The developed method was successfully implemented in the estimation of curcumin and piperine

encapsulated in Eudragit E 100 nanoparticles and this method is also suitable for use in routine analysis of curcumin and piperine in active pharmaceutical ingredient and in pharmaceutical dosage forms. All authors have none to declare. “
“Oral administration is still a common convenient method for introducing Torin 1 in vitro drugs in to the systemic circulation and because of ease of administration and low cost therapy leads to higher levels of patient compliance.1 However, this approach is not has been suited to a variety of active pharmaceutical ingredients (API) which are of having a narrow therapeutic absorption window in the upper GIT (gastro intestinal tract). This is due to short transit time of the selected dosage form in the segments of upper GIT leads to lesser bioavailability. It was suggested that

novel drug deliveries like gastro retentive dosage forms like oral hydrogels were the recent advances for delivering the drug molecules to the upper gastro intestinal tract for prolonging the drug release and to improve the absorption.2 BIBW2992 molecular weight The development of oral hydrogels was formulated with an aim to hold the dosage form in the gastric environment.3 These drug delivery systems maintain its uniformity throughout the stomach and swells up rapidly in the stomach environment for a controlled drug release.4 Hydrogel is a three dimensional polymeric network of hydrophilic chains which are cross-linked either through physical or chemical bonding. next Hydrogel absorbs water to swell in the presence of surplus water because of the hydrophilic nature of polymeric chains. Cefditoren Pivoxil (CP) is a semi synthetic, third generation cephalosporin exhibiting bactericidal action by inhibiting

cell wall synthesis.5 Cefditoren Pivoxil is a prodrug which can be hydrolyzed by esterase during absorption to Cefditoren as an active drug and is distributed in the blood circulation. Cefditoren is used for the treatment of uncomplicated skin and structure skin infections. CP has a broad spectrum of activity against Gram negative and Gram positive bacterial infections including strains of Staphylococcus pyrogenes, Haemophilus influenza, Klebsiella pneumonia and Staphylococcus aureus. 6 CP is the most frequently used drug for the treatment of tonsillitis, pharyngitis and acute exacerbations of chronic bronchitis. 7 The present research was mainly focused to formulate the swellable hydrogel matrix formulations for controlled drug delivery and to study the drug release pattern of Cefditoren Pivoxil. Further the pre-compression and post compression parameters were evaluated. The swelling index and stability studies were also performed.8 Cefditoren Pivoxil (CP) was obtained as a gift sample from Hetero drugs (Hyderabad, India), Carbopol 940 and sodium alginate was procured from Pure Chem Laboratory.
