Are alpha-blockers involved in lower urinary tract dysfunction in multiple system atrophy? A comparison of prazosin and moxisylyte.

Lower urinary tract dysfunction is a major cause of morbidity in patients with multiple system atrophy (MSA). alpha1-Adrenergic receptors are present in the proximal urethra where impaired relaxation may be responsible for voiding difficulty and a large amount of residual urine. An open study was designed to evaluate whether the blockade of these receptors by prazosin (a nonselective alpha1 blocker) and moxisylyte (an alpha1A-selective blocker) would improve bladder emptying in patients with MSA. Post-micturition residual volumes and clinical symptoms of 49 patients with MSA were evaluated at trial entry and after 4 weeks (prazosin; n=21 and moxisylyte; n=28). The respective means for the prazosin and moxisylyte groups were 38.1% and 35.2% reductions in residual urine volume (P<0.05), and there was lessening of urinary symptoms. Side effects due to orthostatic hypotension were seen in 23.8% of the prazosin group but in only 10.7% of the moxisylyte group. These effects were common in patients with postural hypotension of more than -30 mmHg at trial entry (P<0.05). Modulation of alpha1-receptors may function in the management of lower urinary tract dysfunction in MSA.[1]
