Abstract
The primary therapeutic indications for sumatriptan succinate (STS) include the treatment of migraine and cluster headaches. To enhance mucoadhesion, sodium carboxymethyl cellulose (SCMC) and hydroxyl propyl methyl cellulose (HPMC K15M) were used in this study to develop nasal mucoadhesive microspheres of STS. A central composite design, facilitated by Design Expert software, was employed to assess the impact of polymer concentrations on mucoadhesion, involving nine different formulations. The study’s findings indicated that the microspheres were uniformly sized and spherical and that the polymers were compatible with STS. The optimal formulation, consisting of 220.711 mg of SCMC and 150 mg of HPMC K15M, demonstrated the highest level of mucoadhesion. This combination effectively regulated the discharge of STS from the mucoadhesive microspheres and significantly improved their mucoadhesive properties. These results suggest that the strategic use of SCMC and HPMC K15M can enhance the performance of nasal mucoadhesive microspheres, ensuring a controlled release of STS and improved adhesion to mucosal surfaces. This has the potential to optimize the therapeutic efficacy of STS in treating migraine and cluster headaches.
