How does tamsulosin relieve the effects of bph

In any open-label extension trial, particularly when patients are drawn from different prior randomized studies, there are several caveats regarding the strength of the evidence. In general, such studies suffer from a responder bias, by which only satisfied patients elect to continue, thus improving the average response of the entire cohort. This is particularly true when fewer and fewer patients are available for follow-up. The issue of reporting of adverse events AE was discussed by Dr.

Often patients suffering from a given AE in the first year of the trial continue nonetheless and are counted again in subsequent years, leading to an inflation of the overall number of patients with AEs. Roehrborn noted that general policy regarding the reporting of AEs is relatively poor.

He suggests reporting incidence density of AEs for predefined time periods, eg, months 1—3, 4—6, 7—12, and 12—24, which would relate the number of patients with a certain AE to the total number of patients under observation during that time period, by calculating the number of patient months of exposure. Logistically, to be able to capture AEs properly, both the onset and the resolution would have to be noted in the CRFs, such that only new-onset AEs would be reported for each time period.

In addition, other factors influence AEs statistics, such as the intensity with which they are elicited by the coordinators and nurses, whether patients are asked globally about AEs versus being given a laundry list, and the intensity of the follow-up visits. When comparing and meta-analyzing different studies, one could therefore argue that comparisons of standardized outcomes, such as symptom scores and flow rates, are more reliable than comparisons of AEs.

Lastly, the issue of dosage was brought up by Dr. Roehrborn, who mentioned that there really had never been a titration-to-response trial done with tamsulosin. According to Dr. It is clear from all randomized studies that there is a distinct increase in efficacy seen with the 0. However, there is also an increase in the incidence of AEs, most notably ejaculatory disturbances, which may lead to unfavorable risks versus benefit ratio as stated by Dr. To accurately capture the incremental benefits and risks, however, a forced titration in all patients, based on the failure to achieve a predefined threshold of improvement, would be needed, as opposed to a design where the up-titration is left to the patients' discretion.

Historical Background In , Lepor reported on the results of two placebo-controlled, randomized U. European Multicenter Trials Schulman and associates recently reported on the sustained efficacy of tamsulosin in patients from two European open-label studies that were extensions of three double-blind controlled studies over 4 years and noted improvements in symptom scores and urine flow rates. Open in a separate window. PSA, prostate-specific antigen. Discussion The long-term efficacy of medical therapy in BPH is measured by the durability of clinical response, patient satisfaction over several years, and the rate of secondary intervention eg, surgery for acute urinary retention.

In rare cases, tamsulosin may cause a serious allergic reaction anaphylaxis. You could be having a serious allergic reaction and may need immediate treatment in hospital.

These are not all the side effects of tamsulosin. For a full list, see the leaflet inside your medicine packet. You can report any suspected side effects to the UK Safety Scheme.

Tamsulosin is not usually recommended in pregnancy. If you're taking tamsulosin for kidney stones and you're pregnant or trying to get pregnant, talk to a doctor about the benefits and possible harm of taking tamsulosin. The doctor will be able to recommend the best treatment for you and your baby. If you take tamsulosin while breastfeeding there's a risk of the tamsulosin getting into your breast milk.

This may mean your baby gets some side effects from the medicine. It's OK to take take paracetamol , codeine and non-steroidal anti-inflammatory medicines NSAIDs such as ibuprofen while you're taking tamsulosin. There's very little information about taking herbal medicines and supplements with tamsulosin.

Tell a doctor or pharmacist if you're taking other medicines, including remedies, vitamins or supplements. Tamsulosin is a type of medicine known as an alpha-blocker or alpha-adrenoreceptor antagonist.

If you have an enlarged prostate gland it helps by relaxing the muscle around the bladder and prostate gland making it easier to pee. In some cases it can also be used to help ease the passing of kidney stones through the urinary tract. For enlarged prostate — if tamsulosin is helping your symptoms, you can continue to take it long term. Your doctor may check every few months that you're still having relief from symptoms.

For kidney stones — your doctor may tell you to stop taking it if your stones have gone or if the medicine is not helping you. They will tell you to stop taking it if it is no longer needed.

Tamsulosin is generally safe to take for a long time. In fact, it works best when you take it for a long time. Stopping tamsulosin suddenly can make your condition worse as your symptoms may return. If you're bothered by side effects, the doctor may be able to prescribe a different medicine. If you stop taking tamsulosin, it will take 2 to 3 days for it to be completely out of your body. There are a few other medicines that can help with symptoms associated with enlarged prostate.

There are other alpha blockers such as alfuzosin, doxazosin and terazosin. Other medicines for enlarged prostate are 5-alpha-reductase inhibitors, also known as dihydrotestosterone inhibitors — for example finasteride and dutasteride.

Some people may need to take a combination of an alpha blocker and a 5-alpha-reductase inhibitor if a single medicine is not helping their symptoms. If you're going to have cataract or glaucoma surgery, tell the doctor that you're taking tamsulosin in advance. The doctor may advise you to stop taking tamsulosin 2 weeks before surgery. This is because tamsulosin may cause complications during the cataract or glaucoma operation.

For any other surgery, ask the nurse or doctor at your pre-assessment appointment if you need to stop taking tamsulosin. It's usually OK to drink alcohol with tamsulosin.

However, during the first few days of taking tamsulosin, it's best not to drink alcohol. Alcohol can increase the blood pressure-lowering effect and this can make you feel dizzy or lightheaded. It's important to take tamsulosin after breakfast. If you do not eat breakfast, take your medicine after your first meal or snack of the day. Tamsulosin will not stop your contraception working, including the combined pill and emergency contraception.

Some men report problems when they ejaculate when taking tamsulosin such as little or no semen. If you or your partner are taking tamsulosin and you're trying for a baby, speak to a doctor. Tell a doctor or pharmacist if you are taking medicines for erectile dysfunction impotence such as sildenafil , tadalafil or vardenafil, you may find that tamsulosin makes you feel dizzy or lightheaded.

The doctor may tell you to leave a 6-hour gap between tamsulosin and medicines for erectile dysfunction. If you're having problems with your sex life after taking tamsulosin, talk to a doctor. Tamsulosin can make some people feel dizzy or lightheaded, especially when they first start taking it. If this happens to you, do not drive a car, ride a bike, or use tools or machinery.

Because Cialis widens your arteries to let more blood flow to the penis, it can cause your blood pressure to drop. Consuming alcohol can also increase this risk. In rare cases, men have suddenly lost vision or hearing after taking Cialis and other drugs in its class. If you experience hearing or vision loss, you should tell your doctor right away.

Tamsulosin Flomax was one of the first drugs available to treat the urinary symptoms of BPH. Flomax is part of a drug class called alpha-blockers. These drugs work by relaxing smooth muscles in the prostate and bladder neck to let urine flow more freely.

Flomax, or another alpha-blocker, is usually the first drug prescribed for men with mild to moderate urinary symptoms from BPH. You may be at an increased risk for an allergic reaction to Flomax.

This drug can also affect your eyes, and it may interfere with cataract or glaucoma surgery. Talk to your doctor before taking Flomax if you also take an ED drug or blood pressure medication. When combined with Flomax, these can lower your blood pressure too much and increase symptoms like lightheadedness or fainting. Like Cialis, Flomax is available in generic form, which can cost less than the brand name version.

Cialis and Flomax are just two of many drugs that are approved to treat BPH. Find out how these drugs can help your symptoms and what side effects they might cause. Choose the drug that offers the best relief with the fewest risks. Which drug you choose may also depend on what other health conditions you have. Flomax is primarily for BPH.

Benign prostatic hyperplasia BPH may lead to renal, or kidney, failure. Early treatment can help prevent damage to your kidneys.
