Altace (Ramipril) — Patient Information Guide (UK)

Altace contains ramipril, a medicine from the group known as ACE inhibitors (Angiotensin-Converting Enzyme inhibitors). It is used to treat a range of cardiovascular conditions and, in some people, can help reduce the risk of serious heart and blood vessel events.

This guide is designed to help you understand how Altace works, how it is usually taken, and what to watch for. Always follow the advice given by your healthcare professional.

Basic product information

• Medicine name: Altace
• Active ingredient: Ramipril
• Medicine type: ACE inhibitor
• Used for: High blood pressure, heart failure, and risk reduction after certain cardiovascular events
• How it is taken: Usually once or twice daily by mouth (exact schedule depends on your condition)

Note: Strengths and pack sizes may vary by product availability in the UK.

How Altace works (mechanism of action)

Ramipril works by blocking the ACE enzyme (angiotensin-converting enzyme). This leads to several helpful effects:

• Lower blood vessel tightening: ACE normally helps produce angiotensin II, a substance that causes blood vessels to constrict. By reducing angiotensin II, blood vessels relax.
• Reduced blood pressure: Relaxed blood vessels help lower blood pressure and reduce the heart’s workload.
• Less “strain” on the heart: In conditions such as heart failure, lowering resistance to blood flow can ease symptoms.
• Improved blood flow and kidney protection in selected patients: In some people, ACE inhibitors can help slow worsening of kidney function, especially in diabetes with protein in the urine (often called albuminuria/proteinuria).

In brief: Altace helps your blood vessels stay wider, reducing pressure and improving how effectively your heart pumps.

Pharmacokinetics (what the body does to the medicine)

Pharmacokinetics describes how the medicine is absorbed, processed, and eliminated.

• Absorption: Ramipril is taken by mouth and absorbed from the gut. The active effect involves conversion in the body.
• Activation (prodrug): Ramipril is a prodrug; it is converted in the body to its active form (ramiprilat).
• Peak levels: The active form typically reaches peak concentration a few hours after dosing, though timing can vary.
• Elimination: The active compounds are cleared mainly by the kidneys and metabolised pathways.
• Half-life: The duration of action is long enough for once-daily dosing in many cases; however, exact timing depends on dose and kidney function.

Kidney and liver function matter: People with reduced kidney function may require dose adjustments and closer monitoring.

Typical uses in the UK

Altace is used for several cardiovascular and kidney-related indications. The best choice of dose and schedule depends on your diagnosis and overall health.

Common indications include:

• High blood pressure (hypertension): To lower blood pressure and reduce cardiovascular risk.
• Heart failure: To improve symptoms and reduce hospital admissions in suitable patients.
• After certain heart and vascular events: To help reduce the risk of cardiovascular events in people with high risk, such as after myocardial infarction (heart attack), stroke, or established peripheral arterial disease—depending on clinical criteria.
• Diabetes-related kidney protection (selected patients): In some patients with diabetes and kidney involvement (commonly proteinuria/albuminuria), ACE inhibitors may help slow progression.

Important: Eligibility for a specific indication depends on your medical history, test results, and overall risk profile.

When to take Altace (timing and routine)

Many people take ramipril as a once-daily dose. Sometimes it is split into two doses per day for symptom control, tolerance, or specific indications.

Practical timing tips

• Pick a consistent time: Taking it at roughly the same time each day helps maintain steady effects.
• With or without food: You can generally take Altace with or without food.
• To minimise dizziness: If you feel light-headed, taking it in the evening may help (discuss with your healthcare professional).
• Do not skip to “catch up”: If you miss a dose, take it when you remember unless it is close to the next dose.

Missed dose guidance (general): If you miss a dose, take it as soon as you remember unless it is almost time for the next dose. Do not take a double dose.

Food interactions

Altace can usually be taken with or without food. Food is not typically a major concern for day-to-day effectiveness.

However:

• Dehydration matters more than food: If you’re unwell (e.g., vomiting/diarrhoea) or not drinking enough, your kidney function and blood pressure may be affected.
• Salt (and “low salt” diets): Cutting salt can further lower blood pressure and may increase the chance of dizziness for some people. Do not make major dietary changes without checking with your clinician.

Alcohol and medicine interactions

Alcohol: Alcohol can increase the chance of dizziness or light-headedness, especially when you start treatment or increase the dose. Moderate or avoid alcohol if you notice symptoms.

Alcohol interaction advice

• Be cautious during the first few weeks and after dose changes.
• If you feel faint, sit or lie down and seek medical advice.

Common medicine interactions (important)

Ramipril can interact with other medicines, potentially affecting kidney function, potassium levels, or blood pressure. Tell your healthcare professional and pharmacist about all medicines you use, including over-the-counter products and supplements.

Key interaction categories include:

• Other blood pressure medicines: May increase the risk of low blood pressure.
• Diuretics (“water tablets”): Some can increase the risk of low blood pressure and kidney function changes when starting or increasing ramipril.
• Potassium supplements or salt substitutes containing potassium: Can raise potassium levels (hyperkalaemia).
• Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen (and higher-dose aspirin): May affect kidney function and reduce the blood pressure-lowering effect in some people, especially during dehydration.
• Potassium-sparing diuretics (e.g., spironolactone, eplerenone): May increase potassium and require monitoring.
• Medicines that can raise potassium (some others may contribute): Your pharmacist can check for specific products.
• Lithium: ACE inhibitors can increase lithium levels, which may be harmful.

Emergency note: If you develop severe weakness, palpitations, confusion, or muscle cramps (possible signs of unusual potassium levels), seek urgent medical advice.

Dosing — how ramipril is usually started and adjusted

Dose depends on the condition being treated, your kidney function, blood pressure, and how you respond.

General dosing principles:

• Start low: Many people begin with a low dose to reduce the chance of dizziness and kidney side effects.
• Increase gradually: The dose is often adjusted over days to weeks, based on symptoms and blood tests (especially kidney function and potassium).
• Monitoring is routine: Your clinician may check blood pressure and blood tests after starting and after each dose change.

Typical dosing ranges (general information)

Exact dosing should follow local prescribing guidance and your personalised plan. As a broad reference, ramipril is commonly used at doses such as:

If you have kidney impairment: dosing may be lower and titration slower. If you have renal artery stenosis or significant kidney disease, special caution applies.

Do not change your dose or stop suddenly without medical advice.

Safety profile — what to watch for

Like all medicines, Altace can cause side effects. Many people tolerate it well, but some effects require urgent medical attention.

Common or important side effects

• Dizziness or light-headedness: Often related to lowered blood pressure, especially when starting or increasing the dose.
• Dry, persistent cough: A well-known ACE inhibitor effect. It may take weeks to appear.
• Headache, fatigue: Sometimes reported.
• Low blood pressure symptoms: Faintness, weakness, blurred vision.

Less common but serious risks

• Angioedema: Swelling of the face, lips, tongue, throat, or difficulty breathing. This is an emergency.
• Kidney function changes: ACE inhibitors can alter kidney function, especially if you are dehydrated or have underlying renal artery disease.
• High potassium (hyperkalaemia): May cause muscle weakness, abnormal heart rhythms, or tingling sensations.
• Allergic reactions: Rash, severe skin reactions (seek urgent advice).
• Yellowing of skin/eyes (jaundice) or severe liver-related symptoms: Seek urgent medical care.

When to seek urgent help

• Sudden swelling of face/lips/tongue/throat or trouble breathing
• Fainting, severe dizziness, or chest pain
• Signs of severe allergic reaction
• Severe reduction in urine output or sudden illness with dehydration

Practical use tips for safer, more comfortable treatment

• Stay hydrated: Dehydration increases the risk of kidney issues and low blood pressure. If you’re unwell with vomiting or diarrhoea, ask your clinician about temporary measures.
• Get your blood tests: Monitoring kidney function (creatinine/eGFR) and potassium is important, especially after starting and dose changes.
• Be cautious when standing up: Rise slowly to reduce dizziness.
• Report a persistent cough: A dry cough is common with ACE inhibitors; your clinician may consider alternatives if it affects quality of life.
• Avoid potassium “boosters” unless advised: Do not use potassium supplements or salt substitutes without checking.
• Keep a medication list: Include any over-the-counter drugs, NSAIDs, herbal products, and supplements.

Alternative options (if Altace isn’t suitable)

If Altace is not tolerated or not appropriate, clinicians may consider other treatments depending on the condition being managed.

Common alternatives

• ARBs (Angiotensin II Receptor Blockers): Examples include losartan, valsartan, and candesartan. These may be used when ACE inhibitor cough occurs, though cross-reactivity for angioedema is a consideration.
• Other blood pressure medicines: Such as calcium channel blockers (e.g., amlodipine) or thiazide-like diuretics (e.g., indapamide), depending on your profile.
• For heart failure: Treatment may include additional medicines (e.g., beta-blockers, mineralocorticoid receptor antagonists), tailored to your case.

Your pharmacist or clinician can explain the rationale for switching options in your specific situation.

Market and legal context in the UK
