 What is UROREC?

NEW Urorec Pack+caps-2

 

 

UROREC (silodosin) is a highly selective α1A receptor blocker indicated for the relief of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia in adult men alleviating a range of BPH symptoms.1,2

Why choose UROREC?

UROREC has the highest selectivity for α1A receptors located in the prostate and bladder.
It is 162 x more selective for α1A receptors than for α1B so it works where you need it.1,2†

†In vitro data does not necessarily predict human clinical effects

Minimal cardiovascular impact2*
Bladder obstruction icon-website

Highest improvement in bladder outlet obstruction among alpha blockers3‡
Nocturia Icon-website

Improvement in nocturia4

*Minimal effect on supine blood pressure; no effect on ECG intervals or cardiac repolarisation;
orthostatic hypotension similar to placebo (more common in elderly although usually mild and resolves with continued treatment);
can be co-administered with antihypertensives while monitoring for possible adverse reactions.2

‡Based on alpha 1a/alpha 1b affinity ratio; study used indirect comparisons­.3

 

 

How does UROREC work differently from other alpha blockers?

UROREC has high affinity for the α1A adrenergic receptors in the prostate, the bladder, and the prostatic urethra. By this mechanism, it relaxes the smooth muscle in these organs, easing urinary flow and other symptoms of BPH.2

There are three known subtypes of α1 receptors: α1A, α1B and α1D

α1 Subtype

Predominant location

Physiologic function

α1A

 Chart-main webpage1

α1A regulates smooth muscle tone in the bladder neck, prostate, and prostatic urethra2,5

Blockade of α1A receptors relieves LUTS via relaxation of the lower urinary tract5

α1B

 Chart-main webpage2

α1B regulates vascular smooth muscle5

Blockade of α1B receptors can cause orthostatic hypotension5

α1D

 Chart-main webpage3-1

α1D is found in the central nervous system6 and the coronary arteries5

Blockade of the α1D receptor may mediate coronary vasodilation5

UROREC provides effective relief of LUTS in BPH8

The efficacy of UROREC in the relief of LUTS (as measured by IPSS total score) was:

  • Superior to placebo (p<0.001)
  • Non-inferior to tamsulosin (p = NS)
