1. What Trental is and what it is used for

Trental contains the active substance "pentoxifylline", which belongs to a class of medicines known as "peripheral vasodilators".
It works by dilating the peripheral blood vessels that carry blood to the legs and arms.
Trental is indicated for the treatment of skin lesions called chronic venous ulcers due to damage to the veins.

2. What you should know before taking Trental

Do not take Trental

  • if you are allergic to pentoxifylline, to other similar medicines (methylxanthines), or to any of the other ingredients of this medicine (listed in section 6);
  • if you have recently had a heart attack;
  • if you have had severe blood loss (serious haemorrhage), because there is a risk that Trental may lead to increased bleeding;
  • if you have had bleeding from the retina (extensive retinal haemorrhage), because there is a risk that Trental may lead to increased bleeding;
  • if you are pregnant (see Pregnancy and breastfeeding).

Warnings and precautions
Talk to your doctor or pharmacist before taking Trental.
At the first signs of an allergic reaction (anaphylactic/anaphylactoid), stop taking Trental immediately and inform your doctor.
Your doctor will monitor you carefully if you:

  • have low blood pressure (hypotension);
  • have impaired kidney function (see section "How to take Trental");
  • have severely impaired liver function;
  • have an increased tendency to bleeding (haemorrhage), for example due to treatment with medicines that inhibit blood clotting (anticoagulants) or due to blood clotting disorders (see also "Do not take Trental");
  • have serious disturbances in heart rhythm (cardiac arrhythmias);
  • are taking pentoxifylline together with anti-vitamin K medicines or platelet aggregation inhibitors used for clotting disorders (see Other medicines and Trental);
  • are taking pentoxifylline together with medicines for diabetes (see Other medicines and Trental);
  • are taking pentoxifylline together with the antibiotic ciprofloxacin (an anti-infective medicine; see Other medicines and Trental);
  • are taking pentoxifylline together with theophylline, a medicine used to treat asthma.

If you develop retinal bleeding (haemorrhage) while being treated with Trental 400 mg, your doctor will discontinue treatment.
Children and adolescents
There are no data on the use of Trental in children.
Other medicines and Trental
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
The effects of Trental may be influenced by, or may influence, the following medicines:

  • insulin and oral medicines used for diabetes (oral antidiabetics): Trental may enhance the blood glucose-lowering effect of these medicines. If you are being treated with these medicines for diabetes mellitus, your doctor will monitor you closely;
  • anti-vitamin K medicines (used to make the blood less viscous): Trental may enhance the anticoagulant effect of these medicines. If you are also taking anti-vitamin K medicines, your doctor will monitor you;
  • medicines used to treat high blood pressure (antihypertensives) or that lower blood pressure as a side effect: Trental may enhance the effect of these medicines;
  • theophylline (used to treat asthma): Trental may in some cases increase theophylline levels and, consequently, the occurrence of adverse effects;
  • ketorolac tromethamine (a medicine used for inflammation): concomitant use with Trental may increase the risk of bleeding;
  • ciprofloxacin (an antibiotic used for infections): in some patients, it may increase the amount of Trental in the blood, possibly leading to an increase in both the number and severity of adverse effects;
  • platelet aggregation inhibitors (medicines that prevent platelet aggregation and thus thrombus formation): due to the increased risk of bleeding, Trental should be administered cautiously when used together with a platelet aggregation inhibitor (such as clopidogrel, eptifibatide, tirofiban, epoprostenol, iloprost, abciximab, anagrelide, NSAIDs other than selective COX-2 inhibitors, acetylsalicylates [acetylsalicylic acid/lysine acetylsalicylate], ticlopidine, dipyridamole);
  • cimetidine (a medicine used to treat stomach ulcers): may increase the levels of Trental and its active metabolite in the blood.

Pregnancy and breastfeeding
If you are pregnant, think you may be pregnant, are planning to become pregnant, or are breastfeeding, consult your doctor or pharmacist before taking this medicine.
Pregnancy
Trental is contraindicated during pregnancy because there is insufficient clinical experience with the use of this medicine in pregnancy.
Breastfeeding
If you are breastfeeding, your doctor will decide whether to discontinue breastfeeding and start treatment, or to continue breastfeeding and avoid administering Trental.
Driving and using machines
Trental does not impair the ability to drive or operate machinery.

3. How to take Trental

Take this medicine exactly as directed by your doctor or pharmacist. If
you have any doubts, consult your doctor or pharmacist.
The recommended dose is:
1 tablet of Trental 400 mg, 2-3 times daily.
Your doctor may decide to adjust the recommended dose.
Swallow the tablets after meals with some liquid and without chewing.
For successful treatment, regular administration and prolonged therapy are important.

If you have liver problems (hepatic impairment)
Your doctor will reduce your Trental dose if you have severe liver disease.

If you have heart or blood circulation problems (cardiovascular disorders)
Treatment should be started at a low dose if you have low blood pressure (hypotension), if you are at risk of a drop in blood pressure (for example, if you have blood vessel disorders affecting blood supply to the heart or a significant narrowing of the vessels supplying blood to the brain), or if you have blood circulation disorders. In these cases, your doctor will increase the dose only gradually.

If you take more Trental than you should
If you take more Trental than prescribed, you may experience the following symptoms: nausea, dizziness, increased heart rate, or low blood pressure. Additionally, fever, restlessness, sensation of warmth and facial flushing, loss of consciousness, loss of reflexes (areflexia), seizures with muscle spasms (tonic-clonic seizures), and blackish vomit (coffee-ground vomiting), indicating gastrointestinal bleeding, may occur.
There is no known specific antidote. If overdose has occurred recently, your doctor or healthcare provider may take measures to prevent further absorption of the medicine into the bloodstream (e.g. gastric lavage) or to delay its absorption (e.g. activated charcoal).
In case of accidental ingestion or overdose of Trental, contact your doctor immediately or go to the nearest hospital.
If you have any doubts about how to use this medicine, consult your doctor or pharmacist.

  • if you are allergic to pentoxifylline, to other similar medicines (methylxanthines), or to any of the other ingredients of this medicine (listed in section 6);
  • if you have recently had a heart attack;
  • if you have experienced significant blood loss (severe haemorrhage), as there is a risk that Trental may increase bleeding;
  • if you have had bleeding from the retina (extensive retinal haemorrhage), as there is a risk that Trental may increase bleeding;
  • if you are pregnant (see "Pregnancy and breastfeeding");
  • if you suffer from severe arterial disorders of the brain (cerebral sclerosis) or of the heart (coronary sclerosis) associated with increased blood pressure;
  • if you suffer from severe heart rhythm disorders (arrhythmias).

In cases of advanced atherosclerosis, intra-arterial injection into the carotid artery must be avoided.
Warnings and precautions
Talk to your doctor, pharmacist, or nurse before taking Trental.
At the first signs of an allergic reaction (anaphylactic/anaphylactoid), stop immediately the
administration of Trental and inform your doctor.
Your doctor will monitor you particularly closely if you:

  • have low blood pressure (hypotension);
  • have impaired kidney function (see "How to take Trental");
  • have severely impaired liver function;
  • have an increased tendency to bleed (haemorrhage), for example due to treatment with medicines that inhibit blood coagulation (anticoagulants) or due to blood clotting disorders (see "Do not take Trental");
  • are particularly at risk of developing low blood pressure (e.g. if you have severe coronary artery disease, the vessels supplying blood to the heart, or severe narrowing of vessels supplying blood to the brain), because intravenous or intra-arterial injection of Trental may cause a transient drop in blood pressure, possibly leading to collapse and pain due to reduced oxygen supply to the heart (angina-like symptoms);
  • are taking pentoxifylline together with anti-vitamin K medicines or platelet aggregation inhibitors used for coagulation disorders (see "Other medicines and Trental");
  • are taking pentoxifylline together with antidiabetic medicines (see "Other medicines and Trental");

The following information is intended exclusively for physicians or healthcare professionals:
Warnings and precautions
In advanced arteriosclerosis, avoid injection into the carotid artery.
Before starting parenteral treatment (i.v. or intra-arterial), it is advisable to assess individual responsiveness by slowly administering half a vial (2.5 ml = 50 mg), diluted in 10 ml of physiological saline.
In heart failure where compensation with glycosides is required, Trental should not be infused with large volumes of fluid.
If extensive retinal hemorrhages occur during treatment with Trental, therapy must be discontinued.
Preparation and handling of the product
Administration by intravenous infusion:
At the beginning of treatment, the daily dose is 1 vial (100 mg) infused in 250–500 ml of sodium chloride physiological solution or, for example, Ringer's solution, over 120–180 minutes. The dose may subsequently be increased by 1 vial per day up to 300 mg.
If other solutions are used for dilution, their compatibility must be verified individually; only clear solutions may be infused.
In severe cases, if tolerability is good, the daily dose may be gradually increased by 1 vial per day up to 600 mg, administered in two infusions (morning and afternoon), each in 250–500 ml of carrier solution over 120–180 minutes.
If, for practical or tolerability reasons, only one daily infusion can be administered, it is recommended to supplement with 3 (2 + 1) Trental 400 tablets taken orally throughout the day (at noon and in the evening).
Administration by i.v. and intra-arterial route:
1 vial (100 mg) daily, administered slowly with the patient lying down. For intravenous administration, the injection should last at least 5 minutes; for intra-arterial administration, after diluting the vial contents in 20 ml of physiological saline, the injection should be given at a rate of 5 ml every 10 minutes. If tolerated, this administration may be repeated during the same day.
After parenteral treatment, therapy may be continued orally.
It is the physician’s responsibility to determine the dosage, route of administration, and duration of treatment, which may be administered parenterally, orally, or in combination (oral and parenteral simultaneously), depending on the severity of the clinical condition.
Regular administration and prolonged treatment are essential for therapeutic success.
Special populations
Renal impairment
The following dose reductions are required in patients with renal impairment:
Creatinine clearance less than 30 mL/min: 30% – 50% of the dose
Creatinine clearance less than 10 mL/min: 50% – 70% of the dose
Hepatic impairment
Dosage reduction is required, based on individual tolerability, in patients with severe impairment of liver function.
Cardiocirculatory diseases
Treatment should be initiated at low doses in hypotensive patients or those with circulatory instability, as well as in patients particularly at risk of hypotension (e.g., patients with severe coronary artery disease or significant stenosis of vessels supplying the brain); in such patients, the dose should be increased only gradually.
Dilution
For dilution of the solution to be infused, sodium chloride physiological solution or, for example, Ringer's solution may be used. If other solutions are used for dilution, their compatibility must be verified individually; only clear solutions may be infused.
Opening the vial
To open, hold the vial vertically, ensuring the colored mark is facing the user, then push back the upper part of the vial using leverage.
Instructions for opening the vials are shown at the end of this leaflet.
Overdose
Symptoms
Initial symptoms of acute pentoxifylline overdose may include nausea, dizziness, tachycardia, or hypotension. Additional signs may include fever, agitation, sensation of warmth, facial flushing, loss of consciousness, areflexia, tonic-clonic seizures, and coffee-ground vomiting as a sign of gastrointestinal hemorrhage.
Treatment
No specific antidote is known. If ingestion was recent, measures may be taken to prevent further systemic absorption of the active substance (e.g., gastric lavage) or to delay absorption (e.g., activated charcoal).
Management of acute overdose and prevention of complications may require intensive general and specific monitoring, along with implementation of therapeutic measures.
In case of severe drop in arterial pressure, infuse plasma expanders (with caution regarding signs of edema).
Keep airways clear.
Diazepam in case of seizures.
Caution: new-type vial.
