It is a drug that is used in various urinary syndromes and as an antispasmodic.
Its therapeutic utility and mechanism of action are unclear. It may have local anesthetic activity and direct relaxant effects on smooth muscle, as well as some activity as a muscarinic antagonist.
Flavoxate is a synthetic parasympatholytic with antimuscarinic, muscle relaxant, and urinary antispasmodic properties.
It binds to and inhibits muscarinic receptors, suppressing the urination reflex and increasing the capacity of the urinary bladder by modifying the center of urination in the brainstem.
Furthermore, this agent has been found to inhibit cyclic AMP formation in the striatal membranes of the brain.
All of this through stimulation of pertussis toxin-sensitive G-protein-coupled receptors that in turn suppress isovolumic urinary bladder contraction.
This drug is used for symptomatic relief of urgency, dysuria, suprapubic pain, nocturia, incontinence, and frequency, as can occur in cystitis , urethritis , prostatitis, and urethrocystitis / urethrotrigonitis.
Flavoxate is a synthetic anticholinergic agent used to treat urinary incontinence and overactive bladder syndrome.
Flavoxate has not been implicated in elevation of liver enzymes or clinically apparent acute liver injury.
