Use of Rutin for Successful Management of Feline Idiopathic Chylothorax

Abstract

High-dose of rutin (500 mg, TID, PO) was used for medical management of a case of feline idiopathic chylothorax. The amount of pleural effusion decreased after the initial treatment. Daily doses of rutin were increased from 1500 to 2000 mg at day 29 of treatment. ~150 days later, no pleural effusion was observed and after ~450 days, rutin therapy was discontinued. Two years after the initial presentation, the cat was free of clinical signs and pleural effusion. This suggests that high dose rutin may be clinically useful for the treatment of feline idiopathic chylothorax.
