Adalat Oros 30 mg, prolonged-release tablets

nifedipine

The Adalat Oros tablet is an innovative prolonged-release system that acts as an osmotic pump that releases nifedipine through a hole drilled into the tablet by laser technology. Once the active ingredient is fully dispersed, the Adalat Oros tablet, which is non-deformable, is excreted entirely in the feces.

The active ingredient, nifedipine, belongs to a series of medications known as calcium antagonists. Medications in this group dilate coronary arteries, increasing blood flow and improving oxygen supply to the heart. On the other hand, nifedipine dilates peripheral arterial vessels, reducing elevated blood pressure.

Adalat Oros is indicated for the treatment of high blood pressure, chronic stable angina (effort angina) and Raynaud's syndrome.
