Comparing the pharmacokinetics of GS-441524 after intravenous and oral administration of remdesivir in New Zealand cats with feline infectious peritonitis

The oral bioavailability of the compounded RDV used in this study is low, highly variable and appeared lower in cats with effusive disease, although this difference was not statistically significant. Given the small non-randomised sample, results should be interpreted considering study limitations. Despite the low bioavailability, survival rates in cats treated with oral RDV are comparable to published outcome studies with injectable RDV and oral GS-441524, indicating that oral RDV is a viable treatment option when GS-441524 is not available.
