Comparison of cernitin pollen extract vs tadalafil therapy for refractory chronic prostatitis/chronic pelvic pain syndrome: A randomized, prospective study.
Neurourology and Urodynamics 2020 July 11
AIMS: To compare the efficacy of cernitin pollen extract (cernitin) or tadalafil for treating persistent chronic pelvic pain despite α1-blocker monotherapy in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and lower urinary tract symptoms (LUTS).
METHODS: A total of 100 patients with refractory CP/CPPS despite ongoing α1-blocker monotherapy were randomized to receive add-on therapy with either cernitin (4 capsules/day) or tadalafil (5 mg/d) for 12 weeks. At week 12, changes from baseline in the patients' CP/CPPS, LUTS, and voiding function, as assessed using the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), the International Prostate Symptom Score (IPSS), and uroflowmetry, respectively, were compared between the groups.
RESULTS: The final analysis included 42 and 45 patients in the cernitin and tadalafil groups, respectively. Although the NIH-CPSI total, NIH-CPSI pain sub-score, and NIH-CPSI quality of life sub-score significantly improved in both groups, the cernitin (vs tadalafil) group showed significantly greater improvements in the NIH-CPSI total score (-6.8 vs -4.6; P = .02) and NIH-CPSI pain sub-score (-4.1 vs -1.5; P < .001). Half (50%) of the patients in the cernitin group showed a reduction greater than 50% in their NIH-CPSI pain sub-score; in the tadalafil group, only four patients (8.9%) showed ≥50% improvement (P < .001). In contrast, the improvement in LUTS was significantly superior in the tadalafil group.
CONCLUSION: Both cernitin and tadalafil significantly ameliorated chronic pelvic pain in patients with refractory CP/CPPS. The add-on of cernitin was more effective than tadalafil for pelvic pain and discomfort.
