Abstract
Atorvastatin (ATV) is a first-line drug for the treatment of hyperlipidemia. This drug presents biopharmaceutical problems, partly due to its low solubility and dissolution rate. In this work, nanocrystals of ATV stabilized with Tween 80® were designed by wet milling. A full factorial design was applied to optimize the process. Additionally, a cryoprotectant agent (maltodextrin, MTX) was identified, which allowed maintaining the properties of the nanocrystals after lyophilization. The storage stability of the nanocrystals was demonstrated for six months in different conditions. The obtained nanocrystal powder was characterized using SEM, EDXS, TEM, DSC, TGA, FT-IR, and XRD, showing the presence of irregular crystals with semi-amorphous characteristics, likely due to the particle collision process. Based on the reduction in particle size and the decrease in drug crystallinity, a significant increase in water and phosphate buffer (pH 6.8) solubility by 4 and 6 times, respectively, was observed. On the other hand, a noticeable increase in the dissolution rate was observed, with 90 % of the drug dissolved within 60 min of study, compared to 30 % of the drug dissolved within 12 h in the case of the untreated drug or the physical mixture of components. Based on these results, it can be concluded that the nano-milling of Atorvastatin stabilized with Tween 80® is a promising strategy for developing new formulations with improved biopharmaceutical properties of this widely used drug.

Curcumin nanocrystals-in-nanofibres as a promising platform for the management of periodontal disease. Int J Pharm 2023; 648:123585. [PMID: 37952560 DOI: 10.1016/j.ijpharm.2023.123585] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 11/06/2023] [Accepted: 11/07/2023] [Indexed: 11/14/2023]
Abstract
It is estimated that nearly a half of the world's population over 30 years old suffer from some kind of periodontal disease (PD). Although preventable, PD can pose a significant health burden to patients, causing from pain and discomfort to disfigurement and death. The management of PD often requires surgical procedures accompanied of systemic antibiotic and anti-inflammatory treatments. Curcumin (CUR), a potent anti-inflammatory and antimicrobial active, has shown great promise in the management of PD; however, its effects are often limited by its low bioavailability. In this work, we report the development of electrospun nanofibres (NFs) loaded with CUR nanocrystals (NCs) for the management of PD. NCs of 100 nm were obtained by media milling and loaded into dissolving polyvinyl alcohol NFs using electrospinning. The resultant NCs-in-NFs dissolved in water spontaneously, releasing NCs with a particle size of ∼120 nm. The physiochemical characterisation of the systems indicated the absence of chemical interactions between drug and polymer, and nanofibres with an amorphous nature. In vitro release profiles demonstrated that the NCs had a significantly higher dissolution rate (∼100 % at day 40) than the control group (approximately 6 % at day 40), which consisted of NFs containing a physical mixture of the drug and stabiliser. Finally, mucosal deposition studies demonstrated a 10-fold higher capacity of the novel NCs-in-NFs system to deposit CUR ex vivo using excised neonatal porcine mucosal tissue, when compared to the control group.

Abstract
Triamcinolone acetonide (TA) is a powerful anti-inflammatory drug used in the treatment of inflammatory ocular disorders; however, its poor aqueous solubility and ocular anatomical barriers hinder optimal treatment. The aim of this work was to obtain triamcinolone acetonide nanocrystals (TA-NC) to improve ocular corticosteroid therapy. Self-dispersible TA-NC were prepared by the bead milling technique followed by spray-drying, exhaustively characterized and then evaluated in vivo in an ocular model of endotoxin-induced uveitis (EIU). Self-dispersible TA-NC presented an average particle size of 257 ± 30 nm, a narrow size distribution and a zeta potential of -25 ± 3 mV, which remained unchanged for 120 days under storage conditions at 25 °C. In addition, SEM studies of the TA-NC showed uniform and spherical morphology, and FTIR and XRDP analyses indicated no apparent chemical and crystallinity changes. The subconjunctival administration of TA-NC in albino male white rabbits showed no clinical signs of ocular damage. In vivo studies proved that treatment with self-dispersible TA-NC alleviated the inflammatory response in the anterior chamber and iris in EUI rabbit eyes. Dispersible TA-NC are a promising approach to obtaining a novel nanometric TA formulation for ocular disorders.

Abstract
This is the first report on the inclusion of nanocrystals (NCs) within 3D-printed oral solid dosage forms -3D-printed tablets or printlets- produced by the Melting Solidification Printing Process (MESO-PP) 3D printing technique. This method allowed the incorporation of albendazole (ABZ) nanocrystals in a concentration of up to 50% w/w, something not achieved in conventional tablets. An ink of PEG 1500/propylenegycol was used as a carrier and no physicochemical interactions or crystallinity modifications were observed due to the inclusion of ABZ-NCs into the ink, as demonstrated by TGA, DSC, XRD and FT-IR. In particular, the relative crystallinity of the ink loaded with NCs was 97.8% similar to the physical mixture of the components. Moreover, the presence of NCs was observed in the surface and matrix of the printlets by SEM. In addition, the printlet NCs demonstrated to be more effective than NCs included in hard gelatin capsules in improving drug dissolution in HCl 0.1 N. The particle size, crystallinity and chemical stability of the nanocrystals was maintained before and after 180 days of storage. Thus, these findings exhibit relevant pharmaceutical potential for developing stable, fast-release, oral, solid dosage forms of poorly soluble drugs combining 3D printing and nanocrystals. Additionally, this technique could be applied for printing objects using different types of nanocrystals embedded in low melting temperature polymers.

Abstract
Zotepine is an atypical antipsychotic drug used in the treatment of schizophrenia. However, its poor dissolution properties limit its therapeutic efficacy. In this investigation, a series of nanosuspension-containing zotepine were prepared employing media milling method with an aim to improve its dissolution properties and oral bioavailability. Briefly, Box-Behnken design was applied to investigate the influence of various independent variables such as X1- amount of stabilizer, X2- amount of milling agent, and X3- milling time on the performance of the formulation. Dissolution studies revealed enhancement of dissolution rate as compared to pure drug. Solid state characterization (DSC, PXRD, and SEM) studies demonstrated no polymorphic changes in drug after lyophilization of media-milled nanosuspension. In vivo pharmacokinetic studies of lyophilized nanosuspension was carried out in rat and the results exhibited significant improvement in Cmax and AUC0-t, about 450.0 and 287.45%, respectively, suggesting amelioration in oral bioavailability by 2.87-fold higher as compared to pure drug. Accelerated stability studies of the optimized lyophilized formulation at 40°C and 75% RH suggested stability of the nanocrystals for at least a 6-month period. The obtained nanocrystals successfully showed dissolution enhancement and improved oral bioavailability of poorly water-soluble drug, zotepine.

Abstract
Benzimidazole methylcarbamate anthelmintics, including fenbendazole (FBZ), have only limited water solubility and small differences in drug solubility may have a major influence on their absorption, pharmacokinetic behavior and anthelmintic efficacy. To improve FBZ water solubility and dissolution rate, novel self-dispersible nanocrystals (SDNCs) of FBZ were recently described. In this work, the pharmacokinetic behavior of the SDNCs of FBZ and Poloxamer 188 was compared against a physical mixture (PM) of its components. The experiment was conducted following a crossover design with two different experimental phases. In phase I, sheep were treated with the SDNC (n = 3) or the PM (n = 3) formulations by the intraruminal route at the same dose rate (5 mg/kg). The treatment groups were reversed after a 7-days washout period. A non-compartmental analysis of the concentration in plasma versus time results showed that the calculated Cmax and AUC0-T were significantly higher (p < 0.05) for FBZ and its metabolites after the SDNC treatment compared to the PM (for FBZ: Cmax 0.346 μg/mL and AUC0-T 10.1 μg.h/mL after the SDNC vs Cmax 0.157 μg/mL and AUC0-T 5.1 μg.h/mL after the PM treatment). Additionally, population pharmacokinetic parameters of FBZ were estimated for the first time in sheep. In conclusion, the formulation of FBZ as SDNCs is a promising approach to improve FBZ dissolution reaching a higher drug plasma exposure in ruminants.

Abstract
Low water solubility and thus low bioavailability limit the clinical application of fenbendazole (FBZ) as a potential anticancer drug. Solubilizing agents, such as Mobil Composition of Matter Number 41 (MCM) as a drug carrier, can improve the water solubility of drugs. In this study, PEGylated MCM (PEG-MCM) nanoparticles (NPs) were synthesized and loaded with FBZ (PEG-MCM-FBZ) to improve its solubility and, as a result, its cytotoxicity effect against human prostate cancer PC-3 cells. The loading efficiency of FBZ onto PEG-MCM NPs was 17.2%. The size and zeta potential of PEG-MCM-FBZ NPs were 366.3 ± 6.9 nm and 24.7 ± 0.4 mV, respectively. They had a spherical shape and released the drug in a controlled manner at pH 1.2 and pH 6.2. PEG-MCM-FBZ were found to inhibit the migration of PC-3 cells, increase the cytotoxicity effects of FBZ against PC-3 cells by 3.8-fold, and were more potent by 1.4-fold, when compared to the non-PEGylated NPs. In addition, PEG-MCM-FBZ promoted the production of reactive oxygen species by 1.3- and 1.2-fold, respectively, when compared to FBZ and MCM-FBZ. Overall, the results demonstrate that PEG-MCM-FBZ NPs enhanced FBZ delivery to PC-3 cells; therefore, they have the potential to treat prostate cancer after a comprehensive in vivo study.

Abstract
Cystic echinococcosis (CE) is a zoonosis caused by Echinococcus spp., affecting both humans and animals' lives. Current treatment of CE by oral administration of albendazole (ABZ) is hampered by several limitations. The poor aqueous solubility and the rapid metabolism of ABZ in the liver are the main issues, leading to lack of efficacy of the treatment. In the present study, we developed a nanocrystalline (NC) formulation of ABZ to be delivered intradermally using dissolving microneedles (DMNs). The NC formulation was developed using milling in an ultrasmall-scale device. Following several screenings, Pluronic F127 was selected as a suitable stabilizer, producing NCs with around 400 nm in size with narrow particle distribution. The crystallinity of ABZ was maintained as observed by DSC and XRD analysis. The NC approach was able to improve the dissolution percentage of ABZ by approximately three-fold. Furthermore, the incorporation of NCs into DMNs using the combination of poly(vinylpyrrolidone) and poly(vinyl alcohol) formed sharp needles with sufficient mechanical strength and insertion properties. Dermatokinetic studies revealed that >25% of ABZ was localized in the dermis of excised neonatal porcine skin up to 48 h after DMN administration. In in vivo pharmacokinetic studies, the AUC and relative bioavailability values of ABZ delivered by NC-loaded DMNs were found to be significantly higher than those obtained after oral administration of coarse suspension of ABZ or ABZ-NCs, as well as DMNs delivering coarse ABZ as indicated by the relative bioavailability values of >100%. Therefore, the combination approach developed in this study could maintain the systemic circulation of ABZ, which could be possibly caused by avoiding the first-pass metabolism in the liver. This could be beneficial to improve the efficacy of ABZ in CE treatment.

Optimization and Pharmacokinetic Evaluation of Synergistic Fenbendazole and Rapamycin Co-Encapsulated in Methoxy Poly(Ethylene Glycol)- b-Poly(Caprolactone) Polymeric Micelles. Int J Nanomedicine 2021; 16:4873-4889. [PMID: 34295160 PMCID: PMC8291852 DOI: 10.2147/ijn.s315782] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 07/02/2021] [Indexed: 12/18/2022] Open
Abstract
Purpose We aimed to develop a nanocarrier formulation incorporating fenbendazole (FEN) and rapamycin (RAPA) with strong efficacy against A549 cancer cells. As FEN and RAPA are poorly soluble in water, it is difficult to apply them clinically in vivo. Therefore, we attempted to resolve this problem by encapsulating these drugs in polymeric micelles. Methods We evaluated drug synergy using the combination index (CI) values of various molar ratios of FEN and RAPA. We formed and tested micelles composed of different polymers. Moreover, we conducted cytotoxicity, stability, release, pharmacokinetic, and biodistribution studies to investigate the antitumor effects of FEN/RAPA-loaded mPEG-b-PCL micelles. Results We selected mPEG-b-PCL-containing FEN and RAPA at a molar ratio of 1:2 because these particles were consistent in size and had high encapsulation efficiency (EE, %) and drug loading (DL, %) capacity. The in vitro cytotoxicity was assessed for various FEN, RAPA, and combined FEN/RAPA formulations. After long-term exposures, both the solutions and the micelles had similar efficacy against A549 cancer cells. The in vivo pharmacokinetic study revealed that FEN/RAPA-loaded mPEG-b-PCL micelles had a relatively higher area under the plasma concentration–time curve from 0 to 2 h (AUC0–2 h) and 0 to 8 h (AUC0–8 h) and plasma concentration at time zero (Co) than that of the FEN/RAPA solution. The in vivo biodistribution assay revealed that the IV injection of FEN/RAPA-loaded mPEG-b-PCL micelles resulted in lower pulmonary FEN concentration than the IV injection of the FEN/RAPA solution. Conclusion When FEN and RAPA had a 1:2 molar ratio, they showed synergism. Additionally, using data from in vitro cytotoxicity, synergism between a 1:2 molar ratio of FEN and RAPA was observed in the micelle formulation. The FEN/RAPA-loaded mPEG-b-PCL micelle had enhanced bioavailability than the FEN/RAPA solution.

Abstract
Benzimidazole (BMZ) family of anti-worm drugs has been now repurposed as anti-cancer drugs. However, offering a general reformulation method for these drugs is essential due to their hydrophobicity and low aqueous solubility. In this work, we developed a general approach to load typical BMZ drugs as tiny nanocrystals within lipid-coated calcium phosphate (LCP) nanoparticles. BMZ drug-loaded LCP nanoparticles increased their solubility in PBS by 100–200% and significantly enhanced the anti-cancer efficacy in the treatment of B16F0 melanoma cells. These drug-LCP nanoparticles induced much more cancer cell apoptosis, generated much more reactive oxygen species (ROS) and inhibited Bcl-2 expression of cancer cells. Moreover, BMZ drug-loaded LCP nanoparticles caused morphological change and extension disruption of cancer cells, and significantly reduced migration activity, representing high possibility for inhibition of tumor dissemination and metastasis. Very advantageously, BMZ drug-loaded LCP nanoparticles did not show any obvious toxicity, Bcl-2 inhibition and morphological changes in HEK293T healthy cells. In conclusion, BMZ drug-incorporated LCP nanoformulations may be a valuable nanomedicine that is able to inhibit primary tumors and prevent tumor dissemination with minimum side effects on healthy cells and tissues.

Abstract
Despite the existence of a variety of contraceptive products for women, as well as decades of research into the prevention and treatment of human immunodeficiency virus (HIV), there is still a globally unmet need for easily accessible, acceptable, and affordable products to protect women's sexual and reproductive health. Microarray patches (MAPs) are a novel platform being developed for the delivery of hormonal contraception and antiretroviral drugs. MAPs provide enhanced drug delivery to the systemic circulation via the transdermal route when compared to transdermal patches, oral and injectable formulations. These minimally invasive patches can be self-administered by the user, reducing the burden on health care personnel. Since MAPs represent needle-free drug delivery, no sharps waste is generated after application, thereby eliminating possible MAP reuse and risk of needle-stick injuries. This review discusses the administration of contraceptive and antiretroviral drugs using MAPs, their acceptability by end-users, and the future perspective of the field.
