Description:

Flavoxate is a spasmolytic flavone derivative that acts by relaxing the smooth muscle in the urinary tract. Flavoxate is a competitive muscarinic receptor antagonist indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and urinary frequency. Muscarinic receptors play an important role in several major cholin-ergically mediated functions, including contractions of urinary bladder smooth muscle and stimulation of salivary secretion.

Pharmacology:

Flavoxate acts as a direct antagonist at muscarinic acetylcholine receptors in cholinergically innervated organs. Its anticholinergic-parasympatholytic action reduces the tonus of smooth muscle in the bladder, effectively reducing the number of required voids, urge incontinence episodes, urge severity and improving retention, facilitating increased volume per void.

Adults and children over 12 years of age: 100 mg to 200 mg 3 times a day. With improvement of symptoms, the dose may be reduced.

Pediatric Use: Safety and effectiveness in children below the age of 12 years have not been established.
