Sodium hyaluronate (SH) is recognized as the strongest natural humectant, since it contains a large number of hydroxyl and carboxyl groups in its structure, can absorb 1000 times own weight water. The porcine acellular dermal matrix (pADM) has been widely used biological materials for activities, such promoting cell proliferation wound healing. Enhancing hydrophilic moisturizing properties pADM...

the objective of this work was to develop and evaluate the levofloxacin hemihydrate floating formulations (f1-f9). selection of optimized batch was done by model dependent approach and novel mathematical approach. f1-f9 batches were prepared by direct compression method using gelucire 43/01 (hydrophobic) and hydroxypropylmethylcellulose (hydrophilic) polymer in different ratios. the floating ta...

The objective of the study was to formulate controlled release matrix tablets of losartan Potassium by using a combination of hydrophilic synthetic polymer like poly (ethylene oxides) and natural gums like xanthan gum, karaya gum and guar gum. A combination of synthetic hydrophobic polymers like methacrylates with synthetic hydrophilic polymer like poly (ethylene oxide) was also used in the pre...

the objective of the present study was to design an oral controlled drug delivery system for sparingly soluble diclofenac sodium (dcl) using guar gum as triple-layer matrix tablets. matrix tablet granules containing 30% (d1), 40% (d2) or 50% (d3) of guar gum were prepared by the conventional wet granulation technique. matrix tablets of diclofenac sodium were prepared by compressing three layers...
