Synthesized nano particles of glimepiride via spray freezing into cryogenic liquid: characterization, antidiabetic activity, and bioavailability. Drug Deliv 2022; 29:364-373. [PMID: 35068278 PMCID: PMC8788345 DOI: 10.1080/10717544.2021.2018524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 12/02/2021] [Accepted: 12/06/2021] [Indexed: 11/20/2022] Open
Abstract
The aim of this work was to formulate glimepiride (class II drug) which is characterized by low solubility and high permeability as nanostructured particles using a cryogenic technique with an aid of water-soluble polymer to improve its aqueous solubility and hence its bioavailability. 27 formula of glimepiride nano size particles were prepared by a spray freezing into cryogenic liquid (SCFL) using poly vinyl pyrrolidone K-30 (PVP K-30); that three drug polymer ratio (1:1, 1:2, and 1:3), with three different volumes of feeding solution (50, 100, 150 mL), at three flow rates (10, 20, and 30 mL/min). The prepared formulations were evaluated for production yield, particle size, zeta potential, drug content, release rate, in vivo hypoglycemic activity, and bioavailability. All prepared formulations showed high production yield and drug content ranged between 91.1 ± 3.4% and 94.3 ± 1.8% and 95.1 ± 2.8% and 97.1 ± 2.5%, respectively. The mean particles size was ranged between 280 ± 62 nm and 520 ± 30 nm. The results of in vitro release study revealed significant enhancement in the solubility of prepared formulations compared with the pure drug. It was found that optimal formula showed a significant reduction in blood glucose levels in diabetic rats, and 1.79-fold enhancements in oral bioavailability compared with market tablets. Nanoparticle prepared by SCFL method is an encouraging formula for improving the solubility and the bioavailability of glimepiride.

Abstract
Biological macromolecules, especially therapeutic proteins, are delicate and highly sensitive to denaturation from stresses encountered during the manufacture of dosage forms. Thin-film freeze-drying (TFFD) and spray freeze-drying (SFD) are two processes used to convert liquid forms of protein into dry powders. In the production of inhalable dry powders that contain proteins, these potential stressors fall into three categories based on their occurrence during the primary steps of the process: (1) droplet formation (e.g., the mechanism of droplet formation, including spray atomization), (2) freezing, and (3) frozen water removal (e.g., sublimation). This study compares the droplet formation mechanism used in TFFD and SFD by investigating the effects of spraying on the stability of proteins, using lactoferrin as a model. This study considers various perspectives on the denaturation (e.g., conformation) of lactoferrin after subjecting the protein solution to the atomization process using a pneumatic two-fluid nozzle (employed in SFD) or a low-shear drop application through the nozzle. The surface activity of lactoferrin was examined to explore the interfacial adsorption tendency, diffusion, and denaturation process. Subsequently, this study also investigates the secondary and tertiary structure of lactoferrin and the quantification of monomers, oligomers, and, ultimately, aggregates. The spraying process affected the tertiary structure more negatively than the tightly woven secondary structure, resulting in the peak position corresponding to the tryptophan (Trp) residues red-shifting by 1.5 nm. This conformational change can either (a) be reversed at low concentrations via relaxation or (b) proceed to form irreversible aggregates at higher concentrations. Interestingly, when the sample was allowed to progress into micrometer-sized aggregates, such a dramatic change was not detected using methods such as size-exclusion chromatography, polyacrylamide gel electrophoresis, and dynamic light scattering at 173°. A more complete understanding of the heterogeneous protein sample was achieved only through a combination of 173 and 13° backward and forward scattering, a combination of derived count rate measurements, and microflow imaging (MFI). After studying the impact of droplet formation mechanisms on aggregation tendency of lactoferrin, we further investigated two additional model proteins with different surface activity: bovine IgG (serving as a non surface-active negative reference), and β-galactosidase (another surface-active protein). The results corroborated the lactoferrin findings that spray-atomization-related stress-induced protein aggregation was much more pronounced for proteins that are surface active (lactoferrin and β-galactosidase), but it was minimal for non-surface-active protein (bovine IgG). Finally, compared to the low-shear dripping used in the TFFD process, lactoferrin underwent a relatively fast conformational change upon exposure to the high air-water interface of the two-fluid atomization nozzle used in the SFD process as compared to the low shear dripping used in the TFFD process. The interfacial-induced denaturation that occurred during spraying was governed primarily by the size of the atomized droplets, regardless of the duration of exposure to air. The percentage of denatured protein population and associated activity loss, in the case of β-galactosidase, was determined to range from 2 to 10% depending on the air-flow rate of the spraying process.

Abstract
The oral route is the most preferred delivery route for drug administration due to its advantages such as lower cost, improved patient compliance, no need for trained personnel and the drug reactions are generally less severe. The major problem with new molecules in the drug discovery pipeline is poor solubility and dissolution rate that ultimately results in low oral bioavailability. Numerous techniques are available for solubility and bioavailability (BA) enhancement, but out of all, solid dispersion (SD) is proven to be the most feasible due to the least issues in manufacturing, processing, storage, and transportation. In the past few years, SD had been extensively applied to reinforce the common issues of insoluble drugs. Currently, many hydrophobic and hydrophilic polymers are used to prepare either immediate release or controlled release SDs. Therefore, the biological behavior of the SDs is contingent upon the use of appropriate polymeric carriers and methods of preparation. The exploration of novel carriers and methodologies in SD technology leads to improved BA and therapeutic effectiveness. Moreover, the clinical applicability of SD-based formulations has been increased with the discovery of novel polymeric carriers. In this review, emphasis is laid down on the present status of recent generations of SDs (i.e., surfactant and controlled release polymer-based SD) and their application in modifying the physical properties of the drug and modulation of pharmacological response in different ailments.

Abstract
High porous particles with specific aerodynamic properties were processed by the spray freeze-drying (SFD) method. Comprehensive knowledge about all aspects of the SFD method is required for particle engineering of various pharmaceutical products with good flow properties. In this review, different types of the SFD method, the most frequently employed excipients, properties of particles prepared by this method, and most recent approaches concerning SFD are summarized. Generally, this technique can prepare spherical-shaped particles with a highly porous interior structure, responsible for the very low density of powders. Increasing the solubility of spray freeze-dried formulations achieves the desired efficacy. Also, due to the high efficiency of SFD, by determining the different features of this method and optimizing the process by model-based studies, desirable results for various inhaled products can be achieved and significant progress can be made in the field of pulmonary drug delivery.

Abstract
Amorphous solid dispersions (ASDs) are popular for enhancing the solubility and bioavailability of poorly water-soluble drugs. Various approaches have been employed to produce ASDs and novel techniques are emerging. This review provides an updated overview of manufacturing techniques for preparing ASDs. As physical stability is a critical quality attribute for ASD, the impact of formulation, equipment, and process variables, together with the downstream processing on physical stability of ASDs have been discussed. Selection strategies are proposed to identify suitable manufacturing methods, which may aid in the development of ASDs with satisfactory physical stability.

Abstract
Freeze-drying, also known as lyophilization, is a process in which water in the form of ice under low pressure is removed from a material by sublimation. This process has found many applications for the production of high quality food and pharmaceuticals. The main steps of the freeze-drying process, such as the freezing of the product and primary and secondary drying, are described in this paper. The problems and mechanisms of each step of the freeze-drying process are also analyzed. The methods necessary for the selection of the primary and secondary end processes are characterized. The review contains a description of the effects of process conditions and the selected physical properties of freeze-dried materials, such as structural properties (shrinkage and density porosity), color, and texture. The study shows that little attention is given to the mechanical properties and texture of freeze-dried materials obtained from different conditions of the lyophilization process.

Abstract
Pharmaceutical manufacturing is evolving from traditional batch processes to continuous ones. The new global competition focused on throughput and quality of drug products is certainly the driving force behind this transition which, thus, represents the new challenge of pharmaceutical manufacturing and hence of lyophilization as a downstream operation. In this direction, the present review deals with the most recent technologies, based on spray freeze-drying, that can achieve this objective. It provides a comprehensive overview of the physics behind this process and of the most recent equipment design.

Abstract
Natural products are an important source of therapeutically effective compounds throughout the world. Since ancient times, a huge amount of both plant extracts and isolated compounds have been largely employed in treatment and prevention of human disorders and, currently, more than 60% of the world's population trusts on plant medicaments as demonstrated by the increasing quantity of herbal therapeutics in the market. Unfortunately, several promising natural molecules for the treatment of the most diverse ailments are characterized by extremely unfavourable features, such as low water solubility and poor/irregular bioavailability, which hinder their clinical use. To overcome these limitations and to make herbal therapy more effective, different formulative approaches have been employed. Among the different strategies for increasing drug solubility, nanocrystals can be considered one of the most interesting and successful approaches. Drug nanocrystals are nanosized drug particles usually formulated as nanosuspensions, namely submicron dispersions in liquid media where surfactants, polymers, or a mixture of both act as stabilisers. In this review, we described the most significant results and progresses concerning drug nanocrystal formulations for the delivery of natural compounds with a significant pharmacological activity. The text is organized in nine sections, each focusing on a specific poorly water- soluble natural compound (apigenin, quercetin, rutin, curcumin, baicalin and baicalein, hesperetin and hesperidin, resveratrol, lutein, silybin). To foster the clinical translation of these natural nanomedicines, our opinion is that future research should pair the essential pharmacokinetic studies with carefully designed pre-clinical experiments, able to prove the formulation efficacy in relevant animal models in vivo.

Abstract
In this study, mesoporous SnO2 (MSn) with a three-dimensional mesoporous structure was prepared using MCM-48 as the template in order to increase the oral bioavailability and dissolution rate of insoluble drugs. The model drug, nitrendipine (NDP), was loaded into the MSn by the adsorption method. The structural features of MSn were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and N2 adsorption (desorption) analysis. NDP was existed in the pore channels of MSn in an amorphous state, which was characterized by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), and Fourier transform infrared spectroscopy (FTIR). MSn showed a good biocompatibility in the cell toxicity assay for Caco-2 cells. In vitro dissolution results suggested that MSn could significantly enhance the dissolution rate of NDP compared with commercial NDP tablets. Pharmacokinetic studies indicated that NDP-MSn tablets effectively enhanced the oral bioavailability of NDP. In conclusion, MSn was found to be a potential carrier for improving the solubility of insoluble drugs.

The downsizing processes are done using a top-down approach (milling and homogenization currently employed at the industrial level), while the crystallization process is performed by bottom-up techniques (e.g., antisolvent precipitation, use of supercritical fluids or spray and freeze drying). In addition, the production of nanocrystals in confined environment can be achieved within microfluidics channels. This review analyzes the processes for the preparation of nanocrystals and co-crystals, divided by top-down and bottom-up approaches, together with their combinations. The combination of both strategies merges the favorable features of each process and avoids the disadvantages of single processes. Overall, the applicability of drug nanocrystals is highlighted by the widespread research on the production processes at the engineering, pharmaceutical, and nanotechnology level.

Abstract
OBJECTIVES Solid dispersion formulations have attracted attention to improve solubility and bioavailability of water-insoluble drugs. In this study, the variation of solubility and bioavailability by different preparation methods were studied using itraconazole (ITZ) solid dispersions. METHODS Itraconazole solid dispersions were prepared by a solvent-controlled precipitation method (SCPM) using HPMCAS-LF, HCl antisolvent or a spray-drying method (SDM) for comparison. Dissolution tests by pH transition and pharmacokinetic study using male Sprague Dawley rats were conducted. KEY FINDINGS Itraconazole solid dispersion dissolution tests by pH transition exhibited better dissolution compared to naive ITZ, limited dissolution in acidic conditions and a burst release at neutral pH. The ITZ solid dispersions by SCPM indicated a smaller-sized particle dispersion, limited dissolution at acidic pH and a higher release at neutral pH compared to those by SDM, suggesting that the increased protonation of anionic polymers and HPMCAS-LF by acidic antisolvent could form a tighter hydrophobic aggregation with ITZ in solid dispersions. ITZ solid dispersion prepared by SCPM also showed improved ITZ absorption in male Sprague Dawley rats compared to SDM and naïve ITZ. CONCLUSIONS This study suggests that the SCPM method can be widely used for solid dispersion preparations due to improved dissolution and PK profile.

Abstract
In spray freeze-srying (SFD), a solution is sprayed into a refrigerant medium, frozen, and subsequently sublimation dried, which allows the production of flowable lyophilized powders. SFD allows commonly freeze-dried active pharmaceutical ingredients (e.g., proteins and peptides) to be delivered using new applications such as needle-free injection and nasal or pulmonary drug delivery. In this study, a droplet stream was injected into a vortex of cold gas in order to reduce the risk of droplet collisions and therefore droplet growth before congelation, which adversely affects the particle size distribution. Droplets with initial diameters of about 40-50 μm were frozen quickly in a swirl tube at temperatures around -75°C and volumetric gas flow rates between 17 and 34 L/min. Preliminary studies that were focused on the evaluation of spray cone footprints were performed prior to SFD. A 23 factorial design with a model solution of mannitol (1.5% m/V) and maltodextrin (1.5% m/V) was used to create flowable, low density (0.01-0.03 g/cm3) spherical lyophilisate powders. Mean particle diameter sizes of the highly porous particles ranged between 49.8 ± 6.6 and 88.3 ± 5.5 μm. Under optimal conditions, the mean particle size was reduced from 160 to 50 μm (decrease of volume by 96%) compared to non-expanded streams, whereas the SPAN value did not change significantly. This method is suitable for the production of lyophilized powders with small particle sizes and narrow particle size distributions, which is highly interesting for needle-free injection or nasal delivery of proteins and peptides.

Abstract
The aim of this study was to investigate a fixed dose combination (FDC) of telmisartan (TEL) and pravastatin sodium (PRA) in enteric-coated bilayer tablets, which was designed for once-daily bedtime dose in order to match circadian rhythmic variations of hypertension and cholesterol synthesis and optimize the patient friendly dosing treatment. Due to the poor aqueous solubility of TEL, ternary solid dispersions (SD) consisting of TEL, polyethylene glycol 6000 (PEG 6000) and magnesium oxide (MgO) were designed to enhance its dissolution rate in intestinal fluid. MgO was added as an effective alkalizer to maintain the high microenvironmental pH of the saturated solution in the immediate vicinity of TEL particles because TEL is known to be ionizable but poorly soluble in intestinal fluid. In contrast, PRA is known to be very unstable in low pH conditions. In the SD system, TEL was present in an amorphous structure and formed an intermolecular hydrogen bonding with MgO, giving complete drug release without precipitation in intestinal fluid. In addition, the amount of hydrophilic carrier (PEG 6000) was also a factor. In the design of tablet formulation, the diluents and superdisintegrants could play a key role in release profiles. Then, to fulfill the unmet needs of the two model drugs and match circadian rhythmic variations of hypertension and cholesterol synthesis, enteric-coated bilayer tablet consisting of TEL SD and PRA was finally prepared using Acryl-EZE® as an enteric coating material. Prior to enteric coating, a seal coating layer (Opadry®, 2% weight gains) was firstly introduced to separate the core bilayer tablet from the acidic enteric coating polymers to avoid premature degradation. Dissolution profiles of finished tablets revealed that enteric-coated bilayer tablets with 6% weight gains remained intact in acidic media (pH 1.0) for 2h and then released drugs completely within 45min after switching to the intestinal media (pH 6.8). It was observed that enteric-coated bilayer tablets were stable during 3 month under the accelerated condition of 40°C/75% RH. The delayed drug release and bedtime dosage regimen using enteric-coated bilayer tablet containing TEL and PRA, matching the circadian rhythms of hypertension and hyperlipidemia can provide therapeutic benefits for elderly patients in terms of maximizing the therapeutic effects.

Abstract
Purpose: The objective of this study was to develop, characterize, and comparatively investigate the ketotifen fumarate (KF) nanosuspensions (NSS) to enhance the permeability of KF. Methods: In the present work, the NSP and NSE were prepared by double-emulsion solvent evaporation/nanoprecipitation methods with poly (D,Llactide-co-glycolide) and Eudragit RL100 polymers, respectively. The loading efficiency, particle size, and polydispersity index of prepared different NSs were evaluated with scanning electron microscopy (SEM), X-ray diffraction, differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), and in vitro release and transcorneal permeation . NSs were also compared on the basis of particle size and polydispersity index. Results: Particle size, polydispersity index, and loading efficiency of NSP1 and NSE3 showed the best value (158 nm, 117 nm, 0.21, 0.43 and 43%, 95.23%, respectively). SEM showed spherical globules and DSC results showed the reduction in crystallinity. The NSE3 formulations demonstrated significantly (p<0.05) higher drug release rates than the NSP1 due to increases in the surface area. Comparative studies showed that NSE release and permeability are higher than NSP. Conclusion: It is concluded that both NSP and NSE provide a useful dosage form for the ocular drug delivery which can enhance the permeability of KF.

Abstract
Nanocrystals are pure drug crystals with sizes in the nanometer range. Due to the advantages of high drug loading, platform stability, and ease of scaling-up, nanocrystals have been widely used to deliver poorly water-soluble drugs. Nanocrystals in the blood stream can be recognized and sequestered as exogenous materials by mononuclear phagocytic system (MPS) cells, leading to passive accumulation in MPS-rich organs, such as liver, spleen and lung. Particle size, morphology and surface modification affect the biodistribution of nanocrystals. Ligand conjugation and stimuli-responsive polymers can also be used to target nanocrystals to specific pathogenic sites. In this review, the progress on injected nanocrystals for targeted drug delivery is discussed following a brief introduction to nanocrystal preparation methods, i.e., top-down and bottom-up technologies.

Abstract
Chitosan and alginate nano-composite (NP) carriers intended for colonic delivery containing prednisolone and inulin were obtained by two processes. Spray freeze-drying using chitosan (SFDC) or alginate (SFDA) was proposed as an alternative to the traditional chitosan-tripolyphosphate platform (CTPP). NPs were fully characterised and assessed for their yield of particles; level of prednisolone and inulin release in phosphate and Krebs buffers; and sensitivity to degradation by lysozyme, bacteria and faecal slurry. NPs based on chitosan showed similar properties (size, structure, viscoelastic behaviour), but those based on SFDC showed a higher mean release of both active ingredients, with similar efficiency of encapsulation and loading capacity for prednisolone but lower for inulin. SFDC was less degraded in the presence of lysozyme and E. coli and was degraded by B. thetaiotaomicron but not by faecal slurry. The results obtained with SFDA were promising because this NP showed good encapsulation parameters for both active ingredients and biological degradability by E. coli and faecal slurry. However, it will be necessary to use alginate derivatives to reduce its solubility and improve its mechanical behaviour.

Abstract
A system that can deliver drug at a controlled rate is very important for the treatment of various chronic diseases such as diabetes, asthma, and heart disease. Poorly water-soluble drug with pH-dependent solubility such as gliclazide (GLZ) offers challenges in the controlled-release formulation because of low dissolution rate and poor bioavailability. Solid dispersion (SD) of GLZ consisted of hydroxypropyl cellulose (HPC-SSL) as a polymeric solubilizer was manufactured by hot melt extrusion (HME) technology. Then, controlled porosity osmotic pump (CPOP) tablet of gliclazide was designed to deliver drug in a controlled manner up to 16 h. The developed formulation was optimized for type and level of pore former and coating weight gain. The optimized formulation was found to exhibit zero order kinetics independent of pH and agitation speed but depends on osmotic pressure of dissolution media indicated that mechanism of drug release was osmotic pressure. The in vivo performance prediction of developed formulation using convolution approach revealed that the developed formulation was superior to the existing marketed extended-release formulation in terms of attaining steady state plasma levels and indicated adequate exposure in translating hypoglycemic response. The prototype solubilization method combined with controlled porosity osmotic pump based technique could provide a unique way to increase dissolution rate and bioavailability of many poorly water-soluble, narrow therapeutic index drugs used in diabetes, cardiovascular diseases, etc.

Abstract
Aim of present work was to originally elucidate the roles of ultrasonication method for modulating the size and molecular interactions in controlling release of poorly water-soluble drug. Curcumin was chosen as a model drug. Three types of polymers were investigated as carriers for preparation of polymeric nanoparticles under various ultrasonication conditions and polymer-drug ratios. Changes in drug crystallinity, particle size, and molecular interactions which would be factors enhancing drug dissolution rate were evaluated. Amorphous form of curcumin, size reduction of nanoparticles and interaction between drug and polymer in formulations were attributed to improved drug dissolution rate. Particle size was strongly affected by polymer type, polymer-drug ratio and ultrasonication conditions. Interestingly, control of those factors caused differences in molecular interactions of the hydroxyl groups and then, highly affected particle size of the nanoparticles. It was obvious that there was a reciprocal influence between the drug-polymer interactions and particle size of the nanoparticles. This relation could be modulated by polymers and ultrasonication processes for enhancing drug dissolution rate.

Abstract
Nanosizing is one of the most important drug delivery platform approaches for the commercial development of poorly soluble drug molecules. The research efforts of many industrial and academic groups have resulted in various particle size reduction techniques. From an industrial point of view, the two most advanced top-down processes used at the commercial scale are wet ball milling and high pressure homogenization. Initial issues such as abrasion, long milling times and other downstream-processing challenges have been solved. With the better understanding of the biopharmaceutical aspects of poorly water-soluble drugs, the in vivo success rate for drug nanocrystals has become more apparent. The clinical effectiveness of nanocrystals is proven by the fact that there are currently six FDA approved nanocrystal products on the market. Alternative approaches such as bottom-up processes or combination technologies have also gained considerable interest. Due to the versatility of nanosizing technology at the milligram scale up to production scale, nanosuspensions are currently used at all stages of commercial drug development, Today, all major pharmaceutical companies have realized the potential of drug nanocrystals and included this universal formulation approach into their decision trees.

Abstract
For the quality evaluation of raw materials, the influence of various types of solvents on the polymorphic crystallization behaviors and dissolution rates of two sources of valsartan (VAL) from China and India was investigated. Samples were prepared by recrystallization from water or organic solvents, such as acetonitrile, acetone and ethanol, using methods with and without heating. Recrystallization behaviors were characterized by differential scanning calorimetry (DSC) and powder X-ray diffraction (PXRD). Scanning electron microscopy (SEM) was also used to observe the morphology of samples. The dissolution rate of recrystallized samples in water was evaluated and compared to the original VAL sample. There were significant differences in morphology, crystal structure and dissolution rate among the samples recrystallized using organic solvents. VAL was transformed into another polymorphic form by the solvents and recrystallization conditions. These physical properties of VAL also differed between the two sources of VAL. Thus, the physicochemical differences of raw materials should be carefully considered in early dosage formulation approaches.

Abstract
CONTEXT Along with other options, solid dispersions prepared by spray drying offer the possibility of formulating poorly soluble drugs in a rapidly dissolving format. As a wide range of potential excipients and solvents is available for spray drying, it is usually necessary to carry out a comprehensive array of studies to arrive at an optimal formulation. OBJECTIVE To study the influence of formulation parameters such as co-sprayed excipients, solvents and packaging on the manufacture, in vitro performance and stability of spray-dried oral drug products using fenofibrate as a model drug. MATERIALS AND METHODS Solid dispersions of fenofibrate with different amorphous polymers were manufactured from two solvent systems by spray drying. These were characterized in terms of physicochemical properties, crystalline content and dissolution behavior in biorelevant media upon production and after storage in two packaging systems (Glass and Activ-Vials(™)). RESULTS AND DISCUSSION Spray drying the same formulation from two different solvents led to different physicochemical properties, dissolution behavior and long-term stability. The dissolution behavior and long-term stability also varied significantly among excipients. The viscosity of the polymer and the packaging material proved to be important to the long-term stability. CONCLUSION For spray-dried products containing fenofibrate, the excipients were ranked according to dissolution and stability performance as follows: PVP derivatives >> HPMC 2910/15, HPMCAS-MF, HP-β-CD >> PVP:PVA 2:8. EtOH 96% proved superior to acetone/water for spray drying with polymers. The results were used to propose a general approach to developing spray-dried formulations of poorly soluble drugs.

Int J Pharm 2011; 414:48-55. [PMID: 21565260 DOI: 10.1016/j.ijpharm.2011.04.065] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2011] [Revised: 04/23/2011] [Accepted: 04/27/2011] [Indexed: 10/18/2022]
Abstract
The stability of solid dispersions (SD) during storage is of concern. We prepared the pH-modulated SD (pSD) and compressed tablets consisting of polyethylene glycol (PEG) 6000 as a carrier, drug and MgO (alkalizer). Telmisartan (TEL), an ionizable poorly water-soluble drug, was chosen as a model drug. The changes in physicochemical factors such as the dissolution rate, drug crystallinity, microenvironmental pH (pH(M)) and intermolecular interactions of the pSD and the tablets were investigated over 3 months under different temperature and relative humidity (RH) conditions: refrigerator (5-8 °C), 25 °C/32% RH, 25 °C/55% RH, 25 °C/75% RH, 40°C/32% RH, 40 °C/55% RH, and 40 °C/75% RH. Differential scanning calorimetry (DSC) analysis of all samples revealed no distinct changes in the drug melting point. In contrast, powder X-ray diffraction (PXRD) diffractograms revealed that samples stored at 40 °C/75% RH for 1 month, 25 °C/75% RH for 3 months and 40 °C at all humidity conditions for 3 months showed gradual recrystallization of the drug. Fourier transform infrared (FTIR) spectra indicated a reduced intensity of intermolecular interactions between TEL and MgO in the pSD and tablet. The pH(M) also gradually decreased. These altered physicochemical factors under the stressed conditions resulted in decreased dissolution profiles in intestinal fluid (pH 6.8). In contrast, the dissolution rate in gastric fluid (pH 1.2) was almost unchanged because of the high intrinsic solubility of TEL at this pH.
