How Quickly Does Flomax Work For Kidney Stones

Flomax is the brand name for tamsulosin, which was originally used for benign prostatic hyperplasia. Flomax can also be prescribed to aid in the passage of large kidney stones. It promotes relaxation of the smooth muscles of the ureter, which improves urinary flow and reduces mechanical obstruction created by kidney stones.

Flomax works rapidly and significantly reduces the time it takes to pass stones from the urinary tract within 48 hours of taking the medication. For some people, however, symptoms may take 2-4 weeks to improve.

How To Pass Kidney Stones

Stones cause trouble when they obstruct or block the ureter, the tube which drains urine from the kidney to the bladder. Pain can come and go, depending on the degree of obstruction. If the stone is sitting in the ureter without causing blockage, there may be little or no pain. However, if the stone turns even slightly, it may cause partial or complete blockage, which can cause gradual or sudden onset of severe pain.

The last segment of the ureter runs through the wall of the bladder. Stones frequently become stuck in this part of the ureter. If so, they can cause urinary symptoms, including frequency , urgency , and postvoid fullness . These symptoms mimic the symptoms of urinary tract infection. Patients may think they have a bladder infection, but most often these voiding symptoms are due to the stone. When stones are in the lower part of the ureter, they may also cause pain that is referred to the testicle or the tip of the penis in men or into the vaginal and urethral area in women.

When trying to pass a stone, patients should proceed as follows:

Recent Clinical Trial Finds Tamsulosin Not Effective In Kidney Stone Passage

WASHINGTON The latest research into finding medications to aid the passage of ureteral or kidney stones has shown that tamsulosin is not effective for patients across the board. Previously approved to help men experiencing enlarged prostates, tamsulosin is an Alpha-1 blocker that, in small studies, had been found to be a promising aid to passing kidney stones.

A recent multi-center clinical trial funded by the National Institute for Diabetes and Digestive and Kidney Diseases, revealed no significant support for the use of tamsulosin for kidney stones. The results, published in JAMA Internal Medicine, found no significant effect of patient-reported passage or capture of the stone.

There is no known medication for helping patients pass kidney stones, explained Andrew Meltzer, MD, associate professor of emergency medicine at the George Washington University School of Medicine and Health Sciences. Current guidelines by the American Urological Society call for all patients with stones to receive tamsulosin to help facilitate passage. We will likely have to change the guidelines regarding which groups of patients should receive the medication, he said.

During the six-year trial, patients presented to the emergency department describing pain associated with stones. One tablet of tamsulosin was administered per day for 28 days with few patients reporting stone passage.

What Causes Kidney Stones

Kidney Stones – Types, Formation, Treatment, Prevention

Kidney stones are formed from substances in your urine. The substances that combine into stones normally pass through your urinary system. When they dont, its because there isnt enough urine volume, causing the substances to become highly concentrated and to crystalize. This is typically a result of not drinking enough water. The stone-forming substances are:

  • Calcium.

These and other chemicals are some of the waste products that exit your body.

Two Common Drugs Do Not Help More People Pass Kidney Stones

This is a plain English summary of an original research article

This large, high quality trial found that people with a single kidney stone taking tamsulosin or nifedipine drugs for up to four weeks were no more likely to pass the stone spontaneously than those taking a placebo. This suggests that these drugs should not be offered to people with renal colic who are managed with a “watch-and-wait” approach.

About 80% of participants in either arm of this trial were able to pass the stone spontaneously, without a further procedure.

The prevalence of kidney stones in high income countries has increased over the last 20 years. Problems with stones were associated with 25,000 hospital admissions in England in 2012, costing £11.6 million.

What Did This Study Do

The NIHR funded, SUSPEND study was a randomised, placebo-controlled trial recruiting 1,167 adults with renal colic across 24 NHS hospitals. They were randomly assigned to receive up to 4 weeks’ daily treatment with either tamsulosin , nifedipine or placebo. The primary outcome was spontaneous stone passage by four weeks, as defined by needing no interventions to help the stone pass. Participants, clinicians and trial personnel were not aware of treatment allocation. This was a large, well designed randomised controlled trial conducted in a routine care setting which allows for direct translation of its results into standard clinical practice.

Flomax for Kidney Stones

If you see a lot of older male patients, its likely that youve often had a conversation about the ocular effects of Flomax , an oral medication for men who suffer from benign prostatic hypertrophy . Flomax, an alpha-1a blocker, decreases symptoms of BPH such as frequency, urgency, weak urine stream, difficulty in starting urine flow, dysuria and nocturia.

The decrease in BPH symptomatology observed with tamsulosin is directly related to the drugs ability to preferentially antagonize alpha-1a receptors and, therefore, relax smooth muscle in the prostate and bladder neck. Although other non-subtype alpha-1 blockers exist, tamsulosins affinity and selectivity for the alpha-1a receptor subtype results in superior efficacy in treating BPH without the hypotensive side effects common with less selective agents.1 Unfortunately, it also relaxes the iris dilator muscle, leading to miosis.

In recent years, the use of tamsulosin has expanded to off-label indications in both men and women. Here is an overview.

Off-Label UsesThe most common off-label use of tamsulosin is to assist in the passage of kidney stones by increasing urinary fluid volume and pressure as well as relaxing smooth muscle in the ureters.2 Studies have verified that tamsulosin increases the expulsion rate of kidney stones while decreasing the time to expulsion and the need for adjunctive pain management, hospitalization and surgical intervention.3

How Does Tamsulosin Work

Tamsulosin belongs to a class of drugs known as alpha-blockers, also referred to as Alpha-adrenoreceptor antagonists. As with other alpha-blockers used to treat prostate problems, Tamsulosin works by keeping the hormone norepinephrine from tightening the walls in smaller arteries and veins, thus relaxing muscles around the bladder and prostate to increase urine output. Through this same mechanism, tamsulosin is sometimes used to treat kidney stones by easing their passing through the urinary tract.

Before Taking This Medicine

You should not use Flomax if you are allergic to tamsulosin. Do not take this medicine together with similar medicines such as alfuzosin , doxazosin , prazosin , silodosin , or terazosin .

To make sure Flomax is safe for you, tell your doctor if you have:

  • liver or kidney disease

  • a history of prostate cancer

  • low blood pressure or

  • an allergy to sulfa drugs.

Flomax can affect your pupils during cataract surgery. Tell your eye surgeon ahead of time that you are using this medicine. Do not stop using Flomax before surgery unless your surgeon tells you to.

Although this medicine is not for use in women, Flomax is not expected to harm an unborn baby. If you are a woman using this medication, tell your doctor if you are pregnant or breast-feeding.
