Imdur

Imdur is a member of the nitrate medication class. Blood arteries dilate (widen) when Imdur is taken, facilitating easier blood flow and heart pumping. Additionally, this treatment is recommended to stop angina attacks (chest discomfort). However, Imdur won’t treat angina that has already started.

Norvasc

Norvasc belongs to a group of medicines called calcium channel blockers. By blocking calcium, Norvasc relaxes and widens blood vessels so blood can flow more easily. Lowering high blood pressure helps prevent heart attacks, strokes, and kidney problems.
