A Brief On Lisinopril
Lisinopril is a prescription medication typically used to treat high blood pressure, heart failure, and for treatment after a heart attack. Lisinopril is belongs to a class of drugs called Angiotensin Converting Enzyme (ACE) Inhibitors.
Lisinopril (Zestril) is a prescription medication, so you must consult a doctor before purchasing. Some companies have healthcare professionals on their teams who can assess you before your purchase.
How Does Lisinopril Work?
As mentioned above, Lisinopril is a (ACE) inhibitor. It works by affecting the action of the ACE enzyme, which is responsible for converting angiotensin I to angiotensin II.
Angiotensin II is a hormone that narrows the blood vessels, which may increase blood pressure and make the heart harder to pump blood. By blocking the action of the ACE enzyme, Lisinopril helps to improve blood flow and reduces the workload of the heart.
Usages Of Lisinopril
Lisinopril has both on-label and off-label usage. On-label usages are those that are approved by regulatory agencies and are specifically listed on the drugs. Off-label usages are those that are not specifically approved by regulatory agencies but are still prescribed by doctors based on their clinical judgment and research.
Here are some examples of On-label and off-label usages of Lisinopril.
On-label usages:
- Treatment of hypertension (high blood pressure)
- Treatment of heart failure
- Improvement of survival after a heart attack
Off-label usages
- Treatment of diabetic nephropathy (kidney disease in people with diabetes)
- Prevention of migraines
- Treatment of left ventricular dysfunction (a condition in which the heart’s left ventricle doesn’t pump blood effectively)
- Treatment of scleroderma (a connective tissue disorder)
- Lisinopril for prevention of kidney damage in people with lupus
- Management of chronic cough
- Treatment of Alzheimer’s disease (currently under investigation in clinical trials)
It’s important to note that the off-label usage of Lisinopril without your doctor’s advice may cause serious side effects, so it is only recommended when your doctor prescribes it.
