into the pharmaceutical field, the novel field of nanomedicine was born. Due to their unique properties in terms of size, conformation and targeted delivery, nanomedicines are able to overcome many drawbacks of conventional medicine. As nano-sized formulations have made their way into more and more therapies, it has became clear that these very unique properties create hurdles for nanomedicines in successfully traversing the regulatory pathways and there is a need to develop nanomedicines in a more controlled and consistent fashion. The elements of a QbD methodology explained in this review enable the development of nano-based formulations in a way that maximizes the possibility of success. The identification of critical quality attributes (CQA) of the drug product and its intermediates are discussed in detail with a focus on nanomaterial-based formulations. In conclusion, QbD and the identification and specification of CQAs at its core are critical to the design, development and growth of nanomaterials in pharmaceuticals.

Abstract
The aim of this work was to use the quality-by-design (QbD) approach in the development of long-circulating liposomes co-loaded with curcumin (CUR) and doxorubicin (DOX) and to evaluate the cytotoxic potential of these liposomes in vitro using C26 murine colon carcinoma cell line. Based on a risk assessment, six parameters, namely the phospholipid, CUR and DOX concentrations, the phospholipid:cholesterol molar ratio, the temperature during the evaporation and hydration steps and the pH of the phosphate buffer, were identified as potential risk factors for the quality of the final product. The influence of these variables on the critical quality attributes of the co-loaded liposomal CUR and DOX was investigated: particle size, zeta potential, drug loading and entrapment efficiency. For this, a 26−2 factorial design was employed to establish a proper regression model and to generate the contour plots for the responses. The obtained data served to establish the design space for which different combinations of variables yielded liposomes with characteristics within predefined specifications. The validation of the model was carried out by preparing two liposomal formulations corresponding to the robust set point from within the design space and one outside the design space and calculating the percentage bias between the predicted and actual experimental results. The in vitro antiproliferative test showed that at higher CUR concentrations, the liposomes co-encapsulating CUR and DOX had a greater cytotoxic effect than DOX-loaded liposomes. Overall, this study showed that QbD is a useful instrument for controlling and optimizing the manufacturing process of liposomes co-loaded with CUR and DOX and that this nanoparticulate system possesses a great potential for use in colon cancer therapy.

Abstract
Itraconazole (ITZ) is an antifungal agent used clinically to treat mycotic infections. However, its therapeutic effects are limited by low solubility in aqueous media. Liposome-based delivery systems (LDS) have been proposed as a delivery mechanism for ITZ to alleviate this problem. Furthermore, PEGylation, the inclusion in the formulation of a protective "stealth sheath" of poly(ethylene glycol) around carrier particles, is widely used to increase circulation time in the bloodstream and hence efficacy. Together, these themes highlight the importance of mechanistic and structural understanding of ITZ incorporation into liposomes both with and without PEGylation because it can provide a potential foundation for the rational design of LDS-based systems for delivery of ITZ, using alternate protective polymers or formulations. Here we have combined atomistic simulations, cryo-TEM, Langmuir film balance, and fluorescence quenching experiments to explore how ITZ interacts with both pristine and PEGylated liposomes. We found that the drug can be incorporated into conventional and PEGylated liposomes for drug concentrations up to 15 mol % without phase separation. We observed that, in addition to its protective properties, PEGylation significantly increases the stability of liposomes that host ITZ. In a 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) bilayer without PEGylation, ITZ was found to reside inside the lipid bilayer between the glycerol and the double-bond regions of POPC, adopting a largely parallel orientation along the membrane surface. In a PEGylated liposome, ITZ partitions mainly to the PEG layer. The results provide a solid basis for further development of liposome-based delivery systems.

Abstract
Treatment of cryptococcal meningitis with antifungals such as itraconazol is difficult due their low concentration in the brain. Therefore, drug carriers with high payload are highly desired. But, generation of itraconazole loaded poly(butyl cyanoacrylate) nanoparticles with higher drug load, for instance more than 20% drug, is challenging. In present study we were able to generate novel highly loaded itraconazole poly(butyl cyanoacrylate) nanocapsules containing up to 99% (w/w) itraconazole and 1% polymer (w/w). Moreover, a controllable manufacturing procedure using a one-step emulsion solvent evaporation technique was established in order to discriminate between itraconazole loaded nanocapsules and nanospheres. Furthermore, it could be demonstrated that our novel nanocapsules can be decorated with targeting molecules such as apolipoprotein E. More precisely, apolipoprotein E was covalently bound to a maleimide linker, which was integrated within the surface of polymeric nanoparticle. This covalent binding of apolipoproteinE to the surface of a drug delivery system enables targeting of low density lipoprotein receptor (LDLR) expressed on endothelial brain capillary cell membranes, making our novel highly loaded itraconazole poly(butyl cyanoacrylate) nanocapsules a promising drug delivery system for treatment of cryptococcal meningitis.

Abstract
Alzheimer's disease is a neurological disorder that results in cognitive and behavioral impairment. Conventional treatment strategies, such as acetylcholinesterase inhibitor drugs, often fail due to their poor solubility, lower bioavailability, and ineffective ability to cross the blood-brain barrier. Nanotechnological treatment methods, which involve the design, characterization, production, and application of nanoscale drug delivery systems, have been employed to optimize therapeutics. These nanotechnologies include polymeric nanoparticles, solid lipid nanoparticles, nanostructured lipid carriers, microemulsion, nanoemulsion, and liquid crystals. Each of these are promising tools for the delivery of therapeutic devices to the brain via various routes of administration, particularly the intranasal route. The objective of this study is to present a systematic review of nanotechnology-based drug delivery systems for the treatment of Alzheimer's disease.

Abstract
To circumvent the low and erratic absorption of orally administrated cinnarizine (CN), intranasal lyophilized gels containing unsaturated fatty acid liposomes (ufasomes) and encapsulating CN were prepared from oleic acid using a simple assembling strategy. The effects of varying drug concentration and cholesterol percentage on ufasomes size, polydispersity index and entrapment efficiency were investigated using 3(1)4(1) full factorial design. The optimized ufasomes that contained 14% cholesterol relative to oleic acid displayed spherical morphology with average size of 788 nm and entrapment efficiency of 80.49%. To overcome the colloidal instability of CN-loaded ufasomes dispersions and their short residence time in the nasal cavity, the ufasomes were incorporated into mucoadhesive hydrogels that were lyophilized into unit dosage forms for accurate dosing. Scanning electron micrographs of the lyophilized gel revealed that the included ufasomes were intact, non-aggregating and maintained their spherical morphology. Rheological characterization of reconstituted ufasomal lyophilized gel ensured ease of application. Furthermore, the gel induced minor histopathological alterations in sheeps' nasal mucosa. Ex-vivo confocal laser imaging confirmed the ability of ufasomes to penetrate deep through nasal mucosa layers. The results highlighted in the current work confirm the feasibility of using CN-loaded ufasomal gels for intranasal drug delivery.

Abstract
In recent years, there has been an increased focus on developing novel drug delivery systems and targeted therapies through the use of nanotechnology and nanomaterials. Such focus is translating to an increasing number of investigational new drug (IND) applications, new drug applications (NDAs), and abbreviated new drug applications (ANDAs) for drug products containing nanomaterials to the United States Food and Drug Administration (FDA). Although subject to the same rigorous regulatory standards and regulatory pathways as any drug product, unique properties that arise from the small size, large surface area, and polydispersity of nanomaterials may lead to additional scientific considerations when following current FDA guidelines and practices for drug evaluation. This review article will discuss these scientific considerations based on the experience with FDA-approved drug products containing nanomaterials.

Abstract
The study aims to statistically develop a hydrogel of itraconazole loaded nonionic surfactant vesicles (NSVs) for circumventing the shortcomings and adverse effects of currently used therapies. Influential factors were screened using first-order Taguchi design, thereafter, optimization was performed via D-optimal design involving screened factors (surfactant type, content and molar ratio of cholesterol: surfactant). Response variables investigated were percent drug entrapment, vesicle size, drug skin retention and permeation in 6h. Suspensions of NSVs were gelled to improve topical applicability. Characterization of formulations was performed using vesicle shape, size, surface charge, texture analysis and rheology behavior. Ex vivo studies in rat skin depicted that optimized formulation augmented drug skin retention and permeation in 6h than conventional cream and oily solution of itraconazole. Standardized Tinea pedis model in Wistar rats exhibited in vivo antifungal efficacy of optimized formulation, observed in terms of physical manifestations, fungal-burden score and histopathological profiles. Also, a unique investigation involving studying local oxidative stress of infected paw skins as an indicator of fungal infection was performed. Rapid alleviation of infection in animals treated with optimized hydrogel was observed in comparison to commonly prescribed therapies. Therefore, the optimized NSVs may be a promising and efficient alternative to available antifungal therapies.
