Ramipril is an angiotensin-converting enzyme (ACE) inhibitor widely used for the treatment of hypertension (high blood pressure) and to reduce the risk of cardiovascular events in patients with certain risk factors. It works by inhibiting the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, which leads to vasodilation, decreased blood volume, and ultimately, a reduction in blood pressure.
Clinical studies have demonstrated that ramipril effectively lowers both systolic and diastolic blood pressure, resulting in significant reductions in cardiovascular morbidity and mortality. In patients with hypertension, ramipril has been shown to decrease blood pressure consistently over 24 hours, offering prolonged control throughout the day.
Beyond its antihypertensive effects, ramipril is particularly beneficial for patients with additional risk factors, such as a history of myocardial infarction, heart failure, or diabetes, as it has been found to decrease the risk of heart attacks, strokes, and other cardiovascular events. The benefits are often attributed to its ability to improve endothelial function and provide renal protection.
While ramipril is generally well tolerated, common side effects may include cough, elevated potassium levels (hyperkalemia), low blood pressure (hypotension), dizziness, and in rare cases, angioedema (swelling of the deeper layers of the skin). It is essential for patients to be monitored regularly for these potential side effects, especially during the initial stages of treatment or after a dosage increase.
Overall, ramipril is an effective and versatile medication for managing hypertension and providing cardiovascular protection, contributing to improved health outcomes for patients with risk factors for cardiovascular disease. Regular follow-up with healthcare providers is essential for monitoring medication efficacy, blood pressure control, and potential side effects.
Ramipril is typically prescribed for the management of hypertension and heart failure. The usual starting dose for adults is 2.5 mg taken orally once daily, which may be adjusted based on individual patient response and tolerability, with the maximum dosage often reaching up to 10 mg per day.
Ramipril can be taken with or without food, providing flexibility regarding meal timing. It is important to take the medication at the same time each day to maintain consistent levels in the bloodstream. Patients should swallow the tablets whole with a glass of water, and they should not crush or chew them.
If you miss a dose of ramipril and remember it within a few hours of the scheduled time, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule; do not take two doses to make up for the missed one.
For optimal effectiveness, it is essential to follow your healthcare provider’s recommendations regarding dosage adjustments and to attend regular follow-up appointments to monitor blood pressure and kidney function. If you have any questions about missed doses or how to take ramipril, consult your healthcare provider for guidance.

Medicines and their possible side effects can affect individual people in different ways. The following are some of the side effects that are known to be associated with this medicine. Just because a side effect is stated here, it does not mean that all people using this medicine will experience that or any side effect.
Here’s a detailed breakdown of the side effects associated with ramipril, categorized into common, less common, rare, and important considerations:
Common Side Effects
1. Cough: A persistent dry cough is one of the most reported side effects of ramipril, often caused by the accumulation of bradykinin.
2. Dizziness: Patients may experience dizziness or lightheadedness, particularly when standing up quickly, due to lowered blood pressure.
3. Fatigue: Some individuals report feeling unusually tired or lethargic.
4. Headache: Mild to moderate headache may occur during the course of treatment.
5. Nausea: Some patients experience gastrointestinal upset, including feelings of nausea.
Less Common Side Effects
1. Hyperkalemia: Elevated potassium levels in the blood can occur, posing risk for cardiac issues.
2. Hypotension: Abnormally low blood pressure may develop, particularly after the initial dose or following a dose increase.
3. Angioedema: Swelling of the deeper layers of the skin, especially of the face, lips, and tongue. This can occur rarely and may lead to difficulty breathing.
4. Rash: Some patients may develop a skin rash or other allergic reactions.
Rare Side Effects
1. Kidney Dysfunction: Impaired renal function may occur, often evidenced by increased serum creatinine levels and decreased urine output.
2. Pancreatitis: In very rare cases, patients might experience inflammation of the pancreas.
3. Liver Dysfunction: Elevated liver enzymes can indicate potential liver complica tions, requiring monitoring.
4. Neutropenia: A decrease in neutrophils or white blood cells can occur, which increases the risk of infections.
Important Considerations
1. Cough Management: If a persistent dry cough occurs, it may be necessary to switch to another medication class, such as an ARB (angiotensin receptor blocker), which does not cause cough as a side effect.
2. Monitoring: Regular monitoring of blood pressure, renal function, and potassium levels is essential, especially during the first few weeks of treatment or after dose adjustments.
3. Gradual Dose Adjustments: When initiating therapy or changing the dose, careful titration is recommended to minimize the risk of hypotension.
4. Discontinuation: If angioedema occurs, ramipril should be discontinued immediately, and
emergency medical attention should be sought.
5. Pregnancy Consideration: Ramipril is contraindicated in pregnancy, especially in the second and third trimesters, as it can lead to fetal harm.

If any side effects concern you, or you are experiencing any of the side effects mentioned in the patient information leaflet whilst taking this medication, please contact our clinical team or speak to your GP.
Cautions
1. Renal Impairment: Caution is advised when prescribing ramipril to patients with pre-existing renal impairment. Kidney function should be monitored regularly, as ramipril can affect renal function and may require dosage adjustments.
2. Electrolyte Imbalances: Ramipril can lead to elevated potassium levels (hyperkalemia), particularly in patients with renal impairment or those taking potassium supplements or potassium-sparing diuretics. Serum potassium levels should be monitored.
3. Historical Angioedema: Patients with a history of angioedema, whether related to ACE inhibitors or not, should use ramipril cautiously due to the risk of recurrent angioedema.
4. Hypotension: Patients with a history of low blood pressure or those who are volume-depleted (e.g., due to diuretics) should be monitored closely, as ramipril can lead to significant hypotension, particularly after the first dose.
5. Surgery and Anesthesia: Patients undergoing surgery or anesthesia should inform their healthcare provider about ramipril use, as it may affect blood pressure management during and after the procedure.
6. Diabetes: Diabetic patients should be monitored closely, particularly those on concurrent diuretic therapy, as ramipril is capable of altering glucose metabolism.
Warnings
1. Pregnancy and Lactation: Ramipril is contraindicated during pregnancy, particularly in the second and third trimesters, as it may cause fetal harm or death. Women of childbearing age should be advised to use effective contraception while on this medication. It is also advised against during breastfeeding.
2. Cough: A persistent dry cough is common with ACE inhibitors like ramipril. If this occurs and significantly impacts the patient's quality of life, a switch to an angiotensin receptor blocker (ARB) may be considered.
3. Drug Interactions: Ramipril may interact with other medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), diuretics, and potassium supplements, which can increase the risk of adverse effects. Patients should disclose all medications they are taking to their healthcare provider.
4. Avoid Sudden Discontinuation: Abrupt discontinuation of ramipril can lead to rebound hypertension. If discontinuation is necessary, it should be done gradually under the supervision of a healthcare provider.
