Muzolimine in chronic renal failure: a study in 16 patients.
Muzolimine is a diuretic with chemical features different from all other known diuretics, and its use seem to be particularly interesting in patients with chronic renal failure. In fact, similarly to furosemide, muzolimine presents a strong action on Henle's loop but with a slower and more lasting effect, as experimentally demonstrated in both animals and man. We used high doses muzolimine (240, 480, 720 mg/die) in 16 patients with chronic renal failure (creatinine clearance less than 20 ml/min) and clinical pattern of important hydrosaline retention (6 primitive glomerulonephritis, 3 interstitial nephrites, 1 vascular nephropathy, 1 diabetic nephropathy, 1 lupus nephritis, 1 amyloidosis, 1 polycystic nephropathy and 2 nephropathies of unknown diagnosis). Muzolimine diuretic action was compared with furosemide 500 mg/die. The schedule employed was: furosemide 500 mg/die for 5 days followed by 6 days of muzolimine treatment at increasing doses (240 mg on 1st and 2nd day, 480 mg on 3rd and 4th, 720 mg on 5th and 6th). In all patients (undergoing a diet constant in water, sodium, potassium and protein content) body weight, blood pressure, heart rate, serum and urinary electrolyte concentration, serum and urinary uric acid, BUN, creatinine clearance, glycaemia, hematocrit and hemoglobin were daily controlled. A clinical and laboratory investigation of the possible side effects was also assessed; in particular liver enzymes, bilirubin and total serum proteins were considered. In our study muzolimine increased the renal excretion of water, sodium and chloride in all cases. This effect is more evident during the treatment with the highest dose (720 mg/die) but already appears with the 480 mg/die dose and is higher than that obtained with comparable doses of furosemide.(ABSTRACT TRUNCATED AT 250 WORDS)
