Polyvinyl pyrrolidone (PVP) in cataract surgery.
Early reformation of the anterior chamber after intraocular surgery is of paramount importance, its absence or delay leading to peripheral anterior synechiae and aphakic glaucoma (Troncoso, 1933; Kronfeld and Grossman, 1941; McLean, I94I; Meyer and Sternberg, 1950). Selinger (1937) injected air after cataract operations to restore the normal curvature of the cornea. He concluded that air preven...
متن کاملEffect of Polyvinyl Pyrrolidone and Ethyl Cellulose Concentration on Release Profile and Kinetics of Glibenclamide Extended Release Dosage Form System
The aim of present work was to optimize the effect of Ethyl Cellulose (EC) and Polyvinyl Pyrrolidone (PVP) concentration in extended release solid dispersion of Glibenclamide using combination of hydrophilic and hydrophobic polymers such as Polyvinyl Pyrrolidone and Ethyl cellulose. The advantage of solid dispersion technique provides a unique approach to particle size reduction and increased r...
متن کاملMetoprolol tartrate Containing Glutaraldehyde Cross-linked Chitosan- Polyvinyl pyrrolidone Matrix Transdermal Patch: Preparation and Characterization
The present study was undertaken to develop a suitable transdermal matrix patch of Metoprolol tartrate with different proportions of polyvinyl pyrrolidone (PVP) and chitosan crosslinked with glutaraldehyde (GA). The prepared transdermal patches were subjected to different physicochemical evaluations such as thickness, tensile strength, folding endurance, drug content, swellability, surface pH, ...
متن کاملFormulation and physicochemical characterization of buccoadhesive microspheres containing diclofenac sodium.
PURPOSE The present study involves preparation and evaluation of diclofenac buccal-mucoadhesive microparticles for prolongation of buccal residence time. METHODS The microparticles were prepared by modified double-emulsion dehydration method (O1/W/O2) using sodium carboxymethylcellulose (CMC-Na) as mucoadhesive polymer. Calcium chloride was used as a cross-linking agent. Buccal-mucoadhesive m...
