The present study was undertaken to design and evaluate bilayer tablets of ciprofloxacin hydrochloride containing an immediate release layer and a mucoadhesive extended release layer. Tablets were prepared by direct compression method using Carbopol 934P, Hydroxylpropyl methylcellulose -15 cps (HPMC-15cps), Methocel K4M and Sodium Carboxy methylcellulose (Na-CMC) as mucoadhesive polymer. All the formulations showed uniform weight, thickness, crushing strength and content uniformity. Tablets were evaluated by mucoadhesive strength, ex-vivo residence time and in vitro drug release profile. Methocel K4M, HPLC-15 cps and Carbopol 934P based formulation (F-3, F-2 and F-1) showed maximum mucoadhesive strength (74.5 gm to 61.81 gm). Ex vivo residence time was 8.5 hr for F-3 and 6.75 hr for F-1. Time required for 100% drug release from F-1, F-2, F-3 and F-4 were 5 hr, 3 hr, 7 hr and 3 hr respectively. Release profile was compared with a commercial ciprofloxacin tablet. Higher sustained drug release was found in all formulations than the commercial product.

Abstract


The present study was undertaken to design and evaluate bilayer tablets of ciprofloxacin hydrochloride containing an immediate release layer and a mucoadhesive extended release layer. Tablets were prepared by direct compression method using Carbopol 934P, Hydroxylpropyl methylcellulose -15 cps (HPMC-15cps), Methocel K4M and Sodium Carboxy methylcellulose (Na-CMC) as mucoadhesive polymer. All the formulations showed uniform weight, thickness, crushing strength and content uniformity. Tablets were evaluated by mucoadhesive strength, ex-vivo residence time and in vitro drug release profile. Methocel K4M, HPLC-15 cps and Carbopol 934P based formulation (F-3, F-2 and F-1) showed maximum mucoadhesive strength (74.5 gm to 61.81 gm). Ex vivo residence time was 8.5 hr for F-3 and 6.75 hr for F-1. Time required for 100% drug release from F-1, F-2, F-3 and F-4 were 5 hr, 3 hr, 7 hr and 3 hr respectively. Release profile was compared with a commercial ciprofloxacin tablet. Higher sustained drug release was found in all formulations than the commercial product.
