Imdur (Isosorbide Mononitrate) - Indications and Dosage

INDICATIONS AND USAGE

IMDUR Tablets are indicated for the prevention of angina pectoris due to coronary artery disease. The onset of action of oral isosorbide mononitrate is not sufficiently rapid for this product to be useful in aborting an acute anginal episode.

DOSAGE AND ADMINISTRATION

The recommended starting dose of IMDUR Tablets is 30 mg (given as a single 30 mg tablet or as 1/2 of a 60 mg tablet) or 60 mg (given as a single tablet) once daily. After several days, the dosage may be increased to 120 mg (given as a single 120 mg tablet or as two 60 mg tablets) once daily. Rarely, 240 mg may be required. The daily dose of IMDUR Tablets should be taken in the morning on arising. IMDUR Extended Release Tablets should not be chewed or crushed and should be swallowed together with a half-glassful of fluid. Do not break the 30 mg tablet.
