PURPOSE A multicenter, 2-visit, open-label, 4-week study was conducted to determine the acceptability of hydroxypropyl cellulose ophthalmic inserts in adult patients with a history of dry eye syndrome (DES). METHODS At visit 1, patients (N = 520) were evaluated, screened by slit-lamp biomicroscopy, and completed the Ocular Surface Disease Index (OSDI), a validated measure of quality of life. ...

BACKGROUND Lignin is a complex polymer which inhibits the enzymatic conversion of cellulose to glucose in lignocellulose biomass for biofuel production. Cellulase enzymes irreversibly bind to lignin, deactivating the enzyme and lowering the overall activity of the hydrolyzing reaction solution. Within this study, atomic force microscopy (AFM) is used to compare the adhesion forces between cellu...

Lipitor tablets for oral administration contain 10, 20, 40 or 80 mg atorvastatin and the following inactive ingredients: calcium carbonate, USP; candelilla wax, FCC; croscarmellose sodium, NF; hydroxypropyl cellulose, NF; lactose monohydrate, NF; magnesium stearate, NF; microcrystalline cellulose, NF; Opadry White YS-1-7040 (hypromellose, polyethylene glycol, talc, titanium dioxide); polysorbat...

Building Integrated Photovoltaic (BIPV) glazings are promising technologies with the benefits of electricity generation, solar shading and building energy savings. A new approach is to integrate BIPV windows thermotropic materials such as Hydroxypropyl Cellulose (HPC) hydrogel, which offers adaptive advantages for systems respond time-varying weather conditions but also enhances PV generation. ...

Given the importance of the development of electrochromic devices (ECDs) for technological applications small devices with Prussian blue (PB)/hydroxypropyl cellulose (HPC) electrolyte/CeO2TiO2 configuration were assembled and characterized. The films of PB were obtained galvanostaticaly by applying 0.45 mA for 300 s. The cyclic voltammetry, in 1 mol L 1 KCl solution, of these films showed a red...

The aim of this study was to evaluate the effect three coformers and five disintegrants in granulation formulation on dissociation cocrystal during process by monitoring wet with probe-type low-frequency Raman (LF-Raman) spectroscopy. As model cocrystals, paracetamol (APAP)-oxalic acid (OXA), APAP-maleic (MLA), APAP-trimethylglycine (TMG) were used. recipe containing cocrystals performed over t...

Glipizide is mainly absorbed in the proximal areas of the gastrointestinal tract. The purpose of this study was formulation and evaluation of mucoadhesive films to prolong the stay of drug in its absorption area. Glipizide was formulated in a mucoadhesive film that could be retained in the stomach for prolonged intervals. Polymeric films were designed with various compositions of hydroxypropyl ...

The development of liquid crystal materials via nanotechnology has become an interesting subject research in optical material chemistry. One the significant nanomaterials is cellulose-based nanoparticles. In this review article, we highlighted classification (LCs), and types cellulose-NPs their characterization as LCs materials. Finally, present our promising data on synergistic effect behavior...

3D printing of oral solid dosage forms is a recently introduced approach for dose personalisation. Fused deposition modelling (FDM) one the promising and heavily researched techniques in pharmaceutical field. However, successful application this technique relies greatly on mass manufacturing physically chemically stable filaments, that can be readily available as shelf item to printed on-demand...
