Treatment Summary

Pentoxifylline (PTX) is a medication used to treat intermittent claudication, a condition that causes leg pain due to blocked arteries. It works by improving the flow of blood and also has anti-inflammatory and antioxidant properties. PTX has also been studied for its potential use in treating other conditions like osteoradionecrosis, diabetic kidney disease, and inflammation caused by COVID-19. The drug was first approved by the FDA in 1984, and it is now available in generic forms and under the brand name PENTOXIL.

How Pentoxifylline Affects Patients

Pentoxifylline 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 body

Pentoxifylline 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 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.

Pentoxifylline for Leg Pain when Walking; Absent at Rest

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've been using this treatment for three months and I've found that my mobility has increased by about 25%. I track this progress by measuring the distance between stops when walking. Here's hoping that it continues to be effective!

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.

Pulse Arrival Time for Peripheral Artery Disease

18+
All Sexes
Omaha, NE

1\) The purpose of this study is to assess segmental pulse arrival time (PAT) as an alternative biomarker to detect lower-extremity peripheral artery disease (PAD). The secondary purpose will be to investigate the impacts of age on segmental PAT. The subject population will include any adults 19 years of age or older with or without PAD. Exclusion criteria include having an aortic aneurysm with or without previous intervention, previous revascularization surgeries of the arteries in the legs/aorta, walking impairments independent of PAD, gangrene or ulcers of the toes/feet, and currently pregnant or breastfeeding. 3) All aims of the present study will be completed with a single laboratory visit. Descriptive measurements will include height, weight, age, sex, body fat percentage, and self-reported medication and health history. Subjects will lie in the supine position for 20-min. After rest, either the ankle-brachial index (ABI) or PAT will be assessed. After 10-min of further rest, the other measurement will be performed. ABIs will be assessed according to current guidelines: blood pressures will be assessed in the dorsal pedis and tibialis posterior arteries of both legs and the brachial arteries of both arms using a blood pressure cuff and Doppler ultrasound. PAT will be simultaneously assessed in both arms and legs using an investigational device with a 3-lead electrocardiogram sensor and four photoplethysmography (PPG) sensors. A PPG sensor will be applied to both middle fingers and both big toes. Signals will be collected for 15-min. Thermal images of the fingers and toes will be assessed before and after using the investigational device. After assessment of ABI and PAT, subjects will participate in a 6-min walking test (6MWT) to objectively establish walking capacity. The 6MWT will be performed in accordance with current guidelines. Cones will be separated by 30 meters on a straight flat walkway. Subjects will be instructed to walk back and forth between the cones as fast as they can for 6-min. Subjects will be allowed to rest during the test, if necessary, but the stopwatch will continue to run. Segmental PATs will be compared with ABI and 6-min walking time to determine if segmental PATs can predict lower-extremity PAD (ABI) and the associated walking impairment (6MWT). This study is expected to last \~2hrs. 4) There will be no follow-up.

BR-AC for Venous Leg Ulcers

18+
All Sexes
Guntersville, AL

This study examines a patient population with a non-healing, non-infected venous leg ulcer (VLU) having adequate arterial perfusion with confirmed venous reflux. It is hypothesized that weekly applications of the human placental allograft BioREtain® Amnion Chorion (BR-AC) applied to a non-healing VLU will result in a higher proportion of wounds showing complete healing within 12 weeks of initiating therapy, compared to standard care alone. This study has a crossover period, where subjects on standard care alone who do not achieve complete healing within 12 weeks of initiating therapy will be allowed to crossover to receive BR-AC over 12 additional weeks, to evaluate if their wound can achieve complete healing.
