Altace (Ramipril) – Patient Information (UK)

Altace contains ramipril, a medicine from the ACE inhibitor (angiotensin-converting enzyme inhibitor) group. It is used to treat high blood pressure and several heart and kidney conditions. This guide explains how Altace works, how it is typically taken, important safety information, and what to consider in everyday life.

Always follow the instructions given by your healthcare professional and read the leaflet supplied with your medicine.

Quick product facts

What is Altace (ramipril) and what does it do?

Altace (ramipril) is a prescription-only medicine in the UK and is used to help control blood pressure and reduce strain on the heart and blood vessels. It can also help protect kidneys, particularly in people with diabetes and certain stages of kidney disease.

Mechanism of action (how it works)

Ramipril helps relax blood vessels and reduces pressure on the heart by blocking an enzyme called ACE. This lowers levels of angiotensin II (a substance that narrows blood vessels) and increases levels of bradykinin, which also supports blood vessel dilation.

As a result, Altace can:

• Reduce blood pressure
• Lower the workload on the heart
• Improve circulation in some people with heart failure
• Help slow kidney damage in selected groups

Pharmacokinetics (how the body handles ramipril)

Pharmacokinetics describes what happens to a medicine in the body—how it is absorbed, transformed, distributed, and eliminated.

• Absorption: Ramipril is absorbed after oral dosing. Food does not generally prevent its effect, but timing can affect how quickly levels rise.
• Activation: Ramipril is converted in the body to its active form (ramiprilat), which is responsible for much of the ACE inhibition.
• Distribution: The active drug circulates in the bloodstream and acts on tissues involved in blood vessel control.
• Elimination: The active drug is mainly cleared by the kidneys. Dose adjustments may be needed in kidney impairment.
• Onset and duration: Blood pressure lowering is typically noticeable within hours, with ongoing effects across the day. Your dosing schedule is designed for steady benefit.

Typical uses in the UK

Altace is used for a range of cardiovascular and kidney conditions. Indications may vary based on your individual assessment.

Common indications include:

• Hypertension (high blood pressure): to lower blood pressure and reduce cardiovascular risk.
• Heart failure: to manage symptoms and reduce risk of hospitalisation in selected patients.
• After a heart attack (myocardial infarction): in certain patients, often as part of risk reduction.
• High cardiovascular risk: to reduce the risk of cardiovascular events in some people with established disease or significant risk factors.
• Diabetic kidney disease / kidney protection: particularly when urine protein is present or in other defined scenarios.

Note: Your prescriber will decide which indication applies to you based on your history, blood pressure, kidney function, potassium levels, and other medicines.

Timing: when to take Altace

Altace is usually taken once daily, but some people may require twice daily dosing depending on dose and the treatment plan.

Practical timing guidance

• Choose a consistent time: Taking it at the same time each day can help you remember.
• First dose considerations: Your first dose or any dose increase may make you feel dizzy, especially if you’re dehydrated or also taking diuretics (water tablets).
• Morning vs evening: Many people take it in the morning; others may be advised to take it at a different time. Follow your guidance.
• If you forget a dose: Take it when you remember unless it’s close to the next dose. Do not double the dose.

Food interactions (can you take it with meals?)

Ramipril can generally be taken with or without food. However, food may affect the speed at which some people absorb the medicine. For most patients, what matters most is maintaining a consistent routine.

• With food: usually acceptable.
• Without food: also usually acceptable.
• Consistency: taking it the same way each day may reduce day-to-day variation.

If you have stomach upset, dizziness, or feel unwell after a dose, speak to a healthcare professional for tailored advice.

Alcohol and medicine interactions

Alcohol

Alcohol can further lower blood pressure and may increase the chance of dizziness or faintness, especially when starting Altace or after dose increases. If you drink alcohol, consider:

• Starting with small amounts and see how you feel
• Avoiding binge drinking
• Staying well-hydrated

Important medicine interactions

Many medicines can interact with Altace because of effects on kidney function, potassium balance, or blood pressure.

Tell your healthcare professional or pharmacist about all medicines you take, including over-the-counter products and herbal remedies.

Common interaction themes include:

• Potassium supplements or salt substitutes: can raise potassium levels, increasing risk of hyperkalaemia.
• Other medicines that raise potassium: some heart failure medicines and certain immunosuppressants.
• Diuretics (“water tablets”): may increase the risk of low blood pressure, particularly around starting or dose changes.
• Non-steroidal anti-inflammatory drugs (NSAIDs) (e.g., ibuprofen, naproxen): in some people, long-term or high-dose NSAIDs may reduce kidney protection and contribute to kidney stress.
• Lithium: ACE inhibitors can increase lithium levels.
• Diabetes medicines: may require monitoring because blood sugar can be affected.

Because individual regimens differ, always check your specific combination with a pharmacist.

Dosing: how much is usually taken?

Altace dosing is individualised. Dose may depend on:

• Your diagnosis (blood pressure vs heart failure vs kidney protection)
• Kidney function
• Potassium level
• Your response and side effects
• Whether you’re taking diuretics or other cardiovascular medicines

General approach (dose titration)

For many patients, clinicians start with a lower dose to reduce the risk of dizziness or abnormal blood test results, then increase gradually (“titration”) based on blood pressure and blood tests.

Important: The exact dose and schedule you should use is determined by your healthcare professional.

Typical dose patterns (example ranges)

In practice, ramipril is commonly available in multiple strengths. Typical dosing regimens may include once-daily or split dosing depending on the indication. Your prescriber will confirm the exact strength and number of tablets.

• High blood pressure: often started low and increased to achieve target blood pressure.
• Heart failure / post-heart event management: usually begins at a low dose with close monitoring.
• Kidney protection in selected patients: often uses a structured titration plan.

If you’re unsure about your strength or how to take your tablets, ask your pharmacist.

Safety profile: who should be cautious?

Altace is effective for many people, but like all medicines it can cause side effects. Some are mild, while others require urgent medical attention.

Common side effects

• Dizziness or light-headedness (often around starting or increasing dose)
• Headache
• Dry cough
• Tiredness
• Nausea or abdominal discomfort in some people

Less common but important effects

• Low blood pressure (hypotension), especially after first dose or if dehydrated
• High potassium (hyperkalaemia) shown in blood tests
• Kidney function changes detected by blood tests
• Changes in blood counts (rare)

Seek urgent medical help if you have

• Signs of angioedema: swelling of face, lips, tongue, or throat; difficulty breathing or swallowing
• Severe allergic reaction symptoms
• Fainting, severe dizziness, or signs of dangerously low blood pressure
• Signs of kidney problems: very reduced urine output, severe fatigue, or rapidly worsening symptoms

Who may need extra caution

• Kidney impairment or reduced kidney function
• History of high potassium
• Dehydration (e.g., vomiting/diarrhoea, poor fluid intake)
• Older adults who may be more sensitive to blood pressure changes
• People taking diuretics or medicines affecting potassium
• People with diabetes who may require close monitoring of kidney function and blood sugar

Practical use tips (to get the best results and stay safe)

• Attend blood test appointments: Ramipril can affect kidney function and potassium, so monitoring is commonly required.
• Know your “sick day” plan: If you develop vomiting, diarrhoea, fever, or you’re unable to drink normally, your healthcare team may advise temporarily pausing certain medicines. Ask for specific instructions.
• Be careful with dehydration: Aim to drink fluids normally unless told otherwise.
• Stand up slowly: This can reduce dizziness, especially in the early stages of treatment.
• Check your blood pressure: Home monitoring can help your clinician adjust treatment. Ensure you use a properly validated device and record readings.
• Don’t start NSAIDs without advice: Frequent ibuprofen/naproxen use can affect kidney function in some people taking ACE inhibitors.
• Be mindful of cough: A persistent dry cough is a known ACE inhibitor side effect. If it bothers you, speak to a pharmacist or clinician about alternatives.

Alternative treatment options

Depending on your condition and tolerance, healthcare professionals may consider other medicines. Alternatives may include:

• ARBs (angiotensin II receptor blockers), such as losartan or candesartan
• Calcium channel blockers for blood pressure (e.g., amlodipine)
• Diuretics (e.g., bendroflumethiazide) in selected cases
• Beta-blockers for certain heart conditions (e.g., bisoprolol, carvedilol)

If you experience problematic side effects (such as angioedema or a troublesome cough), your healthcare professional may advise switching to a different class of medicine.
