Lasix vs Lisinopril
Introduction
For patients with hypertension or heart failure, certain drugs that influence the pressure and fluid balance in the blood vessels can help manage symptoms and prevent complications. Lasix and Lisinopril are two such medications commonly used to treat these conditions. Both work differently but have significant effects on managing high blood pressure and heart-related issues. Lasix is a loop diuretic or 'water pill' that prevents your body from absorbing too much salt, allowing the salt to instead be passed out through your urine. It helps reduce fluid build-up and swelling caused by heart failure or other health problems. On the other hand, Lisinopril falls under angiotensin-converting enzyme (ACE) inhibitors class of drugs, primarily affecting levels of angiotensin II—a substance which narrows blood vessels—and thereby helping relax vessel walls for better blood flow.
What is Lasix?
Furosemide (the generic name for Lasix) is the first-line diuretic used to treat edema associated with heart failure, cirrhosis, and renal disease, including nephrotic syndrome. It was first approved by the FDA in 1982. Lasix increases levels of free water excretion by preventing it from being reabsorbed back into the body via inhibiting sodium-potassium-chloride cotransporter in thick ascending limb of Loop of Henle within kidneys thereby increasing urine production which aids in removing excess fluid from the body. Contrarily, Lisinopril belongs to a class of drugs called angiotensin-converting enzyme (ACE) inhibitors that primarily treats high blood pressure and heart failure. This drug works by reducing certain chemicals that tighten the blood vessels so blood flows more smoothly and allows your heart to pump more efficiently. Both these drugs are vastly different with respect to their mechanism of action as well as their side effect profile.
What conditions is Lasix approved to treat?
Lasix and Lisinopril are each approved for the treatment of different medical conditions:
-
Lasix, also known as furosemide, is primarily used to treat edema associated with heart failure, renal disease, or liver disease. Additionally, it's employed in the management of hypertension when a diuretic is indicated.
-
Lisinopril on the other hand is an ACE inhibitor that treats high blood pressure and heart failure. Moreover, it's beneficial in improving survival after myocardial infarction (heart attack).
How does Lasix help with these illnesses?
Lasix, also known as furosemide, is a potent diuretic that helps to manage high blood pressure and fluid retention by increasing the amount of urine produced by the kidneys. It does this by inhibiting the reabsorption of sodium and chloride in the nephrons of the kidneys, which leads to an increase in urine volume. An increase in urine output results in a decrease in blood volume, thus reducing blood pressure. Sodium and chloride are electrolytes that help regulate water balance throughout the body. When their concentrations are altered within kidney tubules, it affects how much water is retained or excreted from our bodies.
Lisinopril works differently than Lasix; it's an angiotensin-converting enzyme (ACE) inhibitor used for managing high blood pressure and heart failure. It works by blocking ACE activity leading to decreased levels of angiotensin II – a hormone that causes constriction of blood vessels and release of aldosterone promoting salt and water retention. Therefore, lisinopril relaxes blood vessels making it easier for your heart to pump blood around your body thereby lowering your overall systemic arterial pressure.
What is Lisinopril?
Lisinopril is a brand name for an ACE inhibitor, which stands for Angiotensin-Converting Enzyme inhibitor. This type of medication works by blocking the activity of a specific enzyme involved in the constriction of blood vessels and the release of aldosterone, a hormone that regulates salt and water balance in your body. Lisinopril was first approved by the FDA in 1987. As it is not a diuretic like Lasix (Furosemide), it does not work by reducing fluid volume in your body. Its lack of action on fluid volume means its side-effect profile also differs from that of diuretics, particularly as it does not cause an increase in urination or electrolyte imbalances (common side effects associated with Lasix). The way lisinopril acts to reduce blood pressure can be beneficial for treating hypertension and heart failure, especially among patients who do not respond well to "typical" diuretic drugs such as Lasix.
What conditions is Lisinopril approved to treat?
Lisinopril is an ACE inhibitor that has been approved by the FDA for treatment of conditions such as:
- Hypertension, commonly known as high blood pressure
- Heart failure, to improve survival after a heart attack
How does Lisinopril help with these illnesses?
Lisinopril, in contrast to Lasix, works primarily by inhibiting an enzyme called angiotensin-converting enzyme (ACE). This inhibition results in the dilation of blood vessels and a reduction in fluid volume by decreasing production of angiotensin II. This leads to less constriction of the blood vessels and lowered blood pressure, which can help reduce stress on the heart and kidneys. As with norepinephrine's role in brain function, fluctuations in ACE levels have been implicated as factors contributing to high blood pressure and heart failure. Lisinopril therefore helps alleviate symptoms associated with these conditions. Its action does not significantly affect other aspects like renal filtration rates as Lasix does; hence it is sometimes prescribed when a patient doesn't respond well to diuretics or may be combined with them for more effective treatment.
How effective are both Lasix and Lisinopril?
Furosemide (Lasix) and lisinopril have proven histories of success in treating patients with hypertension and heart failure, despite being released onto the market more than a decade apart. Since they act on different physiological pathways, they may be prescribed under different circumstances.
The effectiveness of furosemide as a diuretic was directly studied in numerous clinical trials since its introduction in 1966; the drug exhibited remarkable efficacy at managing fluid overload conditions such as edema associated with heart failure or renal disease. A study published in 2003 compared furosemide to torasemide, another loop diuretic, and noted that both drugs were equally effective at reducing signs and symptoms of volume overload but had slightly different side effect profiles.
Lisinopril is an ACE inhibitor used primarily for the treatment of high blood pressure, congestive heart failure, and after heart attacks. Introduced into medicinal use in 1988, it has become one of the most widely prescribed medications globally due to its efficacy. Comparing lisinopril to other antihypertensives like amlodipine or losartan shows comparable efficacy rates across these medicines.
A review comparing furosemide's long-term effects versus other diuretics highlighted that regular monitoring was required due to potential electrolyte imbalances triggered by prolonged usage. This medication also showed promising results when combined with other cardiac drugs for improving patient outcomes post-acute myocardial infarction.
In contrast, reviews highlight that lisinopril exhibits not only potent antihypertensive effects but also beneficial actions towards slowing kidney disease progression particularly among diabetic patients. Despite this advantage over many antihypertensive classes though it might induce persistent dry cough which leads some patients to switch therapy.
At what dose is Lasix typically prescribed?
Oral dosages of Lasix (Furosemide) typically range from 20-80 mg/day, but research has demonstrated that a starting dose of 20 mg/day can be effective for managing edema in most individuals. Children and adolescents may require an adjusted dosage based on body weight, typically around 1-2 mg/kg once or twice per day. In either population, the dosage can be increased after several weeks if there is no noticeable improvement. However, the maximum daily dosage should never exceed 600 mg.
On the other hand, oral doses of Lisinopril usually start at 10mg once daily for high blood pressure control in adults and might increase up to a maximum of 80mg per day depending on patient response and tolerance. For children who are able to swallow tablets, the usual recommended starting dose is between .07mg/kg up to a max initial dose not exceeding 5mg once daily. It's important to remember these are general guidelines; always consult with your healthcare provider for personalized medical advice.

At what dose is Lisinopril typically prescribed?
Lisinopril therapy is typically initiated at a dosage of 10 mg/day for high blood pressure and 5 mg/day for heart failure. The dose can then be increased to a maximum of 40 mg per day, taken once daily. Dosage adjustments are usually made every 2-4 weeks depending on the response to treatment. In case of renal dysfunction or if you're concurrently receiving diuretics, your doctor might start you off with a lower initial dose (2.5 - 5mg). It's crucial to monitor kidney function while on Lisinopril as it can impact renal performance especially in patients with existing kidney disease.
What are the most common side effects for Lasix?

Please note that while these are some potential side effects you could experience when taking either drug individually; the chances significantly increase when taken together. Always consult with your healthcare provider before starting any new medication regimen.
Are there any potential serious side effects for Lasix?
Lasix (Furosemide) and Lisinopril are both medications used to treat high blood pressure, but they can have different side effects. When taking Lasix, monitor for these potential symptoms:
- Dehydration or electrolyte imbalances: Symptoms may include dry mouth, increased thirst, confusion, dizziness or fainting spells.
- Allergic reactions: Look out for hives; difficulty breathing; swelling of your face, lips, tongue or throat.
- Hearing problems: Sudden hearing loss or ringing in the ears.
- Liver disease signs: Yellowing of the skin or eyes (jaundice), dark urine or pain in the upper stomach area.
- Unusual bleeding/bruising.
For Lisinopril:
- Signs of elevated potassium levels like muscle weakness and irregular heartbeat
- Kidney issues such as change in amount/color of urine
- Signs suggestive of liver problems like yellowing eyes/skin
- Symptoms related to low white blood cell counts including fever and persistent sore throat If you experience any severe or concerning symptoms while taking either medication, seek medical attention immediately.
What are the most common side effects for Lisinopril?
Lisinopril, an ACE inhibitor primarily used to treat high blood pressure and heart failure, may cause a range of side effects. These can include:
- Dry cough
- Dizziness or lightheadedness due to low blood pressure
- Headache
- Persistent nausea or vomiting
- Signs of kidney problems such as change in the amount of urine
- Serious allergic reactions like skin rash, itching or swelling (especially of the face/tongue/throat)
- Extreme tiredness, fainting
- Muscle cramps and weakness potentially signaling high potassium levels.
Remember that while this list is comprehensive, not everyone experiences all these symptoms. It's always crucial to consult with your healthcare provider if you experience any discomfort while on Lisinopril.
Are there any potential serious side effects for Lisinopril?
While Lisinopril is generally well-tolerated, some people may experience severe side effects. These may include:
- Signs of an allergic reaction such as hives; severe stomach pain, difficulty breathing; swelling of your face, lips, tongue, or throat.
- A light-headed feeling like you might pass out.
- Little or no urination.
- Fever, sore throat.
- High potassium level - nausea, weakness, tingly feeling, chest pain, irregular heartbeats and loss of movement.
If you notice any of these symptoms while taking Lisinopril immediately contact your healthcare provider. You should also be aware that this drug can lower your blood pressure too much in the first few days of treatment causing dizziness and a fainting sensation.
Contraindications for Lasix and Lisinopril?
Both Lasix and Lisinopril, like most other diuretics and ACE inhibitors respectively, may cause some side effects. If you notice any severe reactions such as swelling of the face or throat, difficulty breathing, extreme dizziness or fainting, please seek immediate medical help.
Neither Lasix nor Lisinopril should be taken if you are taking medications known to interact with them. Always inform your physician about all the medications and supplements you are currently taking; certain drugs will require a period of time to clear from your system in order to prevent dangerous interactions with either Lasix or Lisinopril.
For instance, if you're on lithium for psychiatric conditions, it's important to know that both these drugs can increase its levels in your body leading potentially toxic effects. Also avoid nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen while on Lisinopril as they diminish its effect and increase kidney damage risk.
Lasix is not recommended for patients who cannot urinate or have liver disease whereas lisinopril should be avoided in case of angioedema history or pregnancy.
How much do Lasix and Lisinopril cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Lasix (40 mg) averages around $20, which works out to about $0.67/day.
- The price of 30 tablets of Prinivil or Zestril, both brand names for lisinopril (20 mg), averages is about $120, working out to approximately $4/day.
Thus, if you are in the typical dosage range for Lisinopril (i.e., 10–40 mg/day), then brand-name Lasix is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which drug is right for you.
For generic versions:
- Furosemide (the generic form of Lasix) costs significantly less with prices starting as low as $4 for 30 tablets (40mg each). This means your daily cost could be as low as $0.13 /day.
- Generic Lisinopril also has lower costs than its branded counterparts with prices starting from around $10 - $15 for a month's supply depending on dose and location; therefore running between approximately $.33 to $.50 per day if you're taking typical dosages ranging from 10mg to 40mg per day.
Popularity of Lasix and Lisinopril
Furosemide, commonly known by the brand name Lasix, is a potent diuretic that was prescribed to approximately 8 million people in the US in 2020. It belongs to a class of drugs called loop diuretics and it's primarily used to treat edema associated with heart failure, liver disease or kidney disease as well as hypertension. Over the past decade, furosemide has remained one of the most widely used medications for fluid retention and high blood pressure.
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor typically utilized for treating high blood pressure and heart failure, including after heart attacks. In contrast with Furosemide, Lisinopril functions by relaxing blood vessels so that blood can flow more easily. Approximately 87 million prescriptions were written in 2020 making lisinopril one of the top three most-prescribed drugs in America over recent years - accounting for roughly just under 4% of all prescriptions issued across different medicinal categories. The prevalence rate has been consistently significant throughout last decade reflecting its importance as first-line therapy for hypertension.
Conclusion
Both Lasix (furosemide) and Lisinopril have been used widely in patients with heart failure, hypertension, and certain kidney diseases. They are backed by extensive clinical studies demonstrating their effectiveness over placebo treatments. In some cases, these drugs may be combined to achieve better control of blood pressure or fluid retention but always under careful medical supervision due to potential drug interactions. Their mechanisms of action differ significantly: Lasix is a loop diuretic that helps eliminate excess fluid from the body through urine production while Lisinopril is an ACE inhibitor that relaxes blood vessels for easier blood flow.
Lasix is often prescribed as a first-line treatment option for managing acute episodes of fluid retention in heart failure whereas Lisinopril would usually be considered as a long-term therapy for controlling hypertension or improving survival after heart attacks.
Both drugs come in generic forms resulting in significant cost savings especially for those paying out-of-pocket. Both Lasix and Lisinopril might require an adjustment period; hence effects may not be noticeable immediately.
The side effect profile between the two drugs varies. Common side effects associated with Lasix include dehydration and electrolyte imbalance while Lisinopril use can lead to dry cough or hyperkalemia (high potassium levels). It's crucial that patients monitor their symptoms closely when starting treatment and seek immediate medical attention if they notice severe dizziness, fainting or swelling of lips/face/tongue.
