nadolol (Corgard) (cont.)

Pharmacy Author:
Medical and Pharmacy Editor:

Heart pain (angina) occurs when the workload of the heart requires more oxygen than the blood can supply. By slowing the heart rate and decreasing the force of contractions of the heart, nadolol reduces the demand of the heart's muscle for oxygen and thereby prevents angina. Beta blockers may cause difficulty breathing since they cause the muscles surrounding the air passages of the lung to contract, thus narrowing the air passages and making it more difficult for air to pass through . The FDA approved nadolol in 1979.



PREPARATIONS: Tablets: 20, 40, 80 mg.

STORAGE: Nadolol should be stored at room temperature, 15 C -30 C (59 F - 86 F).

PRESCRIBED FOR: Nadolol is used for the treatment of high blood pressure (hypertension) and chest pain (angina). Nadolol also has been used to treat abnormal heart rhythms, tremor, and to prevent migraine headaches and anxiety.

DOSING: The recommended dose is 40-320 mg once daily. The maximum dose for treating angina is 240 mg daily and for hypertension is 320 mg daily. Nadolol may be administered with or without food. The dose for preventing migraines is 40 to 240 mg daily.

DRUG INTERACTIONS: The blood pressure-lowering effects of nadolol are additive with other medications that lower blood pressure, and combinations of these other medications with nadolol often is used for treating persons with high blood pressure. When used in combination with diltiazem (Cardizem; Tiazac; Dilacor), verapamil (Calan, Isoptin, Verelan, Covera), amiodarone (Cordarone), or digoxin (Lanoxin), however, nadolol can cause complete block of the heart's electrical system, a life-threatening condition.
