BACKGROUND: The prevalence of overactive bladder (OAB) appears to increase with age (aging), and free radicals most contribute to an increase in the aging process. But now, some researchers have found the efficacy of Morinda citrifolia in inhibiting the oxidative stress process so that it is expected to be beneficial for the treatment of OAB. AIM: The aim of this study was to find out the effect of M. citrifolia extract on overactive women bladder (OAB) through observation of high-sensitivity C-reactive protein (hs-CRP) urine level. METHODS: This research is an experimental study using double-blind randomized controlled trial design conducted at General Hospital H. Adam Malik Medan, USU Pharmacy Laboratory for extraction of noni fruit (M. citrifolia) and the Integrated Laboratory of Biochemical-Biomolecular USU Faculty of Medicine for the examination of hs-CRP urine levels. A t-dependent test is performed if data distribution is normally distributed or if not normally distributed, the median values are compared with the Mann–Whitney U-test. The effect of noni in hs-CRP levels performed by wilcoxon signed-Ranks Test. The statistical significance test with CI 95% and significant difference value p<0,05. RESULTS: These results indicate that the noni fruit extract has weak antioxidant activity (IC50 >150 ppm). From the statistical analysis, a significant difference (p < 0.05) was obtained in hs-CRP urine level after compared to before treatment. These results indicate that after treatment, there was an improvement in the degree of OAB symptom scores in Group A and Group B. CONCLUSIONS: Noni fruit extract (M. citrifolia) is proven to be able to inhibit oxidative stress in urothelium through observation of hs-CRP urine levels in overactive women bladder (OAB).
