Patients having urinary retention requiring catheterization. 4. Patients having symptomatic, untreated urinary tract infection not resolved prior to starting of investigational products. 5. Patients taking Botulinum toxin injection for urgency urinary incontinence (UUI) in the last year. 6. Patients current therapy with peripheral or sacral neuromodulation. 7.

Patients with severe renal insufficiency or ongoing/planned dialysis. 12. Patients with clinically significant impaired hepatic function (SGOT & SGPT more than 3X the UNL and/or Total bilirubin more than 2X the UNL) at screening. 13. Patients who are unwilling to use contraception while receiving investigational product. 14. Patients with failure to control systemic fungal, bacterial or viral infection. 15. Patients with known case of infection with hepatitis B, hepatitis C or HIV. 16. Patients with a history of neurological or psychiatric disorders, including epilepsy or dementia. 17.
