Combination therapy with tamsulosin and solifenacin for male lower urinary tract symptoms with predominant filling symptoms: a new approach to an old problem

Abstract

Benign prostatic enlargement is the main cause of male lower urinary tract symptoms (LUTS). The distinction and quantification of voiding, storage and postmicturition symptoms help clinicians decide on a modern pharmacological therapeutic approach for male LUTS. Muscarinic receptors antagonists are now considered safe therapy in males and a fixed-dose combination of oral controlled absorbed system solifenacin and tamsulosin is advantageous compared to tamsulosin monotherapy in males with predominant storage symptoms when validated instruments such as International Prostatic Score Symptoms (IPSS) or Total Urgency Frequency Score (TUFS) are used. This combination therapy is well tolerated and maintains symptomatic improvement in the long term. Different options of managing male LUTS with predominant storage symptoms include a combination of tamsulosin and solifenacin, antimuscarinics alone – some with flexible dosing, and the beta-3 agonist mirabegron. Tailored pharmacological therapy for the particular patient is not a reality yet, but judicious use of the different alternatives could bring varied new therapeutic solutions for male LUTS including benign prostatic enlargement and benign prostatic obstruction.
