Flavoxate is a smooth muscle relaxant with selective antispasmodic effect on the smooth muscle of the genitourinary tract, which can directly relieve the symptoms of urinary frequency, urinary urgency and urinary incontinence caused by the spasm of the smooth muscle of the genitourinary tract. Therefore, flavone permethrin can be used for lower urinary tract infections, such as prostatitis, cystitis and other symptoms of urinary frequency, urinary urgency and pain, and also has a certain therapeutic effect on urinary difficulty and urinary incontinence. It is also used for lower urinary tract obstruction, such as difficulty in urination caused by early and mid-stage prostatic hyperplasia, and functional urethral stricture. For urethral discomfort symptoms after urological instrumentation, such as cystoscopy and ureteroscopy, oral Flavoxate Hydrochloride tablets can also be taken.
