Large study (283 women) on the effectiveness of Manosar®: 2 g of d-mannose + 140 mg of proanthocyanidins (PAC), of prolonged release

To compare the efficacy and safety in the prophylasis of urinary tract infections (UTIs) with a food supplement that contains D-mannose like active ingredient (Manosar®), in comparison to another preparation in which the active ingredient are the proanthocyanidins (PAC), both of them, in prolonged released, after, they was administered for 24 weeks. A multicenter, randomized and double blind experimental study was carried out. 283 women with a history of recurrent UTIs without evidence of complication were included. They were randomized 1: 1 in two groups. In one group, 1 oral sachet of Manosar® a day was administered, and in the other group 1 oral sachet of a compound of 240 mg of continuous-release PAC. Prior to inclusion in the study, the episode of UTI was confirmed at least by the clinical symptoms and positivity of the Combur test. Valid data were obtained from 184 patients with an average age of 49.5 years: 90 received Manosar® and 94 isolated PAC. A total of 72 patients suffered an UTI due to E.coli: 25 patients in the arm with Manosar® versus 47 patients in the isolated PAC group, this difference being statistically significant (p=0.002). The free time of new UTI recurrences was 98.6 days in the group treated with Manosar® and 84.6 days in the group with isolated PAC. The oral taking of a daily sachet of Manosar® is effective and safe in preventing recurrent UTIs in women, being superior to the oral taking of isolated PAC.
