Short-term, high-dose muzolimine treatment in patients with chronic renal failure and acute fluid retention.
Muzolimine, the new sulphonamide-free loop-diuretic with both high ceiling and long-lasting activities, was tested in 21 adult patients with chronic renal failure (CRF) (creatinine clearance ranging from 30 to 5 ml/min) and acute fluid overload. Low-protein diet and individual drug therapy were unchanged throughout the study. All patients received a single oral dose of 240 mg of muzolimine for 4 or 6 consecutive days depending on individual response. Clinical status, diuresis, body weight, blood and urine chemistry were recorded daily. In 19 out of 21 patients muzolimine treatment induced reversal of edema and congestive heart failure and a satisfactory fluid balance was achieved. Only two patients did not respond to diuretic treatment and required dialysis to control fluid balance and azotemia. In responsive patients diuresis increased by 50-100% and no rebound antidiuresis was observed after drug withdrawal. Body weight decreased meanly by 9%. No significant change occurred in serum concentration of K throughout the study, even in the 11 patients on digoxin. Except for a slight decrease of serum Cl by the end of treatment, no significant change in serum electrolytes was recorded. No effect was observed on blood glucose, urea and creatinine clearance whereas a slight increase of serum uric acid was recorded. Urinary lysozyme and gamma-GT were similar before and after the trial. Apart from a single case of muscle cramps, no significant side-effects were recorded. In conclusion, the present results indicate that short-term, high-dose oral muzolimine treatment is effective and safe in most patients with advanced CRF and acute fluid retention.
