What is Trental ER?

Trental ER is an oral extended release tablet made up of a miscellaneous coagulation modifier called pentoxifylline. We carry both the brand name Trental ER and the generic alternative, which is sold as pentoxifylline. Both are available as 400mg doses!

Trental ER is a medication used to help treat a condition called intermittent claudication, as well as reducing some of its symptoms. This condition causes pain which is a result of insufficient blood flow to muscles during time of exercise. Commonly, this pain in located in the legs after walking for a certain amount of time at a certain pace. It is called intermittent claudication because the pain is not constant; it only occurs from the start to the end of exercise, but can end up becoming more severe and cause pain during time of rest as well.

Trental ER (pentoxifylline) is effective at treating intermittent claudication because of its ability to change your blood to help it flow easier through narrow blood vessels which helps increase the amount of oxygen that can be carried through blood when the muscles need more (like during exercise).

What is Pentoxifylline?

Trental ER (Pentoxifylline) is a medication that is used to improve symptoms found in a blood flow problem that is usually located in the legs and arms, otherwise known as intermittent claudication due to occlusive artery disease. This medication is known to also decrease the muscle aches, pains, and cramps during exercising, which also includes walking, that occurs with intermittent claudication.  When you begin to take this medication, it generally works by helping the flow of blood move more easily through any narrowed arteries, thus increasing the amount of oxygen that can be delivered by the blood when your muscles need it the most. Therefore, this medication can help increase the distance and duration you can walk. This medication comes in the singular dose of 400mg. If you have any questions regarding this medication or any inquiries in general, feel free to give us a call at our toll free number 1-877-385-8998.
