lidocaine + osmic acid + prednisolone

This is a combination drug containing three active ingredients: lidocaine, osmic acid, and prednisolone. Lidocaine is a local anesthetic that blocks sodium channels in neurons to prevent pain signal transmission[1]. Prednisolone is a synthetic corticosteroid with anti-inflammatory and immunosuppressive effects, acting by binding to the glucocorticoid receptor and modulating gene expression[3]. Osmic acid (osmium tetroxide) is not commonly used as a pharmaceutical agent but has been historically used for its sclerosing properties in certain medical procedures; however, it is not typically included in standard pharmaceutical combinations for pain or inflammation. The combination of these agents would theoretically provide both local anesthesia (lidocaine) and anti-inflammatory action (prednisolone), with possible additional tissue effects from osmic acid.
