This document discusses overactive bladder and compares the drug propiverine hydrochloride to previous anticholinergic agents for treating overactive bladder symptoms. It summarizes that propiverine has dual action as both an anticholinergic and calcium channel blocker. A clinical study of 73 patients compared propiverine to previous anticholinergic treatments and found that patients who completed the study on propiverine saw significant improvements in nighttime urinary frequency, urgency, and urgency incontinence. The document concludes that propiverine may be more effective than previous anticholinergic agents for some patients with overactive bladder.
2. What is an Overactive Bladder?
Overactive bladder
(also known as
Overactive Bladder
Syndrome) is a
urological condition
related to problems
with urination. [1]

3. Causes of Overactive Bladder
Causes of overactive bladder: [1]
Age
Diabetes
Certain Medications (diuretics)
Lifestyle Choices
Excessive consumption of Caffeine or
Alcohol

4. Signs and Symptoms of Overactive
Bladder
Sudden urge to urinate that's difficult to control.
Urge incontinence - the involuntary loss of urine immediately
following an urgent need to urinate.
Urinate frequently, usually 8 or more times in 24 hours.
Awaken 2 or more times in the night to urinate (nocturia).
5. Drugs with anticholinergic activity
are the first-line drugs to treat OAB
symptoms.
Drugs used:
• Solifenacin
• Tolterodine
• Imidafenacin
• Propiverine Hydrochloride
First Line of Treatment
6. Effectiveness of Propiverine
Hydrochloride
DUAL ACTION:
1. Anticholinergic activity
+
2. Calcium antagonist activity (not seen in other
anticholinergic agents such as solifenacin, tolterodine
and imidafenacin)

7. What Is An Anticholinergic Agent?
An anticholinergic agent is a
substance that inhibits the
parasympathetic nerve impulses by
selectively blocking the binding of
the neurotransmitter acetylcholine to
its receptor in nerve cells.
Anticholinergics help treat overactive
bladder by affecting the nerve
function of the bladder muscle
(detrusor) to relax.
Helps reduce urinary urgency.
8. Calcium- channel blocker
Calcium – channel
blockers inhibit bladder
contraction by
decreasing calcium
available for smooth-
muscle contraction.
9. Propiverine Hydrochloride vs
Oxybutynin Hydrochloride
A double blind randomized control study
demonstrated that propiverine was superior to
oxybutynin hydrochloride in terms of improvement of
pollakisuria and urinary incontinence associated with
neurogenic bladder and unstable bladder. [1]

11. Summary of the Clinical Study
29 men and 44 women. A total of 73 patients participated in
the clinical study.
Median age of the 73 patients was 71 years.
Out of 73 patients, 52 patients completed the study.
Among subjects who completed the study, OAB symptoms
of nighttime frequency, urgency, and urgency incontinence
(except daytime frequency) showed significant
improvement with propiverine treatment.
