Abstract

Purpose

To compare the efficacy and the safety of Tamsulosin 0.4 mg/day and 0.8 mg/day in patients suffering from lower urinary tract symptoms due to benign prostatic obstruction.

Patients and Methods

A prospective interventional, double-blinded, controlled study was carried out on 93 patients who met the criteria and divided randomly into two groups: group A for Tamsulosin 0.4 mg/day and group B for Tamsulosin 0.8 mg/day. International prostate symptom score, post void residual urine volume, and maximum flow rate of urine were assessed before and after 4 weeks of treatment.

Results

Both study groups showed a significant reduction in storage sub-score but only frequency was significantly reduced in group B (P < 0.001). On the other hand, Tamsulosin 0.8 mg was superior to Tamsulosin 0.4 mg regarding voiding sub-score except for straining (P = 0.325). Accordingly, the total international prostate symptom score was significantly improved in group B versus group A (P < 0.001). Furthermore, maximum flow rate and post-void residual urine volume were notably improved in Group B as compared to Group A (P < 0.001). Of all adverse events only dizziness was noted to be statistically significant in Group B versus Group A (P < 0.001).

Conclusion

Tamsulosin 0.8 mg has shown better outcomes in treating patients who suffer from lower urinary tract symptoms due to benign prostatic enlargement than Tamsulosin 0.4 mg, and besides that, it is well tolerated.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
