Abstract
Background/Aims: Indomethacin has been shown to have adverse effects on renal function in patients with well-compensated alcoholic cirrhosis. The aim of this study was to determine whether an oral prostaglandin E 1 analogue, misoprostol, could prevent this indomethacin-induced renal dysfunction. Methods: Six patients with well-compensated alcoholic cirrhosis were studied. Renal hemodynamics and tubular function were assessed by clerance techniques before and after an oral dose of (i) 50 mg of indomethacin alone (I 50), and (ii) a combination of I 50 and 200 μg of misoprostol. Results: I 50 produced a significant reduction in glomerular filtration rate, a fall in effective renal plasma flow and an increase in renal vascular resistance. Two hundred micrograms of misoprostol was able to abolish the deleterious renal effects of indomethacin totally, yielding an increase in glomerular filtration rate and effective renal plasma flow and a decrease in renal vascular resistance as well as an increase in urinary volume and urinary sodium excretion. These beneficial effects were maximal in the hour immediately following medication, but were only transient, and this may be a limiting factor in its clinical use. Conclusions: If the beneficial renal effects of misoprostol could be confirmed after chronic administration, then the vasodilatory, natriuretic and diuretic potential of 200 μg of misoprostol could be of potential therapeutic value in patients with well-compensated alcoholic cirrhosis who require non-steroidal anti-inflammatory drug therapy.
