The cephalosporin antibiotic cefuroxime axetil is a prodrug primarily absorbed from the upper part of the GIT and degraded in presence of intestinal esterases. The purpose of this investigation was to apply Box behnken response surface methodology for the development of a gastro retentive floating tablets of cefuroxime axetil and to inspect the effect of formulation variables on drug release and the buoyancy properties of the delivery system.
The amount of methocel K4M, cetyl alcohol and sodium bicarbonate were taken as independent variables and floating lag time, Q12h and t50% were taken as dependent variables. Tablets were prepared by the direct compression method and evaluated for physical properties, swelling, floating lag time, drug release. In vivo floating study also done on statistically optimized formulation in healthy male rabbit.
The duration of floating time were principally >24 hours and floating lag times <29 seconds. FTIR, DSC and diastereomeric ratio of the SOF revealed there was no chemical interaction between drug and polymer. The statistically optimized formulation (SOF) released drug according to zero order kinetics with a fickian diffusion mechanism. The in vivo evaluation of SOF in healthy rabbit showed that the tablet was buoyant in gastric fluid with change in its swelling.
Key words: Box behnken design (BBD), Response surface methodology, Cefuroxime axetil, Gastroretentive drug delivery, Optimization, Independent Variables, Dependent Variables.

Borrelia Burgdorferi Essay

- Borrelia Burgdorferi Life History: Lyme disease is an infection caused by Borrelia burgdorferi, a spirochete that is found in deer ticks of genus Ixodes. Lyme disease was named in 1977 after arthritis was observed in clusters in children in Lyme, Connecticut. An infected tick can transmit B. burgdorferi to the humans and animals that it bites. If left untreated, the B. burgdorferi can cause a systemic infection by traveling through the bloodstream and establishing itself in various body tissues....   [tags: Medical Health Biology Essays]

Essay on Preventing Postoperative Infections in Contaract Surgery

- DISCUSSION In the wake of concerns about increasing rates of postoperative endophthalmitis and antibiotic resistance, continuing efforts are made to find the most effective prophylactic method for preventing postoperative infections. Despite this, endophthalmitis continues to be one of the most devastating complications of cataract surgery. Several factors are suggested to be involved in this process, such as the surgical technique, the intraoperative contamination of the anterior chamber and the increasing age of patients undergoing phacoemulsification....   [tags: technique, patients, infections]

Essay on Use Of Fluid Resuscitation Following Trauma

- Crystalloid versus Colloids: Optimizing Fluid Resuscitation Following Trauma Blunt force trauma to the chest cavity can cause tremendous structural damage, resulting in compromised functional integrity to essential organs, such as the heart and the lungs. Because these primary organs facilitate perfusion to the rest of the body, damage can result in massive hypoperfusion leading to shock. Many researchers concur on the subject of fluid resuscitation to abate affects of cardiogenic shock and even death; however, the debate arises when considering types of fluid resuscitative therapy....   [tags: Heart, Cardiology, Cardiac tamponade, Blood]
