Abstract
Rivaroxaban (RXN) finds use in the management of pulmonary embolism and deep vein thrombosis. Its poor solubility (5-7 µg/mL) and P-gp-mediated efflux from intestinal lining limits the oral application of RXN. This work assessed the impact of liquisolid compact technique in augmenting the solubility and bioavailability of RXN. PEG 400, Avicel PH 200, and Aerosil 200 were used as non-volatile liquid, carrier, and coating material, respectively, to formulate RXN liquid-solid compacts (RXN LSCs). A 32-factor factorial design was used in the optimisation to assess the impacts of factors (load factor and carrier:coating ratio) on the responses (angle of repose and Q30 min). Pre-compression parameters of RXN LSCs suggested adequate flow and compressibility. Optimisation data suggested significant influence of factors on both the responses. Optimised RXN LSC-based tablets showed a significantly higher in vitro dissolution rate than RXN API and Xarelto® tablets due to improved solubility, reduced crystallinity, greater surface area, and enhanced wetting of RXN particles. XRD, DSC, and SEM data supported RXN's amorphization. The cytotoxicity (MTT assay) and permeation studies indicated the nontoxicity of prepared RXN LSC tablets and the role of PEG 400 in inhibiting P-gp. Pharmacokinetic study of RXN LSC-based tablets in Albino Wistar rats exhibited 2.51- and 1.66-times higher AUC in comparison to RXN API and Xarelto® tablets respectively, demonstrating that developed formulation had a greater oral bioavailability. The RXN LSC tablets showed longer bleeding times and higher rates of platelet aggregation than RXN API. Thus, RXN LSC tablets can be considered a facile, scalable technology.

Drug Deliv Transl Res 2022; 12:3029-3046. [PMID: 35467325 DOI: 10.1007/s13346-022-01168-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/15/2022] [Indexed: 12/16/2022]
Abstract
The objective of the present study was to evaluate the potential of solid dispersion adsorbate (SDA) to improve the solubility and bioavailability of rivaroxaban (RXN). SDA of RXN was developed by fusion method using PEG 4000 as carrier and Neusilin as adsorbent. A 32 full factorial design was utilized to formulate various SDAs. The selected independent variables were the amount of carrier (X1) and amount of adsorbent (X2). The responses measured were the time required for 85% drug release (Y1) and saturated solubility (Y2). MTT assay was employed for cytotoxicity studies on Caco-2 cells. In vivo pharmacokinetics and pharmacodynamic evaluations were carried out to assess the prepared SDA. Pre-compression evaluation of SDA suggests the prepared batches (B1-B9) possess adequate flow properties and could be used for compression of tablets. Differential scanning calorimetry and X-ray diffraction data signified the conversion of the crystalline form of drug to amorphous form, a key parameter accountable for improvement in drug dissolution. Optimization data suggests that the amount of carrier and amount of adsorbent significantly (P < 0.05) influence both dependent variables. Post-compression data signifies that the compressibility behavior of prepared tablets was within the official standard limits. A significant increase (P < 0.0001) in the in vitro dissolution characteristics of RXN was noticed in optimized SDA (> 85% in 10 min) as compared to the pure drug, marketed product, and directly compressible tablet. Cytotoxicity studies confirmed the nontoxicity of prepared RXN SDA tablets. RXN SDA tablets exhibited 2.79- and 1.85-fold higher AUC in comparison to RXN suspension and Xarelto tablets respectively indicating improved oral bioavailability. Higher bleeding time and percentage of platelet aggregation noticed with RXN SDA tablets in comparison to RXN suspension further substantiate the efficacy of the prepared formulation. In summary, the results showed the potential of RXN SDA tablets to enhance the bioavailability of RXN and hence can be an alternate approach of solid dosage form for its development for commercial application.

Abstract
Due to poor solubility and stability in acid conditions, the gastrointestinal administration of stiripentol (STP) is still a significant challenge. This study aimed to explore the applicability of effervescent tablets compressed from STP-loaded enteric solid dispersions to improve the solubility and stability of the insoluble and acid-labile drug. STP-loaded solid dispersions (STP-SDs) and the effervescent tablets (STP-SD-ETs) were prepared using solvent evaporation and dry granulation technology, respectively, and their formulations were optimized. Then, STP-SDs were characterized regarding solid state, in vitro release, stability, etc. Results showed that enteric amorphous STP-SDs were successfully prepared and significantly improved the solubility and stability of STP. Moreover, compared with STP suspensions, the bioavailability of STP-SD-ETs was as high as 138.71%. Concomitantly, STP-SD-ETs significantly increased the intestinal absorption rate of STP. Overall, the oral preparation encompassing enteric solid dispersion combined with effervescent tablet technology possesses excellent performance in enhancing dissolution, anti-acid hydrolysis stability, and absorption of STP. Our work provides a promising method to improve the delivery of drugs with poor solubility and acid-labile stability.

Biocompatible poly(ethylene succinate) polyester with molecular weight dependent drug release properties. Int J Pharm 2022; 618:121653. [PMID: 35278604 DOI: 10.1016/j.ijpharm.2022.121653] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Revised: 02/04/2022] [Accepted: 03/07/2022] [Indexed: 01/05/2023]
Abstract
In the present study, we demonstrate that well-known molecular weight-dependent solubility properties of a polymer can also be used in the field of controlled drug delivery. To prove this, poly(ethylene succinate) (PES) polyesters with polycondensation time regulated molecular weights were synthesized via catalyst-free direct polymerization in an equimolar ratio of ethylene glycol and succinic acid monomers at 185 °C. DSC and contact angle measurements revealed that increasing the molecular weight (Mw, 4.3-5.05 kDa) through the polymerization time (40-80 min) increased the thermal stability (Tm= ∼61-80 °C) and slightly the hydrophobicity (Θw= ∼27-41°) of the obtained aliphatic polyester. Next, this biodegradable polymer was used for the encapsulation of Ca2+ channel blocker Nimodipine (NIMO) to overcome the poor water solubility and enhance the bioavailability of the drug. The drug/ polymer compatibility was proved by the means of solubility (δ) and Flory-Huggins interaction (miscibility) parameters (χ). The nanoprecipitation encapsulation of NIMO into PES with increasing Mw resulted in the formation of spherical 270 ± 103 nm NIMO-loaded PES nanoparticles (NPs). Furthermore, based on the XRD measurements, the encapsulated form of NIMO-loaded PES NPs showed lower drug crystallinity, which enhanced not only the water solubility but even the water stability of the NIMO in an aqueous medium. The in-vitro drug release experiments demonstrated that the release of NIMO drug could be accelerated or even prolonged by the molecular weights of PES as well. Due to the low crystallinity of PES polyester and low particle size of the encapsulated NIMO drug led to enhance solubility and releasing process of NIMO from PES with lower Mw (4.3 kDa and 4.5 kDa) compared to pure crystalline NIMO. However, further increasing the molecular weight (5.05 kDa) was already reduced the amount of drug release that provides the prolonged therapeutic effect and enhances the bioavailability of the NIMO drug.

Abstract
Ticagrelor (TG) suffers from low peroral bioabsorption (36%) due to P-gp efflux and poor solubility (10 µg/mL). TG solid dispersion adsorbates (TG-SDAs) were formulated using an amalgamation of solid dispersion and melt adsorption techniques which were simple, economic, scalable, and solvent-free. FTIR indicated no incompatibility between drug and excipients. DSC, XRD, and SEM suggested a reduction in TG crystallinity. Q30min from TG-SUSP and TG-conventional tablets was only 2.30% and 6.59% respectively whereas TG-SDA-based tablets exhibited a significantly higher drug release of 86.47%. Caco-2 permeability studies showed 3.83-fold higher permeability of TG from TG-SDAs. TG-SDA-based tablets exhibited relative bioavailability of 748.53% and 153.43% compared to TG-SUSP and TG-conventional tablets respectively in rats. TG-SDA-based tablets were devoid of any cytotoxicity as indicated by MTT assay and exhibited better antiplatelet activity in rats. Enhanced oral bioavailability of TG-SDAs can be attributed to inhibition of P-gp efflux by PEG 4000, increased wettability, and reduced crystallinity of drug leading to improved drug solubility and dissolution. Improved bioabsorption results in a reduction of dose, cost of therapy as well as dose-related side effects. Thus, SDAs can be considered a promising and scalable approach for the improvement of dissolution rate and solubility of TG. TG-SDAs can be translated to an effective and safe dosage form, whereby its rapid onset of action promotes the prevention of heart attack, stroke, and related ill events in individuals with the acute coronary syndrome. However, scale-up, validation, and clinical-studies are necessary for confirmation of the proof-of-concept.

Abstract
Solid dispersions offer many advantages for oral drug delivery of poorly water-soluble drugs over other systems, including an increase in drug solubility and drug dissolution. An improvement in drug absorption and the higher bioavailability of active pharmaceutical ingredients in the gastrointestinal tract have been reported in various studies. In certain circumstances, a rapid pharmacological effect is required for patients. Fastdissolving solid dispersions provide an ideal formulation in such cases. This report will provide an overview of current studies on fast-dissolving solid dispersions, including not only solid dispersion powders with fast dissolution rates but also specific dose form for the controlled release of poorly water-soluble drugs. Specifically, the applications of fast-dissolving solid dispersions will be described in every specific case. Moreover, pharmaceutical approaches and the utilization of polymers will be summarized. The classification and analysis of fastdissolving solid dispersions could provide insight into strategies and potential applications in future drug delivery developments.

Abstract
Background Meloxicam (MLX) is a potent non-steroidal anti-inflammatory drug with poor solubility. Solid dispersion (SD) is an effective formulation strategy to improve the dissolution rate of poorly water-soluble compounds. Hydroxy propyl methyl cellulose (HPMC) as an inert polymer carrier and nicotinic acid (NA) as disturbance can be used as a matrix of SD. The aim of this study was to determine the effect of MLX-HPMC-NA SD on the solubility and dissolution of MLX. Methods SD was prepared by the solvent evaporation technique with methanol being used as a solvent. Methanol was evaporated at room temperature. SD of MLX was prepared involving various matrix compositions at MLX:HPMC:NA ratios of 1:1:1 (SD1), 1:1:2 (SD2), 1:2:1 (SD3), and 1:2:2 (SD4). Results The solubility profile of MLX in SD3 (64.34 ppm) showed a higher improvement than the physical mixture (15.99 ppm) and pure MLX (6.89 ppm). This increase might be due to the formation of molecular dispersion of MLX in the polymer as hydrophilic matrix and NA have both donor-acceptor sites for hydrogen bonding interactions. The dissolution profile of SD3 also showed the highest improvement. The melting endotherm of SD3 was detected at 219.5 °C, in which case it originated from NA rather than from MLX, showing that MLX was molecularly dispersed and amorphous. Conclusions MLX solubility and dissolution profile could be improved by the SD technique with a matrix of HPMC and NA. The best result was given by SD3 with an MLX:HPMC:NA ratio of 1:2:1. Based on the characterization study, it is predicted that hydrophilic polymer and hydrogen bonding interactions play important roles in MLX solubility or dissolution rate improvement.

Abstract
Background Solid dispersion (SD) represents a good method for enhancing the solubility of poorly water-soluble drugs. Meloxicam (MLX), a nonsteroidal anti-inflammatory drug has poor solubility in water. Hydroxypropyl methylcellulose (HPMC) 2910 3 cps, a hydrophilic carrier and nicotinamide (NC), a hydrotropic agent can be used as matrix of SD. The aim of this study is to investigate the effect of HPMC 2910 3 cps and NC as SD matrix on the solubility and dissolution rate of MLX. Methods The SD of MLX was prepared by solvent evaporation method using methanol as solvent. The SD formulations composed of HPMC and NC in different ratios (1:1:1, 1:1:2, 1:2:1, 1:2:2). The physical state of MLX SD were characterized by Differential Thermal Analyzer (DTA), Fourier Transform Infrared Spectroscopy, powder X-ray diffractometer (PXRD), Scanning Electron Microscopy (SEM). The solubility and dissolution of the MLX SD were also evaluated. Results The results of differential thermal analysis (DTA) showed that the melting point of MLX SD was lower than MLX further the X-ray diffractogram showed a decrease of the crystallinity of MLX in SD. Those indicated that MLX was dispersed molecularly in SD. The SD showed a widening transmission peak at 3000-3500 cm-1 which resembled the peak of pure MLX transmission. It indicated that intermolecular hydrogen bonds were formed between MLX, HPMC, and NC. The solubility and the dissolution efficiency (ED60) of SD with MLX-HPMC 2910 3 cps-NC = 1:2:1 increased 3.59 times and 1.50 times higher then MLX substance. Conclusions MLX-HPMC-NC SD system increased the solubility and dissolution of MLX. The SD with MLX-HPMC 2910 3 cps-NC ratio of 1:2:1 had the highest solubility and ED60 compared to the other SD formulas.

Abstract
The aim of this study was to investigate hydrophilic-hydrophobic conjugates as new carriers for nano-sized solid dispersions (SDs). The amphiphilic conjugates were prepared via an esterification reaction between hydroxypropyl methylcellulose (HPMC) and zein. Four formulations of conjugates were investigated with different ratios of zein to HPMC (1:5, 1:10, 1:20, and 1:40). Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy and particle size analyses were performed to characterize and optimize the formulation for SD. Isradipine and prednisolone were chosen as poorly water-soluble drugs for SD using the conjugate as a carrier. Dissolution tests, particle size analyses, powder X-ray diffraction and FTIR were conducted to determine the dissolution enhancement and its mechanism. The conjugate formed small particles as a self-assembled carrier. Although the SD with isradipine or prednisolone showed a small increase in particle size, the dissolution rate of those drugs in SD increased significantly compared to pure drugs. The interaction between the drug and conjugate was attributed to the formation of small particles and changes to the drug crystallinity. This study demonstrated that the hydrophilic-hydrophobic conjugate is a promising material for SD, with the potential of reducing drug particles to nano size in addition to promoting drug amorphousness or molecular interactions.
