Floating drug delivery systems (FDDS) are utilized to target discharge in the stomach or upper parts of intestine. Famotidine has been most extensively used for management peptic ulcer various decades. The current study concerns development and evaluation floating tablets famotidine which, after oral administration, planned extend gastric residence time, enhance bioavailability aim ulcer. A FDD...

Mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. Carbomers are among the best mucosa-adhesive materials known. The aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing Carbomers, either alone or in combination, to the data obtained from assessing the d...

Buccoadhesive tablets of Metclopramide Hydrochloride were fabricated with objective of avoiding extensive first pass metabolism and to prolong its duration of action with reduction in dosing frequency. The mucoadhesive polymers used in the formulations were Carbopol 934P, Chitosan, HPMC K4M and HPMC K15M. Tablets were prepared by direct compression method using polymer in different ratios. The ...

AIM Carbomer cement represents a novel glass-ionomer which gradually mineralises into fluoroapatite. Purpose of this study was to evaluate microleakage around restorations in deciduous teeth made with composite resin, conventional glass-ionomer cement, resin-modified glass-ionomer cement and carbomer/fluoroapatite-enhanced glass-ionomer cement. MATERIALS AND METHODS A group of 40 primary uppe...

Purnose The incorporation of polymers into artificial tears both increases the thickness of the precorneal tear film and decreases the rate of drainaae of the for8nulations. On the basis of these effects, we hypothesized that a time study of the artificial increase in tear volume induced by such formulations could be a useful method of assessing their precorneal residence time. Methods New Zeal...

OBJECTIVES The aim of the present study was to investigate the caries-preventive effect of sealants produced with a high-viscosity glass-ionomer with an elevated powder-liquid ratio (ART), of having energy added to this glass-ionomer, and that of glass-carbomer, in comparison to that of resin composite sealants. METHODS The randomized controlled trial covered 407 children, with a mean age of ...

BACKGROUND/AIMS Carbomers are widely used in products for the treatment of dry eye; however, the polymer gel thins on addition of probes (for example, fluorescein salt) confounding the comparison of products by objective clinical tests such as spectrophotofluorimetry or scintigraphy. A novel method of radiolabelling carbomer gels, with minimum change to their rheology, has permitted the non-inv...
