Non-steroidal anti-inflammatory drugs and renal response to exercise: a comparison of indomethacin and nabumetone.
Nabumetone , a newer non-steroidal anti-inflammatory drug ( NSAID ) which preferentially blocks cyclo-oxygenase-2 activity , may be less nephrotoxic than indomethacin . This study tested whether nabumetone has effects different from those of indomethacin on exercise-induced changes in renal function and the renin-aldosterone system . In a r and omized fashion , ten subjects were studied after indomethacin ( 100 mg ) , nabumetone ( 1 g ) or no medication  ( control ) administered orally at 22.00 hours on the day before each study day , and again at 8.00 hours upon arrival at the laboratory . Renal function was studied at baseline , during grade d 20-min exercise sessions at 25 % , 50 % and 75 % of the maximal oxygen uptake rate , and subsequently during two 1-h recovery periods . Heart rate , arterial blood pressure , cardiac output and plasma catecholamines at rest and during exercise were not altered by indomethacin or nabumetone . Indomethacin decreased urinary rates of excretion of 6-oxo-prostagl and in F(1alpha ) ( 6-oxo-PGF(1alpha ) ) and thromboxane B(2 ) in all study periods . Nabumetone decreased 6-oxo-PGF(1alpha ) excretion during and after exercise . Excretion rates for PGE(2 ) did not change . Neither indomethacin nor nabumetone changed baseline values or exercise-induced decreases in renal plasma flow or glomerular filtration rate . Indomethacin , but not nabumetone , decreased sodium excretion , urine flow rate and free water clearance . The renal response to exercise , however , remained unchanged . In contrast with nabumatone , indomethacin decreased the plasma renin concentration . Thus , during exercise , nabumetone may decrease the excretion of 6-oxo-PGF(1alpha ) by inhibition of cyclo-oxygenase-1 or by inhibition of specific exercise-induced activation of cyclo-oxygenase-2 , or both . None of the drugs changed the renal response to exercise . Inhibition by indomethacin of angiotensin II and thromboxane A(2 ) synthesis may , during exercise , counterbalance renal vasoconstriction caused by blockade of vasodilatory prostagl and ins
