1. What is Treprostinil Zentiva and what is it used for

What is Treprostinil Zentiva

The active substance of this medicine is treprostinil.

Treprostinil belongs to a group of medicines whose action is similar to that of natural prostacyclins. Prostacyclins are hormone-like substances that reduce blood pressure by relaxing blood vessels, so they widen and allow blood to flow more easily. Prostacyclins can also prevent blood clotting.

What Treprostinil Zentiva is used for

Treprostinil is used to treat idiopathic or hereditary pulmonary arterial hypertension (PAH) in patients with moderate symptoms. Pulmonary arterial hypertension is a disease where the blood pressure is too high in the blood vessels between the heart and the lungs. This causes difficulty breathing, dizziness, tiredness, fainting, palpitations or abnormal heartbeats, dry cough, chest pain, and swelling of the ankles or legs.

Treprostinil is initially administered by continuous subcutaneous infusion (under the skin). Some patients may not tolerate this administration because it causes them local pain and swelling. The doctor will decide whether Treprostinil Zentiva can be administered to them by continuous intravenous infusion directly into a vein with the insertion of a central venous tube (catheter) connected to an external pump. Your doctor will determine which option is best for you.

How Treprostinil Zentiva works

Treprostinil reduces blood pressure in the pulmonary artery by improving circulation and reducing the heart's workload. Improved blood flow increases oxygen supply to the body and requires less effort from the heart, so it works more efficiently. Treprostinil improves symptoms associated with PAH and the ability to exercise in patients with reduced activity.

2. What you need to know before you use Treprostinil Zentiva

Do not use Treprostinil Zentiva:

• if you are allergic to treprostinil or any of the other ingredients of this medicine (listed in section 6);
• if you have been diagnosed with a disease called "pulmonary veno-occlusive disease". In this disease, the blood vessels that carry blood through the lungs become swollen and blocked, which increases the pressure in the blood vessels between the heart and the lungs;
• if you have severe liver failure;
• if you have a heart problem, for example:

• a heart attack (myocardial infarction) in the last six months,
• severe changes in heart rate,
• severe coronary heart disease or unstable angina,
• a diagnosed heart defect, such as a faulty heart valve that causes the heart to malfunction,
• any untreated or closely monitored heart disease;

• if you have a high specific risk of bleeding, for example, due to active stomach ulcers, injuries, or other bleeding disorders;
• if you have had a stroke in the last 3 months or any interruption of blood supply to the brain.

Warnings and precautions

Talk to your doctor before starting Treprostinil Zentiva:

• if you have any liver disease;
• if you have been told you are clinically obese (BMI over 30 kg/m2);
• if you have human immunodeficiency virus (HIV) infection;
• if you have high blood pressure in the liver veins (portal hypertension);
• if you have a congenital heart defect that affects the way blood flows through it.

During treatment with this medicine, tell your doctor:

• if your blood pressure drops (hypotension);
• if you experience a rapid increase in breathing difficulties or persistent cough (may be related to pulmonary congestion, asthma, or other disease), consult your doctor immediately;
• if you experience excessive bleeding, as treprostinil may increase the risk by preventing blood clotting;
• if you have a fever while receiving treprostinil intravenously, or if the infusion site becomes red, swollen, or painful to the touch, as it may be a sign of infection.

Other medicines and Treprostinil Zentiva

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

Tell your doctor if you are taking:

• medicines to treat high blood pressure(antihypertensive medicines or other vasodilators)
• medicines used to increase the amount of urine produced(diuretics), including furosemide
• medicines that interrupt blood clotting(anticoagulants), such as products containing warfarin, heparin, or nitric oxide
• any non-steroidal anti-inflammatory drug (NSAID) (such as acetylsalicylic acid or ibuprofen)
• medicines that may increase or decrease the effect of treprostinil (such as gemfibrozil, rifampicin, trimethoprim, deferasirox, phenytoin, carbamazepine, phenobarbital, St. John's Wort), as your doctor may need to adjust the dose of treprostinil.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor for advice before taking this medicine.

Treprostinil is not recommended during pregnancy, unless your doctor considers it essential. The safety of this medicine for use during pregnancy has not been established.

3. How to use Treprostinil Zentiva

Follow the instructions for administration of this medicine exactly as indicated by your doctor. If you are unsure, consult your doctor again.

Treprostinil Zentiva is administered as a continuous infusion:

• subcutaneously (under the skin) through a small tube (cannula) placed in the abdomen or thigh; or,
• intravenously through a tube (catheter) that is usually placed in the neck, chest, or groin.

In both cases, treprostinil will be delivered through the tube by an external portable pump.

Before leaving the hospital or clinic, your doctor will tell you how to prepare treprostinil and at what speed the pump should deliver the treprostinil.

Flushing the infusion tube while it is connected can cause an accidental overdose.

In any case, you will also be given information on how to use the pump correctly and what to do if it stops working. The information should also tell you who to contact in case of an emergency.

Treprostinil is diluted only when administered with continuous intravenous infusion.

For intravenous infusion with an external portable pump:The treprostinil solution should only be diluted with sterile water for injection or 0.9% sodium chloride solution for infusion (as indicated by your doctor).

Adult patients

Treprostinil Zentiva is available as a solution for infusion of 1 mg/ml, 2.5 mg/ml, 5 mg/ml, or 10 mg/ml. Your doctor will determine the infusion rate and the suitable dose for your disease.

Overweight patients

If you are overweight (weigh 30% or more of your ideal body weight), your doctor will determine the initial and subsequent doses based on your ideal body weight. See also section 2, "Warnings and precautions".

Elderly patients

Your doctor will determine the infusion rate and the suitable dose for your disease.

Use in children and adolescents

There are limited data available for children and adolescents.

Dose adjustment

The infusion rate in each individual patient may be reduced or increased only under medical supervision.

The goal of adjusting the infusion rate is to establish an effective maintenance rate that improves the symptoms of PAH while minimizing side effects.

If your symptoms worsen or if you need complete rest, or are confined to bed or a chair, or if any physical activity causes discomfort and your symptoms appear at rest, do not increase the dose without consulting your doctor. It may be that treprostinil is no longer sufficient to treat your disease and you need another treatment.

How can bloodstream infections be avoided during intravenous administration of treprostinil?

As with any long-term intravenous treatment, there is a risk of contracting bloodstream infections. Your doctor will tell you how to avoid them.

If you use more Treprostinil Zentiva than you should

If treprostinil is accidentally administered in excess, you may experience nausea, vomiting, diarrhea, low blood pressure (dizziness, fainting), flushing, and/or headache.

If any of these symptoms become severe, you should contact your doctor or hospital immediately. The doctor may reduce the dose or interrupt the administration until the symptoms disappear. Then, the administration of Treprostinil Zentiva will be resumed with the dose recommended by your doctor.

In case of overdose, consult your doctor immediately or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medicine and the amount used.

If you stop treatment with Treprostinil Zentiva

Always use treprostinil as indicated by your doctor or hospital specialist. Do not stop using treprostinil unless your doctor tells you to.

Sudden interruption or rapid reduction of the treprostinil dose may cause PAH to recur, with the possibility of rapid and severe deterioration of your condition.

If you have any further questions on the use of this medicine, ask your doctor.
