[Drug therapy of urethral diseases].

Abstract

AIM:

To describe drugs targeting urethra and prostate to treat dysfunctions such LUTS related to BPH, primary bladder neck obstruction (PBNO), detrusor sphincter dyssynergia (DSD) or sphincter deficiency (SD).

METHOD:

Pubmed search for efficacy, mode of action and side effects for each molecule. Additional data were searched from the French regulatory agencies web sites (HAS and ANSM).

RESULTS:

To treat LUTS related to BPH alpha-blockers (AB) and 5-alpha reductase inhibitors (5ARIs) have a clearer efficacy than plant extract. Daily Phosphodiesterase 5 inhibitors (PDE5Is) alone or in association with AB also demonstrate efficacy in this indication. AB are an option in PBNO and DSD related to multiple sclerosis. Although Botulinum toxin A derived molecules decrease urethral pressure in patient with DSD related to spinal cord injury or multiple sclerosis, efficiency remains to be demonstrated. Duloxetine a serotonin reuptake inhibitor increases urethral sphincter pressure and reduce stress urinary incontinence in women and men. Nevertheless, moderate efficacy combine with frequent side effects lead French regulation agency to reject its agreement.

CONCLUSION:

Armamenterium to treat urethral dysfunctions has recently increases. Two new therapeutic classes emerge: PDE5Is to treat LUTS related to BPH and an SRIs (Duloxetine) to treat stress urinary incontinence. Efficacy and safety evaluation of all the possible associations between drugs targeting urethra and/or bladder is needed to a subtler and more efficient pharmacologic modulation of lower urinary tract dysfunction.
