Abstract
Drug delivery to the buccal mucosa is one of the most convenient ways to treat common mouth problems. Here, we propose a spray-dried re-dispersible mucoadhesive controlled release gargle formulation to improve the efficacy of chlorhexidine. The present investigation portrays an approach to get stable and free-flowing spray-dried porous aggregates of chlorhexidine-loaded sodium alginate nanoparticles. The ionic gelation technique aided with the chlorhexidine's positive surface charge-based crosslinking, followed by spray drying of the nanoparticle's dispersion in the presence of lactose- and leucine-yielded nano-aggregates with good flow properties and with a size range of about 120-350 nm. Provided with the high entrapment efficiency (87%), the particles showed sustained drug release behaviors over a duration of 10 h, where 87% of the released drug got permeated within 12 h. The antimicrobial activity of the prepared formulation was tested on S. aureus, provided with a higher zone of growth inhibition than the marketed formulation. Aided with an appropriate mucoadhesive strength, this product exhibited extended retention of nanoparticles in the throat region, as shown by in vivo imaging results. In conclusion, the technology, provided with high drug retention and extended effect, could be a potential candidate for treating several types of throat infections.

Abstract
BACKGROUND The purpose of the study was to investigate the effects of cefuroxime axetil combined with Xingpi Yanger granules on the treatment of upper respiratory tract infection accompanied by diarrhea and on serum gastrin (GAS), motilin (MOT), and somatostatin (SS) levels in children. METHODS In total, 124 children with upper respiratory tract infection accompanied by diarrhea admitted to the department of pediatrics in our hospital from May 2019 to May 2020 were selected and divided into a study group (n=62) and a reference group (n=62), according to admission number. The reference group children received routine treatment, while the children in the study group were treated with cefuroxime axetil combined with Xingpi Yanger granules. After treatment, each clinical index of the children in both groups was detected to evaluate the clinical efficacy of the different treatment methods. RESULTS There were no significant differences in gender ratio, average age, mean body temperature, mean duration of diarrhea, average weight, or place of residence between the 2 groups (P>0.05); the total clinical effective rate after treatment in the study group was significantly higher than that in the reference group (P<0.05); the dehydration correction time, antipyretic time, antidiarrheal time, and total treatment time in the study group were all significantly lower than those in the reference group (P<0.001); the serum GAS and MOT levels at T1, T2, and T3 in the study group were significantly lower than those in the reference group (P<0.001), whereas the SS levels at T1, T2, and T3 in the study group were significantly higher than those in the reference group (P<0.001); and the incidence of adverse reactions of the children in the study group was significantly lower than that in the reference group (P<0.05). CONCLUSIONS Cefuroxime axetil combined with Xingpi Yanger granules can significantly lower serum GAS, MOT, and SS levels and shorten treatment time in children with upper respiratory tract infection accompanied by diarrhea, with significant clinical efficacy and high safety, and is thus worthy of application and promotion.

Abstract
Tableting by direct compression (DC) is one of the simplest and most cost-effective drug manufacturing approaches. However, most active pharmaceutical ingredients (APIs) and excipients lack the compression and flow properties required to meet the needs of high-speed industrial tablet presses. Therefore, the majority of DC APIs and excipients are modified via processing/co-processing particle engineering techniques to boost their properties. Spray drying is one of the most commonly employed techniques to prepare DC grades of APIs and excipients with prominent advantages. This review aims to present an overview of the commercially marketed and investigationally-prepared DC APIs and excipients produced by spray drying.

Abstract
In this work, the tabletability and dissolution of spray-dried forms of naproxen and its sodium salt were compared with those of unprocessed drugs. Solutions of naproxen or naproxen sodium alone or with HPMC (5% w/w of drug content) were spray dried. Scanning electron micrographs showed that naproxen sodium spray-dried particles were spherical, whereas those of naproxen were non-spherical but isodiametric. Powder x-ray diffraction and thermal analysis indicated that co-spray drying with HPMC resulted in reduced crystallinity of naproxen and higher naproxen sodium dihydrate content. FTIR and Raman analysis showed shifting, merging or elimination of bands in the spectra of the co-spray dried products signifying solid-state alterations. When mixed with suitable processing aids (7% w/w), all co-spray dried powders produced satisfactory tablets in the pressure range 73-295 MPa. Conversely, physical mixtures of naproxen compressed with the same aids failed tableting, whereas naproxen sodium produced weak tablets. Dissolution tests showed significant improvement for co-spray dried drugs tablets. Therefore, since the large therapeutic doses of naproxen and sodium naproxen limit the use of tableting aids, the improved compaction and dissolution performance of the spray-dried forms may be a formulation alternative.

Abstract
Developing a new excipient and obtaining its market approval is an expensive, time-consuming, and complex process. The application of a multivariate analytical approach - principal component analysis (PCA) - in combination with the design of experiments (DoE) approach can make the process of developing co-processed excipient cost-effective and rapid. The present investigation was aimed to demonstrate the applicability of the DoE approach and PCA in developing a co-processed excipient by using the spray drying technique. The preliminary studies suggested a significant effect of inlet air temperature (X 1) and polymer ratio [chitosan chlorhydrate (CC): mannitol - X 2) on critical product characteristics so they were selected as independent variables in 32 full factorial design. The result of regression analysis suggested a significant effect of both independent variables on all response variables. The PCA of practically obtained value suggested a strong effect of all the selected response variables on the model. The prepared co-processed excipient had better tableting properties compared to the physical mixture of excipients and was able to accommodate more than 80% drug without compromising the flow property and compressibility. The present investigation successfully proved the applicability PCA and DoE approach as an effective and rapid tool for optimizing process parameters and formulation composition for preparing a directly compressible co-processed excipient.

Abstract
The development of orodispersible tablets (ODTs) for poorly soluble and poorly flowable drugs via direct compression is still a challenge. This work aimed to develop ODTs of poorly soluble drugs by combining cyclodextrins that form inclusion complexes to improve wetting and release properties, and directly compressible co-processed excipients able to promote rapid disintegration and solve the poor flowability typical of inclusion complexes. Carbamazepine (CBZ) and hydroxypropyl-β-cyclodextrin (HPβCD) were used, respectively, as a model of a poorly soluble drug with poor flowability and as a solubilizing agent. Specifically, CBZ-an antiepileptic and anticonvulsant drug-may benefit from the studied formulation approach, since some patients have swallowing difficulties or fear of choking and are non-cooperative. Prosolv® ODT G2 and F-Melt® type C were the studied five-in-one co-processed excipients. The complex was prepared by kneading. Flow properties of all materials and main properties of the tablets were characterized. The obtained results showed that ODTs containing CBZ/HPβCD complex can be prepared by direct compression through the addition of co-processed excipients. The simultaneous use of co-processing and cyclodextrin technologies rendered ODTs with an in vitro disintegration time in accordance with the European Pharmacopoeia requirement and with a fast and complete drug dissolution. In conclusion, the combination of five-in-one co-processed excipients and hydrophilic cyclodextrins may help addressing the ODT formulation of poorly soluble drugs with poor flowability, by direct compression and with desired release properties.
