Current treatment protocols primarily utilize 5-HT3 receptor antagonists, NK1 receptor antagonists, corticosteroids, and combination therapies to manage symptoms effectively. Ongoing research focuses on developing next-generation antiemetics with improved efficacy, fewer side effects, and longer duration of action to enhance patient quality of life during cancer therapy.
Market Size
The global CINV treatment market was valued at USD 2.11 billion in 2024 . The market is projected to decline to USD 1.87 billion by 2031 , reflecting a negative CAGR of 1.8% during the forecast period.
Market contraction is largely due to patent expirations of blockbuster antiemetic drugs and the increasing presence of generic alternatives , which exert pricing pressures. Nevertheless, the underlying demand remains strong due to the rising global cancer incidence, projected to reach 30 million cases annually by 2040 , according to the World Health Organization.
Market Dynamics
