Furosemide 211-221 adenosine A1 receptor Rattus norvegicus 44-67 12922924-13 2003 This study shows that the adenosine A(1) receptor antagonist FK838 is orally active and causes potent diuresis and natriuresis and maintains glomerular filtration rate in normal or furosemide-resistant rats. Furosemide 181-191 adenosine A1 receptor Rattus norvegicus 26-49
