  High performance liquid chromatography with ultraviolet detection (HPLC-UV) was developed and validated for quantification of allopurinol and its active metabolite oxypurinol; in dog plasma with naturally acquired zoonotic visceral leishmaniasis. Allopurinol is a potent inhibitor of the xanthine oxidase enzyme; an enzyme that catalyzes the conversion of hypoxanthine to xanthine and from xanthine to uric acid. In veterinary medicine allopurinol is indicated in the treatment of canine visceral leishmaniasis. Allopurinol is utilized to inhibit the synthesis of Leishmania RNA. The conditions defined for development of the chromatographic analysis of dog plasma samples by utilizing the mobile phase of the HPLC-UV consist of a mixture of 0.1% water, 88% formic acid and 0.25% acetonitrile. Allopurinol and oxypurinol were separated on a LiChroCART® 125-4 LiChrospher®.. View More»
