    • Kidney Failure
      • Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, medication. Some of the renal causes of kidney failure are from sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis. Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones. Treatment options included diet, medications, or dialysis.
    • Congestive Heart Failure
      • Congestive heart failure (CHF) is a condition in which the heart's function as a pump is inadequate to meet the body's needs. A poor blood supply resulting from congestive heart failure may cause the body's organ systems to fail, leading to a weakened heart muscle and fluid accumulation in the lungs and body tissue. There are many diseases that can impair pumping efficiency and symptoms of congestive heart failure including fatigue, diminished exercise capacity, shortness of breath, and swelling. Treatments include lifestyle modifications, medications, heart transplant, and therapy.
    • High Blood Pressure
      • High blood pressure, also known as hypertension, is a repeatedly elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
    • Diabetes (Type 1 and Type 2)
      • Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
    • Heart Attack
      • Heart attack happens when a blood clot completely obstructs a coronary artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical instability of the heart.
    • Heart Attack Treatment
    • Heart Attack Prevention Overview
      • Heart attacks are the major causes of unexpected, sudden death among men and women. A heart attack is also a significant cause of heart failure. Learn the risk factors for heart attack such as high blood pressure, diabetes, and other heart conditions. Lowering your risk factor, lifestyle changes, and in some cases medication are the most effective way of preventing a heart attack.
    • Pregnancy and Drugs (Prescription and OTC)
      • Taking prescription medications or over-the-counter drugs or supplements should be discussed with your doctor. There are some medications that have been found to cause no problems in pregnancy, however, medications such as Accutane for acne, should never be taken during pregnancy.

GENERIC NAME: enalapril

BRAND NAME: Vasotec

DRUG CLASS AND MECHANISM: Enalapril is a drug that is used for treating high blood pressure. It is in a class of drugs called angiotensin converting enzyme (ACE) inhibitors. ACE is an enzyme in the body that causes the formation of angiotensin II. Angiotensin II causes the arteries in the body to narrow, thereby elevating blood pressure. ACE inhibitors, such as enalapril, lower blood pressure by preventing the formation of angiotensin II thereby relaxing the arteries. ACE inhibitors also improve the effectiveness of the heart in patients with heart failure by reducing the blood pressure that the heart must maintain. Enalapril was approved by the FDA in December 1985.

PRESCRIPTION: Yes

GENERIC AVAILABLE: Yes

PREPARATIONS:

  • Tablets: 2.5, 5, 10, and 20 mg.
  • Injection: 1.25 mg/mL
  • STORAGE: Tablets should be stored at room temperature between 15-30 C (59-86 F). The injectable formulation should be stored at 20 to 25 C (68 to 77 F).

PRESCRIBED FOR: Enalapril is used alone or in combination with other drugs to treat high blood pressure or congestive heart failure. After a heart attack, enalapril has been found to be effective in improving function of the damaged heart and in reducing symptoms and hospitalizations related to heart failure. The intravenous formulation is used when oral administration is not possible.

DOSING: The usual oral dose for treating high blood pressure is 2.5-40 mg once daily. It may also be administered twice daily in two divided doses. The dose for treating heart failure is 2.5-20 mg given twice daily. The usual starting intravenous dose is 1.25 mg administered over a 5 minute period every 6 hours. If a patient is receiving diuretic therapy the initial intravenous dose is 0.625 mg every 6 hours.

DRUG INTERACTIONS: Patients receiving diuretics may experience excessive reduction in blood pressure when enalapril is started. Stopping the diuretic or increasing salt intake prior to taking enalapril may prevent excessive blood pressure reduction. Close supervision for at least 2 hours after the start of enalapril and until blood pressure is stable is recommended if the diuretic cannot be stopped.

Enalapril may increase potassium levels (hyperkalemia) in blood. Therefore, there is an increased risk of hyperkalemia when enalapril is given with potassium supplements or drugs that increase potassium levels (for example, spironolactone [Aldactone]).

There have been reports of increased lithium (Eskalith, Lithobid) levels when lithium is used in combination with ACE inhibitors. The reason for this interaction is not known, but the increased levels may lead to toxicity from lithium. There have been reports that aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Children's Advil/Motrin, Medipren, Motrin, Nuprin, PediaCare Fever, etc.), indomethacin (Indocin, Indocin-SR), and naproxen (Anaprox, Naprelan, Naprosyn, Aleve) may reduce the effects of ACE inhibitors.

Nitritoid reactions (symptoms include facial flushing, nausea, vomiting and low blood pressure) may occur when injectable gold (sodium aurothiomalate [Myochrysine]), used in the treatment of rheumatoid arthritis, is combined with ACE inhibitors, including enalapril.

What is a heart attack?

A heart attack (also known as a myocardial infarction) is the death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Blockage of a coronary artery deprives the heart muscle of blood and oxygen, causing injury to the heart muscle. Injury to the heart muscle causes chest pain and pressure. If blood flow is not restored within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur. Muscle continues to die for six to eight hours at which time the heart attack usually is "complete." The dead heart muscle is replaced by scar tissue.

Approximately one million Americans suffer a heart attack each year. Four hundred thousand of them die as a result of their heart attack.
