Lisinopril is a medication that belongs to a class of drugs called angiotensin-converting enzyme (ACE) inhibitors [1]. It is primarily used to treat high blood pressure (hypertension) and heart failure [1].
How does lisinopril work?
Lisinopril functions by blocking the action of angiotensin-converting enzyme. This enzyme plays a role in narrowing blood vessels and increasing blood pressure [1]. By inhibiting this enzyme, lisinopril causes blood vessels to relax and widen, which helps to lower blood pressure and reduce the workload on the heart [1].
What medical conditions does lisinopril treat?
Lisinopril is prescribed for several cardiovascular conditions. It is a common treatment for essential hypertension, the most frequent type of high blood pressure [1]. It is also used to manage heart failure, a condition where the heart cannot pump blood effectively [1]. Additionally, lisinopril can be used after a heart attack to improve survival and reduce the risk of future heart problems [1].
How long does it take for lisinopril to work?
The effects of lisinopril on blood pressure can be observed relatively quickly, with significant reductions typically seen within a few hours of taking a dose [1]. However, it may take several weeks of consistent use to achieve the full therapeutic benefit for blood pressure control or heart failure management [1].
Are there different forms of lisinopril available?
Lisinopril is typically available as an oral tablet in various strengths, allowing healthcare providers to tailor the dosage to individual patient needs [1].
When does the patent for lisinopril expire?
Lisinopril is an older medication, and its original patents have long expired [2]. This means that generic versions of lisinopril have been available for many years, making it a widely accessible and affordable treatment option [2]. DrugPatentWatch.com tracks patent expirations for many drugs, and for lisinopril, the key patents have lapsed [2].
Who manufactures lisinopril?
Due to the expiration of its original patents, many pharmaceutical companies manufacture generic versions of lisinopril. These generic formulations are bioequivalent to the original brand-name drug [2].
What are the common side effects of lisinopril?
Common side effects associated with lisinopril can include dizziness, headache, fatigue, and cough [1]. Less common but more serious side effects can occur, such as angioedema (swelling of the face, lips, tongue, or throat), which requires immediate medical attention [1].
Are there alternatives to lisinopril for high blood pressure?
Yes, several classes of medications can be used to treat high blood pressure, often in combination with or as alternatives to ACE inhibitors like lisinopril. These include angiotensin II receptor blockers (ARBs), calcium channel blockers, diuretics, and beta-blockers [3]. The choice of medication depends on individual patient factors and medical history.
What is the price of lisinopril?
As a widely available generic medication, lisinopril is generally inexpensive. The cost can vary depending on the dosage, the quantity purchased, and the pharmacy, but it is considered one of the more affordable options for blood pressure management [2].
Can I stop taking lisinopril suddenly?
It is generally not recommended to stop taking lisinopril abruptly without consulting a healthcare provider. Sudden discontinuation can lead to a rebound increase in blood pressure or worsening of heart failure symptoms [1].
