Currently, alpha-1 adrenergic antagonists are strongly recommended as first-line therapy for patients with moderate to severe symptoms because of their safety, efficacy and good tolerability. These agents are highly heterogeneous in terms of pharmacological selectivity for the adrenergic receptor subtypes with silodosin being the agent characterized by the highest α1A/α1B affinity ratio. This property has been proposed to confer to silodosin advantages in terms of bladder outlet obstruction improvement and lower incidence of cardiovascular side effects at the cost of a higher incidence of ejaculatory dysfunction. These aspects should be carefully taken in consideration when personalizing medical therapy for lower urinary tract symptoms related to benign prostatic obstruction.Keywords: alpha-1 adrenergic antagonists, benign prostate enlargement, lower urinary tract symptoms, bladder outlet obstruction
