Shikonin nasal spray film preparation promoted the repair of nasal mucosal injury by the interaction of shikonin with interleukin-6.

Introduction: Nasal spray films, an innovative formulation in recent years, have garnered significant acclaim from patients with nasal mucosal injury because it integrate the benefits of spray and film formulation, offering ease of application while reducing the risk of droplet formation and further inhalation into the throat. Furthermore, Lithospermum erythrorhizon is a traditional Chinese medicine frequently employed in the management of dermal injuries, and our previous work suggested its major compound, shikonin, possesses the capacity to promote the repair of nasal mucosal injury. Notwithstanding these encouraging results, research on the development of shikonin nasal spray film preparation (SNSF) and its bioactivity mechanism remains limited.
