Which of the following drugs is included in prophylactic antiemetic regimens to prevent delayed CINV?

A. Fosaprepitant

B. Ondansetron

C. Prochlorperazine

D. Dexamethasone

Answer: D

Option A: Incorrect. Although fosaprepitant has a long half-life, it is used to prevent CINV within the acute setting.

Option B: Incorrect. Ondansetron has a short half-life and is dosed at least twice or three times daily in the prevention of CINV in the acute setting. The 5HT3-antagonists as a class are not used to prevent CINV in the delayed setting.

Option C: Incorrect. Phenothiazines such as prochlorperazine have a short half-life and are used in the prevention of CINV in the acute setting as well as during the active phase of acute nausea or vomiting. They are not useful in the delayed setting.

Option D: Correct. Dexamethasone has been shown to prevent CINV in the delayed setting after chemotherapy administration. Dexamethasone is also not useful in the treatment of the active nausea or vomiting.
