From the Research
Olmesartan does not affect PSA test results. Olmesartan is an angiotensin II receptor blocker (ARB) used to treat high blood pressure, and it works by relaxing blood vessels to lower blood pressure. PSA tests measure a protein produced by the prostate gland, and are used to screen for prostate cancer or monitor prostate conditions. Unlike some medications such as finasteride or dutasteride (5-alpha reductase inhibitors) which can lower PSA levels by approximately 50%, olmesartan has no known mechanism to interfere with PSA production or measurement.
The provided evidence does not directly address the effect of olmesartan on PSA test results. However, based on the pharmacological properties of olmesartan, as described in 1, it is unlikely to affect PSA levels. The studies provided, such as 2, 3, 4, and 5, discuss various topics related to prostate cancer screening, digital rectal examination, and antihypertensive medications, but do not provide specific information on the effect of olmesartan on PSA test results.
If you're taking olmesartan and need a PSA test, you can continue your medication as prescribed without concern about it affecting your test results. However, always inform your healthcare provider about all medications you're taking when undergoing any medical tests. It is essential to consider the potential effects of other medications on PSA levels, as some may interfere with test results, but olmesartan is not known to have such an effect.
