Drug Uses

Trental is used to treat intermittent claudication (pain, cramping, numbness, or weakness in the foot, hip, thigh, or buttocks) in certain patients.. It might also be used by your doctor in other cases as he deems fit.


Following the dosage instructions of your doctor is the best way to use any medication. If you are unsure or do not remember the instructions then you may read the medicine label for more detailed information.

You may choose to take Trental with a meal or milk.

You should swallow it whole and not break, crush or chew it.

Drug Class and Mechanism

Trental is classified as a xanthine derivative blood flow enhancer. It thins the blood and improves flexibility, thereby enabling the blood to flow more freely through the veins.

Missed Dose

Despite your best attempts at remembering, if you still miss out on a dose, then take it as soon as you remember about it. But keep in mind that you will have to adjust your next dose by spacing it out by 4 to 5 hours. If this is not possible, then the best thing to do would be to skip the missed dose and continue with your normal dosage schedule.

Never try to compensate for the missed dose by taking a double dose together. It may cause adverse effects.


Store Trental at room temperature, (between 68 and 77 degrees F (20 and 25 degrees C). Always keep it in a cool dark place that is not directly exposed to sources of heat or moisture and sunlight. Protect it from kids and pets.
