What is Trental

Pentoxifylline

The Generic name of this drug

Treatment Summary

Pentoxifylline (PTX) is a medication used to improve the flow of blood and also help reduce inflammation. It was originally used to treat intermittent claudication, a type of leg pain in patients with peripheral arterial disease. PTX has been studied for its potential use in other medical conditions, such as osteoradionecrosis, diabetic kidney disease, and any condition associated with fibrosis. Recently, it has been suggested as a possible treatment for COVID-19-related lung complications due to its ability to regulate the production of inflammatory cytokines. Pentoxifylline has been available in Europe since 1972

How Trental Affects Patients

Pentoxifylline is a drug similar to theophylline and caffeine. It is commonly used to treat peripheral arterial disease (PAD), and can have anti-oxidant, anti-inflammatory, and blood-flow regulating effects. It is important to note that people with conditions such as angina, arrhythmia, or hypotension may find pentoxifylline worsens their symptoms. Patients taking warfarin should also be monitored more frequently. Additionally, those with risk factors for bleeding, such as retinal bleeding, peptic ulcers, or recent surgery, should have their blood checked regularly for

How Trental works in the body

Pentoxifylline works by increasing the flexibility of red blood cells, reducing fibrinogen levels in the plasma, and stopping white blood cells from sticking to one another. It also has antioxidant and anti-inflammatory properties. It is believed that pentoxifylline increases the response of an adenosine receptor to adenosine, leading to increased levels of a molecule called cAMP. This cAMP stops the production of pro-inflammatory molecules, increases the production of anti-inflammatory molecules, and reduces the production of molecules that make blood more viscous. Pentoxifylline metabolites have also been shown to reduce superoxide

Risk Level

Description

Abrocitinib

Major

The risk or severity of bleeding and thrombocytopenia can be increased when Pentoxifylline is combined with Abrocitinib.

Riociguat

Major

Pentoxifylline may increase the hypotensive activities of Riociguat.

Abacavir

Minor

Pentoxifylline may decrease the excretion rate of Abacavir which could result in a higher serum level.

Acebutolol

Minor

Pentoxifylline may increase the hypotensive activities of Acebutolol.

Aclidinium

Minor

Pentoxifylline may decrease the excretion rate of Aclidinium which could result in a higher serum level.

Trental Toxicity & Overdose Risk

Taking too much pentoxifylline can cause agitation, fever, redness of the skin, low blood pressure, seizures, drowsiness, and unconsciousness. Treatment should focus on keeping breathing and blood pressure normal, and controlling convulsions. Activated charcoal may be helpful in absorbing the excess drug in the body. People have recovered from overdoses even when taking up to 80 mg/kg.

For those of you looking for info on Trental, I checked into this for my mom. The drug is backordered, but I found nothing which stated from Sanofi-Aventis or the FDA that the drug was discontinued.

Trental for Peripheral Vascular Disease

For three years, this drug has provided great relief from my leg cramping. However, over the last few months, pharmacies have been unable to get it from the manufacturer due to backorders. This is terrible because I rely on this medication to feel better. I don't understand what's going on with the manufacturer that they're not supplying this drug to pharmacies.

Trental for Peripheral Vascular Disease

I've been taking Trental for years with no noticeable side effects. I was recently told by my pharmacist that it had been discontinued, so they gave me Pentoxifylline instead. However, after a few days of taking the new medication, I started getting headaches so I stopped.

Trental for Peripheral Vascular Disease

I've been taking Trental for over a decade now and have never experienced any negative side effects that I'm aware of. Recently though, it hasn't been working as well as it used to. I'm on the highest dose possible, so I don't know if maybe I need to get more exercise or not. All I know is that at night, I often get terrible cramping and pain. And for those of you who are worried about it disappearing from the market, don't worry. It just gets scarce from time to time but it always comes back eventually.

I've been told that Trental and Pentoxifylline are no longer being manufactured. If this is true, it's a real shame because this medication actually works. I tried Plavix once and it gave me terrible pains in my legs.

Trental for Peripheral Vascular Disease

Trental has been a godsend for me. I'm an 81 year old male with very poor circulation in both legs; this has caused severe cramping while walking for over 19 years. Trental helps prevent these cramps, even though I can only walk short distances. I haven't experienced any negative side effects that I know of, and simply take 3 pills with food 3 times per day.

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.
