Design, Development and Characterization of Gastroretentive Floating Tablet of Levofloxacin using Natural Polymer Peanut Husk
Abstract
In the present study, levofloxacin gastroretentive floating tablet (GRFT) was formulated using peanut husk powder as a natural release modifier for providing sustained drug delivery at the stomach to effectively treat infections. Preformulation studies such as UV analysis and drug excipients study using Fourier-transform infrared (FTIR) were performed. Peanut husk powder was prepared by crushing and grinding the dried peanut husk. The GRFT formulations (GRFT1- GRFT9) were formulated using the direct compression method with varied concentrations having peanut husk powder, HPMCK4M and carbapol 934, along with other ingredients. Formulations were characterized based on the pre-compressional parameter and post-compressional parameters. The results for GRFT5 were found to be best among all batches as it showed sustained %drug release of 89.52 ± 0.3% upto 12 hours and it revealed enhanced therapeutic performance of the drug. However, in-vivo study needs to be performed for a better comparison of data with in-vitro results.
