Effect of phenylpropanolamine on incontinence in children with neurogenic bladders. A double-blind crossover study.
In children with myelodysplasia and a low-level spinal cord lesion (low lumbar-sacral), detrusor hyperactivity together with dyssynergic urethral function forms the main pathophysiological basis for incontinence. Pharmacological treatment of incontinence due to neurogenic bladder dysfunction has been tried, mainly with anticholinergics and alpha-adrenoceptor antagonists. In this study, the effects of the alpha-adrenoceptor agonist phenylpropanolamine on urodynamic parameters and incontinence were investigated in 10 patients. Effects on incontinence were evaluated in a double-blind crossover trial. Plasma concentrations of phenylpropanolamine were measured by means of gas chromatography-mass spectrometry. Phenylpropanolamine reduced detrusor hyperactivity and improved continence, but the effect was not so pronounced as to make the patients continent.
