Telmisartan is an angiotensin receptor blocker (ARB). It relaxes blood vessels by blocking the action of a chemical that usually makes blood vessels tighter. This lowers the blood pressure, allowing the blood to flow more smoothly to different organs and the heart to pump more efficiently.

Q. Does Tretan work by causing excessive urination?

Q. Do I need to follow any precautions if I take ibuprofen and Tretan together?
If you are taking ibuprofen and Tretan together, you should continuously keep a check on your blood pressure and kidney function. Tretan may enhance the side effects of ibuprofen which may further cause water retention, especially in patients taking Tretan for heart failure. Ibuprofen may interfere with working of Tretan and decrease its efficiency at lowering blood pressure.
