Naftidrofuryl Capsules (Praxilene): What You Need To Know
Comprehensive guide to naftidrofuryl capsules for improving blood circulation in peripheral vascular diseases.
Naftidrofuryl capsules, marketed as Praxilene®, are a medication designed to improve blood circulation in conditions caused by poor blood flow, such as peripheral vascular disease.
Take naftidrofuryl capsules three times daily with meals, swallowing each one whole with a full glass of water to prevent irritation. Side effects are uncommon but may include nausea, diarrhoea, or skin rash. This guide provides detailed information on its uses, administration, precautions, and more, helping patients manage vascular symptoms effectively.
About naftidrofuryl
Naftidrofuryl is a type of medicine known as a 5HT2 antagonist, primarily used for treating blood circulation problems associated with vascular disease. It is also referred to as naftidrofuryl oxalate or Nafronyl oxalate in some regions, and is available in capsule form.
| Type of medicine | Used for | Also called | Available as |
|---|---|---|---|
| 5HT2 antagonist | Blood circulation problems (vascular disease) | Nafronyl oxalate (in US); Naftidrofuryl oxalate, Praxilene® | Capsules |
Poor blood flow, or peripheral vascular disease, occurs when arteries narrow, reducing oxygen delivery to tissues. This leads to symptoms like leg pain during walking (intermittent claudication), cold extremities, night cramps, rest pain, trophic ulcers, Raynaud’s syndrome, diabetic arteriopathy, acrocyanosis, arteritis, incipient gangrene, and chronic venous ulcers.
Naftidrofuryl works by improving the body’s ability to utilise oxygen in the blood, acting as a vasodilator that widens blood vessels, reduces vascular resistance, and enhances circulation to the limbs. It also has mild antiplatelet effects, preventing clot formation in narrowed vessels, and may promote endothelial nitric oxide release for further dilation. This multifaceted action alleviates pain and cramping, particularly in intermittent claudication, allowing better physical activity and quality of life.
Clinical evidence supports its use in peripheral arterial disease, where it selectively dilates arteries in the limbs, improving symptoms over at least three months of treatment. It is particularly beneficial for elderly patients with these disorders.
Before taking naftidrofuryl
Before starting naftidrofuryl, inform your doctor about your medical history and current medications to ensure safety. Certain conditions require caution or contraindication.
- Kidney issues: Avoid if you have a history of hyperoxaluria or recurrent calcium kidney stones, as naftidrofuryl can modify urine components, promoting oxalate stone formation. Drink plenty of water to maintain diuresis if at risk.
- Heart conditions: Contraindicated in certain cardiac disorders, atrioventricular block, or severe heart failure.
- Liver problems: Use with caution if you have liver dysfunction; monitor for signs of damage like jaundice or unexplained fatigue.
- Pregnancy and breastfeeding: Not recommended due to lack of data; risk is low in elderly users, but consult a doctor.
- Allergies: Do not take if hypersensitive to naftidrofuryl or excipients like magnesium stearate or talc.
- Other medicines: Disclose all prescriptions, over-the-counter drugs, herbals, or supplements, as interactions may occur.
Patients with swallowing difficulties should note capsules must be swallowed whole; crushing is not advised due to oesophagitis risk.[10]
How to take naftidrofuryl
Follow your doctor’s instructions precisely, as detailed in the manufacturer’s leaflet. The typical adult and elderly dose is 100 mg (one capsule) three times daily with meals, for a minimum of three months or as advised. Each capsule contains 100 mg naftidrofuryl oxalate.
- Administration: Swallow capsules whole during or immediately after meals with at least one full glass of water (minimum 200 ml) to avoid oesophagitis, especially before bed.
- Duration: Continue as prescribed; stopping early may reduce benefits. Do not exceed the dose.
- Missed dose: Take as soon as remembered unless near the next dose; do not double up.
- Perioperative advice: Omit on surgery morning due to water volume needed. Post-op, resume only with adequate fluids and diuresis.
Take with food to enhance absorption and minimise stomach upset.
