Flavoxate is a smooth muscle relaxant widely used to treat urgency and urge incontinence. It has been used in an unblinded, uncontrolled clinical trial in 14 urology departments in universities and major hospitals in the People's Republic of China involving 361 patients with urgency/incontinence of various types. Patients were given 200 mg three times daily, orally, for 2 weeks, although 33 patients received a daily dosage of 1200 mg. Frequency, urgency, dysuria, nocturia and incontinence were assessed and scored clinically prior to and after treatment. Three departments also included urodynamic investigations, e.g. monitoring of the end-residual volume. Results from 336 evaluable patients indicate that 228 (67%) were completely cured of urgency/incontinence symptoms, 66 (20%) were improved and 42 (13%) patients were unchanged. Flavoxate was also effective in 77.4% of patients refractory to previous anti-cholinergic treatment. Treatment did not increase the end-residual volume and adverse events occurred only in four (1.3%) patients, two (0.6%) of which discontinued the therapy. The 1200 mg dose produced a complete cure in 82% of patients and improvement in the remaining 18%, with no side-effects. In conclusion, flavoxate is an effective and well tolerated treatment for urgency/incontinence of various causes.

A drug utilization observation study collected data on a total of 1800 patients given flavoxate (Spasuret 200) over 2 weeks for urge incontinence. Efficacy and tolerance parameters were determined. A subgroup of 618 patients without urinary tract infections or benign prostatic hyperplasia were treated with flavoxate only. The subgroup (n = 618) showed a reduction of dysuria (37%), nocturia (53%), and both daytime (61%) and nighttime urge (69%). Bladder volume at first urge sensation increased by 55.1+/-58.8 ml (36%), which was comparable to data from the entire group (1800 patients). In 89.2% of all patients the residual urine volume was stable or decreased. Undesirable side effects occurred in 1.8% of cases. Both groups showed better results with flavoxate four times daily (800 mg), compared to three times daily (600 mg). Flavoxate is effective and well tolerated and causes no additional problems due to residual urine or side effects.

The spasmolytic activity of flavoxate (CAS 15301-69-6) and the anticholinergic agents oxybutynin (CAS 5633-20-5), tolterodine (CAS 124937-51-5) and trospium chloride (CAS 10405-02-4), all of which are commonly utilized in the treatment of urinary incontinence, on muscarinic tension and electrically evoked contractions of isolated human detrusor smooth muscle strips was studied using the organ bath technique. Within the concentration ranges tested (trospium chloride 10(-11)-10(-6) mol/l, flavoxate and oxybutynin 10(-9)-10(-5) mol/l, tolterodine 10(-10)-10(-5) mol/l), each drug caused a concentration-dependent relaxation of the tension elicited by muscarinic stimulation and dose-dependently attenuated the contractions induced by electrical field stimulation (EFS). The effects of trospium chloride and tolterodine on carbachol-induced muscarinic tension were more pronounced than those of oxybutynin, while trospium chloride and oxybutynin were most effective in inhibiting the contractions induced by EFS. Flavoxate was significantly less effective than all other drugs tested. Regardless the individual drug concentrations needed for maximal efficacy, the potency of oxybutynin and flavoxate to reverse muscarinic tension and attenuate EFS-evoked contractions was almost comparable while tolterodine and trospium chloride were more effective in relaxing the muscarinic tension of the detrusor strip preparations than causing inhibition of EFS-induced contractions. Our results again underline the ratio for the use of nortropane analogues (trospium chloride) and phenylpropylamine cresols (tolterodine) in the treatment of frequency, urgency and urge incontinence secondary to an overactive bladder.

Overactive bladder (OAB) is a medical syndrome defined by symptoms of urgency, with or without urge urinary incontinence (any involuntary loss of urine), usually with frequency and nocturia. Although anticholinergic agents have been the first-line treatment for OAB for many years, the efficacious pharmacologic management of this condition has been compromised by concerns regarding tolerability. Flavoxate was the first anticholinergic and antispasmodic agent approved by the Food and Drug Administration (FDA) to treat symptoms of OAB but is not routinely used today since newer agents are more effective. The more recent drugs, oxybutynin and tolterodine, have appeared to be equally efficacious in treating the symptoms of OAB in clinical trials; however, tolterodine has proven to be better tolerated with fewer adverse effects. In 2004, the FDA approved the three newest agents for the class: darifenacin, solifenacin, and trospium. Compared with oxybutynin and tolterodine, these agents have a more favorable side effect profile, which can enhance tolerability and patient compliance. Side effects are reduced in part because of the drugs' greater tissue selectivity for inhibiting the bladder muscle contraction over other anticholinergic receptors in the body. In recent clinical trials, darifenacin, solifenacin, and trospium have shown superiority to placebo and efficacy comparable to that of oxybutynin and tolterodine.

Urinary incontinence as a consequence of an insufficient urethral closure mechanism (urethral sphincter mechanism incompetence, USMI) or an impaired storing capacity of the urinary bladder is a considerable side effect of castration in the female dog. Different factors such as breed, body weight and time of spaying have an impact on the risk of urinary incontinence. Loss of urine while the patient is recumbent is the most typical symptom which is first observed at a mean time of 2.8 years after castration. Diagnosis is obtained by excluding other causes, whereas a precise patient history is particularly helpful. Therapy is aimed at increasing the closing pressure of the urethra and/or the compliance of the urinary bladder. Usually success can be achieved by medical therapy, thus surgical intervention is normally not required. In addition to urinary incontinence, coat changes can be observed as an undesirable effect of castration in certain dog breeds. To date, the pathophysiology of decreased urethral closing pressure, altered storing function of the urinary bladder and coat changes induced by castration are still not fully understood. Apart from the well-known hypothesis of estrogen deficiency, altered secretion of the hypothalamic and pituitary hormones GnRH, FSH and LH due to castration may have an influence. In addition to a-adrenergic medication, Flavoxate and Estriol, depot formulations of GnRH analogues have been successfully used to treat urinary incontinence. These depot formulations have also been described for the treatment of coat changes due to spaying.
