Aspirin is a commonly used medication that belongs to the class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). It is primarily used for its analgesic (pain-relieving), antipyretic (fever-reducing), and anti-inflammatory properties. Aspirin is often used to relieve minor aches and pains, reduce fever, and alleviate inflammation. Additionally, it is frequently prescribed for its antiplatelet effects, which help prevent blood clot formation and reduce the risk of heart attack and stroke in individuals at risk for cardiovascular events.
Lisinopril is a medication classified as an angiotensin-converting enzyme (ACE) inhibitor. It is commonly prescribed to treat high blood pressure (hypertension), heart failure, and to improve survival rates following a heart attack. Lisinopril works by inhibiting the activity of angiotensin-converting enzyme, which is responsible for converting angiotensin I into angiotensin II. Angiotensin II is a hormone that constricts blood vessels, leading to increased blood pressure. By inhibiting its production, lisinopril helps to relax blood vessels, reduce blood pressure, and improve cardiac function.
Drug Interactions between aspirin and lisinopril
Interactions between your drugs
aspirin and lisinopril
MONITOR: Some researchers propose that simultaneous administration of aspirin might diminish the vasodilatory and hypotensive effects of ACE inhibitors. Furthermore, some studies suggest that aspirin could compromise or negate the advantages of ACE inhibitors in reducing morbidity and mortality in patients post-acute myocardial infarction, coronary heart disease, and especially congestive heart failure. This potential interference is believed to occur through aspirin's inhibition of cyclooxygenase, which leads to the suppression of prostaglandin synthesis and the prostaglandin-mediated hemodynamic effects of ACE inhibitors. However, evidence regarding this negative interaction is largely inconsistent, and the interpretation of relevant data has often been complicated by various confounding factors as well as the retrospective or post hoc nature of most studies. Available evidence suggests that low-dose aspirin (less than 236 mg/day, and particularly less than 100 mg/day) is unlikely, or at least significantly less likely, to interfere with the effects of ACE inhibitors. Nonetheless, susceptibility to this interaction may vary among individual patients.
MANAGEMENT: Given the current state of evidence, it remains challenging to ascertain the likelihood and clinical significance of a negative interaction between aspirin and ACE inhibitors during long-term therapy, especially in congestive heart failure. Generally, current recommendations do not prohibit the concurrent use of these medications in patients with cardiovascular diseases or risk factors that could benefit from them independently. However, patients on long-term therapy with this combination should undergo regular monitoring of blood pressure and other relevant clinical parameters such as renal function. The lowest effective dosage of aspirin should be utilized.

Differences Between aspirin and lisinopril
Aspirin
Aspirin works by inhibiting the enzyme cyclooxygenase (COX), thereby reducing the production of prostaglandins, which are involved in pain, inflammation, and platelet aggregation.
Lisinopril
Lisinopril inhibits the conversion of angiotensin I to angiotensin II by blocking the action of ACE, leading to vasodilation (widening of blood vessels) and decreased blood pressure.
Alternative to aspirin and lisinopril
Alternatives to Aspirin:
Clopidogrel:
Clopidogrel is an antiplatelet medication similar to aspirin and is often prescribed to reduce the risk of heart attack and stroke in patients who cannot take aspirin.
Alternatives to Lisinopril:
Angiotensin II receptor blockers (ARBs):
ARBs, such as losartan, valsartan, and irbesartan, work by blocking the action of angiotensin II and are often used as alternatives to ACE inhibitors in patients who cannot tolerate ACE inhibitors due to side effects such as cough.
Drug and food interactions

GENERALLY AVOID: Consuming moderate-to-high levels of dietary potassium can lead to hyperkalemia in certain patients using angiotensin-converting enzyme (ACE) inhibitors. Some instances of hyperkalemia have been linked to the consumption of potassium-rich salt substitutes in affected patients. ACE inhibitors can contribute to hyperkalemia by inhibiting the renin-aldosterone-angiotensin (RAA) system.
MANAGEMENT: Patients taking ACE inhibitors should be counseled to avoid diets with moderately high or high levels of potassium. Special attention should be given to monitoring the potassium content of salt substitutes.

GENERALLY AVOID: Simultaneous consumption of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) with ethanol can increase the risk of gastrointestinal (GI) bleeding. This may occur due to a combined local effect on the GI tract as well as the inhibition of prostaglandins, resulting in reduced integrity of the GI lining.
MANAGEMENT: Patients should be informed about this potential interaction and instructed to avoid alcohol consumption while using aspirin or NSAIDs.

MONITOR: Many psychotherapeutic and central nervous system (CNS)-active medications (such as anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, and muscle relaxants) can cause hypotensive effects, particularly when starting therapy or adjusting the dosage. Combining these medications with antihypertensive drugs and other agents that lower blood pressure, especially vasodilators and alpha-blockers, may lead to additional drops in blood pressure and orthostatic hypotension.
MANAGEMENT: It is recommended to exercise caution and closely monitor for the development of hypotension when these medications are used together. Some experts advise against alcohol consumption in patients taking vasodilating antihypertensive medications. Patients should be instructed to avoid sudden changes in position from sitting or lying down and to inform their healthcare provider if they experience symptoms such as dizziness, lightheadedness, fainting, orthostatic hypotension, or rapid heartbeat.

A study has found that when caffeine and aspirin are taken together, there is a 25% increase in the rate of appearance and a 17% increase in the maximum concentration of salicylate in the plasma. Additionally, a significantly higher area under the plasma concentration-time curve of salicylate was observed when both drugs were administered concurrently. The exact mechanism behind this interaction has not been determined. Physicians and patients should be mindful that combining aspirin and caffeine may result in faster increases in salicylate levels.
How to minimize lisinopril interactions
Although lisinopril can interact with many other medications, it can often be used safely with appropriate precautions.
It's crucial to consult a healthcare provider before starting any new medication. Before beginning lisinopril, it's important to inform the provider about all medical conditions, especially if:
- You are pregnant, trying to conceive, or breastfeeding (as lisinopril should not be taken in these situations).
- You have diabetes.
- You have heart disease.
- You have blood vessel issues.
- You have a history of angioedema (swelling).
- You have kidney problems.
- You have low blood pressure.
- You have experienced an allergic reaction to an ACE inhibitor in the past.
Additionally, inform the doctor about all medications, including over-the-counter and prescription drugs, as well as vitamins and supplements. While using lisinopril, avoid starting any new medications unless approved by a healthcare professional.
A healthcare provider may need to adjust a person's medications or change the dose of lisinopril (or another medication) if there's a potential for a drug interaction. Always adhere to medication instructions provided by a healthcare provider.
While taking lisinopril, watch for potential signs of drug interactions, such as symptoms of high potassium levels or indications of liver problems, such as dark urine, pale stools, fatigue, or jaundice. If there are any concerns or questions about drug interactions, it's essential to seek medical advice from a healthcare provider.
Conclusion
The interaction between aspirin and lisinopril is complex and multifaceted. While both medications are commonly used to manage various cardiovascular conditions, their concurrent use can potentially lead to interactions that may affect treatment outcomes. Aspirin, known for its antiplatelet and anti-inflammatory properties, can interfere with the blood pressure-lowering effects of lisinopril, an angiotensin-converting enzyme (ACE) inhibitor. This interaction may result in compromised efficacy of lisinopril in certain individuals, particularly those with cardiovascular diseases.
Additionally, coadministration of aspirin and lisinopril may increase the risk of gastrointestinal bleeding due to their combined effects on prostaglandin synthesis and gastric mucosal integrity. Therefore, it is crucial for healthcare providers to carefully assess the risks and benefits of combining aspirin and lisinopril in individual patients, taking into account factors such as medical history, concomitant medications, and potential drug interactions.
Close monitoring and regular follow-up are essential to ensure optimal therapeutic outcomes while minimizing adverse effects associated with the use of these medications together. Ultimately, patients should be educated about the potential risks and cautioned to seek medical advice if they experience any concerning symptoms while taking aspirin and lisinopril concurrently.
