xiyanping + mannitol + methylprednisolone + immunoglobulin

A combination therapy containing **xiyanping**, **mannitol**, **methylprednisolone**, and **immunoglobulin**, used for intensive anti-inflammatory, immunomodulatory, antiviral, and supportive purposes. - **Xiyanping** is a semi-synthetic injectable preparation from *Andrographis paniculata* mainly used in China, with active components including andrographolide sulfates. It is traditionally used for its antiviral, antibacterial, anti-inflammatory, and antitoxic effects, often in the treatment of upper respiratory tract infections, viral pneumonia, and as adjuvant therapy in COVID-19[3][5][1][9][7]. - **Mannitol** is an osmotic diuretic commonly used to reduce intracranial and intraocular pressure and as a renal function diagnostic aid. - **Methylprednisolone** is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties, indicated for a broad range of autoimmune, allergic, and inflammatory disorders[2][4][6][8][10]. - **Immunoglobulin (IVIG)** is typically used for immune modulation and as replacement therapy in immune deficiencies or certain autoimmune diseases. This combination is likely employed in severe infections or immune-mediated disease states requiring management of inflammation, edema, immunosuppression, and immune support, though it does not represent a single registered product with a unique brand or formulation.
