Outcome of Modification of Dose and Time of Administration of Tamsulosin in Men with Abnormal Ejaculation

Abstract

Introduction: Alpha-adrenergic blockers are now the cornerstone medication in management of lower urinary tract symptom (LUTS); however, the associated treatment-related abnormal ejaculation could be a bothersome event. This is a comparative study among different methods of tamsulosin administration in terms of efficacy, recoverability of ejaculatory function, and quality of life (QoL) in men with tamsulosin-related abnormal ejaculation. Patients and Methods: Sexually active men receiving tamsulosin for LUTS who were bothered by treatment-related abnormal ejaculation following initiation of tamsulosin were randomized into 3 groups; group A received intermittent-full-standard-dose, group B received low-dose-tamsulosin, and group C received full-standard-dose tamsulosin The status of ejaculatory function, IPSS, QoL score, and Q-Max were measured at baseline and 3 months later. Results: A total of 93 men with mean age of 53.1 years were included in the study, 3-months after randomization, statistically significant improvements in IPSS, QoL index, and Q-Max in comparison to pre-treatment levels were noted. Restoration of normal ejaculation was reported by 74.1 and 90.3% of patients in group A and B, respectively, versus none in group C. The QoL score was significant when comparing group A to the other groups; finally, the Q-Max was significant when comparing group C to the other groups. Conclusion: For patients bothered by tamsulosin-related abnormal ejaculation, a significant improvement in the QoL, without deviation from the therapeutic purpose of treatment, can be achieved by administration of 0.4 mg tamsulosin every other day.
