Stronazon MR (tamsulosin)

How does it work?

Stronazon MR capsules contain the active ingredient tamsulosin hydrochloride, which is a type of medicine called an alpha blocker. It works by blocking alpha receptors that are found in the muscle in the prostate gland.

The prostate gland, which is found only in men, lies at the top of the tube connecting the bladder to the outside (urethra). The prostate gland often enlarges with advancing age (benign prostatic hyperplasia), pressing on the urethra and obstructing the flow of urine from the bladder. This can cause various urinary symptoms, such as difficulty passing urine.

Tamsulosin blocks alpha receptors in the muscle of the prostate gland, which causes the muscle in the prostate to relax. This allows urine to flow freely past the prostate and relieves the urinary symptoms.

Stronazon MR are modified release capsules. They are designed to release the tamsulosin gradually as they pass through the stomach and intestine, so that a steady amount of medicine is absorbed into the bloodstream throughout the day. The capsules are taken once a day, preferably after breakfast. The capsules must be swallowed whole and not chewed, broken or crushed, as this would stop the modifed release action from working.

What is it used for?

- Enlarged prostate gland .

Warning!

- This medicine may cause dizziness, light-headedness and on rare occasions fainting. Take care when moving from a lying down or sitting position to sitting or standing, particularly if you wake up in the night, until you know how this medicine affects you. If you feel dizzy or light-headed at any time during treatment, sit or lie down until the symptoms pass.
- This medicine may cause drowsiness, dizziness or blurred vision and so may affect your ability to drive or operate machinery safely. Do not drive or operate machinery until you know how this medicine affects you and you are sure it won't affect your performance.
- This medicine does not cause prostate cancer, but prostate cancer can be another cause of an enlarged prostate gland. For this reason, tests for prostate cancer should be carried out before you start treatment with this medicine, and at regular intervals thereafter. One test that can be carried out is a digital rectal examination (DRE). The other is to measure the level of prostate specific antigen (PSA) in the blood.
- If you are scheduled to have eye surgery for cataracts it is important to let your eye specialist know if you are or have been taking this medicine. This is because tamsulosin can make your pupil dilate poorly and the iris (the coloured circular part of the eye) become floppy during the procedure. The specialist needs to know if you have been taking this medicine so they can take appropriate precautions with the medicines and techniques they use during the surgery.

You may be asked to stop taking this medicine for a period of time before cataract surgery. Check with your doctor.
