Fosaprepitant is an antiemetic medication used to prevent nausea and vomiting caused by chemotherapy. It is often administered in combination with other antiemetics to enhance efficacy. Fosaprepitant works by blocking neurokinin-1 (NK1) receptors in the brain, which are involved in the vomiting reflex. In summary, Fosaprepitant is effective in preventing chemotherapy-induced nausea and vomiting.
Fosaprepitant acts as a neurokinin-1 receptor antagonist, inhibiting the action of substance P, a neurotransmitter involved in the vomiting reflex.
