Effectiveness

How Pentoxifylline Affects PatientsPentoxifylline is a synthetic drug related to theophylline and caffeine that is used to treat peripheral arterial disease (PAD). It can improve circulation, reduce inflammation, and act as an antioxidant. However, it can also cause heart problems such as angina, arrhythmia, and low blood pressure. If taken with warfarin, it should be monitored closely to prevent bleeding. People with risk factors that increase their risk of bleeding, such as retinal bleeding or recent surgery, should also be monitored.

How Pentoxifylline works in the bodyPentoxifylline works in the body to lower the thickness of the blood and reduce inflammation. It does this by blocking an exporter protein from binding to molecules that suppress tumors and cause inflammation, forcing them to stay in the cell and work to kill it or stop it from reproducing. Pentoxifylline also increases the flexibility of erythrocytes, reduces plasma fibrinogen, and stops neutrophils from activating. Additionally, it suppresses erythrocytes and platelets from forming clumps, and it can decrease pro-inflammatory molecules while increasing anti-inflammatory molecules like interleukin-

Pentoxifylline Reviews: What are patients saying about Pentoxifylline?

Pentoxifylline for Peripheral Vascular Disease

I was in incredible pain due to 100% artery blockage in my left leg and 70% in my right leg. My old doctor friend prescribed pentoxiflline and it began working within a few weeks. I now take two 400mg pills in the morning and two at night, with no side effects. This medication has allowed me to live a relatively normal life, playing golf three times per week at age 88. I'm curious about how long I can safely take this drug, but so far it has been an absolute lifesaver.

The first half hour after taking this medication, I have felt very dizzy and nauseous. However, I have also noticed less pain in my legs, so I'll continue to take it and hope that my body adjusts to the medicine.

I had a pretty serious blockage in my left leg, and after six weeks of treatment with pentoxifylline, the pain finally went away. I'm now two months pain-free and fingers crossed that it'll stay that way.

Pentoxifylline for Peripheral Vascular Disease

I just finished the first month and it's too soon to tell if this is working. It's not like Zantac where you take it and heartburn goes away in 30 minutes. Trental takes time to build up in the tissues. I'll have to give it a couple more months before deciding if it's worth continuing with this treatment or trying something else.
