Doke, Vishakha Vishwanath;Gupta, Khemchand;Khutle, Nilesh M.;Desai, Abhishek research published 《 Formulation and evaluation of self-nanoemulsifying drug delivery system of Ezetimibe》, the research content is summarized as follows. The contemporary research was done with the goal of development and characterization of self-emulsifying drug delivery system of Ezetimibe (EZE) which is poorly water soluble and also to enhance its solubility in biol. fluid, in order to improve dissolution as well as permeability which would lead to enhanced oral bioavailability of drug. Liquid SNEDDS (L-SNEDDS) was formulated using Capmul MCM C8 EP, Cremophore RH 40 and Labrafil M 2125 CS as oil, surfactant and co-surfactant resp. Optimized L-SNEDDS formulation was found to be efficient with average %T of 99.5%, drug content of 98.43%, flask inversion 0 numbers, average particle size of 36.7 nm, zeta potential of -57.5 mV, Polydispersibility index in of 0.119. Also, the in vitro release profile of drug from L-SNEDDS encapsulated in hard gelatin capsules was evaluated in different dissolution media viz. simulated gastric fluid and simulated intestinal fluid. For the drug, more than 95% cumulative release was observed within 30 min exclusive of the pH of the medium. The L-SNEDDS were adsorbed on solid support and then mixed with tablet blends and compressed into tablets. Further, no adverse changes in globule size, shape, zeta potential of SNEDDS and dissolution profile were apparent on conversion to solid powder form and tablet form.

Doty, Anna C.;Wilson, A. Dan;Forse, Lisa B.;Risch, Thomas S. research published 《 Biomarker Metabolites Discriminate between Physiological States of Field, Cave and White-nose Syndrome Diseased Bats》, the research content is summarized as follows. Anal. of volatile organic compound (VOC) emissions using electronic-nose (e-nose) devices has shown promise for early detection of white-nose syndrome (WNS) in bats. Tricolored bats, Perimyotis subflavus, from three sep. sampling groups defined by environmental conditions, levels of phys. activity, and WNS-disease status were captured temporarily for collection of VOC emissions to determine relationships between these combinations of factors and physiol. states, Pseudogymnoascus destructans (Pd)-infection status, and metabolic conditions. Physiol. active (non-torpid) healthy individuals were captured outside of caves in Arkansas and Louisiana. In addition, healthy and WNS-diseased torpid bats were sampled within caves in Arkansas. Whole-body VOC emissions from bats were collected using portable air-collection and sampling-chamber devices in tandem. Electronic aroma-detection data using three-dimensional Principal Component Anal. provided strong evidence that the three groups of bats had significantly different e-nose aroma signatures, indicative of different VOC profiles. This was confirmed by differences in peak numbers, peak areas, and tentative chem. identities indicated by chromatograms from dual-column GC-analyses. The numbers and quantities of VOCs present in whole-body emissions from physiol. active healthy field bats were significantly greater than those of torpid healthy and diseased cave bats. Specific VOCs were identified as chem. biomarkers of healthy and diseased states, environmental conditions (outside and inside of caves), and levels of physiol. activity. These results suggest that GC/E-nose dual-technologies based on VOC-detection and analyses of physiol. states, provide noninvasive alternative means for early assessments of Pd-infection, WNS-disease status, and other physiol. states.

Duffield, Sophie;Da Via, Luigi;Bellman, Amelia Celeste;Chiti, Fabio research published 《 Automated High-Throughput Partition Coefficient Determination with Image Analysis for Rapid Reaction Workup Process Development and Modeling》, the research content is summarized as follows. With this work, the authors explore the application of a novel image anal. algorithm in combination with a high-throughput automated workflow to extract partition coefficient measurements and full mass balance from small-scale samples. An image anal. algorithm was developed in MATLAB R2018b to determine the volume of the aqueous and organic phases of the biphasic samples with 95% accuracy. The automated workflow used <1% of the typical reagent amounts and provided up to 94% time savings when compared with the conventional partition coefficient determination studies. This approach also proves that it is possible to build thermodn. models for liquid-liquid equilibrium process steps using small-scale vessels (8 mL) and identify the impact of varying process parameters in silico. The model could predict the system behavior at a kilo scale and resulted in an optimized set of process conditions that increased the product recovery from 88 to 94% theor. The good agreement between the model and the exptl. data also enabled the impact of process parameters on a critical impurity to be determined, supporting risk assessment and quality by design activities for the case study highlighted.

This work aimed to develop, optimize, and evaluate the hypoglycemic activity of P. ligularis leaves extract (PLE) loaded self-emulsifying drug delivery system (SEDDS). The formulation components (oil, surfactant, and co-solvent) were selected based on the solubility studies. A Box-Behnken design (BBD) with 27 treatments was employed to find the optimal composition of PLE-SEDDS, analyzing the droplet size as the response variable. The polydispersity index (PDI) and zeta potential parameters were also measured. The pharmacol. activity was evaluated through a glucose tolerance test. According to ANOVA for the droplet size variable, the linear model was highly significant (p < 0.001), and oil, surfactant, co-solvent, and silicone polymer (PDMSHEPMS) content and their interactions were statistically significant. The final composition of PLE-SEDDS was castor oil, Cremophor EL, propylene glycol, PDMSHEPMS in proportions of 31: 120: 80: 30, resp. The amount of P. ligularis extract incorporated in the formulation was 20%. The final formulation showed a 45.93 ± 1.02 nm droplet size with a PDI 0.27 ± 0.03 and zeta potential -10.92 ± 0.42 mV. Finally, in the in vivo glucose tolerance test, PLE-SEDDS improved hypoglycemic activity compared to the unformulated extract

El Nashar, Nourhan F.;Sultan, Amal A.;El Maghraby, Gamal M. research published 《 Self-dispersing self-assembling systems for controlled oral delivery of gliclazide》, the research content is summarized as follows. Self-microemulsifying systems undergo self-dispersion to form microemulsion with subsequent self-assembly to form liquid crystalline (LC) and/or gel phases. These transitions modulate the release and absorption pattern of loaded drug. Accordingly, the primary objective was to evaluate these phases with respect to gliclazide release and absorption after oral administration. Pseudoternary phase diagrams were constructed using Peceol as oil, Gelucire 50/13 as surfactant and Transcutol as co-surfactant with Gelucire and Transcutol being used at 1:1 or 2:1, weight ratios. Microemulsion, LC and gel formulations were selected from these phase diagrams and were loaded with gliclazide. The selected systems were evaluated for gliclazide release which was conducted using continuous pH variation to mimic the gastrointestinal conditions. Optimum systems were subjected to in vivo evaluation. The in vivo study involved monitoring blood glucose level of diabetic rats after oral administration of gliclazide in aqueous suspension, microemulsion, LC and gel systems. Microemulsion liberated gliclazide rapidly and the rate of drug release was reduced in case of LC with further slowing in case of gel system. Interestingly, LC and gel systems liberated gliclazide steadily via zero order release kinetics. Microemulsion provided rapid reduction of blood glucose level but was not able to sustain this effect. LC and gel systems provided sustained effect and enhanced the bioavailability as shown from significant increase in the area under glucose reduction curve compared to both microemulsion and suspension form. The study thus introduced LC and gel phase as controlled release systems for oral delivery of gliclazide.

Daryab, Mahshid;Faizi, Mehrdad;Mahboubi, Arash;Aboofazeli, Reza research published 《 Preparation and characterization of lidocaine-loaded, microemulsion-based topical gels》, the research content is summarized as follows. Microemulsion-based gels (MBGs) were prepared for transdermal delivery of lidocaine and evaluated for their potential for local anesthesia. Lidocaine solubility was measured in various oils, and phase diagrams were constructed to map the concentration range of oil, surfactant, cosurfactant, and water for oil-in-water (o/w) microemulsion (ME) domains, employing the water titration method at different surfactant/cosurfactant weight ratios. Refractive index, elec. conductivity, droplet size, zeta potential, pH, viscosity, and stability of fluid o/w MEs were evaluated. Carbomer 940 was incorporated into the fluid drug-loaded MEs as a gelling agent. Microemulsion-based gels were characterized for spreadability, pH, viscosity, and in-vitro drug release measurements, and based on the results obtained, the best MBGs were selected and subsequently subjected to ex-vivo rat skin permeation anesthetic effect and irritation studies. Data indicated the formation of nano-sized droplets of MEs ranging from 20-52 nm with a polydispersity of less than 0.5. In-vitro release and ex-vivo permeation studies on MBGs showed significantly higher drug release and permeation in comparison to the marketed topical gel. Developed MBG formulations demonstrated greater potential for transdermal delivery of lidocaine and advantage over the com. available gel product, and therefore, they may be considered as potential vehicles for the topical delivery of lidocaine.
