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

Study Overview
=================
Brief Summary
-----------------
To study Safety and efficacy of Tadalafil vs. Tadalafil with Sildosin in the management of moderately and severely symptomatic patients of prostatic hyperplasia

Detailed Description
-----------------
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.
