What is Lisinopril?

Lisinopril can be used alone or with other medications in the treatment of high blood pressure in adults and children aged 6 years and older.Adults can also take Lisinopril to treat congestive heart failure and to increase survival following a heart attack.Lisinopril belongs to a class of medications called angiotensin-converting enzyme (ACE) inhibitors. This product works by reducing chemicals which tighten the blood vessels.Blood flows more freely, and the heart pumps blood more efficiently.When left untreated, high blood pressure can damage the brain, the heart, the blood vessels, the kidneys, and other organs. These organs can be damaged and cause heart disease, stroke, kidney damage, a heart attack, or heart failure. Making lifestyle changes can help control blood pressure in addition to medication. This includes eating a low-fat and salty diet, maintaining a healthy body weight, exercising for at least 30 minutes every day, not smoking, and drinking alcohol in moderation.

Details on dosage

Usual Adult Dose for Hypertension:

Initial dose: 5 mg orally, once daily; 10 mg orally
Maintenance dose: 20–40 mg orally, once daily.
The maximum dose is 80 mg taken orally, once per day.
The initial dose for patients who are receiving diuretics is 5mg orally, once per day.
The 80 mg dose was used, but it did not seem to have a greater effect.
If lisinopril is not controlling blood pressure, you can add a small dose of diuretic (e.g., hydrochlorothiazide, 12.5mg). It may be possible, after the addition of diuretics, to reduce the dosage of lisinopril.

Adult dose for congestive heart failure:

Initial dose: 2.5 to 5 mg taken orally, once per day.
Maintain dose: Increase dosage as tolerated.
Maximum dose: 40mg orally, once daily.
The diuretic dosage may need to be adjusted to minimise hypovolemia, which can contribute to hypotension. It is not necessary to stop lisinopril if hypotension occurs after the first dose.

Adult dose for myocardial infarction:

Initial dose: Orally 5 mg (within 24 hours of the onset of acute infarction).
Subsequent dosages: 5mg orally every 24 hours and 10mg orally every 48 hours.
Maintenance dose: oral, 10 mg once per day. The dose should be continued for at least six weeks.
In the first three days following the infarction, patients with low systolic pressure (less or equal to 120 mmHg but greater than 100 mmHg) should begin treatment at 2.5mg. If hypotension persists (systolic pressure below 90 mmHg) for longer than one hour, the therapy should be discontinued.
Uses: Reduce mortality in acute myocardial ischemia
