[Efficacy and safety of azosemide in patients with edema and ascites].

OBJECTIVE

To assess the efficacy and safety of azosemide in patients with edema and ascites.

METHODS

A multicentral, randomized, double-blind, controlled clinical trial was applied. All 223 patients (cardiac edema 92, hepatogenic edema 63, renal edema 68) were randomized to azoesmide and furosemide group, and all patients were treated for 2 weeks. Patients with cardiac or renal edema took azosemide (30 mg/d) or furosemide (20 mg/d); patients with hepatogenic edema took azosemide (60 mg/d) or furosemide (40 mg/d). The dosage were adjusted to azosemide 60 mg/d (cardiac, renal edema), 90 mg (hepatogeic edema); or furosemide 40 mg/d (cardiac, renal edema), 60 mg (hepatogeic edema), if diuretic effects were not obtained at the end of third day.

RESULTS

At the end of the study, the weight changes were (2.87+/-3.10) kg and (2.81 +/-2.84) kg; the total effective rate of edema lessen was 89.19% and 89.81%; the total effective rate of heart function improvement was 64.44% and 66.66%; the 24 h urine output increased (321.85 +/-669.52) ml and (273.80 +/-645.72) ml for azosemide and furosemide, respectively. The total effective rate of ascites lessen (tested by B-ultrasound) was 89.28% and 86.66%; abdominal girth decreased (5.20 +/-3.58) cm and (5.03 +/-3.74) cm for azosemide and furosemide, respectively. The adverse event rate was 23.01% in azosemide group and 21.01% in furosemide group; the main adverse effects were hypokalemia, hyperuricemia, hypertriglyceridemia and thirsty.

CONCLUSIONS

Azosemide could effectively lessen edema, improve heart function and decrease ascitesûit is well tolerated and is particularly useful for the diuretic treatment.
