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 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...

A six-month repeated-dose dermal toxicity study fo11owed by a 30-day recovery test of hydrophobically modified hydroxypropyl methylcellulose (HM-HPMC), a new ceLlulose derivative used as a thickener for topical pharmaceuticals, was conducted using rats, Aqueous paste of HM-HPMC was applied to the skin ofrats once daily at dose levels up to 60 mg/kglday, which was the highest dose that could be ...
متن کاملSedimentation Study of Biphasic Calcium Phosphate Particles
Injectable calcium phosphate (CaP) biomaterial is considered as an injectable bone substitute (IBS). It was developed to minimize invasive surgery in various applications in orthopedic and dental surgery. The IBS considered of a polymer solution mixed with biphasic calcium phosphate (BCP) ceramic particles. Two particle sizes of BCP (40-80 and 80-200μm) were used and the weight ratio was 40%. T...
متن کاملComparative evaluation of biphasic calcium phosphate and biphasic calcium phosphate collagen composite on osteoconductive potency in rabbit calvarial defect
BACKGROUND The aim of this study was to determine the osteoconductivity of biphasic calcium phosphate collagen composite (BCPC) in rabbit calvarial defect model by comparing with biphasic calcium phosphate (BCP). Four 8 mm diameter bicortical calvarial defects were made in ten rabbits. Each of the defects was randomly assigned and filled with 1) collagen sponge, 2) BCP, 3) BCPC, and 4) nothing ...
