Choi JE, Kim JS, Choi MJ, Baek K, Woo MR, Kim JO, Choi HG, Jin SG. Effects of different physicochemical characteristics and supersaturation principle of solidified SNEDDS and surface-modified microspheres on the bioavailability of carvedilol. Int J Pharm 2021; 597:120377. [PMID: 33581270 DOI: 10.1016/j.ijpharm.2021.120377] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 02/04/2021] [Accepted: 02/07/2021] [Indexed: 02/08/2023]
Abstract
In this study, a solidified self-nanoemulsifying drug delivery system (solidified SNEDDS) and surface-modified microspheres were developed for enhancing the oral bioavailability of carvedilol. Based on the aqueous solubility test, liquid SNEDDS was composed of Peceol™ (oil), Tween® 80 (surfactant), and Labrasol® (co-surfactant) at a weight ratio of 25/50/25, generating the smallest nanoemulsion droplet size. Then, carvedilol was added to liquid SNEDDS and spray-dried with Aerosil® to fabricate the solidified SNEDDS. Surface-modified microspheres were manufactured using copovidone (polymer) and Tween® 80 (surfactant) according to aqueous solubility test results. The proper ratio of copovidone and Tween® 80 was determined based on the solubility and dissolution test. Both prepared formulations and carvedilol powder were compared using four different criteria: physicochemical characteristics, solubility, dissolution, and oral bioavailability. For solidified SNEDDS, carvedilol was encapsulated in liquid SNEDDS and absorbed to the Aerosil® surface, leading to the conversion from a crystalline to an amorphous state. However, the drug maintained its crystal form in the surface-modified microspheres. Round and even-sized particles were attached to the rough surfaces of drug, suggesting that hydrophilic carriers adhered to the hydrophobic drug. All formulations significantly improved drug solubility, dissolution, plasma concentrations, Cmax, and AUC compared to carvedilol powder. The parameters were ranked in the following order: solidified SNEDDS > surface-modified microspheres > carvedilol powder. As a result, different solubility-increasing mechanisms provided differences in performance. For carvedilol, the formation of a nano-emulsion in solidified SNEDDS resulted in an efficient supersaturated state, leading to improved solubility (~6.1 fold), dissolution (~1.8 fold), and oral bioavailability (~1.4 fold) that was superior to the hydrophilic microenvironment in surface-modified microspheres.

Improved Bioavailability and High Photostability of Methotrexate by Spray-Dried Surface-Attached Solid Dispersion with an Aqueous Medium. Pharmaceutics 2021; 13:pharmaceutics13010111. [PMID: 33467157 PMCID: PMC7830624 DOI: 10.3390/pharmaceutics13010111] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 01/12/2021] [Accepted: 01/14/2021] [Indexed: 12/22/2022] Open
Abstract
Low aqueous solubility and poor bioavailability are major concerns in the development of oral solid-dosage drug forms. In this study, we fabricated surface-attached solid dispersion (SASD) to enhance the solubility, bioavailability, and photostability of methotrexate (MTX), a highly lipophilic and photo-unstable drug. Several MTX-loaded SASD formulations were developed for spray-drying using water as the solvent, and were investigated for their aqueous solubility and dissolution kinetics. An optimized ternary SASD formulation composed of MTX/ sodium carboxymethyl cellulose (Na-CMC)/sodium lauryl sulfate (SLS) at 3/0.5/0.5 (w/w) had 31.78-fold and 1.88-fold higher solubility and dissolution, respectively, than MTX powder. For SASD, the in vivo pharmacokinetic parameters AUC and Cmax were 2.90- and 3.41-fold higher, respectively, than for the MTX powder. Solid-state characterizations by differential scanning calorimetry and X-ray diffraction revealed that MTX exists in its crystalline state within the spray-dried SASD. The MTX-loaded SASD formulation showed few physical changes with photostability testing. Overall, the results indicate that the spray-dried MTX-loaded SASD formulation without organic solvents enhances the solubility and oral bioavailability of MTX without a significant deterioration of its photochemical stability.

Abstract
Generally, definite intestine targeting and immediate drug releasing are both important for the treatment of colon cancer via oral administration of anti-cancer drugs. We developed a highly specific oral colon-targeted pulsatile capsule, based on the effective enzyme-responsive 'pulse plug', which can be degraded under mannanase abundant in colon. Indomethacin (IN) solid dispersion immediate-release pellets were filled in an insoluble capsule body, a guar gum-lactose-hydroxypropyl methylcellulose (HPMC) composed tablet was embedded on the top of capsule as the 'pulse plug', and then covered by enteric soluble cap. In this study, the influence of the proportion of guar gum/lactose/HPMC, the viscosity of HPMC, and the tablet weight on the degradation behaviour of the plug tablet was investigated. The drug-releasing profiles of those pulsatile capsules in different simulated colon medium verified the 'pulse plug' could realise the colon-targeted pulsatile drug-releasing. Furthermore, the rabbit pharmacokinetic experiments showed that the in vivo time lag of drug loaded pulsatile capsules was significantly extended to 5.61 ± 0.08 h (p<.01), compared with that (0.33 ± 0.47 h) of the marketed tablets (YUNPENG®). These results indicated that colon-targeted pulsatile capsules would be effective oral delivering system for colon cancers therapy.

[PMID: 31236817 DOI: 10.1208/s12249-019-1446-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2019] [Accepted: 06/01/2019] [Indexed: 12/29/2022] Open
Abstract
The objective of this study is to explore the surface wettability modulated by a surfactant and its effects on the drug release and absorption of fenofibrate solid dispersions (FF SDs). Both the polyvinylpyrrolidone/sodium lauryl sulfate (PVP/SLS) coprecipitate and FF SDs were prepared by solvent evaporation method. The contact angle of PVP/SLS coprecipitate with various PVP/SLS weight ratios was determined to screen out the suitable content of SLS incorporated in FF SDs. Scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) was used to analyze the surface composition of the PVP/SLS coprecipitate, suggesting that SLS molecules were prone to concentrate on the carrier surface. The physicochemical characteristics of FF, PVP, SLS, FF SDs, and FF physical mixtures (PMs) were evaluated by thermal analysis, XRD, FTIR, and SEM, which revealed that FF was molecularly dispersed in SDs. The interaction between SLS and PVP or FF confirmed by FTIR would affect the surface morphology of SDs. Finally, the contact angle of FF SDs was measured to explore the effects of surface wettability on the dissolution behavior and drug absorption of FF SDs. The interesting thing is that the wettability of the PVP/SLS coprecipitate was positively related to that of FF SDs. The improved wettability of FF SDs or the PVP/SLS coprecipitate by adding SLS contributed to the slight enhancement of initial drug release and absorption, which implied that wettability would be a promising tool in the formulation studies.

Abstract
The purpose of this research was to develop a novel revaprazan-loaded surface-modified solid dispersion (SMSD) with improved drug solubility and oral bioavailability. The impact of carriers on aqueous solubility of revaprazan was investigated. HPMC and Cremophor A25 were selected as an appropriate polymer and surfactant, respectively, due to their high drug solubility. Numerous SMSDs were prepared with various concentrations of carriers, using distilled water, and the drug solubility of each was assessed. Moreover, the physicochemical properties, dissolution and pharmacokinetics of selected SMSD in rats were assessed in comparison to revaprazan powder. Of the SMSDs assessed, the SMSD composed of revaprazan/HPMC/Cremophor A25 at the weight ratio of 1:0.28:1.12 had the most enhanced drug solubility (∼6000-fold). It was characterized by particles with a relatively rough surface, suggesting that the carriers were attached onto the surface of the unchanged crystalline revaprazan powder. It had a significantly higher dissolution rate, AUC and Cmax, and a faster Tmax value in comparison to revaprazan powder, with a 5.3-fold improvement in oral bioavailability of revaprazan. Therefore, from an environmental perspective, this SMSD system prepared with water, and without organic solvents, should be recommended as a revaprazan-loaded oral pharmaceutical alternative.

Abstract
The purpose of this work is to investigate the effects of polymer/surfactant as carriers on the solubility and dissolution of fenofibrate solid dispersions (FF SDs) with the aid of systematic research on the physicochemical properties of the polymer/surfactant system and further highlight the importance of studying polymer/surfactant interaction in the preformulation. The critical micelle concentration (CMC) of sodium lauryl sulfate (SLS) and critical aggregation concentration (CAC) of polymer/SLS solutions were obtained through conductivity measurement. Meanwhile, surface tension, viscosity, morphology, and wettability of polymer/SLS with different weight ratios of SLS were analyzed to screen out the suitable content of SLS (weight%, 5% in carriers) incorporated in SDs. Polymer/SLS coprecipitate and FF SDs were prepared by the solvent evaporation method. The results from differential scanning calorimetry (DSC) and X-ray diffraction (XRD) analysis showed that FF was molecularly dispersed in SDs. Compared to the solubility of FF in povidone/SLS (PVP/SLS) solutions, the increment of FF solubility in copovidone/SLS (VA64/SLS) solutions was due to the formation of free SLS micelles, which have been confirmed by transmission electron microscopy (TEM). Particularly, the wettability of FF SDs and physical mixtures (PMs) was also determined by the sessile drop technique. A linear relationship between the wettability of carriers and that of FF SDs was found, which revealed the significant role of carriers on the surface composition of FF SDs. As the molecular weight of PVP increased, the wettability of carriers decreased, thus leading to the reduction of the dissolution rate of SDs. Although the presence of SLS did not enhance the dissolution of FF SDs, it increased the amount of drug released at the initial stage. All these results indicated that the polymer/SLS interaction would affect the performance of SDs; hence, it was necessary to study their properties in the preformulation.

Abstract
To develop a novel revaprazan-loaded gelatine microsphere with enhanced solubility and oral bioavailability, numerous gelatine microspheres were prepared using a spray-drying technique. The impact of gelatine amount on drug solubility in the gelatine microspheres was investigated. The physicochemical properties of the selected gelatine microsphere, such as shape, particle size and crystallinity, were evaluated. Moreover, its dissolution and pharmacokinetics in rats were assessed in comparison with revaprazan powder. Amongst the gelatine microspheres tested, the gelatine microsphere consisting of revaprazan and gelatine (1:2, w/w), which gave about 150-fold increased solubility, had the most enhanced drug solubility. It provided a spherical shape, amorphous drug and reduced particle size. Furthermore, it gave a higher dissolution rate and plasma concentration than did revaprazan powder. Particularly, it gave about 2.3-fold improved oral bioavailability in comparison with revaprazan powder. Therefore, this novel gelatine microsphere system is recommended as an oral pharmaceutical product of poorly water-soluble revaprazan.

Abstract
The aim of this research was to compare three strategies for enhancing the solubility of poorly water-soluble revaprazan hydrochloride: solid dispersion, solid SNEDDS and inclusion compound. The influence of polymers, surfactants and oils on the drug solubility was assessed, and via the chosen carriers, the three types of formulations were prepared utilising spray drying technique. Their physicochemical properties, solubility, dissolution and pharmacokinetics in rats were performed compared with revaprazan powder. Among the liquid SNEDDS formulations assessed, the compositions of revaprazan, peceol, Tween 80 and Labrasol (10:15:55:30, weight ratio) provided the smallest emulsion size. Moreover, this liquid SNEDDS and dextran were suspended/dissolved in distilled water, and spray-dried, producing an optimal revaprazan-loaded solid SNEDDS. The appropriate solid dispersion and inclusion compound were composed of revaprazan, hydroxypropylmethylcellulose and cremophor A25 (5:1.4:5.6) and drug and hydroxyl-β-cyclodextrin (2.5:8.77), respectively. The crystalline drug was converted to an amorphous state in all formulations. In the solid dispersion, the drug was attached to the hydrophilic carrier. The solid SNEDDS and inclusion compound contained aggregate microspheres and separate microspheres, respectively. All formulations significantly increased the drug solubility, dissolution, plasma concentration and AUC compared with revaprazan powder. These properties were ranked in the order solid dispersion ≥ solid SNEDDS > inclusion compound. Particularly, the solid dispersion improved about 9500-fold drug solubility and 10-fold oral bioavailability. Thus, the improved properties were considerably dependent upon these techniques, although all of the techniques employed similar mechanisms. Among the strategies checked, the solid dispersion system would be recommended as an oral revaprazan-loaded pharmaceutical product.

Abstract
The purpose of this study was to compare the powder properties, solubility, dissolution and oral absorption of solvent-wetted (SWSD) and kneaded (KNSD) l-sulpiride-loaded solid dispersions. The SWSD and KNSD were prepared with silicon dioxide, sodium laurylsulfate and D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) using a spray dryer and high shear mixer, respectively. Their powder properties, solubility, dissolution and oral absorption were assessed compared to l-sulpiride powder. The drug in SWSD was in the amorphous state; however, in KNSD, it existed in the crystalline state. The SWSD with a drug/sodium laurylsulphate/TPGS/silicon dioxide ratio of 5/1/2/12 gave the higher drug solubility and dissolution compared to the KNSD with the same composition. The oral absorption of drug in the SWSD was 1.4 fold higher than the KNSD and 3.0 fold higher than the l-sulpiride powder (p<0.05) owing to better solubility and reduced crystallinity. Furthermore, the SWSD at the half dose was bioequivalent of commercial l-sulpiride-loaded product in rats. Thus, the SWSD with more improved oral absorption would be recommended as an alternative for the l-sulpiride-loaded oral administration.

Abstract
The objective of this study is to explore the influence of polyvinylpyrrolidone (PVP) quantity on the solubility, crystallinity and oral bioavailability of poorly water-soluble fenofibrate in solvent-evaporated microspheres. Numerous microspheres were prepared with fenofibrate, sodium lauryl sulphate (SLS) and PVP using the spray-drying technique. Their aqueous solubility, dissolution, physicochemical properties and pharmacokinetics in rats were assessed. The drug in the solvent-evaporated microspheres composed of fenofibrate, PVP and SLS at the weight ratio of 1:0.5:0.25 was not entirely changed to the amorphous form and partially in the microcrystalline state. However, the microspheres at the weight ratio of 1:4:0.25 provided the entire conversion to the amorphous form. The latter microspheres, with an improvement of about 115 000-fold in aqueous solubility and 5.6-fold improvement in oral bioavailability compared with the drug powder, gave higher aqueous solubility and oral bioavailability compared with the former. Thus, PVP quantity played an important role in these properties of fenofibrate in the solvent-evaporated microspheres.
