buccal mucoadhesive films have attracted great attention among mucoadhesive systems due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. the aim of the current study was to formulate the ziziphus jujuba aqueous extract as buccal bioadhesive film, which continiously releases the drug at sufficient concentration for reducing the frequency of th...

The low bioavailability (15%) and good solubility of Domperidone Maleate in acidic pH following oral administration favours development of a gastro retentive formulation. Gastroretentive floating matrix tablets of Domperidone Maleate were successfully prepared with hydrophilic polymers like HPMC K4M, HPMC K15M and HPMC K100M. From the Preformulation studies for drug excipients compatibility it ...

Buccoadhesive tablets of carvedilol were prepared using HPMC K4M, HPMC K15M and Carbopol 934 as mucoadhesive polymers. Fifteen formulations were developed with varying concentrations of polymers. Formulations of the BC or BD series were composed of HPMC K4M or HPMC K15M in ratios of 1:1 to 1:5 whereas in the BE series Carbopol 934 was used (1:0.25 to 1:1.50). The formulations were tested for in...

The objective of the present study was to develop floating microsphere of norfloxacin in order to achieve an extended retention in the upper GIT which may enhance the absorption and improve the bioavailability. The microspheres were prepared by solvent evaporation method using different ratio of hydroxyl propyl methyl cellulose (HPMC K4M, HPMC K15M) and ethyl cellulose with drug in the mixture ...

Floating matrix tablets of Cephalexin were prepared by using synthetic and natural polymers each in two different concentrations. The floating properties and in-vitro drug release properties were optimized and total 10 formulations were developed. The synthetic and natural polymers used were HPMC K4M, HPMC K15M and Guar Gum, Xanthan gum respectively. Each formulation consists of polymer in any ...

The purpose of the present investigation was to design and evaluate sustained release tablets of a poorly water soluble drug nifedipine, employing hydrophilic polymers Methocel K15M CR and Methocel K100LV CR and to select the best formulation based on pharmacokinetic studies. Direct compression method was used to prepare matrix tablets. The granules were evaluated for angle of repose, loose bul...

Sustained release tablets of Rosuvastatin were developed to prolong r e l e a s e o f time leading to an increase in drug bioavailability.Tablets are prepared by direct compression technique using polymers HPMC K15M,HPMC K50M and ethylcellulose.Tablets were evaluated for their physical characteristics viz.,hardness, thickness, friability and weight variation, drug content and floating propertie...

Plantain (Musa paradisiaca) starch,  prepared as crosslinked starch-urea (CSU), was utilized in the formulation of matrix tablets ambroxol hydrochloride. CSU synthesized by gelatinization plantain starch urea, with calcium chloride. Native and were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), chemical material properties. Ambroxol hydrochloride prepared CSU, ...
