The efficacy of Thai capsaicin in management of overactive bladder and hypersensitive bladder.

This paper has been generated to provide information on the effectiveness of capsaicin treatment among patients with overactive or hypersensitive bladder. The evaluation process required approximately 14 (overactive bladder) and 11 (hypersensitive bladder and primary detrusor instability) participants who received capsaicin intravesically. The solution consisted of capsaicin (concentration = 1 mM/L) diluted in 30 per cent ethanol solution 100 ml. All participants went through at least 1 urodynamic test 1 month before and after receiving capsaicin intravesical instillation. The capsaicin treatment for overactive and hypersensitive bladders was very effective. On the average, (overactive bladder) participants' voiding needs decreased from 16.5 +/- 4.8 times/day to 8.6 +/- 2.5 times/day, leakage from 9.7 +/- 8.1 times/day to 2.4 +/- 4.3 times/day, bladder capacity from 160.1 +/- 123.3 ml to 236.9 +/- 146.1 ml, and detrusor contraction from 71.1 +/- 29.2 cm/H2O to 57.3 +/- 27.2 cm/H2O. On average, (hypersensitive bladder and primary detrusor instability) participants' voiding needs decreased from (Day time) 19.45 +/- 17.99 times to 12.00 +/- 8.91 times/day, (Night time) 7.09 +/- 6.03 times to 4.09 +/- 3.8 times, bladder capacity from 197.40 +/- 156.06 ml to 323.45 +/- 129.46 ml, and detrusor contraction from 32.64 +/- 22.77 cm/H2O to 36.64 +/- 19.22 cm/H2O. Capsaicin efficiency was rated very high for both overactive and hypersensitive bladder and primary detrusor instability. In Thailand, it has been possible to produce capsaicin using local chili supplies, thus the price of the drug itself is very economical. When considering the efficiency and the inexpensive cost of capsaicin, this treatment would be another great alternative for overactive and hypersensitive bladder cure.

The efficacy of Thai capsaicin in the treatment of primary detrusor instability and hypersensitive bladder.

Our an objective was to study the efficacy of Capsaicin extracted from Capsaicin frutescen in treating the patients with hypersensitive bladder and primary detrusor instability. Eleven patients, 3 males and 8 females, with average age of 60.3ฑ14.3 years were treated by intravesical instillation 1 mM/L Capsaicin in 30% ethanol in an amount half of the bladder capacity for 30 minutes after instillation 2% xylocaine without adrenaline for 15 minutes three out of the 11 patients who could not tolerate the pain by this method were anesthesized with regional or general anesthesia. The results were as follow :- 1. Clinical symptoms were improved significantly, i e. the frequency was reduced from day : night = 19.45ฑ17.99 : 7.09ฑ6.30 to 12.00ฑ8.91 : 4.09ฑ3.8 at p < 0.05 and leakage almost disappeared. 2. Maximal bladder capacity increased from 197.45ฑ156.06 ml to 323.45ฑ129.46 ml which was statistically significant (p=0.009). 3. Detrusor pressure at maximal bladder capacity increased from 32.63ฑ22.76 cmH2O to 36.63ฑ19.21 cmH2O but was not statistically significant (P=0.823). 4. Voiding pressure nonsignificantly increased from 47.1ฑ6.4 cmH2O to 48.1ฑ6.6 cmH2O (p=0.959). The adverse effects found were burning pain at suprapubic area, sweating and hematuria.
