METHODS
A secondary analysis was conducted with data from a randomized, controlled, double-blind trial comparing a fixed combination of extracts of restharrow root, Java tea, and goldenrod herb (Aqualibra®) to placebo in 200 women with acute lower uUTI. Symptom scores reported in the original trial were reanalyzed and adjusted to the definitions of the Acute Cystitis Symptom Score (ACSS).RESULTS
Based on a subgroup of patients with evaluable microbiologic data (n = 122), the decrease of the mean sum-score of three typical ACSS-adjusted symptoms showed significant superiority of the herbal preparation over placebo already after one day of treatment (p = 0.0086); on Day 7, the average difference was -1.9 score points (p < 0.0001). The superior efficacy of the herbal preparation on Day 1 was mainly driven by a difference in response rates of the symptom 'dysuria' (group difference: -29.4%, p = 0.0042). Furthermore, significantly fewer patients in the verum group required antibiotic therapy (15.3% vs. 49.2%, p = 0.0001). These results were confirmed in the intention-to-treat (ITT) population (n = 200).
