Lisinopril is a medication used to treat high blood pressure and heart failure [1]. It is available in a 5 mg tablet form, among other dosages [1]. Lisinopril works by relaxing blood vessels, which lowers blood pressure and reduces the workload on the heart [1].
How Does Lisinopril Work to Lower Blood Pressure?
Lisinopril belongs to a class of drugs called ACE (angiotensin-converting enzyme) inhibitors [1]. It functions by blocking the action of angiotensin II, a substance in the body that narrows blood vessels and raises blood pressure [1]. By inhibiting ACE, lisinopril prevents the formation of angiotensin II, leading to vasodilation (widening of blood vessels) and a decrease in blood pressure [1].
What Other Conditions Does Lisinopril Treat?
In addition to hypertension, lisinopril is also prescribed to improve survival after a heart attack and to manage heart failure [1]. Its ability to reduce strain on the heart makes it beneficial in these cardiovascular conditions [1].
How Long Does Lisinopril Take to Start Working?
The effects of lisinopril on blood pressure can typically be observed within a few hours of taking a dose, with peak effects occurring within 6 to 8 hours [1]. However, it may take several weeks of regular use to achieve the full therapeutic benefit for blood pressure control [1].
Are There Different Strengths of Lisinopril Available?
Yes, lisinopril is available in various tablet strengths, including 2.5 mg, 5 mg, 10 mg, 20 mg, 30 mg, and 40 mg [1]. The specific dosage prescribed depends on the individual patient's condition and response to treatment [1].
What Are Potential Side Effects of Lisinopril?
Common side effects of lisinopril can include dizziness, headache, fatigue, and a dry cough [1]. Less common but more serious side effects may involve angioedema (swelling), kidney problems, and changes in blood cell counts [1]. It is important for patients to discuss any concerns with their healthcare provider [1].
