What mechanism do corticosteroids employ to alleviate symptoms like nausea during chemotherapy?

Corticosteroids play a significant role in managing symptoms associated with chemotherapy, such as nausea, primarily through their anti-inflammatory properties. They help to decrease inflammation, which can contribute to the development of nausea and overall discomfort during treatment. By reducing the inflammatory response, corticosteroids can help stabilize the mood of the patient's gastrointestinal tract and modulate the body’s response to chemotherapy agents, leading to decreased nausea and vomiting.

The effectiveness of corticosteroids in this context is well-documented, as they are often employed in combination therapy to enhance antiemetic effects alongside other medications. Their ability to act on multiple pathways, including hormonal and immune responses, further supports their role in alleviating these distressing symptoms for patients undergoing chemotherapy.
