Final answer:
Corticosteroids act as adjuvants in chemotherapy-induced vomiting by inhibiting the inflammatory response and reducing histamine production.
Step-by-step explanation:
Corticosteroids act as adjuvants in chemotherapy-induced vomiting. Chemotherapy drugs can cause severe nausea and vomiting as side effects. Corticosteroids, such as hydrocortisone, can be given alongside chemotherapy to help prevent or reduce these symptoms.
One way corticosteroids work is by downregulating the immune system, which helps inhibit the inflammatory response. They also reduce the production of histamine, which triggers the body's inflammatory response and can contribute to nausea and itching.
