Pharmacodynamic interactions. Concomitant use not recommended. QT prolonging medicinal products Cardiovascular QT prolonging medicinal products e. Non cardiovascular QT prolonging medicinal products e. The concomitant use of cardiovascular and non cardiovascular QT prolonging medicinal products with ivabradine should be avoided since QT prolongation may be exacerbated by heart rate reduction. If the combination appears necessary, close cardiac monitoring is needed see section 4. Concomitant use with precaution. Potassium depleting diuretics thiazide diuretics and loop diuretics hypokalemia can increase the risk of arrhythmia. As ivabradine may cause bradycardia, the resulting combination of hypokalemia and bradycardia is a predisposing factor to the onset of severe arrhythmias, especially in patients with long QT syndrome, whether congenital or substance induced. Pharmacokinetic interactions. Cytochrome P4. 50 3. A4 CYP3. A4 Ivabradine is metabolised by CYP3. A4 only and it is a very weak inhibitor of this cytochrome. Ivabradine was shown not to influence the metabolism and plasma concentrations of other CYP3. A4 substrates mild, moderate and strong inhibitors. CYP3. A4 inhibitors and inducers are liable to interact with ivabradine and influence its metabolism and pharmacokinetics to a clinically significant extent. Drug drug interaction studies have established that CYP3. A4 inhibitors increase ivabradine plasma concentrations, while inducers decrease them. Increased plasma concentrations of ivabradine may be associated with the risk of excessive bradycardia see section 4. Contra indication of concomitant use. The concomitant use of potent CYP3. A4 inhibitors such as azole antifungals ketoconazole, itraconazole, macrolide antibiotics clarithromycin, erythromycin per os, josamycin, telithromycin, HIV protease inhibitors nelfinavir, ritonavir and nefazodone is contra indicated see section 4. The potent CYP3. A4 inhibitors ketoconazole 2. Moderate CYP3. A4 inhibitors specific interaction studies in healthy volunteers and patients have shown that the combination of ivabradine with the heart rate reducing agents diltiazem or verapamil resulted in an increase in ivabradine exposure 2 to 3 fold increase in AUC and an additional heart rate reduction of 5 bpm.

A4 inducers e. g. Hypericum perforatum St Johns Wort may decrease ivabradine exposure and activity. The concomitant use of CYP3. A4 inducing medicinal products may require an adjustment of the dose of ivabradine. The combination of ivabradine 1. St Johns Wort was shown to reduce ivabradine AUC by half. The intake of St Johns Wort should be restricted during the treatment with ivabradine. Other concomitant use. Specific drug drug interaction studies have shown no clinically significant effect of the following medicinal products on pharmacokinetics and pharmacodynamics of ivabradine proton pump inhibitors omeprazole, lansoprazole, sildenafil, HMG Co. A reductase inhibitors simvastatin, dihydropyridine calcium channel blockers amlodipine, lacidipine, digoxin and warfarin. In addition there was no clinically significant effect of ivabradine on the pharmacokinetics of simvastatin, amlodipine, lacidipine, on the pharmacokinetics and pharmacodynamics of digoxin, warfarin and on the pharmacodynamics of aspirin. In pivotal phase III clinical trials the following medicinal products were routinely combined with ivabradine with no evidence of safety concerns angiotensin converting enzyme inhibitors, angiotensin II antagonists, beta blockers, diuretics, anti aldosterone agents, short and long acting nitrates, HMG Co. A reductase inhibitors, fibrates, proton pump inhibitors, oral antidiabetics, aspirin and other anti platelet medicinal products. Paediatric population. Interaction studies have only been performed in adults. Prostate specific antigen PSA test Canadian Cancer Society. A prostate specific antigen PSA test measures the amount of PSA in the blood. PSA is a protein made by prostate cells. It is mostly found in semen, but small amounts of PSA can also be found in the blood of healthy men. Why a PSA test is done. A PSA test may be done to help find prostate cancer early in men who dont have any signs or symptoms of the disease check for cancer in men who have signs or symptoms of prostate cancer confirm a diagnosis when other tests suggest prostate cancer predict a prognosis outcome for prostate cancer predict if cancer has spread outside the prostate plan treatment for prostate cancer monitor men with prostate cancer who are being treated with active surveillance find out if cancer treatments are working find out if cancer has come back recurred after treatment. A PSA test is often used together with a digital rectal exam DRE to increase the chance of finding prostate cancer early when it is easier to treat. Using these tests together is better than using either test alone. Who should have a PSA test. Men older than 5. PSA test. The Canadian Cancer Society recommends that you should also talk to your doctor about PSA testing if you will soon be 5. African ancestry have symptoms of prostate cancer. Benefits and risks. The PSA test can help detect prostate cancer early, but it can also cause false alarms or can miss prostate cancer when its really there. Its important that men talk to their doctor about their personal risk of developing prostate cancer as well as the benefits and risks of PSA testing. Benefits. A PSA test can find prostate cancer early, before it grows large or spreads outside of the prostate. Finding cancer early can mean that treatments will be more successful. Risks. PSA testing carries the following risks. A false positive result on a PSA test suggests that a man might have prostate cancer when he actually doesnt. This happens quite often with PSA testing and only about 1 in 4 abnormal results is due to cancer. A false positive result can lead to unnecessary follow up testing that is more invasive, such as repeated biopsies. It can also cause men and their families unnecessary anxiety and distress. A false negative result means that the test shows that the PSA level is normal even though prostate cancer is present. PSA testing misses about 1. Getting a false negative result may mean that a man and his doctor ignore symptoms of prostate cancer. Overdiagnosis means diagnosing prostate cancer that would never pose a serious threat to a mans health. Overdiagnosis can lead to giving treatments that arent absolutely necessary overtreatment. Research shows that 2. PSA testing may never need to be treated. But most men diagnosed with prostate cancer still choose to have treatment. Unnecessary follow up testing and treatment put a man at risk for problems, including erectile dysfunction and loss of bladder control called urinary incontinence. How a PSA test is done. A PSA test is a blood test that is done in a lab or hospital. Ejaculation can affect PSA levels in the body, so you may be told not to ejaculate for a few days before the test. Tell your doctor if you are taking drugs to treat benign prostatic hyperplasia, prostatitis, urinary problems or baldness. These drugs can lower PSA levels. Find out more about blood tests. What the results mean. PSA levels depend on a mans age. As men get older, their PSA levels naturally go up, but PSA can go up and down for many reasons. Doctors have a hard time agreeing on what is a normal PSA level. But some researchers use a cut off PSA level of around 3 ngm. L to help them decide which men have the greatest risk of developing prostate cancer. Its important for you to discuss your PSA level result and what it means for your risk of prostate cancer with your doctor. Your doctor will help you determine your risk of prostate cancer in relation to your age, family history and other personal information. A higher than normal PSA level doesnt always mean that a man has prostate cancer. High PSA levels can also be caused by an enlarged prostate due to benign prostatic hyperplasia an inflamed or infected prostate called prostatitis a urinary tract infection a recent medical test or procedure on the prostate, such as a transrectal ultrasound TRUS or biopsy a urinary catheter a bladder exam sexual activity that includes ejaculation bike riding often or a recent long bike ride warmer climates. Sometimes the PSA level goes up temporarily after a couple of years of receiving radiation therapy to treat prostate cancer. This is called a PSA bounce. In most cases, the PSA level will fall the next time it is checked. Treatment isnt needed unless the PSA level continues to rise. There is no limit to how high a PSA level may rise. But some men with prostate cancer will have a normal PSA level. For these reasons, researchers are still trying to find out the best way to use the PSA test to find prostate cancer. They are also looking for other ways to find prostate cancer early. What happens if your PSA is high. If you have a high PSA level, your doctor will talk to you about your options. Together you will decide if you need other tests, procedures, follow up care or treatment. The type of follow up care you receive will depend on whether or not you have already been diagnosed with prostate cancer. Usually the first thing doctors will do to follow up on a high PSA level is another PSA test and a DRE. The result of the follow up PSA test is compared to the first test. If the PSA level is still high, your doctor may use one of these follow up procedures serial PSA testing, including PSA velocity and PSA doubling time testing for free PSA in the blood PSA density of the prostate and PSA density of the transition zone the part of the prostate that surrounds the urethra nomograms. If your PSA level continues to rise or the doctor feels a lump on the prostate during a DRE, follow up tests may also include urine tests, such as a urinalysis a transrectal ultrasound TRUS x rays a bladder exam called a cystoscopy a prostate biopsy The following are newer PSA tests and different ways of using the PSA test. They can be used to follow up on a high PSA level. Researchers are also trying to find out if they can find prostate cancer better than with regular PSA testing. Serial PSA testing. Serial PSA testing is mostly used to monitor a mans response to cancer treatment. It is less useful at diagnosing prostate cancer. Serial Key Instagram Er For Mac. Serial PSA tests look at changes in the PSA level over time. This is important because PSA levels tend to go up and down even in men who dont have prostate cancer. But men with prostate cancer will have PSA levels that rise more quickly over time than men who dont have prostate cancer. Serial PSA testing measures the PSA velocity and PSA doubling time. PSA velocity measures the change in the level of PSA over time. To find out the PSA velocity, doctors compare the results of 34 PSA tests that are done over 1. Some research shows that PSA velocity that rises quickly can help doctors diagnose prostate cancer. PSA doubling time measures the time it takes the PSA level to double. The result is calculated in time. For example, a PSA doubling time of 3 years means that, on average, the PSA level doubles every 3 years. PSA doubling time can help doctors find out if a prostate cancer is aggressive, which means it is more likely to grow quickly and spread.
