Heart Disease Home > Nadolol Oral

Nadolol (Corgard®) is a medication often prescribed for the treatment of high blood pressure and angina (chest pain due to inadequate blood supply to the heart). It comes in tablet form and is usually taken by mouth once a day. Oral nadolol tablets are available in three strengths, including:
  • Nadolol 20 mg
  • Nadolol 40 mg
  • Nadolol 80 mg.
Nadolol belongs to a group of drugs called beta-adrenergic blocking agents, more often known as beta blockers. As the name implies, these medications block beta receptors located in a number of places within the body (including the heart and blood vessels). By blocking beta receptors, nadolol decreases the heart rate, blood pressure, and the workload of the heart. This means that the heart requires less blood and oxygen to work properly.
As with any medicine, side effects are possible with nadolol. However, when side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated. Some of the most common side effects of nadolol include, but are not limited to:
  • Slow heart rate (bradycardia)
  • Cold, numb, and pale fingers and toes
  • Dizziness
  • Fatigue.
