Abstract

Background: Clinacanthus nutans leaves have been used to support the treatment of urinary incontinence. Objectives: Evaluate effect of extracts of clinacanthus nutans leaves on volume and electrolytes concentration of urine. Materials and methods: 36 Swiss albino mice were orally administered distilled water, water extract, alcoholic extract of clinacanthus nutans leaves or furosemide. Urine volumn of mice was measured after 1,2,3,4,5, and 24 hours. Total 24-hour urine was analysed electrolytic concentration. Results: The urine volume of group administered clinacanthus nutans leaves extracts was increased after 5 hours (p<0.05). Urine Na+ and Cl- concentration of group administrated clinacanthus nutans leaves extracts increased significantly (p<0.05). Urine K+ concentration of group administrated alcoholic extract at the dose of 2000 mg/kg was significantly (p<0.05) lower than that of group administrated furosemide. Conclusions: CNL extracts increase the urine volume and salt excretion. Alcohol extract of clinacanthus nutans leaves at the dose of 2000 mg/kg reduced hypokalaemic than furosemide.
