Pentoxifylline ER 400 mg An Overview
Pentoxifylline is a medication that belongs to a class of drugs known as xanthine derivatives. It is primarily used for the treatment of various conditions related to impaired blood flow, particularly those affecting peripheral arteries and veins. In its extended-release formulation, Pentoxifylline ER 400 mg is designed to provide a sustained therapeutic effect, improving patient compliance and minimizing side effects.
Mechanism of Action
The therapeutic effects of pentoxifylline stem from its ability to increase the flexibility of red blood cells and reduce blood viscosity. This leads to improved microcirculation and oxygen delivery to tissues, especially in areas affected by chronic ischemia. By inhibiting platelet aggregation and promoting vasodilation, pentoxifylline enhances blood flow, alleviating symptoms such as pain and cramping in the legs associated with intermittent claudication—a common condition in patients with peripheral artery disease.
Indications
Pentoxifylline ER 400 mg is primarily indicated for the management of intermittent claudication resulting from chronic occlusive arterial disease. Patients suffering from pain, cramping, and fatigue in their limbs can benefit significantly from this treatment. Additionally, pentoxifylline has been used off-label in various conditions, including diabetic foot ulcers, acute respiratory distress syndrome (ARDS), and as an adjunct in the treatment of other vascular diseases.
Dosage and Administration

The recommended dosage of Pentoxifylline ER is typically 400 mg taken three times daily, with or without food. The extended-release formulation allows for a gradual release of the active ingredient, maintaining stable blood levels throughout the day. It is crucial for patients to adhere to their prescribed regimen and not to exceed the recommended dosage, as this could increase the risk of adverse effects.
Side Effects
While pentoxifylline is generally well-tolerated, some patients may experience side effects. Commonly reported adverse effects include gastrointestinal disturbances, such as nausea, vomiting, and diarrhea. Other potential side effects may include headache, dizziness, and flushing. Serious side effects, though rare, can include hypotension, arrhythmias, or severe allergic reactions. Patients should inform their healthcare providers of any pre-existing conditions and all medications they are taking to avoid potential drug interactions.
Contraindications and Precautions
Pentoxifylline should not be used in patients with a known hypersensitivity to the drug or its components. Caution is advised in patients with a history of bleeding disorders, as pentoxifylline can enhance bleeding risk due to its effects on platelet function. Additionally, the use of pentoxifylline during pregnancy or lactation should be considered only if the potential benefits outweigh the risks, as there is limited data on its safety in these populations.
Conclusion
Pentoxifylline ER 400 mg is a valuable therapeutic option for individuals suffering from conditions characterized by poor blood circulation, particularly intermittent claudication. Its ability to enhance microcirculation, promote tissue oxygenation, and improve overall patient quality of life makes it an essential part of the treatment landscape for peripheral vascular diseases. However, as with any medication, thorough consultation with a healthcare professional is vital to ensure safety and efficacy. By understanding its mechanisms, benefits, and potential side effects, patients can make informed decisions about their treatment options.
