an oral suspension could a suitable dosage form for the geriatric patients. the calcium alginate coated ion exchange resinate of propranolol hydrochloride were prepared using amberlite ir-120 by solvent evaporation. microcapsules of propranolol hydrochloride resinate were prepared by solvent evaporation technique,the suspensions were prepared by using deionised water as the vehicle. methyl cell...

background: the most important limitation of glass ionomer cements (gics) is the weak mechanical properties. our previous research showed that higher mechanical properties could be achieved by addition of forsterite (mg2sio4) nanoparticles to ceramic part of gic. the objective of the present study was to fabricate a glass ionomer- mg2sio4 nanocomposite and to evaluate the effect of addition of ...

objective: evidence shows that the powder/liquid mixing ratio recommended by the manufacturers is often not respected when mixing the glass ionomer (gi) powder and liquid, yielding a gi cement with disproportionate powder/liquid ratio. considering the confirmed effect of powder/liquid ratio on the gi properties, and more importantly, its fluoride release potential, this study aimed to assess th...

The aim of this study was to synthesize Ag-nanoclay composite by solid ion exchange, then characterize, and evaluate the antibacterial activity. This newly introduced ion exchange is a simple and low cost technique, which provides a quicker method. Without chemical treatment, nanoclay was subjected to an ion exchange process in media containing molten salt of silver at 300 and 400 °C and at dif...

introduction: glass-ionomer cements (gics) are one of the most important dental restorative biomaterials. the aim of this study was to synthesize glass-ionomer‒silk fiber composite and evaluate the effect of adding natural degummed silk fiber on the bioactivity and the ability to release fluoride by glass-ionomer cement. materials and methods: in this study, commercial fuji ii glass-ionomer cem...

microencapsulation has become a common technique in the production of controlled release dosage forms. many results have been reported, concerning the use of alginate beads as controlled release drug formulations. alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...
