Abstract
Many active pharmaceutical ingredients (API) are poorly soluble in water and their low oral bioavailability is a major hindrance to their potential use. Megestrol acetate (MGA) is insoluble in water and its oral absorption is limited and considerably affected by food. Nanoemulsions (NEs) can be used as effective oral drug delivery systems where the hydrophobic API is loaded into the oil phase. In this study, MGA-loaded NEs were prepared based on the spontaneous emulsification technique. The effects of different excipients such as ethanol, Tween 80, Lipoid E80, and medium-chain triglyceride (MCT) on the NEs characterization were investigated. The experimental results indicated that optimum MGA-loaded NEs (F20) were nanometer-sized droplets (166.9 ± 3.0 nm) with negative zeta potential (-12.2 ± 1.1 mV). The effect of polyvinylpyrrolidone (PVP) on characteristic properties of F20 was also evaluated. On the selected NEs, in vitro dissolution tests and stability studies in various mediums and storage conditions were performed. The encapsulation efficiency of NEs were > 99%. The overall droplet size of F20 and PVP-2 (PVP-coated NEs) remained relatively stable as the pH changed from 1.2 to 6.8. It was determined that F20 and PVP-2 remained stable at 4°C until 12 weeks and had higher cytotoxicity on MCF-7 cells. To conclude, droplet size, surface charge, and stability are important properties for NEs to have sufficient effectiveness. In this study, alternative oral NEs of low-solubility drug MGA were developed considering the above features.

Preparation and Characterization of Fenofibrate Microparticles with Surface-Active Additives: Application of a Supercritical Fluid-Assisted Spray-Drying Process. Pharmaceutics 2021; 13:pharmaceutics13122061. [PMID: 34959341 PMCID: PMC8709266 DOI: 10.3390/pharmaceutics13122061] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Revised: 11/25/2021] [Accepted: 11/26/2021] [Indexed: 11/17/2022] Open
Abstract
In this study, supercritical fluid-assisted spray-drying (SA-SD) was applied to achieve the micronization of fenofibrate particles possessing surface-active additives, such as d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS), sucrose mono palmitate (Sucroester 15), and polyoxyethylene 52 stearate (Myrj 52), to improve the pharmacokinetic and pharmacodynamic properties of fenofibrate. For comparison, the same formulation was prepared using a spray-drying (SD) process, and then both methods were compared. The SA-SD process resulted in a significantly smaller mean particle size (approximately 2 μm) compared to that of unprocessed fenofibrate (approximately 20 μm) and SD-processed particles (approximately 40 μm). There was no significant difference in the effect on the particle size reduction among the selected surface-active additives. The microcomposite particles prepared with surface-active additives using SA-SD exhibited remarkable enhancement in their dissolution rate due to the synergistic effect of comparably moderate wettability improvement and significant particle size reduction. In contrast, the SD samples with the surface-active additives exhibited a decrease in dissolution rate compared to that of the unprocessed fenofibrate due to the absence of particle size reduction, although wettability was greatly improved. The results of zeta potential and XPS analyses indicated that the surface-active additive coverage on the surface layer of the SD-processed particles with a better wettability was higher than that of the SA-SD-processed composite particles. Additionally, after rapid depletion of hydrophilic additives that were excessively distributed on the surfaces of SD-processed particles, the creation of a surface layer rich in poorly water-soluble fenofibrate resulted in a decrease in the dissolution rate. In contrast, the surface-active molecules were dispersed homogeneously throughout the particle matrix in the SA-SD-processed microparticles. Furthermore, improved pharmacokinetic and pharmacodynamic characteristics were observed for the SA-SD-processed fenofibrate microparticles compared to those for the SD-processed fenofibrate particles. Therefore, the SA-SD process incorporating surface-active additives can efficiently micronize poorly water-soluble drugs and optimize their physicochemical and biopharmaceutical characteristics.

Abstract
Micro-/nanoparticle formulations containing drugs with or without various biocompatible excipients are widely used in the pharmaceutical field to improve the physicochemical and clinical properties of the final drug product. Among the various micro-/nanoparticle production technologies, emulsion-based particle formation is the most widely used because of its unique advantages such as uniform generation of spherical small particles and higher encapsulation efficiency (EE). For this emulsion-based micro-/nanoparticle technology, one of the most important factors is the extraction efficiency associated with the fast removal of the organic solvent. In consideration of this, a technology called supercritical fluid extraction of emulsions (SFEE) that uses the unique mass transfer mechanism and solvent power of a supercritical fluid (SCF) has been proposed to overcome the shortcomings of several conventional technologies such as solvent evaporation, extraction, and spray drying. This review article presents the main aspects of SFEE technology for the preparation of micro-/nanoparticles by focusing on its pharmaceutical applications, which have been organized and classified according to several types of drug delivery systems and active pharmaceutical ingredients. It was definitely confirmed that SFEE can be applied in a variety of drugs from water-soluble to poorly water-soluble. In addition, it has advantages such as low organic solvent residual, high EE, desirable release control, better particle size control, and agglomeration prevention through efficient and fast solvent removal compared to conventional micro-/nanoparticle technologies. Therefore, this review will be a good resource for determining the applicability of SFEE to obtain better pharmaceutical quality when researchers in related fields want to select a suitable manufacturing process for preparing desired micro-/nanoparticle drug delivery systems containing their active material.

Abstract
Objectives Lovastatin is an antilipidemic drug that belongs to the class of statins that has poor oral bioavailability due to its low solubility and variable dissolution rate. The main aim of this study was to enhance the solubility and dissolution rate of the drug and understand its oral bioavailability. Materials and Methods Lovastatin nanosuspension was formulated using a solventanti-solvent method using a probe sonication technique. A nanosuspension was prepared, using hydroxypropyl methylcellulose (HPMC) K15M and pluronic F68 as stabilizers. The formulated nanosuspensions were characterized for particle size, polydispersity index (PDI) zeta potential, surface morphology, and in vitro release rate. Further, an in vivo bioavailability study and stability studies were also performed. Results Optimized formulation showed a particle size of 127±0.01 nm, a PDI of 0.492±0.001, and a zeta potential of -37.9 mV, which indicates good stability. Morphological study showed that the particles were in the nano range. The drug content was found to be in the range of 73-87%. In vitro release revealed much faster release of the drug in one hour compared to the pure drug and its marketed formulation. In vivo bioavailability study was carried out in Wistar rats, which showed improvement in bioavailability by approximately 2.5 folds compared with the marketed formulation. Stability studies indicated that the optimized formulation F2 was more stable at 4°C±2°C. Conclusion The prepared lovastatin nanosuspension showed improvement in solubility, dissolution rate, and oral bioavailability compared to the pure drug and its marketed formulation. Hence, lovastatin nanosuspension may be a potentially valuable tool for improving the oral bioavailability of lovastatin.

Abstract
The aim of this work is to present an approach to enhance the dissolution of progestin medication, megestrol acetate (also known as MEGACE), for improving the dissolution rate and kinetic solubility by incorporating nano graphene oxide (nGO). An antisolvent precipitation process was investigated for nGO-drug composite preparation, where prepared composites showed crystalline properties that were similar to the pure drug but enhanced aqueous dispersibility and colloidal stability. To validate the efficient release profile of composite, in vitro dissolution testing was carried out using United States Pharmacopeia, USP-42 paddle method, with gastric pH (1.4) and intestinal pH (6.5) solutions to mimic in vivo conditions. Pure MA is practically insoluble (2 µg/mL at 37 °C). With the incorporation of nGO, it was possible to dissolve nearly 100% in the assay. With the incorporation of 1.0% of nGO, the time required to dissolve 50% and 80% of drug, namely T50 and T80, decreased from 138.0 min to 27.0 min, and the drug did not dissolve for 97.0 min in gastric media, respectively. Additionally, studies done in intestinal media have revealed T50 did not dissolve for 92.0 min. This work shows promise in incorporating functionalized nanoparticles into the crystal lattice of poorly soluble drugs to improve dissolution rate.

Abstract
OBJECTIVE The present work focuses on improving zaleplon (ZAP) performance through nanosizing its insoluble particles which were then delivered intranasally in powder form. SIGNIFICANCE Since nanopowders have an exceptional ability to cross cell membrane, their absorption is facilitated in the solid form. Hence, delivering insoluble ZAP nanocrystals (NC) through intranasal route improves its bioavailability due to both nanosization and the escape of hepatic metabolism. METHODS Nanocrystals were prepared by anti-solvent precipitation followed by probe sonication in presence of Soluplus®, Poloxamer-188 (0.25%), sodium lauryl sulfate (0.5%), and mannitol. Physicochemical evaluation of the prepared NC was done by DSC and XRPD. TGA was performed for stability detection. Ex vivo permeation study through isolated cattle nasal mucosal membrane, in addition to an in vivo bioavailability study was performed for assessment of the prepared NC. RESULTS Nanosization to 200 nm contributed to the enhancement in dissolution ∼100% within 30 min and reduced half-life to 1.63 min. Confirmation of adsorption of polymers over NC' surface was elucidated. TGA confirmed their thermal stability. Ex vivo permeation study showed a 2.7 enhancement ratio in favor of the prepared NC. Both the extent and rate of NC absorption through nasal mucosa of rabbits were significantly higher (p ˂ .05) than in case of oral tablets. The relative bioavailability of NC was increased 3.14 times as compared to the Sleep aid® tablets. CONCLUSION The intranasal delivery of nanoscale ZAP powder proved to be a successful alternative to oral formulations that suffer poor absorption and limited bioavailability.

Abstract
A dual pH- and time-dependent polymeric coated capsule was developed to achieve the site specificity of simvastatin (SIM) release in the colon. To improve the SIM solubility, soluplus-based nanosuspension of the drug were prepared by applying the anti-solvent crystallization technique; this was then followed by lyophilization. Particle size, polydispersity index, and saturation solubility were evaluated. The optimized nanosuspension was combined with SLS and freeze-dried before filling into hard gelatin capsules. Drug release characteristics of the coated capsules were studied in HCl 0.1 N, the phosphate buffers 6.8 and 7.4, and the simulated colonic fluid (pH 6.8). The in-vitro cytotoxic effects of SIM nanoparticles against HT29 cells were then evaluated using the MTT assay. The prepared nanoparticles were spherical with a mean size of 261.66 nm, the zeta potential of -18.20 and the dissolution efficiency of 59.71%. X-ray diffraction and differential scanning calorimetry studies showed that the nanosizing technique transformed the crystalline drug into the more soluble amorphous form. The coated capsules had no release in the gastric media, providing the specific delivery of SIM in the colon. The cytotoxic effect of the SIM nanoparticles was significantly increased, as compared to the free SIM. The findings, therefore, showed that the coated capsules using the two polymers of ethyl cellulose and Eudragit S100 could be suitable for the colon target delivery of SIM.

Abstract
Abstract
Background
The present investigation aimed at preparing nanosuspension of irbesartan to improve its dissolution. Dissolution enhancement of irbesartan can improve the oral bioavailability. Here, it was also studied how media milling time can be reduced by subjecting irbesartan to prior homogenization and then media milling.
Results
First, homogenization of irbesartan was carried out in the presence of poloxamer 407 at 6000 rpm for 2 h. Final nanosuspension preparation was done by media milling with zirconium dioxide beads. Here, the amount of poloxamer 407 and zirconium dioxide beads was studied as statistical independent variables. Response surface plot analysis and desirability function were applied to the selected optimized batch. The prepared batches were subjected to evaluation for zeta potential value, mean particle size, PDI, dissolution study, and stability study. Target particle size was less than 500 nm, and in vitro dissolution in 10 min was more than 80%. Zeta potential value was ~ 27 mV for optimized nanosuspension. Desirability of 0.941 was achieved. Checkpoint batch was prepared and evaluated to confirm the validity of mathematical model. Accelerated stability study was performed on the optimized batch at 40 ± 2 °C/75 ± 5% RH for 6 months.
Conclusion
The results confirmed the stability of formulation at accelerated stability conditions. Using presuspension prepared by homogenization, media milling time primarily reduced from 24–28 h to 18 h. Future perspective is to study other factors in combination method in discrete.

Abstract
Orodispersible films (ODFs) are more convenient for paediatric and geriatric patients to take as compared to conventional tablets and capsules. Electrospinning has recently been attempted to produce ODFs. This study investigated the feasibility of formulating poorly water-soluble drug into ODFs using electrospinning technology coupled with the anti-solvent precipitation method. Piroxicam (PX), a poorly water-soluble drug, was chosen as a model drug. Polyvinyl alcohol and polyvinylpyrrolidone were used as film forming polymers. PX microcrystals were prepared using poloxamer as the stabilizer with the anti-solvent precipitation method, and then loaded in ODFs through the electrospinning process. The obtained ODFs were characterized using a scanning electron microscope, X-ray powder diffraction and Fourier transform infrared spectroscopy with respect to the morphology, solid state and potential molecular interaction between the model drug and polymers. The mechanical property, disintegration and dissolution rate of the obtained ODF were evaluated using dynamic mechanical analysis, a customized method and USP2 apparatus. The results showed that PX microcrystals suspended in polymeric solutions could be readily electrospun into fibrous films, where the microcrystals scattered between the fibers. The electrospun fibrous film-based ODFs exhibited satisfactory mechanical behaviour, and fast disintegration upon the polymer selection. In the dissolution tests, almost 90% of PX was dissolved within 6 min from the ODFs, whereas 40% of PX dissolved from physical mixtures in 60 min. This study demonstrated that poorly water-soluble drugs could be formulated into ODFs with satisfactory quality attributes by combining micronization and the electrospinning process.

Abstract
Cocrystals are homogenous (single-phase) crystalline structures composed by two or more components in a definite stoichiometric ratio bonded together by noncovalent bonds. Pharmaceutical industry has been showing interest in cocrystals due to their ability to improve active pharmaceutical ingredients (API's) properties, such as solubility, dissolution, bioavailability, stability and processability. The necessity for high-throughput screening methods and methods capable of producing cocrystals in an industrial scale still hinders the use of cocrystals by the pharmaceutical industry. The aim of this review is to present an extensive overview of the cocrystallization methods, focusing in the specificities of each technique, its advantages and disadvantages. The review is divided into solvent-based and solvent-free methods. The most appropriate methods to the different stages of cocrystals manufacture, from the screening phase to industrial production are identified. The use of continuous and scalable methods in cocrystal production as well as the implementation of quality-by-design and process analytical technology concepts are also addressed.

Abstract
Development of techniques to enhance bioavailability of drugs having poor water solubility is a big challenge for pharmaceutical industry. Solubility can be enhanced by particle size reduction and encapsulation using hydrophilic polymers. Fenofibrate (FF) is a drug for regulating lipids. Multi-fold enhancement in solubility of FF has been achieved by nanocrystal formation in the present study. Nanoparticles were prepared by an evaporation-assisted solvent-antisolvent interaction (EASAI) approach. Water-soluble polymers, viz. polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA), and hydroxypropyl methylcellulose (HPMC), were used to encapsulate and thus control the particle size of FF nanocrystals. Spherical particles having average particle size well below 30 nm could be prepared under optimum conditions. Almost complete release of the drug molecules from the polymer-stabilized nanocrystals within 2 h was clearly evident from the in vitro drug release studies. Infrared (FTIR) spectroscopy indicated the absence of solvent impurities and any strong interaction between the drug and stabilizers. The polymorphic form of raw-FF was retained in the nanoparticles as per the X-ray diffraction (XRD) patterns. Lower crystallinity of the nanoformulated samples compared to raw-FF was confirmed by differential scanning calorimetric (DSC) studies.

Abstract
Microcrystals of piroxicam (PRX) monohydrate with a narrow size distribution were prepared from acetone/PRX solutions by antisolvent crystallization via metallic membranes with ordered pore arrays. Crystallization was achieved by controlled addition of the feed solution through the membrane pores into a well-stirred antisolvent. A complete transformation of an anhydrous form I into a monohydrate form of PRX was confirmed by Raman spectroscopy and differential scanning calorimetry. The size of the crystals was 7-34 μm and was controlled by the PRX concentration in the feed solution (15-25 g L-1), antisolvent/solvent volume ratio (5-30), and type of antisolvent (Milli-Q water or 0.1-0.5 wt % aqueous solutions of hydroxypropyl methyl cellulose (HPMC), poly(vinyl alcohol) or Pluronic P-123). The smallest crystals were obtained by injecting 25 g L-1 PRX solution through a stainless-steel membrane with a pore size of 10 μm into a 0.06 wt % HPMC solution stirred at 1500 rpm using an antisolvent/solvent ratio of 20. HPMC provided better steric stabilization of microcrystals against agglomeration than poly(vinyl alcohol) and Pluronic P-123, due to hydrogen bonding interactions with PRX and water. A continuous production of large PRX monohydrate microcrystals with a volume-weighted mean diameter above 75 μm was achieved in a continuous stirred membrane crystallizer. Rapid pouring of Milli-Q water into the feed solution resulted in a mixture of highly polydispersed prism-shaped and needle-shaped crystals.

Abstract
Efavirenz is a fundamental drug in the HIV therapy; however, it has a low bioavailability due to low water solubility. Particle nanonization should enhance its dissolution and therefore its bioavailability. Nanocrystallization is a promising technique for preparing drug nanocrystals. A solution containing efavirenz (EFV) and methanol was added to an aqueous solution of particle stabilizers, under sonication. The adequate polymer stabilizer and its concentration and drug load were evaluated. Particle size and zeta potential of suspensions were measured. Nanosuspensions were freeze-dried and the resulting powder was characterized by some techniques, with special attention to dissolution. Particle size and zeta potential analysis showed that HMPC and PVP were the most suitable polymers. All samples prepared with these stabilizers had nanosized particles and proper zeta potential; however, sedimentation and particle growth were detected with Turbiscan™. Time-related destabilization occurred when the lowest polymer concentration of 20% was used. SEM analysis of the dried powder shows film formation for suspensions with 40% of polymer and particle aggregation in samples with less polymer. Dissolution profiles of samples were higher than EFV raw material, although the lower the polymer concentration, the higher the dissolution.

Abstract
Oral drug absorption is a process influenced by the physicochemical and biopharmaceutical properties of the drug and its inter-relationship with the gastrointestinal tract. Drug solubility, dissolution and permeability across intestinal barrier are the key parameters controlling absorption. This review provides an overview of the factors that affect drug absorption and the classification of a drug on the basis of solubility and permeability. The biopharmaceutical classification system (BCS) was introduced in early 90׳s and is a regulatory tool used to predict bioavailability problems associated with a new entity, thereby helping in the development of a drug product. Strategies to combat solubility and permeability issues are also discussed.

Abstract
In the present study, solid dispersion nanoparticles with a hydrophilic polymer and surfactant were developed using the supercritical antisolvent (SAS) process to improve the dissolution and oral absorption of megestrol acetate. The physicochemical properties of the megestrol acetate solid dispersion nanoparticles were characterized using scanning electron microscopy, differential scanning calorimetry, powder X-ray diffraction, and a particle-size analyzer. The dissolution and oral bioavailability of the nanoparticles were also evaluated in rats. The mean particle size of all solid dispersion nanoparticles that were prepared was <500 nm. Powder X-ray diffraction and differential scanning calorimetry measurements showed that megestrol acetate was present in an amorphous or molecular dispersion state within the solid dispersion nanoparticles. Hydroxypropylmethyl cellulose (HPMC) solid dispersion nanoparticles significantly increased the maximum dissolution when compared with polyvinylpyrrolidone K30 solid dispersion nanoparticles. The extent and rate of dissolution of megestrol acetate increased after the addition of a surfactant into the HPMC solid dispersion nanoparticles. The most effective surfactant was Ryoto sugar ester L1695, followed by D-α-tocopheryl polyethylene glycol 1000 succinate. In this study, the solid dispersion nanoparticles with a drug:HPMC:Ryoto sugar ester L1695 ratio of 1:2:1 showed >95% rapid dissolution within 30 minutes, in addition to good oral bioavailability, with approximately 4.0- and 5.5-fold higher area under the curve (0–24 hours) and maximum concentration, respectively, than raw megestrol acetate powder. These results suggest that the preparation of megestrol acetate solid dispersion nanoparticles using the supercritical antisolvent process is a promising approach to improve the dissolution and absorption properties of megestrol acetate.

Abstract
Akebia Saponin D (ASD) or asperosaponin VI is the most abundant constituent of the rhizome of Dipsacus asper, which has been used for the treatment of lower back pain, traumatic hematoma and bone fractures. In recent years, it was reported that ASD was a potential treatment strategy for Alzheimer's disease (AD). However, the low bioavailability of ASD limited its clinical utility. Microcrystalline preparation is one of the effective methods to improve drug absorption. The drugs prepared by different methods can present different solid forms (polymorphs), and different polymorphs have significantly different bioavailabilities. The objective of this study was to prepare ASD polymorphs using the different preparation processes and to evaluate their physicochemical properties and oral absorption. ASD-2 obtained by the antisolvent process was simpler and had higher recovery (78.5%) than that of ASD-1 by a two-step macroporous resin column separation (56.5%). The ASD polymorphs were characterized using differential scanning calorimetry (DSC), thermogravimetry analysis (TGA), powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM). The results revealed that ASD-2 existed in microcrystalline form, while ASD-1 was amorphous. Furthermore, the equilibrium solubility, dissolution in aqueous solution and pharmacokinetic parameters of the samples were determined. ASD-2 showed lower aqueous solubility than that of ASD-1 (p < 0.01). In addition, ASD-2 showed lower dissolution with only 65% of the drug released while ASD-1 had a higher dissolution with 99% of drug released at the end of the 180 min testing period. Although ASD-1 significantly increased solubility and dissolution, the AUC 0-20h of ASD-2 was 4.3 times that of the amorphous ASD-1 in vivo. Data suggest that the microcrystalline preparation of ASD-2 is not only reasonable in economy and suitable for large-scale preparation, but also a promising method to enhance bioavailability of ASD.

Abstract
This study concerns a new compound named CRS 74 which has the property of inhibiting Human Immunodeficiency Virus (HIV) protease, an essential enzyme involved in HIV replication process. It is proved in this study that the original CRS 74 exhibits poor aqueous solubility and a very low dissolution rate, which can influence its bioavailability and clinical response. In an attempt to improve the dissolution rate, CRS 74 was recrystallized by liquid anti-solvent (LAS) crystallization. Ethanol was chosen as solvent and water as the anti-solvent. Recrystallized solids were compared with the original drug crystals in terms of physical and dissolution properties. Recrystallization without additives did not modify the CRS 74 dissolution profile compared to the original drug. CRS 74 was then recrystallized using different additives to optimize the process and formulate physicochemical properties. Steric stabilizer in organic phase ensured size-controlling effect, whereas electrostatic stabilizer in aqueous phase decreased particle agglomeration. Cationic additives avoided drug adsorption onto stainless steel T-mixer. In general, additive improved drug dissolution rate due to improvement of wetting properties by specific interactions between the drug and the additives, and ensured continuous production of CRS 74 by electrostatic repulsion.

Mesoporous carbon with spherical pores as a carrier for celecoxib with needle-like crystallinity: improve dissolution rate and bioavailability. MATERIALS SCIENCE & ENGINEERING.

Abstract
The purposes of this investigation are to design mesoporous carbon (MC) with spherical pore channels and incorporate CEL to it for changing its needlelike crystal form and improving its dissolution and bioavailability. A series of solid-state characterization methods, such as SEM, TEM, DSC and XRD, were employed to systematically investigate the existing status of celecoxib (CEL) within the pore channels of MC. The pore size, pore volume and surface area of samples were characterized by nitrogen physical absorption. Gastric mucosa irritation test was carried out to evaluate the safety of mesoporous carbon as a drug carrier. Dissolution tests and in vivo pharmacokinetic studies were conducted to confirm the improvement in drug dissolution kinetics and oral bioavailability. Uptake experiments were conducted to investigate the mechanism of the improved oral bioavailability. The results of solid state characterization showed that MC was prepared successfully and CEL was incorporated into the mesoporous channels of the MC. The crystallinity of CEL in MC was affected by different loading methods, which involve evaporation method and melting method. The dissolution rate of CEL from MC was found to be significantly higher than that of pure CEL, which attributed to reduced crystallinity of CEL. The gastric mucosa irritation test indicated that the MC caused no harm to the stomach and produced a protective effect on the gastric mucosa. Uptake experiments indicated that MC enhanced the amount of CEL absorbed by Caco-2 cells. Moreover, oral bioavailability of CEL loaded within the MC was approximately 1.59-fold greater than that of commercial CEL. In conclusion, MC was a safe carrier to load water insoluble drug by controlling the crystallinity or crystal form with improvement in drug dissolution kinetics and oral bioavailability.

Abstract
We prepared amphotericin B (AmB) nanoparticles through liquid antisolvent precipitation (LAP) and by freeze-drying to improve the solubility of AmB for oral administration. The LAP was optimized through a single-factor experiment. We determined the effects of surfactants and their concentration, the stirring time, the precipitation temperature, the stirring intensity, the drug concentration and the volume ratio of antisolvent to solvent on the mean particle size (MPS) of the AmB nanoparticles. Increased stirring intensity and precipitation time favored AmB nanoparticles with smaller MPS, but precipitation times exceeding 30 min did not further reduce the MPS. Increased Tween-80 concentration and the drug concentration decreased the MPS of the AmB nanoparticles. Increased precipitation temperature and antisolvent to solvent volume ratio initially decreased the MPS of the AmB nanoparticles, which increased thereafter. Optimum conditions produced AmB nanoparticles with an MPS of 135.1 nm. The AmB nanoparticles were characterized through scanning electron microscopy (SEM), mass spectrometry (MS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermal gravimetric analysis (TG), solvent residue, drug purity test, and dissolution testing. The analyses indicated that the chemical structure of AmB remained unchanged in the nanoparticles, but the structure was changed from crystalline to amorphous. The residual DMSO in the nanoparticles was 0.24% less than the standard set by the International Conference on Harmonization limit for class III solvents. The AmB nanoparticles exhibited 2.1 times faster dissolution rates and 13 times equilibrium solubility compared with the raw drug. The detection results indicate that the AmB nanoparticles potentially improved the oral absorption of AmB.

Docetaxel-nicotinamide complex-loaded nanostructured lipid carriers for transdermal delivery. Int J Pharm 2013; 458:296-304.

Abstract
Docetaxel (DTX) proved one of the most effective active pharmaceutical ingredients (APIs) for the treatment of cancers. However, in respect of its low solubility and high lipophilic property, nicotinamide (NCT) was chosen as the co-former to form the docetaxel-nicotinamide complex to handle the drawbacks. As was analyzed by Fourier Transform Infrared spectrometer, thermal analysis and saturated solubility, the complex proved stable. Then, docetaxel-nicotinamide complex nanostructured lipid carriers (DN-NLCs) were prepared by emulsion-evaporation at low temperature method. The average drug entrapment efficiency, particle size and drug loading of docetaxel-NLCs (D-NLCs) and DN-NLCs were 81.41-79.48%, 61.45-59.48nm and 1.60-1.63%, respectively. The physicochemical characteristics of nanoparticles were valued by transmission electron microscope and Powder X Ray Diffraction. The in vitro drug-release profile of nanoparticle formulations fitted the Weibull dynamic equation. The skin permeability test was performed by Vertical Franz-type diffusion cells. It demonstrated that DN-NLCs transported drugs more easily than D-NLCs. Confocal Laser Scanning Microscopy observation showed DN-NLCs permeated more effectively than D-NLCs. In vivo study demonstrated that DN-NLCs maintained most in the skin. These results suggest that the DN-NLCs can be a useful method to increase skin permeation of docetaxel.
