Abstract
Pharmaceutical tablets are a popular solid dosage form and have a significant ratio in the available solid dosage forms. They are a popular choice for patients due to the ease of administration as well as for pharmaceutical manufacturers due to the low cost of manufacturing, packaging, and other pharmaceutical parameters. However, the drug powder should either be crystalline or turned into a granular form using wet-dry granulation techniques to improve the flow and compressibility. The valsartan drug, which is commonly used as an antihypertensive drug, is an amorphous drug and has an angle of repose of more than 40º. Therefore, it needs to be converted into a granular form. This work uses the spherical crystals of the valsartan drug because they flow well and can be used for pharmaceutical tablets. Different process parameters, such as mixing speed, mixing time, and temperature, were optimized to obtain effective process parameters. The final batch of spherical crystals of valsartan had an angle of repose of 27.23º, which shows that prepared spherical crystals flow well.

Abstract
AIM In the current study, efforts are being made to prepare Inhalable Silibinin loaded solid lipid nanoparticles (SLNs) with narrow size distribution with improved bioavailability. METHODS SLNs were formulated by high shear homogenisation method SLNs were characterised, including Differential Scanning Calorimetry (DSC), Fourier transform infra-red spectroscopy (FTIR), particle size analysis, entrapment efficiency with Aerodynamic behaviour. The MTT assay was performed against A549 cell line, to measure their anticancer cell activity with In vivo study. RESULTS Optimized formulation exhibited spherical surface with a mean particle size of 221 ± 1.251 nm, PI of 0.121 ± 0.081, zeta potential of -4.12 ± 0.744. Aerodynamic behaviour such as Mass median aerodynamic diameter (MMAD) and Geometric size distribution (GSD) were found to be 5.487 ± 0.072 and 2.321 ± 0.141 respectively proved formulation is suitable for inhalation. In vitro cellular efficacy against A549 cells, revealed that the optimised formulations were more effective and potent. CONCLUSION The Inhalable SLNs approach was successfully engineered and administered to the lungs safely without causing any problems.

Abstract
This study provides a comprehensive assessment of the parameters of the spherical crystallization process and their impact on the micromeritic properties of lactose spherical agglomerates. A recently introduced definitive screening design was used to study various process parameters, with particular focus on building predictive models. The parameters included were: lactose solution concentration; volume ratio between the antisolvent and the whole crystallization system; crystallization system temperature; velocity of the addition of the lactose water solution; agitation velocity; and agitation time after whole addition of the lactose solution. Their effects on process yield, particle size parameters D10, D50 and D90, particle size distribution, morphological properties (roundness, solidity) and Hausner ratio were studied. Active effects were identified for all of these responses, with quadratic and interaction effects included. Lactose concentration, volume ratio, crystallization system temperature, and agitation velocity were identified as critical process parameters. For every response, a statistical model was built, where those for Hausner ratio, yield and roundness provided the best predictive performances. Based on these models, D10 and yield were successfully optimized. Definitive screening design proved as useful especially in the screening phase; however, additional experiments are needed to build models with high predictive power for all of these responses.

Adv Pharm Bull 2017; 7:557-567. [PMID: 29399545 PMCID: PMC5788210 DOI: 10.15171/apb.2017.067] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2017] [Revised: 09/21/2017] [Accepted: 09/24/2017] [Indexed: 12/01/2022] Open
Abstract
Purpose: Triple solid dispersion adsorbates (TSDads) and spherical agglomerates (SA) present new techniques that extensively enhance dissolution of poorly soluble drugs. The aim of the present study is to hasten the onset of hypoglycemic effect of glimepiride through enhancing its rate of release from tablet formulation prepared from either technique. Methods: Drug release from TSDads or SA tablets with different added excipients was explored. Scanning electron microscopy (SEM) and effect of compression on dissolution were illustrated. Pharmacodynamic evaluation was performed on optimized tablets. Results: TSDads & SA tablets with Cross Povidone showed least disintegration times of 1.48 and 0.5 min. respectively. Kinetics of drug release recorded least half-lives (54.13 and 59.83min for both techniques respectively). Cross section in tablets displayed an organized interconnected matrix under SEM, accounting for the rapid access of dissolution media to the tablet core. Components of tablets filled into capsules showed a similar release profile to that of tablets after compression as indicated by similarity factor. The onset time of maximum reduction in blood glucose in male albino rabbits was hastened to 2h instead of 3h for commercial tablets. Conclusion: After optimization of tablet excipients that interacted differently with respect to their effect on drug release, we could conclude that both amorphisation and spheronization were equally successful in promoting in vitro dissolution enhancement as well as providing a more rapid onset time for drug action in vivo.
