Overactive bladder (OAB) is a combination of urinary symptoms that includes a sudden, strong need to urinate. The major symptom of OAB is a sudden, strong urge to urinate that you can't ignore. Leak urine or have “urge incontinence.” This means urine leaks when you feel the sudden urge to go.
Urinate frequently. You may need to go to the bathroom many times during the day.
Wake up at night to pass urine.
The cost for (branded) oral tablet 10 mg is around $411 for a supply of 30 tablets. It indicates that there is strong need of generic version for affordable healthcare.
The data shows that number of people affected with overactive bladder is 37 million.

Trial no. Trial name Observations
1. To take trial batch by DC
and to study
physicochemical
parameters
All parameters were
found satisfactory and
meet the specification.
Dissolution of generic
Drug X tablets, 10 mg

study impact on
dissolution of drug
It was concluded that
reduced API PSD has no
impact on dissolution of
drug product.
3. To take trial batch 5mg
using reduced particle size
of API to study impact on
dissolution of drug
It was concluded that
