  • DESCRIPTION

    Flavoxate hydrochloride tablets contain flavoxate hydrochloride, a synthetic urinary tract spasmolytic.

    Chemically, flavoxate hydrochloride is 2-piperidinoethyl 3-methyl-4-oxo-2-phenyl-4 H-1-benzopyran-8-carboxylate hydrochloride. The empirical formula of flavoxate hydrochloride is C 24H 25NO 4•HCl. The molecular weight is 427.94. The structural formula appears below.

    Chemical Formula - Flavoxate Hydrochloride

    Each tablet for oral administration contains 100 mg flavoxate hydrochloride. In addition, each tablet contains the following inactive ingredients: colloidal silicon dioxide, corn starch, dibasic calcium phosphate dihydrate, magnesium stearate, hypromellose, polydextrose, polyethylene glycol, titanium dioxide and triacetin.

  • CLINICAL PHARMACOLOGY

    Flavoxate hydrochloride counteracts smooth muscle spasm of the urinary tract and exerts its effect directly on the muscle.

    In a single study of 11 normal male subjects, the time to onset of action was 55 minutes. The peak effect was observed at 112 minutes. 57% of the flavoxate hydrochloride was excreted in the urine within 24 hours.

  • INDICATIONS AND USAGE

    Flavoxate hydrochloride tablets are indicated for symptomatic relief of dysuria, urgency, nocturia, suprapubic pain, frequency and incontinence as may occur in cystitis, prostatitis, urethritis, urethrocystitis/urethrotrigonitis. Flavoxate hydrochloride tablets are not indicated for definitive treatment, but are compatible with drugs used for the treatment of urinary tract infections.

  • CONTRAINDICATIONS

    Flavoxate hydrochloride is contraindicated in patients who have any of the following obstructive conditions: pyloric or duodenal obstruction, obstructive intestinal lesions or ileus, achalasia, gastrointestinal hemorrhage and obstructive uropathies of the lower urinary tract.

  • WARNINGS

    Flavoxate hydrochloride should be given cautiously in patients with suspected glaucoma.

  • PRECAUTIONS

    Information for Patients

    Patients should be informed that if drowsiness and blurred vision occur, they should not operate a motor vehicle or machinery or participate in activities where alertness is required.

    Carcinogenesis, Mutagenesis, Impairment of Fertility

    Mutagenicity studies and long-term studies in animals to determine the carcinogenic potential of flavoxate hydrochloride have not been performed.

    Pregnancy

    Teratogenic Effects-Pregnancy Category B

    Reproduction studies have been performed in rats and rabbits at doses up to 34 times the human dose and revealed no evidence of impaired fertility or harm to the fetus due to flavoxate hydrochloride. There are, however, no well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

    Nursing Mothers

    It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when flavoxate hydrochloride is administered to a nursing woman.

    Pediatric Use

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

  • ADVERSE REACTIONS

    The following adverse reactions have been observed, but there are not enough data to support an estimate of their frequency.

    Gastrointestinal: Nausea, vomiting, dry mouth.

    CNS: Vertigo, headache, mental confusion, especially in the elderly, drowsiness, nervousness.

    Hematologic: Leukopenia (one case which was reversible upon discontinuation of the drug).

    Ophthalmic: Increased ocular tension, blurred vision, disturbance in eye accommodation.

  • OVERDOSAGE

    The oral LD 50 for flavoxate hydrochloride in rats is 4273 mg/kg. The oral LD 50 for flavoxate hydrochloride in mice is 1837 mg/kg.

    It is not known whether flavoxate hydrochloride is dialyzable.
