Ramipril Oral Solution 2.5mg/5ml SF

For patients who find it difficult to swallow capsules or tablets, a liquid formulation can make it much easier to take essential medicines consistently. Ramipril oral solution is a prescription-only liquid ACE inhibitor containing the same active ingredient as Ramipril capsules, used for hypertension treatment, heart failure, and cardiovascular protection. As a liquid antihypertensive, it provides the same blood pressure control and cardiovascular therapy benefits as the capsule form, with the practical advantage of flexible dosing for patients who need it. A prescription can only be issued following a clinical consultation.

Ramipril oral solution is a liquid prescription medicine containing Ramipril as the active ingredient. It belongs to the ACE inhibitor class of medicines, which act on the renin-angiotensin system to lower blood pressure and reduce cardiovascular risk. Ramipril oral solution delivers the same active ingredient as Ramipril capsules or tablets, but in a liquid form that can be measured and swallowed without the need to take a solid capsule.

Ramipril oral solution is licensed in the UK for the same indications as Ramipril capsules: treatment of hypertension, symptomatic heart failure, prevention of cardiovascular events in patients at high cardiovascular risk, and nephroprotection in patients with type 2 diabetes and microalbuminuria. The liquid formulation is available in one strength: 2.5 mg/5 ml. Each 5 ml dose delivers the corresponding amount of Ramipril.

Ramipril oral solution is typically prescribed for patients who have difficulty swallowing capsules, including older patients, those with swallowing disorders, patients with learning disabilities, or anyone who finds solid oral dosage forms difficult to manage. It may also be prescribed when a more precise dose measurement in a smaller increment is needed. The doses available in the oral solution match those of Ramipril capsules, so switching between formulations at an equivalent dose is straightforward, though this should always be confirmed with your prescriber or pharmacist.

Ramipril oral solution works through the same mechanism as Ramipril capsules, acting on the renin-angiotensin system to lower blood pressure.

Ramipril as a Prodrug

Ramipril is a prodrug. After absorption from the gastrointestinal tract, the liver converts Ramipril to Ramiprilat, the active form. Ramiprilat inhibits the angiotensin-converting enzyme (ACE), which is responsible for converting angiotensin I to angiotensin II. By blocking ACE, Ramiprilat prevents the formation of angiotensin II, a hormone that would otherwise cause blood vessels to narrow and the body to retain sodium and water. With less angiotensin II, blood vessels remain relaxed, circulating volume decreases slightly, and blood pressure falls.

Cardiovascular and Renal Protection

Beyond blood pressure control, Ramipril reduces the risk of cardiovascular events including heart attack and stroke in patients at high cardiovascular risk, based on evidence from the HOPE trial. In patients with symptomatic heart failure, reducing the workload on the heart through ACE inhibition improves symptoms and outcomes. In patients with type 2 diabetes and microalbuminuria, Ramipril slows the progression of kidney disease by reducing pressure inside the kidney's filtering units. These mechanisms are the same whether Ramipril is taken as a capsule or as an oral solution.

The bioavailability of Ramipril oral solution is comparable to that of Ramipril capsules, meaning the amount of active drug absorbed is broadly similar between formulations. Your prescriber and pharmacist will ensure the correct equivalent dose when switching between formulations.

Always take Ramipril oral solution exactly as your prescriber instructs. The information below summarises key points from the current UK SmPC. Read the Patient Information Leaflet supplied with your specific product before starting treatment.

• Measure each dose carefully using the oral syringe or measuring device provided with the medicine. Never use a household teaspoon, as this does not give an accurate measurement.
• Ramipril oral solution can be taken with or without food. The SmPC for Ramipril does not require it to be taken before food, unlike perindopril erbumine.
• Take Ramipril oral solution once daily, at approximately the same time each day.
• You may mix the measured dose with a small amount of water or other non carbonated liquid to make it easier to take. Check the Patient Information Leaflet for your specific product to confirm what liquids are suitable.
• If you miss a dose, take it as soon as you remember on the same day. If you only remember the following day, skip the missed dose and continue with your normal schedule. Do not take two doses on the same day.
• Do not stop taking Ramipril oral solution without speaking to your prescriber first. Stopping an ACE inhibitor suddenly can cause blood pressure to rise again or worsen heart failure symptoms.

Your prescriber will usually start you at a low dose and increase it over time based on your blood pressure response, kidney function, and potassium levels. Attend all follow up appointments so your treatment can be monitored safely. Kidney function and potassium may be checked periodically during treatment.

Dosage and Strengths Available

Ramipril oral solution 2.5 mg/5 ml is the strength available through this service. Each 5 ml contains 2.5 mg of Ramipril.

Ramipril Oral Solution 2.5 mg/5 ml

Each 5 ml of this solution contains 2.5 mg of Ramipril. This is the strength available through this service. A 2.5 mg dose is commonly used as a starting dose for hypertension when extra caution is needed, such as in older patients, those taking diuretics, or those at risk of a significant blood pressure drop with the first dose. It can also be used as a maintenance dose in patients who achieve adequate blood pressure control at this level.

For patients who require a higher dose, such as 5 mg or 10 mg once daily, a different strength of Ramipril oral solution would need to be prescribed. Dose escalation from 2.5 mg is based on blood pressure response and is decided by your prescriber. If your blood pressure is not adequately controlled at 2.5 mg, your prescriber may increase the dose at your next review appointment.

Side Effects and Safety Information

Ramipril oral solution contains the same active ingredient as Ramipril capsules and has the same side effect profile. The information below is based on the current UK SmPC. Refer to the Patient Information Leaflet for the full list.

• Common Side Effects (may affect up to 1 in 10 people)
• Dry, persistent cough. This is the most frequently reported side effect of Ramipril and all ACE inhibitors. It results from bradykinin accumulation caused by ACE inhibition. It can occur at any time during treatment and is a reason many patients switch to an ARB such as losartan.
• Dizziness or lightheadedness, particularly on standing up quickly
• Headache

Fatigue

• Uncommon Side Effects (may affect up to 1 in 100 people)
• Nausea, vomiting, or diarrhoea
• Raised blood potassium (hyperkalaemia)
• Changes in kidney function, particularly in patients with pre existing kidney disease

Skin rash

Serious Side Effects: Seek Urgent Medical Attention

• Go to your nearest accident and emergency department or call 999 immediately if you experience:
• Angioedema: sudden swelling of the face, lips, tongue, or throat. This is rare but potentially life threatening and is a class effect of all ACE inhibitors. Throat swelling can obstruct breathing and requires immediate emergency care. If you have had angioedema from any ACE inhibitor before, you must not take Ramipril.
• Signs of severely raised potassium such as muscle weakness, an irregular heartbeat, or confusion

A marked fall in urine output, which may indicate acute kidney injury

Report any suspected side effect to your prescriber, pharmacist, or via the MHRA Yellow Card scheme at yellowcard.mhra.gov.uk.

Who Can Take Ramipril Oral Solution?

• Ramipril Oral Solution May Be Suitable If You:
• Are an adult with a confirmed diagnosis of hypertension, symptomatic heart failure, or another condition for which Ramipril is licensed
• Have difficulty swallowing capsules or tablets and require a liquid antihypertensive formulation
• Are already prescribed Ramipril capsules and your prescriber or pharmacist has recommended switching to the oral solution for ease of administration

Are already prescribed Ramipril oral solution and require a repeat prescription through an online prescribing service

• Ramipril Oral Solution Is Not Suitable If You:
• Are pregnant or planning to become pregnant. Ramipril is contraindicated in pregnancy. ACE inhibitors cause serious harm to the developing baby, particularly in the second and third trimesters. Contact your prescriber immediately if you become pregnant while taking Ramipril oral solution.
• Are breastfeeding
• Have a history of angioedema related to previous ACE inhibitor treatment, or hereditary or idiopathic angioedema
• Have severe kidney impairment or are on dialysis
• Are taking aliskiren and have diabetes or moderate to severe kidney impairment
• Have a known allergy or hypersensitivity to Ramipril, any other ACE inhibitor, or any excipient in the oral solution formulation
• Are under 18 years of age (this online service is for adults)

The drug interactions for Ramipril oral solution are the same as for Ramipril capsules. Tell your prescriber about all medicines you take. Key interactions include:

• Potassium supplements, potassium-sparing diuretics (such as spironolactone or amiloride), and potassium-containing salt substitutes: these can raise blood potassium to dangerous levels when combined with Ramipril.
• NSAIDs such as ibuprofen: regular use can reduce the blood pressure lowering effect of Ramipril and increase the risk of kidney problems.
• Lithium: Ramipril can increase lithium blood levels. Close monitoring is required.
• Diuretics: combining Ramipril with a diuretic increases the risk of a significant blood pressure drop, particularly with the first dose.
• Aliskiren: contraindicated in combination with Ramipril in patients with diabetes or significant kidney impairment.

Your prescriber will review all current medicines during the clinical assessment before any prescription is considered.
