Xanthine oxidase inhibitors have found to play a role in oxidative damage. Doxorubicin induces dilated cardiomyopathy via oxidative damage. Thus we hypothesize that febuxostat helps in remediation of doxorubicin-induced cardiomyopathy.
For 14 days male Albino Wistar rats, doxorubicin with febuxostat (10mg/kg/day oral), doxorubicin with carvedilol (30mg/kg/day oral), doxorubicin (2.5mg/kg/day for 6 total doses on alternate days) and control (normal saline 2.5ml/kg/day i.p. for 6 total doses on alternate days) was administered in the above four respective groups.
In the doxorubicin with febuxostat group, biochemical, hemodynamic and histological markers evidentially had a protective role in doxorubicin-induced cardiomyopathy. Febuxostat decreased caspase-3 and Bax, increased Bcl-2 and was TUNEL positive. Creatine kinase- MB (CKMB) and brain natriuretic peptide (BNP) levels reduced in the group treated with Febuxostat.
Febuxostat prevents oxidative stress and defends cardiac myocytes against doxorubicin-induced cardiomyopathy.
