 note = {Background:Amantadine is a drug used for patients with Parkinson's disease (PD) and vascular parkinsonism (VP). These patients often have lower urinary tract symptoms (LUTS) and nocturnal polyuria (NP). Thus, we investigated the effect of amantadine on these in parkinsonian patients.Methods:Twenty-two patients with LUTS, including 13 with PD and nine with VP, were recruited. We performed a urinary questionnaire, frequency-volume chart, and residual urine (RU) measurement before and after daily administration of 150 mg and 300 mg amantadine.Results:Before amantadine administration, mean daytime urinary frequency was 9.07(standard error [SE], 0.64), nighttime urinary frequency 2.89 (0.24), urinary urgency per week 24.2 (6.69), urge incontinence per month 15.1( 9.94), urine volume per void 145.6( 12.6) mL, and residual urine volume 12.5( 6.30) mL. After daily 150 mg amantadine administration, mean daytime and nighttime urinary frequency, urinary urgency, and urge incontinence decreased to 6.9( 0.42), 1.97( 0.21), 13.0( 3.58), and 14.2( 10.2), respectively, and urine volume per void increased to 174.1( 11.3) mL. NP( N=8) was ameliorated in six patients. No patient had side effects. After daily 300 mg amantadine administration( N=8), mean daytime and nighttimeurinary frequency, urinary urgency, and urge incontinence decreased to 6.90 (0.33), 1.69 (0.10), 5.88 (1.61), and 2.31 (0.61), respectively, and urine volume per void increased to180.2 (15.0) mL. NP (N=4) was ameliorated in two patients. One patient developed hallucination, and two patients developed flashing sensation.Conclusion:Amantadine has beneficial effects on LUTS and NP in patients with VP and PD., Original},
