Flomax vs Uroxatral
Introduction
For patients with benign prostatic hyperplasia (BPH) or other types of prostate enlargement, certain drugs that alter the muscle contractions in the bladder and prostate can help to improve urinary flow and reduce symptoms. Flomax and Uroxatral are two such drugs that are prescribed for BPH. They each impact different receptors related to smooth muscle relaxation, but both have effects in improving lower urinary tract symptoms associated with an enlarged prostate. Flomax is a selective alpha-1A adrenergic antagonist impacting receptors primarily located in the prostate tissue causing it to relax thereby improving urine flow. On the other hand, Uroxatral is classified as a non-selective alpha-1 adrenergic antagonist affecting both alpha-1A & 1D subtypes which not only helps with urine flow but also minimizes urinary urgency often seen at night.

What is Flomax?
Tamsulosin (the generic name for Flomax) was a standout addition to the class of drugs known as alpha blockers, which were developed primarily to treat symptoms associated with an enlarged prostate. Tamsulosin was first approved by the FDA in 1997. Flomax works by relaxing the muscles in both the bladder neck and prostate, effectively facilitating urination. It is commonly prescribed for men experiencing difficulties with urination due to benign prostatic hyperplasia (BPH). Conversely, Alfuzosin (the generic name for Uroxatral), another drug from this class, has similar effects but also boasts a unique characteristic: it only targets receptors present in the urinary tract, not those found elsewhere in the body like other alpha-blockers do. This results in it having fewer side effects such as dizziness and low blood pressure upon standing compared to other drugs that have broader influences on these receptors throughout the body.
What conditions is Flomax approved to treat?
Flomax and Uroxatral are both approved for the treatment of symptoms associated with Benign Prostatic Hyperplasia (BPH):
- Trouble starting a urine stream or making more than a dribble
- Passing urine often, especially at night
- Feeling that the bladder is not completely empty after going to the bathroom
- Pushing or straining to begin passing urine
How does Flomax help with these illnesses?
Flomax (tamsulosin) and Uroxatral (alfuzosin) are both alpha-blockers used to manage the symptoms of an enlarged prostate, or benign prostatic hyperplasia. They work by blocking alpha-1 receptors in the smooth muscle of the bladder neck and prostate. When these receptors are blocked, the muscles relax which improves urine flow and reduces symptoms of an enlarged prostate.
Alpha-1 receptors help regulate multiple bodily functions including heart rate, blood pressure, and urinary function. They're found throughout the body but predominantly in vascular smooth muscle where they control contraction and relaxation. In cases of benign prostatic hyperplasia, these receptors can become overly responsive leading to constricted urinary flow.
By blocking these alpha-1 receptors with Flomax or Uroxatral, patients experience improved urination frequency, decreased night-time urination and reduced difficulty starting a stream.
What is Uroxatral?
Uroxatral, the brand name for alfuzosin, is an alpha-blocker. This means it relaxes the muscles in and around the prostate gland and bladder neck by blocking α1-adrenergic receptors, which can improve urine flow and reduce symptoms of Benign Prostatic Hyperplasia (BPH). Alfuzosin was first approved by the FDA in 2003. Unlike Flomax, another alpha-blocker, Uroxatral does not generally affect blood pressure or cause floppy iris syndrome--a complication that can occur during cataract surgery. Its side-effect profile differs from that of other BPH medications; it is less likely to cause dizziness or a drop in blood pressure when going from sitting to standing (orthostatic hypotension), common effects associated with drugs like Flomax. However, patients on Uroxatral may experience headaches or general fatigue. The ability of Uroxatral to specifically target α1-adrenergic receptors makes it beneficial for treating urinary problems related to BPH without greatly impacting cardiovascular function.
What conditions is Uroxatral approved to treat?
Uroxatral is a medication that has been approved for the treatment of:
- Benign prostatic hyperplasia (BPH), also known as an enlarged prostate. This condition can cause difficulties with urination, such as trouble starting and stopping urine flow.
It's important to note that while both Flomax and Uroxatral are prescribed for similar conditions, they may have different side effects or interactions with other medications. Always consult your healthcare provider before making any changes to your medication regimen.
How does Uroxatral help with these illnesses?
Uroxatral, like Flomax, is a type of drug known as an alpha-blocker. These medications work by relaxing the muscles in the prostate and bladder neck to improve urine flow and reduce symptoms of Benign Prostatic Hyperplasia (BPH). Uroxatral specifically targets receptors located in the lower urinary tract which can lead to muscle relaxation and relief from BPH symptoms. Its unique action on these receptors may help patients with specific issues related to urination such as hesitancy, dribbling, or incomplete emptying that are not sufficiently addressed by other treatments like Flomax. Moreover, Uroxatral does not significantly affect blood pressure levels making it more suitable for certain patients who may be dealing with concomitant cardiovascular conditions. Thus it might sometimes be prescribed when a patient doesn't respond well to other alpha blockers or in combination with them.
How effective are both Flomax and Uroxatral?
Both tamsulosin (Flomax) and alfuzosin (Uroxatral) have established histories of success in treating patients with benign prostatic hyperplasia, a common condition that causes prostate enlargement and consequent urinary problems in men. Both medications are alpha-blockers which work by relaxing the muscles around the bladder and prostate, thereby facilitating smoother urine flow. They were initially approved by the FDA within a decade of each other.
In terms of effectiveness, both Flomax and Uroxatral have demonstrated efficacy for alleviating lower urinary tract symptoms associated with benign prostatic hyperplasia as shown in multiple studies including double-blind clinical trials conducted over the past two decades.
A 2003 study comparing tamsulosin to alfuzosin did not find any significant difference between patients receiving either drug regarding improvement in symptom scores or peak urine flow rates. However, it was noted that alfuzosin (Uroxatral) was less likely than tamsulosin (Flomax) to cause abnormal ejaculation – a side effect some men may wish to avoid.
The safety profiles for both drugs are generally favorable when compared with many other treatments for this condition. Tamsulosin is well-tolerated even among elderly populations who often bear most of the burden from BPH due to age-related increase in its prevalence. The optimal dose showing efficacy is thought to be 0.4mg/day for Flomax; apart from improving urination symptoms, it also improves overall quality of life by reducing waking up at night due to frequent urination urges - an issue commonly faced by those suffering from BPH.
Alfuzosin has been indicated as more effective than placebo at relieving symptoms related to BPH according to a review published in 2016 while demonstrating similar efficacy levels compared with other alpha-blockers such as tamsulosin or doxazosine utilized for first-line treatment options. Significant research on its use involves Alfusozine prescribed alone or alongside another class of drugs called 5-alpha reductase inhibitors depending upon severity and progression rate exhibited by individual patient's disease status; data supporting standalone treatment is robust enough like that available for Tamsulosinin but detailed comparative studies focusing exclusively on these two medicines are still lacking. Nonetheless, owing their unique pharmacokinetic properties where they target specific type-1 receptors located majorly on bladder neck & Prostate area ,both can potentially be beneficial alternatives especially if one does not respond well/develops adverse reactions towards first line Alpha blockers selected initially plus they don't significantly affect blood pressure unlike some older generation Alpha blockers used previously thus minimizing potential cardiovascular risks .

At what dose is Flomax typically prescribed?
Oral dosages of Flomax (tamsulosin) are typically 0.4 mg/day, taken once daily approximately half an hour after the same meal every day. If there is insufficient response to this dose, doctors may increase it to 0.8 mg/day after two to four weeks of therapy. On the other hand, Uroxatral (alfuzosin) is commonly prescribed as a 10mg tablet taken once daily immediately after the same meal each day. Dosage adjustments are not usually necessary but should only be made with a doctor's approval in any case.
At what dose is Uroxatral typically prescribed?
Uroxatral treatment is typically initiated at a dosage of 10 mg/day, taken immediately after the same meal each day. It's not recommended to increase this dose as Uroxatral has been designed for once-a-day administration. In case there is no significant improvement or response to treatment with the initial daily dosage after a few weeks, it would be advisable to consult your doctor rather than increasing the dose yourself. The medication should be consumed whole and not chewed or crushed as it can impact its effectiveness in managing symptoms of benign prostatic hyperplasia (BPH).
What are the most common side effects for Flomax?
Common side effects of Flomax (Tamsulosin) include:
- Dizziness
- Lightheadedness
- Weakness and fatigue
- Nausea and vomiting
- Abnormal ejaculation or decreased sex drive
- Runny or stuffy nose
- Insomnia
Uroxatral (Alfuzosin), on the other hand, may cause:
- Fatigue, drowsiness
- Headache
- Stuffy nose, sore throat
- Chest pain
- Low blood pressure causing lightheadedness upon standing up quickly.
It's important to remember that while these are potential side effects, they might not be experienced by everyone. It is always advisable to consult your healthcare provider before starting any new medication.
Are there any potential serious side effects for Flomax?
Uroxatral and Flomax are both used to treat enlarged prostate, but they can have different side effects. In rare cases, these may include:
- Allergic reactions: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing
- Severe stomach/abdominal pain
- Yellowing eyes or skin
- Dark urine

Flomax specifically might cause a condition known as priapism - a painful or prolonged erection lasting 4 or more hours. If this occurs, stop using this drug and get medical help right away.
For Uroxatral users there's a small risk of experiencing symptoms such as chest pain, irregular heartbeat (especially during sexual activity). Also it might lower your blood pressure - causing dizziness or fainting.
If you experience any of these severe side effects while taking either medication, seek immediate medical attention.
What are the most common side effects for Uroxatral?
While taking Uroxatral, some common side effects you may experience include:
- Dizziness or faintness
- Headache
- Fatigue
- Upper respiratory tract infection symptoms like stuffy nose and sore throat
- Chest pain
- Rapid heartbeat (tachycardia)
- Stomach discomfort including nausea and constipation
- Sleep disturbances such as insomnia However, it's important to note that not everyone experiences these side effects, and they often subside after the body adjusts to the medication. Nonetheless, if any of these persist or worsen, it is advisable to consult your healthcare provider immediately.
Are there any potential serious side effects for Uroxatral?
While Uroxatral is generally considered safe, it can cause some serious side effects in rare instances. Monitor for symptoms that may include:
- Signs of an allergic reaction such as hives, difficulty breathing, swelling in your face or throat
- Chest pain and fast or pounding heartbeats
- Lightheadedness which may lead to fainting
- A severe skin reaction—fever, sore throat, swelling in your face or tongue, burning sensation in the eyes followed by a red or purple skin rash that spreads (in particular on the face and upper body) causing blistering and peeling
- Fever along with flu-like symptoms
- Erection problems including painful erections lasting longer than 4 hours
Should any of these potentially adverse reactions occur while taking Uroxatral, seek immediate medical attention.
Contraindications for Flomax and Uroxatral?
Both Flomax and Uroxatral, like most other medications for benign prostatic hyperplasia (BPH), may worsen symptoms of orthostatic hypotension in some people. If you notice your blood pressure dropping significantly upon standing or a sudden onset of dizziness, please seek immediate medical attention.
Neither Flomax nor Uroxatral can be taken if you are taking, or have been taking certain medications including other alpha blockers or erectile dysfunction drugs. Always tell your physician which medications you are taking; it is crucial to prevent dangerous interactions with Flomax and Uroxatral.
In addition, both these drugs should not be used if you have severe kidney disease or moderate to severe liver disease. They are also contraindicated in individuals who had a prolonged erection (priapism) in the past as these medicines could potentially cause this condition again.
How much do Flomax and Uroxatral cost?
For the brand name versions of these drugs:
- The price for 30 capsules of Flomax (0.4 mg) averages around $170, which works out to approximately $5.66/day.
- The price for 30 tablets of Uroxatral (10 mg) averages around $110, working out to roughly $3.66/day.
Thus, if you are taking the recommended daily dose for either medication, then brand-name Uroxatral is less expensive on a per-day treatment basis than Flomax.
However, cost should not be your primary consideration in determining which drug is right for you; rather it's advised that you consider efficacy and side effects as well as any other health issues or medications that may interact with these drugs.
As for the generic versions—tamsulosin (Flomax) and alfuzosin (Uroxatral), costs are significantly lower:
- Tamsulosin can come in packs ranging from 30 to 90 capsules with approximate costs varying from about $0.40 to about $1.50 per day depending upon where you purchase them.
- Alfuzosin also comes in different pack sizes starting at around 15 up to potentially hundreds of tablets with costs ranging between just over $.25/day up towards about $.75/day once again depending upon quantity purchased and location bought from.
Popularity of Flomax and Uroxatral
Tamsulosin, available in generic form and under the brand name Flomax, is a commonly used drug to treat benign prostatic hyperplasia (BPH), or an enlarged prostate. In 2020, it was estimated that about 9 million people were prescribed tamsulosin in the US. Tamsulosin accounts for roughly 35% of all BPH prescriptions in the United States.
Alfuzosin, also known as Uroxatral, is another medication used for treating symptoms of BPH. Although not as prevalent as tamsulosin, alfuzosin still had approximately 1.2 million prescriptions filled nationwide in 2020 accounting for about 5% of all BPH-related prescriptions. The prescription volume for both medications has been steady over recent years with no significant changes noted.
Conclusion
Both Flomax (tamsulosin) and Uroxatral (alfuzosin) are widely used for managing the symptoms of an enlarged prostate (BPH), with numerous clinical studies supporting their efficacy over placebo treatments. Both belong to a class of drugs known as alpha-blockers, which work by relaxing the muscles in the bladder neck and prostate, allowing easier urination.
Flomax is commonly considered as a first-line treatment option due to its selectivity for alpha-1A adrenergic receptors, which are predominantly found in the prostate. On the other hand, Uroxatral is less selective but has been shown to be equally effective when taken once daily.
Both drugs are available in generic form that offers significant cost savings especially for patients who must pay out-of-pocket. It might take some time before noticeable improvements occur upon starting either medication.
The side effect profiles of both medications are fairly similar and typically well-tolerated; common ones include dizziness, abnormal ejaculation, and reduced semen volume with Flomax being slightly more associated with these effects than Uroxatral. Patients should monitor any symptoms closely after starting treatment and seek immediate medical help if they notice severe side effects such as fainting or persistent dizziness.
