The objective of research is to develop a mucoadhesive in-situ nasal gel formulation of xylometazoline hydrochloride for the treatment of allergic rhinitis to avoid possible side effects. Mucoadhesive in-situ nasal gel of xylometazoline hydrochloride was formulated by ionic gelation method using xanthan gum as ionsensitive agent and different grades of HPMC as a viscosifying agent. The prepared batches were evaluated for drug content, pH, gelling time, spreadability, gelling strength, mucoadhesive strength and in-vitro drug release. In vitro drug release study was carried by using diffusion cell with dialysis membrane. Short term stability study was also performed for final formulation as per ICH guidelines. The drug content and pH of the formulation were found to be satisfactory. The mucoadhesive strength of the formulation was found to be from 212.55 gm/cm2 to 490.8 gm/cm2. The viscosity and spredability of the formulations were found to be satisfactory. Amongst all these formulations, the maximum drug release was found to be 81.46 % in formulation F8 containing 0.2 % xanthan gum and 0.5 % HPMC K15M . The developed formulations showed sustained release of drug up to 8 hrs and found to be stable. |
