Hydroxypropyl methylcellulose in drug delivery
Hydroxy propyl methyl cellulose can be used in the development of different drug delivery technology. Nowadays it is a widely used polymer and different viscosity grade of this polymer is available. The hydrophilic and hydrophobic form (both variants) of this polymer is also available. This study includes a review of this polymer on use in different drug delivery system mosty focusing on more r...
متن کاملAntioxidant properties of galantamine hydrobromide.
The antioxidant properties of galantamine hydrobromide ((4alpha,6beta)-4a,5,9,10,11,12-hexahydro-3-methoxy-11-methyl-6H-benzofuro[3a,3,2-ef][2]benzazepin-6-ol hydrobromide) were studied in vitro, using luminol-dependent chemiluminescence and spectrophotometry. It was found that this compound was a scavenger of reactive oxygen species (ROS). By comparing the antioxidant effects of galantamine ((...
متن کاملIn Vitro Studies of Controlled Release Alfuzosin Matrix Tablets Prepared with Ethylcellulose and Hydroxypropyl Methylcellulose
Extended release formulation of alfuzosin, an a-antagonist used for prostatic hypertrophy, is available in market. It is convenient for older patients to take only one tablet a day. Marketed alfuzosin formulation is three layered geomatrix tablet that requires special facilities, high cost, more time and complex operation than normal direct compression formulation. Therefore, a less compl...
متن کاملFormulation and Evaluation of Hydroxypropyl Methylcellulose-based Controlled Release Matrix Tablets for Theophylline
The objectives of the study were to formulate hydroxypropyl methyl cellulose-based controlled release matrix tablets for theophylline with varying drug:polymer ratios (1:1 and 1:2) and differing tablet hardness (5, 6 and 7 kg/cm(2)), and to evaluate the tablet's physico-chemical properties such as hardness, uniformity of weight, friability, drug content and in vitro drug release. Initially, gra...
متن کاملModeling of drug release from delivery systems based on hydroxypropyl methylcellulose (HPMC).
The objective of this article is to review the spectrum of mathematical models that have been developed to describe drug release from hydroxypropyl methylcellulose (HPMC)-based pharmaceutical devices. The major advantages of these models are: (i) the elucidation of the underlying mass transport mechanisms; and (ii) the possibility to predict the effect of the device design parameters (e.g., sha...
