What is Trental

PentoxifyllineThe Generic name of this drug
Treatment SummaryPentoxifylline (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

Effectiveness

How Trental Affects PatientsPentoxifylline 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 bodyPentoxifylline 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

Trental Toxicity & Overdose RiskTaking 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.

Trental for Peripheral Vascular Disease
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.

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.
