Description: Fosaprepitant, also known as MK0517, is an antiemetic drug, administered intravenously. It is a prodrug of aprepitant. Fosaprepitant was developed by Merck & Co. and was approved. It is a prodrug of Aprepitant. It aids in the prevention of acute and delayed nausea and vomiting associated with chemotherapy treatment. Fosaprepitant is a weak inhibitor of CYP3A4, and aprepitant, the active moiety, is a substrate, inhibitor, and inducer of CYP3A4.

| Biological target: | Fosaprepitant dimeglumine (MK-0517) is a prodrug of Aprepitant (HY-10052) and is a neurokinin-1 receptor antagonist. |
| In vitro activity: | Fosaprepitant is likely to be combined and stored in the same intravenous (IV) bag with 5-HT3 antagonists and corticosteroids, therefore the in vitro compatibility of fosaprepitant with these agents and other IV diluents was assessed. Fosaprepitant (1 mg/mL in 0.9 % sodium chloride injection solution) was combined in binary or tertiary fashion with therapeutic-dose preparations of a 5-HT3 antagonist (ondansetron, granisetron, palonosetron, or tropisetron) and/or a corticosteroid (dexamethasone sodium phosphate or methylprednisolone sodium succinate). For diluent compatibility assessment, fosaprepitant was also prepared 1 mg/mL in 0.9 % sodium chloride injection solution, water for injection, or 5 % dextrose injection solution. Fosaprepitant demonstrated compatibility when combined in the same IV infusion bag with common 5-HT3 antagonists and corticosteroids for storage and IV coadministration, with the exception of palonosetron (incompatible under all experimental conditions) and tropisetron (incompatible unless combined with a corticosteroid). No incompatibility was observed between fosaprepitant and any of the 3 diluents tested. Use of fosaprepitant in combination with other antiemetics may provide a flexible option for administration of antiemetics to patients receiving moderately or highly emetogenic chemotherapy.

| In vivo activity: | The aim of this study was to test the efficacy of Neurokinin-1 Receptor (NK-1R) antagonist -Fosaprepitant- in inducing regression of established corneal neovascularization (CNV). Twenty C57BL/6 mice underwent alkali burn. Seven days later, when corneal neovessels had developed, they received Fosaprepitant 10 mg/ml, administered topically six times a day in the right eye for 10 days. In parallel, a group of 20 causticated mice was treated with normal saline, as control. A second independent experiment was also performed (n = 10/group). Finally, ten healthy mice received the same topical treatment for 10 days to evaluate Fosaprepitant safety. Topical Fosaprepitant administration induced a significant reduction of (i) CD31+ blood corneal neovessels (-27%, p = 0.0132), (ii) LYVE1+ lymphatic corneal neovessels (-31%, p = 0.0118) and (iii) CD45+ leucocyte infiltration (-36%; p = 0.0237). The second independent experiment confirmed these data. Moreover, Fosaprepitant-treated corneas showed a reduction in opacity, no impairment in corneal fluorescein staining and decreased infiltration of neutrophils (-72%, p < 0.05) and macrophages (-75%, p < 0.01). Finally, topical Fosaprepitant was not toxic to the ocular surface: no signs of conjunctivitis, opacity, perforations or corneal fluorescein staining were detected. Similarly, corneal TUJ1+ nerve density was not affected. The data suggests that NK-1R antagonists, such as Fosaprepitant, could be a new, promising therapeutic tool to inhibit CNV after this has been established.
