Abstract
Electrospraying for Vitamin C (VC) encapsulation in Chitosan (Cs) nanoparticles was investigated and particle size, zeta potential, loading capacity (LC%) and encapsulation efficiency (EE%) were examined. Cs concentration (1-2% w/v) and voltage (21-25 kV) were varied with VC (0.25-0.75 w/w Cs). Twenty experiments in a face-centered CCD-RSM design were evaluated. ANOVA suggested voltage and Cs concentration as significant factors for particle size and VC content affected zeta, LC and EE%. RSM proposed optimum processing parameter at 2% Cs, 0.746 VC: Cs mass ratio and 21 kV voltage with 251.1 ± 59.03 nm particle size, 36.6% LC and an EE of 85.42%. Encapsulated particles were subjected to release behaviour, antioxidant property and analyzed through FTIR, DSC and XRD. Encapsulated VC had better antibacterial properties than Cs nanoparticles, and comparable VC retention in apple juice showed its effectiveness. Overall, nanoencapsulation of VC using electrospraying was successfully developed to be used in numerous food processing applications.

Gaikwad SS, Kshirsagar SJ. Application of Tablet in Tablet technique to design and characterize immediate and modified release tablets of Timolol maleate. Heliyon 2024; 10:e25820. [PMID: 38356537 PMCID: PMC10865078 DOI: 10.1016/j.heliyon.2024.e25820] [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: 05/18/2023] [Revised: 02/01/2024] [Accepted: 02/02/2024] [Indexed: 02/16/2024] Open
Abstract
Hypertension is one of the major causes of mortality in the world. The non-selective -β-blocker which includes Timolol maleate (TM) is usually used in hypertension, at a given dose of 10-40 mg. The present research aims to design a tablet-in-tablet (TIT) formulation as a single-unit dosage form to achieve modified and rapid drug release. Wet granulation was used to create the inner core modified release tablet utilising the release modifying agent's Sodium alginate (SA) and Hydroxypropyl methylcellulose (HPMC K4M). The impact of independent factors, SA and HPMC K4M, in different percentages of w/w, which affect the in vitro drug release and swelling index, was investigated using a 32 complete factorial design. The TM outer instant-release shell, which was made using croscarmellose sodium and Microcrystalline cellulose (MCC) in three distinct sizes, was press-coated onto the optimised inner core tablet. The core and outer shell tablets are within acceptable ranges for several physicochemical properties. No indication of interactions between drugs, polymers, and excipients was found in the Fourier transform infrared (FTIR) and Differential scanning calorimetry (DSC) investigations. The inner core tablet's formulation F6 achieves a 96.38% in vitro drug release at 24 h and a swelling index of 52.7%. The TIT-2 was, however, considered as the final tablet-in-tablet formulation because contains fewer excipients and shorter disintegration time than TIT-3.

Abstract
Cancer is a significant global public health concern, ranking as the leading cause of mortality worldwide. This study thoroughly explores boron-doped carbon dots (B-CDs) through a simple/rapid microwave-assisted approach and their versatile applications in cancer therapy. The result was highly uniform particles with an average diameter of approximately 4 nm. B-CDs exhibited notable properties, including strong fluorescence with a quantum yield of 33%. Colloid stability tests revealed their robustness within a pH range of 6-12, NaCl concentrations up to 0.5 M, and temperatures ranging from 30 to 60 °C. The study also delved into the kinetics of naproxen release from B-CDs as a drug delivery system. The loading efficacy of naproxen exceeded 55.56%. Under varying pH conditions, the release of naproxen from B-CDs conformed to the Peppas-Sahlin model, demonstrating the potential of Naproxen-loaded CDs for cancer drug delivery. In vitro cytotoxicity assessments, conducted using the CCK-8 Assay and flow cytometry, consistently indicated low toxicity with average cell viability exceeding 80%. An in vivo toxicity test on female mice administered 20 mg/kg of B-CDs for 31 days revealed reversible histological changes in the liver and kidneys, while the pancreas remained unaffected. Importantly, B-CDs did not impact the mice's physical behavior, body weight, or survival. In vivo experiments targeting benzo(a)pyrene-induced fibrosarcoma demonstrated the efficacy of B-CDs as naproxen carriers in the treatment of cancer. This in vivo study provides a thorough comprehension of B-CDs synthesis and toxicity and their potential applications in cancer therapy and drug delivery systems.

Abstract
Berberine (BER) is an alkaloid obtained from berberis plant having broad biological activities including anticancer. BER-encapsulated alginate (ALG)/chitosan (CHS) nanoparticles (BER-ALG/CHS-NPs) were developed for long-acting improved treatment in breast cancer. The surface of the NPs was activated by a conjugation reaction, and thereafter, the BER-ALG/CHS-NP surface was grafted with folic acid (BER-ALG/CHS-NPs-F) for specific targeting in breast cancer. BER-ALG/CHS-NPs-F was optimized by applying the Box-Behnken design using Expert design software. Moreover, formulations are extensively evaluated in vitro for biopharmaceutical performances and tested for cell viability, cellular uptake, and antioxidant activity. The comparative pharmacokinetic study of formulation and free BER was carried out in animals for estimation of bioavailability. The particle size recorded for the diluted sample using a Malvern Zetasizer was 240 ± 5.6 nm. The ζ-potential and the predicted % entrapment efficiency versus (vs) observed were +18 mV and 83.25 ± 2.3% vs 85 ± 3.5%. The high % drug release from the NPs was recorded. The analytical studies executed using infrared spectroscopy, differential scanning calorimetry, and X-ray diffraction expressed safe combinations of the components in the formulation and physical state of the drug revealed to be amorphous in the formulation. Cytotoxicity testing demonstrated that the formulation effectively lowered the cell viability and IC50 of the tested cell line in comparison to a raw drug. The cellular uptake of BER-ALG/CHS-NPs-F was 5.5-fold higher than that of BER-suspension. The antioxidant capacities of BER-ALG/CHS-NPs-F vs BER-suspension by the DPPH assay were measured to be 62.3 ± 2.5% vs 30 ± 6%, indicating good radical scavenging power of folate-conjugated NPs. The developed formulation showed a 4.4-fold improved oral bioavailability compared to BER-suspension. The hemolytic assay intimated <2% destruction of erythrocytes by the developed formulation. The observed experimental characterization results such as cytotoxicity, cellular uptake, antioxidant activity, and improved absorption suggested the effectiveness of BER-ALG/CHS-NPs-F toward breast cancer.

Abstract
Targeted delivery of drug molecules to diseased sites is a great challenge in pharmaceutical and biomedical sciences. Fabrication of drug delivery systems (DDS) to target and/or diagnose sick cells is an effective means to achieve good therapeutic results along with a minimal toxicological impact on healthy cells. Biopolymers are becoming an important class of materials owing to their biodegradability, good compatibility, non-toxicity, non-immunogenicity, and long blood circulation time and high drug loading ratio for both macros as well as micro-sized drug molecules. This review summarizes the recent trends in biopolymer-based DDS, forecasting their broad future clinical applications. Cellulose chitosan, starch, silk fibroins, collagen, albumin, gelatin, alginate, agar, proteins and peptides have shown potential applications in DDS. A range of synthetic techniques have been reported to design the DDS and are discussed in the current study which is being successfully employed in ocular, dental, transdermal and intranasal delivery systems. Different formulations of DDS are also overviewed in this review article along with synthesis techniques employed for designing the DDS. The possibility of these biopolymer applications points to a new route for creating unique DDS with enhanced therapeutic qualities for scaling up creative formulations up to the clinical level.

Abstract
The oral route has long been recognized as the most preferred route for drug delivery as it offers high patient compliance and requires minimal expertise. Unlike small molecule drugs, the harsh environment of the gastrointestinal tract and low permeability across the intestinal epithelium make oral delivery extremely ineffective for macromolecules. Accordingly, delivery systems that are rationally constructed with suitable materials to overcome barriers to oral delivery are exceptionally promising. Among the most ideal materials are polysaccharides. Depending on the interaction between polysaccharides and proteins, the thermodynamic loading and release of proteins in the aqueous phase can be realized. Specific polysaccharides (dextran, chitosan, alginate, cellulose, etc.) endow systems with functional properties, including muco-adhesiveness, pH-responsiveness, and prevention of enzymatic degradation. Furthermore, multiple groups in polysaccharides can be modified, which gives them a variety of properties and enables them to suit specific needs. This review provides an overview of different types of polysaccharide-based nanocarriers based on different kinds of interaction forces and the influencing factors in the construction of polysaccharide-based nanocarriers. Strategies of polysaccharide-based nanocarriers to improve the bioavailability of orally administered proteins/peptides were described. Additionally, current restrictions and future trends of polysaccharide-based nanocarriers for oral delivery of proteins/peptides were also covered.

Abstract
In this work, the swelling and disintegration of drug-free sodium alginate (SA) compacts and the release of metformin HCl from SA matrix tablets were investigated in acidic media of different ethanol concentrations (0, 10, 20, and 40 % v/v), pH (1.2 and 4.5) and HPMC K4M concentrations (0-1 % w/v). The investigated dissolution media represented the consumption of different alcoholic beverages, the pH of fasted and fed states, and a range of viscosity resembling diluted homogenized FDA meal. The dissolution efficiency and the time to 50 % release (t50%) were selected as release parameters. It was found that both ethanol concentration and medium pH affected drug release from SA matrix tablets and the swelling of SA compacts. Dose dumping occurred at high ethanol concentration (40 %) at both media pH with almost complete drug release within 15-30 min associated with rapid matrix disintegration. HPMC at 0.5-1 % concentrations increased the medium's viscosity, preventing dose dumping at high ethanol concentrations. Erosion and disintegration of SA compacts were decelerated by increasing HPMC concentration in hydroethanolic media in consonance with decreased release rate from matrix tablets. ANOVA tests showed significant effects of pH and concentrations of ethanol and HPMC in the dissolution medium on the release parameters.

Abstract
INTRODUCTION As a nature-derived polymer with swelling and gelling properties, alginate has found wide biopharma-relevant applications. However, there is comparatively limited attention on alginate in tablet formulations. Therefore, this review aimed to provide an overview of the applications of alginate in solid dosage form formulations. AREAS COVERED This review outlines the role of alginate for oral sustained release formulations. For better insights into its application in drug delivery, the mechanisms of drug release from alginate matrices are discussed alongside the alginate inherent properties and drug properties. Specifically, the influence of alginate properties and formulation components on the resultant alginate gel and subsequent drug release is reviewed. Modifications of the alginate to improve its properties in modulating drug release are also discussed. EXPERT OPINION Alginate-based matrix tablets is useful for sustaining drug release. As a nature-derived polymer, batch consistency and stability raise some concerns about employing alginate in formulations. Furthermore, the alginate gel properties can be affected by formulation components, pH of the dissolution environment and the tablet matrix micro-environment pH. Conscientious efforts are pivotal to addressing these formulation challenges to increase the utilization of alginate in oral solid dosage forms.

Abstract
OBJECTIVE Development and evaluation of bucco-adhesive films of Gliclazide for pediatric use. METHODS Sixteen films were formulated using a different combination of Gelatin, Hydroxy propyl methyl cellulose (HPMC), polyvinyl alcohol, Hydroxy propyl cellulose (HPC), chitosan, polyethylene glycol, sodium alginate, and carbopol. Compatibility study for drug and polymers was conducted using differential scanning calorimetry method and Fourier transform infrared spectroscopy. All films were examined for drug content, weight variation, thickness, swelling index, muco-adhesion and folding endurance. In vitro drug release has been completed for two hours. Stability studies were conducted at 4°C, 25°C, and 40°C for selected films. The optimized formulation based on in vitro data was selected for a bioavailability study in rabbits. RESULTS The selected film formula (carbopol 2%, HPMC 2%) did not demonstrate interactions between the drug and polymers, while it showed accepted content, muco-adhesion, and mechanical properties. The in vitro release study showed rapid and complete release of drug from films. Stability studies confirmed accepted stability of the selected film at 4°C and 25°C, but the film get hard with few particles at 40°C. The bioavailability studies conducted showed that there was 2.1 fold increase in the AUC0-24 of selected film compared with oral tablets. CONCLUSION Bucco adhesive films of Gliclazide is a promising dosage form for the treatment of diabetes in children.

Tailoring of Rosuvastatin Calcium and Atenolol Bilayer Tablets for the Management of Hyperlipidemia Associated with Hypertension: A Preclinical Study. Pharmaceutics 2022; 14:pharmaceutics14081629. [PMID: 36015255 PMCID: PMC9412892 DOI: 10.3390/pharmaceutics14081629] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 07/22/2022] [Accepted: 07/28/2022] [Indexed: 01/20/2023] Open
Abstract
Hyperlipidemia is still the leading cause of heart disease in patients with hypertension. The purpose of this study is to make rosuvastatin calcium (ROS) and atenolol (AT) bilayer tablets to treat coexisting dyslipidemia and hypertension with a single product. ROS was chosen for the immediate-release layer of the constructed tablets, whereas AT was chosen for the sustained-release layer. The solid dispersion of ROS with sorbitol (1:3 w/w) was utilized in the immediate-release layer while hydroxypropyl methylcellulose (HPMC), ethylcellulose (EC), and sodium bicarbonate were incorporated into the floating sustained-release layer. The concentrations of HPMC and EC were optimized by employing 32 full factorial designs to sustain AT release. The bilayer tablets were prepared by the direct compression method. The immediate-release layer revealed that 92.34 ± 2.27% of ROS was released within 60 min at a pH of 1.2. The second sustained-release layer of the bilayer tablets exhibited delayed release of AT (96.65 ± 3.36% within 12 h) under the same conditions. The release of ROS and AT from the prepared tablets was found to obey the non-Fickian diffusion and mixed models (zero-order, Higuchi and Korsmeyer–Peppas), respectively. Preclinical studies using rabbit models investigated the impact of ROS/AT tablets on lipid profiles and blood pressure. A high-fat diet was used to induce obesity in rabbits. Bilayer ROS/AT tablets had a remarkable effect on decreasing the lipid profiles, slowing weight gain, and lowering blood pressure to normal levels when compared to the control group.

Abstract
BACKGROUND The rutin loaded chitosan-alginate nanoparticles (RCANP) were prepared using an ion gelation method. The optimized RCANP4 formulation composed of rutin: alginate: chitosan with the ratio of 1.24:5:2. The particle size, zeta potential, and entrapment efficiency of RCANP4 formulation were found to be 168.4 ± 11.23 nm, -24.7 ± 1.5 mV, and 91.23 ± 1.1%, respectively. The in vitro drug release of RCANP4 formulation was found to be 88.89 ± 2.9% within 24 h. The Fourier transform infrared spectroscopy (FT-IR) of RCANP4 revealed all characteristic groups of rutin, confirming the successful loading of rutin into the nanoparticles. <P> Background: The rutin loaded chitosan-alginate nanoparticles (RCANP) were prepared using an ion gelation method.

Abstract
This paper presents the characteristics, morphology, and properties of alginate/chitosan/polyphenol nanoparticles, in which polyphenols were extracted from Camellia chrysantha leaves collected in Tam Dao district, Vinh Phuc province (Vietnam). The alginate/chitosan/polyphenol nanoparticles were prepared by ionic gelation method at different polyphenol content. The characteristics and morphology of these nanoparticles were investigated using infrared spectroscopy (IR), ultraviolet-visible spectroscopy (UV-Vis), and scanning electron microscopy (SEM). Release kinetic of polyphenols from the alginate/chitosan/polyphenol nanoparticles was conducted in simulated human body fluids. The release kinetics of polyphenols from the above nanoparticles were also evaluated and discussed. The experimental results showed that the release process of polyphenols from the nanoparticles was dependent on three factors: time, pH of solution, and amount of polyphenols.

Abstract
Bio-inspired nanotechnology-based strategies are potential platforms for enhanced dissolution and oral biovailability of poorly water-soluble drugs. In this study, a recently patented green biopolymer (Prosopis africana gum, PG) was compatibilized with microcrystalline cellulose (MCC), a conventional polysaccharide, via thermo-regulated coacervation to obtain PG-MCC (1:0, 1:1, 1:2, 2:1, and 0:1) rational blends and the nanoparticles developed with optimized (1:1) biocomposites (termed "prosopisylated cellulose") by combined homogenization-nanoprecipitation technique was engineered as a high circulating system for improved oral bioavailability of griseofulvin (GF), a model Biopharmaceutics Classification System (BCS) Class-II drug. The effects of biopolymer interaction on morphological and microstructural properties of drug-free biocomposites obtained were investigated by Fourier transform infra-red spectroscopy, scanning electron microscopy and x-ray diffractometry, while the physicochemical properties and in-vivo pharmacokinetics of GF-loaded nanoparticles were also ascertained. Optimized biocomposites revealed inter-molecular and intra-molecular hydrogen bonding between the hydroxyl group of MCC and polar components of PG, as well as reduction in crystallinity of MCC. Griseofulvin-loaded nanoparticles were stable, displayed particles with relatively smooth surfaces and average size of 26.18 ± 0.94 . nm, with zeta potential and polydispersity index of 32.1 ± 0.57 mV and 0.173 ± 0.06, respectively. Additionally, the nanoparticles showed good entrapment efficiency (86.51 ± 0.93 %), and marked improvement in griseofulvin dissolution when compared to free drug, with significantly (p < 0.05) higher GF release in basic than acidic PEG-reinforced simulated bio-microenvironments. Besides, x-ray diffractogram of GF-loaded nanoparticles showed amorphization with few characteristic peaks of GF while infra-red spectrum indicated broader principal peaks of GF and components compatibility. Furthermore, GF-loaded nanoparticles showed low plasma clearance with three-fold increase in systemic bioavailability of griseofulvin compared with free drug. These results showed that prosopisylated cellulose nanoparticles would be a facile approach to improve oral bioavailability of BCS class-II drugs and can be pursued as a new versatile drug delivery platform.

Abstract
Scar free healing together with pain management is one of the major considerations in full thickness wound healing. Extensive wounds take longer to heal without any clinical intervention and, hence, need natural or artificial extracellular matrix support for quick skin regeneration. To address these issues, medicated 3D porous biomimetic scaffolds were developed with a unique combination of biopolymers, that is, chitosan, sodium alginate, and elastin, supplemented with a non-steroidal anti-inflammatory drug (NSAID). Scaffolds were physically characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), swelling ratio analysis, and degradation studies. Findings of the performed analyses proved that these skin substitutes suitable for skin tissue engineering applications attributable to their nano-microporous structures (pore size in range of 0.085-256 μm) allowing cell infiltration and high-water absorption capacity for management of wound exudates. Optimal dose of the loaded ibuprofen was estimated by evaluating effect of variable concentrations of ibuprofen (control, ILM-10, ILM-15, and ILM-20) on adipose tissue-derived mesenchymal stem cells (ASCs) proliferation rate. Out of all experimental groups, ILM-20 constructs were found to accelerate the proliferation rate of seeded ASCs confirming their non-cytotoxic characteristics as well potential to be used for translational scaffold-based therapies.

Abstract
Objective: The main aim of this research work was to develop and evaluate cost effective modified release tablets of Capecitabine (CAP) without utilizing coating techniques.Methods: The tablets were prepared by non-aqueous wet granulation method. Hydroxypropyl cellulose (HPC) was used as an extended release matrix former and sodium alginate (SA) was used as sustained release agent due to its gel forming ability. 32 full factorial design was used to study the effect of the independent variables i.e. HPC and SA on dependent variables, in vitro drug release and swelling index. The physiochemical properties of the drug were analyzed by ultraviolet (UV), fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and powder X-ray diffraction (P-XRD). The formulated tablets were evaluated for hardness, thickness, weight variation, content uniformity, swelling index, and in vitro drug release study.Results: The FTIR and DSC studies confirmed that there was no any interaction between drug, polymers and excipients. Also from DSC and P-XRD studies it was clear that the crystalline nature of CAP was remain unchanged in the optimized formulation tablet. Formulation F8 retarded the drug release up to 24 h with the optimum concentration of the both the polymers.Conclusion: We have successfully developed the modified release tablets of CAP with the combination of diffusion and erosion controlled type of drug release mechanism.

Abstract
Composite silica-alginate nanoparticles were prepared via silica sol-gel technique using a water-in-oil microemulsion system. In our system, cyclohexane served as the bulk oil phase into which aqueous solutions of sodium alginate were dispersed as droplets that confined nanoparticle formation after addition of tetraethylorthosilicate (TEOS). Our studies showed that much of the particle growth is completed within the first 24 hours and reaction times up to 120 hours only resulted in an additional 5% increase in particle diameter. Average particle size was found to decrease with increasing water-to-surfactant molar ratio (R) and with increasing cocentration of alginate in the aqueous phase. The potential for drug loading during particle formation was demonstrated using rhodamine B as a model drug. In vitro release studies showed that particles incubated in pH 2.5 phosphate buffer released only about 7% of the drug load in 27 days, while 42% was released in pH 7.5 phosphate buffer over the same period. Analysis of the release profile suggested that rhodamine B was homogeneously distributed throughout the particle and that the drug diffusivity was 40-fold greater in pH 7.5 buffer compared to that at pH 2.5. These results suggest that silica-alginate nanoparticles could be used as a pH-responsive drug carrier for controlled drug release.

Abstract
The objective of this study was to modify the release of two drugs having different solubility in a combined matrix tablet as a fixed-dose combination for extended release. Propranolol HCl (freely soluble) and carbamazepine (very slightly soluble) were used as model drugs, water-soluble hydroxypropyl methylcellulose (HPMC) and water-insoluble ethylcellulose (EC) were used as matrix-forming polymers. Tablets were prepared by direct compression of powder blends, or propranolol HCl was first granulated with one of the matrix-forming polymers (1:1) followed by compression with carbamazepine and matrix former. Propranolol HCl release from directly compressed tablets was faster than carbamazepine because of its higher solubility. The release of both drugs was fast when HPMC-propranolol HCl granules were compressed with carbamazepine into EC matrix tablet. Conversely, the release of both drugs was decreased when HPMC-propranolol HCl granules and carbamazepine were compressed into HPMC matrices. The desired release of both drugs was approached when EC-propranolol HCl granules were compressed with carbamazepine into HPMC matrix. Erosion of the HPMC matrix and, therefore, drug release were adjusted by varying the molecular weight of HPMC. A burst release of propranolol HCl decreased when it was granulated with EC in a fluidized bed coater followed by compression with carbamazepine into HPMC matrix.

Abstract
In the past many research studies have focused on the thiazolidine-4-one scaffold, due to the important biological effects associated with its heterocycle. This scaffold is present in the structure of many synthetic compounds, which showed significant biological effects such as antimicrobial, antifungal, antioxidant, anti-inflammatory, analgesic, antidiabetic effects. It was also identified in natural compounds, such as actithiazic acid, isolated from Streptomyces strains. Starting from this scaffold new xanthine derivatives have been synthetized and evaluated for their antibacterial and antifungal effects. The antibacterial action was investigated against Gram positive (Staphyloccoccus aureus ATCC 25923, Sarcina lutea ATCC 9341) and Gram negative (Escherichia coli ATCC 25922) bacterial strains. The antifungal potential was investigated against Candida spp. (Candida albicans ATCC 10231, Candida glabrata ATCC MYA 2950, Candida parapsilosis ATCC 22019). In order to improve the antimicrobial activity, the most active xanthine derivatives with thiazolidine-4-one scaffold (XTDs: 6c, 6e, 6f, 6k) were included in a chitosan based polymeric matrix (CS). The developed polymeric systems (CS-XTDs) were characterized in terms of morphological (aspect, particle size), physic-chemical properties (swelling degree), antibacterial and antifungal activities, toxicity, and biological functions (bioactive compounds loading, entrapment efficiency). The presence of xanthine-thiazolidine-4-one derivatives into the chitosan matrix was confirmed using Fourier transform infrared (FT-IR) analysis. The size of developed polymeric systems, CS-XTDs, ranged between 614 µm and 855 µm, in a dry state. The XTDs were encapsulated into the chitosan matrix with very good loading efficiency, the highest entrapment efficiency being recorded for CS-6k, which ranged between 87.86 ± 1.25% and 93.91 ± 1.41%, depending of the concentration of 6k. The CS-XTDs systems showed an improved antimicrobial effect with respect to the corresponding XTDs. Good results were obtained for CS-6f, for which the effects on Staphylococcus aureus ATCC 25923 (21.2 ± 0.43 mm) and Sarcina lutea ATCC 9341 (25.1 ± 0.28 mm) were comparable with those of ciprofloxacin (25.1 ± 0.08 mm/25.0 ± 0.1 mm), which were used as the control. The CS-6f showed a notable antifungal effect, especially on Candida parapsilosis ATCC 22019 (18.4 ± 0.42 mm), the effect being comparable to those of nystatin (20.1 ± 0.09 mm), used as the control. Based on the obtained results these polymeric systems, consisting of thiazolidine-4-one derivatives loaded with chitosan microparticles, could have important applications in the food field as multifunctional (antimicrobial, antifungal, antioxidant) packaging materials.

Zhu Q, Mao S. Enhanced drug loading efficiency of contact lenses via salt-induced modulation. Asian J Pharm Sci 2018; 14:204-215.

Abstract
Low drug loading efficiency is one of the main obstacles hindering the application of contact lenses (CLs) as the carrier for extended ocular drug delivery. Here in this study, a simple and effective drug loading method based on salt induced modulation was proposed and demonstrated with mechanism elucidation. First of all, using poly (2-hydroxyethyl methacrylate) (p-HEMA) as the contact lens material, betaxolol hydrochloride, Diclofenac Sodium and Betaxolol Base as the model drugs with different solubility, influence of salt concentration, salt type (sodium salts of sulfate, chloride, and sulfocyanate) and drug properties in the loading solution on drug loading efficiency was investigated. Mechanism of enhanced drug loading in contact lens was further explored via studying the influence of salt on the absorption isotherm, drug solubility and water content of CLs. Applicability of this method to other CLs materials was also investigated. It was demonstrated that adjusting the ionic strength of loading solutions resulted in significant increase of drug loading in CLs. Type and concentration of the salts and solubility of the drug were the main factors influencing enhancement ratio of drug loading. The mechanism for improved drug loading was related to the reduced drug solubility in loading solutions and the reduced bound water content in contact lenses. Modulation of drug loading by adjusting ionic strength was also applicable to other CLs and the light transmittance was not affected. This method was more suitable for salt-form drugs with high solubility. In summary, adjusting ionic strength of loading solution is an economical and effective way to improve drug loading in CLs, and this simple method may also find application in other hydrogel based drug delivery systems.

Abstract
AIM The preparation of a delivery system able to guarantee a delayed release of lovastatin from red yeast rice (RYR) is mandatory to counteract cholesterol biosynthesis effectively. MATERIALS & METHODS Polymeric formulations were prepared mixing alginate and gelatin, in different ratios, with RYR. The effect of different composition on stiffness, viscosity, swelling behavior and mesostructure of matrices was analyzed. RESULTS Formulations obtained combining polymers in comparable amount (i.e., 60/40 and 50/50) guaranteed a delayed release of lovastatin from RYR, a prolonged inhibitory activity toward 3-hydroxy-3-methylglutaryl-coenzyme A reductase and a decreased cholesterol synthesis. CONCLUSION The formulation obtained combining 60% gelatin and 40% of alginate showed physicochemical properties suitable to lead a lovastatin release profile compatible with cholesterol biosynthesis.

Abstract
The objective of this study is to design sustained-release tablets using matrix technology, which can well control the release of highly water-soluble drugs with good system robustness and simple preparation process. Taking venlafaxine hydrochloride (VH) as a drug model, the feasibility of using chitosan (CS), carbomer (CBM) combination system to achieve this goal was studied. Formulation and process variables influencing drug release from CS-CBM matrix tablets were investigated. It was found that CS-CBM combination system weakened the potential influence of CS, CBM material properties and gastric emptying time on drug release profile. Demonstrated by direct observation, differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR), in situ self-assembled polyelectrolyte complex (PEC) film was formed on the tablet surface during gastrointestinal tract transition, which contributed to the tunable and robust control of drug release. The sustained drug release behavior was further demonstrated in vivo in Beagle dogs, with level A in vitro and in vivo correlation (IVIVC) established successfully. In conclusion, CS-CBM matrix tablets are promising system to tune and control the release of highly water-soluble drugs with good system robustness.

Preparation of astaxanthin-loaded DNA/chitosan nanoparticles for improved cellular uptake and antioxidation capability. Food Chem 2017; 227:9-15.

Abstract
DNA/chitosan co-assemblies were initially used as nanocarriers for efficient astaxanthin encapsulation and delivery. The obtained astaxanthin-loaded DNA/chitosan (ADC) colloidal system was transparent and homogenous, with astaxanthin content up to 65μg/ml. Compared to free astaxanthin, ADC nanoparticles with an astaxanthin concentration as low as 3.35nM still showed a more powerful cytoprotective effect on H2O2-induced oxidative cell damage, and improved cell viability from 49.9% to 61.9%. The ROS scavenging efficiency of ADC nanoparticles was as high as 54.3%, which was 2-fold higher than that of free astaxanthin. Besides this, ADC nanoparticles were easily engulfed by Caco-2 cells in a short time, indicating that the encapsulated astaxanthin could be absorbed through endocytosis by intestinal epithelial cells. The improved antioxidation capability and facilitated cellular uptake enabled the ADC nanoparticles to be good candidates for efficient delivery and absorption of astaxanthin.

Functional Performance of Chitosan/Carbopol 974P NF Matrices in Captopril Tablets. JOURNAL OF PHARMACEUTICS 2016; 2016:3240290.

Abstract
Chitosan and Carbopol have been used to form a complex through an electrostatic interaction between the protonated amine (NH3+) group of chitosan and the carboxylate (COO−) group of Carbopol. In situ polyelectrolyte complexes formations based on the physical mixture of chitosan and sodium alginate were found and could be used as an oral controlled release matrix. The aim of this work is the assessment of a possible interaction between the particles of chitosan and Carbopol 974P NF that could modify their technological performance in captopril tablets. The drug and excipients were evaluated as mixtures of powders and tablets. The mixtures with captopril contained Carbopol 974P NF, chitosan, or a 1 : 1 mixture thereof with polymer proportions of 10%, 20%, and 30%. The evaluated parameters were the powder flow rate, the powder compressibility index, and the compactibility and release behavior of the tablets. The observed technological behavior points out to a greater interaction between the particles of polymers with different charge than between particles of the individual polymers. This produces more coherent matrices restricting more efficiently the drug dissolution, more coherent tablets with higher compactibility, and less flowing powder mixtures. All this, however, requires additional investigation to confirm the current results.
