The aim of this research is to quantify the competitive adsorption of a whey protein concentrate (WPC) and hydroxypropyl-methyl-cellulose (HPMC so called E4M, E50LV and F4M) at the air-water interface by means of dynamic surface tensiometry and Brewster angle microscopy (BAM). These biopolymers are often used together in many food applications. The concentration of both protein and HPMC, and th...
The main objective of this research is to develop and characterize a series of carbopol 934 (CP) hydroxypropyl methylcellulose (HPMC) and a combination of carbopol-HPMC as a gel base for topical delivery of nystatin. The drug level was held constant at 1.72% w/w and the level of propylene glycol which is used as a co-solvent and penetration enhancer was also kept constant at 2% w/w. The total l...
Hydroxypropyl methylcellulose (HPMC) is a biopolymer that is biodegradable, environmentally friendly, and bio-friendly. Owing to its unique chemical structure, HPMC can reduce the coefficient of friction (COF) and frictional wear and thus possesses excellent lubrication properties. HPMC has good dissolvability in specific solvents. The present research focuses on the reversible dissolution reac...
A novel method for preparing eco-biodegradable lubricant based on hydroxypropyl methylcellulose (HPMC) via hydration process is demonstrated. The smooth and homogeneous HPMC coating has a uniform thickness (~35 μm). It has been demonstrated that the preparation parameters play a critical role in controlling the lubricating behavior of the coating; in addition, excess HPMC and water concentratio...
UNLABELLED BACKGROUND Diets producing a high glycemic response result in exaggerated insulin secretion which induces hepatic lipogenesis, contributing to development of insulin resistance and fatty liver. Viscous dietary fibers blunt the postprandial rise in blood glucose, however their effect on type 2 diabetes and obesity are not entirely known. This study examined the effect of chronic co...
celecoxib is used in the treatment of osteoarthritis, rheumatoid arthritis, acute pain, joint inflammation and sport injuries. long term administration of the drug results in such complications as gastrointestinaland renal disturbances and cardio-vascular complications. the main objective of the present study was to investigate the feasibility of delivering celecoxib incorporated in gel formula...
SUMMARY Roller compacted hydrophilic polymer combinations were used to formulate verapamil hydrochloride (HCl) extended release hydrophilic matrix tablets. The effect of roller compaction (RC) parameters on the properties of blended polymers, tablets and drug release were investigated. RC granulation improved the powder properties without affecting the pharmacotechnical properties or the drug r...
محصولات لعاب دهی و سوخاری شده طی فرایند تولید روغن فراوانی را جذب میکنند، بنابراین کاهش میزان روغن جذب شده در اینگونه محصولات، میتواند در سلامت جامعه نقش داشته باشد. در این تحقیق اثر هیدروکسیپروپیلمتیلسلولز (hpmc) افزوده شده به آردزنی اولیه و لعاب ناگت ماهی سارم بر کاهش جذب روغن در محصول نهایی بررسی شد. تیمارها شامل تیمار شاهد (فاقد hpmc در روکش)، تیمار a (حاوی دو درصد hpmc در آردزنی اولیه...
OBJECTIVE High-viscosity hydroxypropylmethylcellulose (HV-HPMC) is a modified cellulose fiber that produces a viscous gel in the gastrointestinal tract. Clinical trials demonstrate that consumption of HV-HPMC significantly lowers cholesterol, but limited information has been available on the influence of HV-HPMC on postprandial insulin and glucose responses. The objective of this investigation ...
Abstract Background and purpose: The dissolution of a drug has an important role in its bioavailability. Any change in the physico-chemical properties can result in changes in the drug release, and furthermore in its bioavailability. In order to overcome such changes, it is necessary to determine the storage conditions required for obtaining a desired drug release. Materials and methods: Di...
