[PMID: 38791175 PMCID: PMC11120910 DOI: 10.3390/ijms25105137] [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: 04/06/2024] [Revised: 05/02/2024] [Accepted: 05/04/2024] [Indexed: 05/26/2024] Open
Abstract
The modified release of active substances such as chlorzoxazone from matrix tablets, based on Kollidon®SR and chitosan, depends both on the drug solubility in the dissolution medium and on the matrix composition. The aim of this study is to obtain some new oral matrix tablet formulations, based on Kollidon®SR and chitosan, in order to optimize the low-dose oral bioavailability of chlorzoxazone, a non-steroidal anti-inflammatory drug of class II Biopharmaceutical Classification System. Nine types of chlorzoxazone matrix tablets were obtained using the direct compression method by varying the components ratio as 1:1, 1:2, and 1:3 chlorzoxazone/excipients, 20-40 w/w % Kollidon®SR, 3-7 w/w % chitosan while the auxiliary substances: Aerosil® 1 w/w %, magnesium stearate 0.5 w/w % and Avicel® up to 100 w/w % were kept in constant concentrations. Pharmaco-technical characterization of the tablets included the analysis of flowability and compressibility properties (flow time, friction coefficient, angle of repose, Hausner ratio, and Carr index), and pharmaco-chemical characteristics (such as mass and dose uniformity, thickness, diameter, mechanical strength, friability, softening degree, and in vitro release profiles). Based on the obtained results, only three matrix tablet formulations (F1b, F2b, and F3b, containing 30 w/w % KOL and 5 w/w % CHT, were selected and further tested. These formulations were studied in detail by Fourier-transform infrared spectrometry, X-ray diffraction, thermogravimetry, and differential scanning calorimetry. The three formulations were comparatively studied regarding the release kinetics of active substances using in vitro release testing. The results were analyzed by fitting into four representative mathematical models for the modified-release oral formulations. In vitro kinetic study revealed a complex mechanism of release occurring in two steps of drug release, the first step (0-2 h) and the second (2-36 h). Two factors were calculated to assess the release profile of chlorzoxazone: f1-the similarity factor, and f2-the factor difference. The results have shown that both Kollidon®SR and chitosan may be used as matrix-forming agents when combined with chlorzoxazone. The three formulations showed optima pharmaco-technical properties and in vitro kinetic behavior; therefore, they have tremendous potential to be used in oral pharmaceutical products for the controlled delivery of chlorzoxazone. In vitro dissolution tests revealed a faster drug release for the F2b sample.

Abstract
Taking curcumin as the starting point, β-cyclodextrin was introduced on both sides, and lipid-soluble curcumin was coated by acrylic resin using oil-in-water strategy. Four different types of curcumin fluorescent complexes EPO-Curcumin (EPO-Cur), L100-55-Curcumin (L100-55-Cur), EPO -Curcumin-β-cyclodextrin (EPO-Cur-β-cd) and L100-55-Curcumin-β-cyclodextrin (L100-55-Cur-β-cd) were prepared to solve their own solubility and biocompatibility issues. The prepared curcumin fluorescent complexes were characterized and tested by spectroscopy. The characteristic peaks of 3446 cm−1 (hydroxyl group), 1735cm−1(carbonyl group) and 1455 cm−1 (aromatic group) were determined in the infrared spectrum. In the fluorescence emission spectrum, it was found that the emission intensity of different curcumin fluorescent complexes in polar solvents reached hundreds of times. Through the transmission electron microscopy shows that acrylic resin tightly coats curcumin into rods or clusters. In order to observe their compatibility with tumor cells more directly, live cell fluorescence imaging was carried out, and it was found that all four kinds of curcumin fluorescence complexes had good biocompatibility. In particular, the effect of EPO-Cur-β-cd and L100-55-Cur-β-cd is better than that of EPO-Cur and L100-55-Cur.

Abstract
In this current article matrix formulations for oral drug delivery are reviewed. Conventional dosage forms and novel applications such as 3D printed matrices and aerogel matrices are discussed. Beside characterization, excipients and matrix forming agents are also enlisted and classified. The incorporated drug could exist in crystalline or in amorphous forms, which makes drug dissolution easily tunable. Main drug release mechanisms are detailed and reviewed to support rational design in pharmaceutical technology and manufacturing considering the fact that R&D members of the industry are forced to obtain knowledge about excipients and methods pros and cons. As innovative and promising research fields of drug delivery, 3D printed products and highly porous, low density aerogels with high specific surface area are spreading, currently limitlessly. These compositions can also be considered as matrix formulations.

Abstract
Cooperation between researchers in the areas of medical, pharmaceutical and materials science has facilitated the development of pharmaceutical dosage forms that elicit therapeutic effects and protective action with a single product. In addition to optimizing pharmacologic action, such dosage forms provide greater patient comfort and increase success and treatment compliance. In the present work, we prepared semipermeable bioactive electrospun fibers for use as wound dressings containing silver sulfadiazine complexed with β-cyclodextrin in a poly(Ɛ-caprolactone) nanofiber matrix aiming to reduce the direct contact between silver and skin and to modulate the drug release. Wound dressings were prepared by electrospinning, and were subjected to ATR-FT-IR and TG/DTG assays to evaluate drug stability. The hydrophilicity of the fibrous nanostructure in water and PBS buffer was studied by goniometry. Electrospun fibers permeability and swelling capacity were assessed, and a dissolution test was performed. In vitro biological tests were realized to investigate the biological compatibility and antimicrobial activity. We obtained flexible matrices that were each approximately 1.0 g in weight. The electrospun fibers were shown to be semipermeable, with water vapor transmission and swelling indexes compatible with the proposed objective. The hydrophilicity was moderate. Matrices containing pure drug modulated drug release adequately during 24 h but presented a high hemolytic index. Complexation promoted a decrease in the hemolytic index and in the drug release but did not negatively impact antimicrobial activity. The drug was released predominantly by diffusion. These results indicate that electrospun PCL matrices containing β-cyclodextrin/silver sulfadiazine inclusion complexes are a promising pharmaceutical dosage form for wound healing.

Abstract
Curcumin is the main bioactive component of Curcuma longa L. and has recently aroused growing interest from the scientific community. Unfortunately, the medicinal properties attributed to curcuminoids are impaired by their low oral bioavailability or low solubility in aqueous solutions. Many strategies have been studied to improve curcumin solubility; however, the preparation of granules using hydrophilic materials has never been attempted. The aim of this work was to develop curcumin granules by fluidized bed hot-melt granulation using the hydrophilic carrier Gelucire® 50:13. A two-level factorial design was used to verify the influence of Gelucire® 50:13 and lactose contents found in the granules on their size, morphology, bulk and tapped densities, flow, moisture content, and water activity. The granules obtained were also evaluated by differential scanning calorimetry, thermogravimetric analysis, X-ray powder diffraction, and infrared spectrometry. The curcumin solubility and dissolution rates in water were determined by liquid chromatography. The best formulation provides an increase of curcumin solubility of 4642-fold and 3.8-fold compared to the physical mixture. The dissolution tests showed a maximum drug release from granules after 45 min of 70% at pH 1.2 and 80% at pH 5.8 and 7.4, while for non-granulated curcumin, the release was below 20% in all pH. The solid-state characterization and solubility measurement showed good stability of granules over 9 months. The results attest that the fluidized bed hot-melt granulation with hydrophilic binders is an attractive and promising alternative to obtain solid forms of curcumin with enhanced bioavailability.

Abstract
This pre-formulation study assays the capacity of the polyesteramide PADAS, poly (L-alanine-dodecanediol-L-alanine-sebacic), as an insoluble tablet excipient matrix for prolonged drug release. The flow properties of PADAS were suitable for tableting, and the compressibility of tablets containing exclusively PADAS was evaluated by ESEM observation of the microstructure. The tablets were resistant to crushing and non-friable and they did not undergo disintegration (typical features of an inert matrix). Tablets containing 33.33% sodium diclofenac (DF), ketoprofen (K) or dexketoprofen trometamol (DK-T) as a model drug, in addition with 66.67% of polymer, were formulated, and the absence of interactions between the components was confirmed by differential scanning calorimetry. Dissolution tests showed that PADAS retained DF and K and prolonged drug release, following a Higuchi kinetic. The tablets containing DK-T did not retain the drug sufficiently for prolonged release to be established. Tablets containing DK-T and 66.67, 83.33 or 91.67% PADAS, compressed at 44.48 or 88.96 kN, were elaborated to determine the influence of the polymer amount and of the compression force on DK-T release. Both parameters significantly delayed drug release, except when the proportion of polymer was 91.67%.

Abstract
Many commonly used tablet fillers are not suitable for direct compaction process due to insufficient properties, mainly of flowability and compactability. This work therefore aimed to use co-spray drying with HPMC as a platform to improve direct compaction properties of various tablet fillers. Starch, calcium hydrogen phosphate dihydrate (DCPD), and mannitol were chosen as a representative of three types of commonly used fillers (i.e. organic macromolecules, water-insoluble inorganic salts, and water-soluble small molecular carbohydrates), respectively. The five-level central composite design-response surface methodology was used (i) to investigate the effects of HPMC level and solid content of the feed on various powder, tableting, and tablet properties of composite excipients, and (ii) to optimize the composition. The results showed that the impacts of the two factors on various properties of composite excipients showed great similarity, despite of significantly different primary properties of the parent fillers, and the HPMC level was the main contributor to the majority of the impacts. An increase in HPMC level significantly improved tablet tensile strength and various tableting parameters. For all the three fillers, their optimized composite excipients provided by the established models showed excellent performances as predicted. The platform suggested is confirmed to be effective and promising.

Abstract
Direct compaction (DC) is the preferred choice for tablet manufacturing; however, only less than 20% of active pharmaceutical ingredients could be compacted via DC as its high requirement for functional properties of materials. Materials with improper functionalities could lead to serious troubles during DC manufacturing, such as content non-uniformity, sticking, and capping, all of which profoundly affect the properties of final products and, thus, severely restrict the practical application of DC. With undoubted importance, these seem to be unexpectedly ignored by reviewers but not researchers in terms of many original research articles published recently. Therefore, as an informative supplement and update, this review mainly focused on trouble-shooting and application situation of DC, together with several newly reported materials.

Abstract
The objective of this study was to investigate the lubrication properties of hexagonal boron nitride (HBN) on a (1:1) binary mixture of Avicel DG and Starch 1500 after using the dry granulation-slugging method and compare it with conventional lubricants, such as magnesium stearate (MGST), glyceryl behenate (COMP) and stearic acid (STAC). MGST is one of the most commonly used lubricants in the pharmaceutical industry. However, it has several adverse effects on tablet properties. In our current study, we employed various methods to eradicate the work hardening phenomenon in dry granulation, and used HBN as a new lubricant to overcome the adverse effects of other lubricants on tablet properties. HBN was found to be as effective as MGST and did not show any significant adverse effects on the crushing strength or work hardening. From the scanning electron microscope (SEM) images, it was concluded that HBN distributed better than MGST. As well as showing better distribution, HBN's effect on disintegration was the least pronounced. Semi-quantitative weight percent distribution of B and N elements in the tablets was obtained using EDS (energy dispersive spectroscopy). Based on atomic force microscope (AFM) surface roughness images, formulations prepared with 1% HBN showed better plastic character than those prepared with MGST.
