Safety and Efficacy of Tadalafil vs. Tadalafil With Sildosin in the Management of Moderately and Severely Symptomatic Patients of Prostatic Hyperplasia

Overview

To study Safety and efficacy of Tadalafil vs. Tadalafil with Sildosin in the management of moderately and severely symptomatic patients of prostatic hyperplasia

Introduction Benign prostatic hyperplasia (BPH) is a common cause of lower urinary tract symptoms (LUTS) in middle-aged and elderly men, and the incidence rate of LUTS associated with BPH (LUTS/BPH) increases with age. LUTS can be broadly grouped into: (i) storage symptoms, such as frequency, urgency, and nocturia (ii) voiding symptoms, such as intermittency, weak stream and straining, and (iii) post-micturition symptoms, such as a feeling of incomplete emptying and post micturition dribble. For optimal management of LUTS/BPH, medications should be chosen based on age, disease progression, need for long-term management, and other clinical parameters. Alpha 1 adreno-receptors antagonists (alpha 1 blockers) are proposed as first-line drug therapy for LUTS/BPH as these agents reduce the adrenergic tone of the smooth muscle within the prostate and bladder neck, thereby relieving the bladder outlet obstruction. Tadalafil (phosphodiesterase type 5 \[PDE-5\] inhibitor) was approved for treating LUTS/BPH. The inhibition of PDE-5leads to accumulation of cyclic guanosine monophosphate in the smooth muscles of the prostate and urethra which causes their relaxation resulting in alleviation of the symptoms of LUTS/BPH.
