Introduction and Quick Information about Coreg:

Coreg (carvedilol) is included in the class of drugs known as beta-blockers. Beta-blocker can affect the blood circulation i.e. blood flow through veins and arteries as well as the functioning of the heart. This medication is helpful to treat congestive heart failure and high blood pressure (hypertension). The carvedilol works by clogging the receptors of adrenergic nervous system, which is a system of nerves where adrenalin (epinephrine) is active. By blocking these receptors, this drug lowers the heart’s contraction and relaxation rate; thereby stabilizing the working of the heart, causing the blood pressure to fall and arteries to relax.

Is Coreg Approved by U.S. FDA?

Yes, the U.S. FDA (Food and Drug Administration) has approved carvedilol to treat high blood pressure and heart failure.

Usage and Benefits of Coreg:

Coreg is effective for the treatment of multiple health conditions. Some of the most common uses and benefits of Coreg include:

  1. Coreg for High Blood Pressure: Coreg has the ability to lower the diastolic and systolic blood pressure. Higher the dosage of Coreg, lower blood pressure readings will be obtained. By reducing the blood pressure, this drug can also decrease the chances of heart conditions, brain stroke, kidney failure etc. which often take place with the long-term high blood pressure.
  2. Coreg for Congestive Heart Failure – For the people who are suffering from severe to mild congestive heart failure, Coreg (carvedilol) can reduce the blood pressure and enhance the heart functioning. This information is retrieved from several clinical studies where Coreg was pooled with some other effective medications for congestive heart failure, including diuretics, ACE inhibitors, and digoxin (Lanoxicaps, Lanoxin, Digitek).
  3. Coreg For Heart Attack- A heart attack or myocardial infarction is one of the life-threatening events in which the supply of oxygen and blood to the heart parts is blocked for such a long period of time that the heart muscle dies. For those people who have developed left ventricular dysfunction or heart failure following a heart attack, Coreg can reduce the risks of death by around 23 percent by its regular use. Coreg can also prove to be helpful in reducing the strain on the heart.
