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.
