Reflav

Reflav Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Reflav is a brand name. Its generic name is Flavoxate.

Reflav

Reflav is a synthetic compound used to relax the smooth muscle of the urinary bladder, enabling it to hold more urine and thus aiding relief of urinary frequency and urgency caused by bladder inflammation (cystitis). It also helps to reduce the sense of urgency and the amount of urine leakage.

Uses for Reflav

Reflav is primarily indicated for the treatment of bladder spasms, irritative bladder symptoms such as urinary frequency and discomfort, urgency, and nocturia, as well as for the treatment or prevention of dysuria following cystoscopy or radiation cystitis.

Mechanism of Action

Reflav causes relaxation of smooth muscle and exhibits anticholinergic activity by blocking the muscarinic action of acetylcholine, mainly on the bladder musculature. This reduces frequency of contracting detrusor and reduces smooth muscle spasms in overactive bladder (OAB).

How Long Does it Take to Work?

Reflav takes effect within one hour of ingestion, with the greatest improvement in symptoms at four hours, and symptom relief is usually maintained up to 24 to 48 hours.

Absorption

Reflav is rapidly absorbed from the gastrointestinal tract with an onset of action at 1 hour after oral administration. Peak plasma levels occur within 2 – 3 hours with a bioavailability of 73%. It is well distributed in the body, with an apparent volume of distribution of 0.46 L/kg.

Route of Elimination

Reflav is metabolized by the liver and mostly eliminated in the urine as inactive metabolites. The elimination half-life is 4 – 6 hours.

Dosage

The recommended starting dose of flavoxate is 100 mg three times a day, administered orally. Depending on individual response and symptom control, the dose can be increased to 200 mg three times a day. The maximum recommended daily dose is 600mg.

Administration

Reflav should be taken orally with a glass of water. It can be taken with or without food, but taking with food may help to reduce digestive side effects.

Side Effects

The most commonly reported side effects of flavoxate include dry mouth, nausea, constipation, dizziness, and drowsiness. Discontinue use and seek medical attention if any serious side effects occur, such as difficulty breathing or a rash.

Toxicity

In a study conducted in rats, the oral LD50 of flavoxate was >5000 mg/kg. No clinical cases of toxicity were reported.

Precautions

• Reflav should be used with caution in patients with impaired renal, cardiovascular, or hepatic function, or in those with urinary obstruction.
• It should not be used in combination with other drugs that impair urination.
• It should not be used in patients with hypersensitivity to flavoxate.

Interactions

Reflav may interact with other drugs, including antibiotics, antispasmodics, antihypertensives, diuretics, and other medications used to treat overactive bladder. It is important to check with your doctor before starting any new medications.

Disease Interactions

• Reflav should not be used in patients with glaucoma, ulcerative colitis, myasthenia gravis, bladder outflow obstruction, or intestinal obstruction.
• It may worsen symptoms if taken in patients with prostatic hyperplasia or bladder neck obstruction.

Drug Interactions

• Reflav may increase the absorption and effects of other drugs, such as carbamazepine, warfarin, and digitalis glycosides.
• It may decrease the effects of anticholinergic drugs, such as oxybutynin and tolterodine.
• It may also interact with other drugs used to treat symptoms of overactive bladder, such as darifenacin, solifenacin, and fesoterodine.

Food Interactions

No food-related interactions are known to occur with flavoxate.

Pregnancy Use

Reflav is listed as a Pregnancy Category B medication, which means animal studies have revealed no evidence of harmful effects to the fetus, but there are no controlled studies available in pregnant women. Reflav should only be used if the potential benefit outweighs the potential risks.

Lactation Use

It is unknown if flavoxate is secreted in breast milk. Because of the potential for serious adverse reactions in nursing infants, women should not use flavoxate while nursing.

Acute Overdose

In the event of an acute overdose of flavoxate, symptomatic and supportive measures should be provided. Gastric lavage or emesis may be beneficial if performed within 1 hour of ingestion.
