cyclophosphamide + dexamethasone + sulfasalazine

This is a combination regimen consisting of three drugs—cyclophosphamide, dexamethasone, and sulfasalazine—each with distinct mechanisms of action. Cyclophosphamide is an alkylating agent used primarily as an antineoplastic and immunosuppressive drug; it interferes with DNA replication and cell division, leading to cytotoxic effects on rapidly dividing cells. Dexamethasone is a synthetic glucocorticoid corticosteroid that exerts potent anti-inflammatory and immunosuppressive effects by modulating gene expression through the glucocorticoid receptor. Sulfasalazine is a disease-modifying antirheumatic drug (DMARD) with anti-inflammatory properties; it is metabolized into active components that reduce inflammation in conditions such as rheumatoid arthritis and inflammatory bowel disease. While all three drugs are individually approved for various indications (e.g., cancer, autoimmune diseases), this specific triple combination does not have a unique brand name or established fixed-dose formulation but may be used off-label in complex autoimmune or inflammatory conditions where multiple pathways need to be targeted.
