Propiverine Hydrochloride as a Treatment for Fecal Incontinence.

PURPOSE: Propiverine hydrochloride (PH) is widely used for the treatment of urinary incontinence (UI) due to bladder overactivity. Moreover, the comorbidity of UI with fecal incontinence (FI) is known to be due to the relationship of both to nervous system disorders and dysfunction or weakening of the pelvic floor muscles. The aim of this single-arm prospective study was to evaluate the therapeutic value of PH for FI.

METHODS

Patients (n = 24) who were diagnosed as having both FI and UI from April 2015 to November 2016 were included in the study and administered a dosage of 10-20 mg PH every day for 1 month. The primary endpoint was to create a reduction in the frequency of FI per week. An evaluation criterion of ≥50% reduction in frequency was determined as effective. The percentage of the patients who achieved the ≥50% endpoint (responders) was also calculated.

RESULTS

The frequency of FI per week was 6.0 ± 8.2 (0.25-30) at baseline and reduced to 1.6 ± 2.1 (0-7) at the posttherapeutic state (P = 0.005). A reduction of ≥50% was seen in 14 of the patients (58.3%).

CONCLUSION

PH reduced the frequency of FI in patients with both FI and UI. This study introduces a possible therapeutic option for the pharmacological treatment of FI.
