1. What is Trepulmix and what is it used for

What is Trepulmix

The active substance of Trepulmix is treprostinil.

Treprostinil belongs to a group of medicines that work in a similar way to natural prostacyclins. Prostacyclins are hormone-like substances that lower blood pressure by relaxing blood vessels, making them wider and allowing blood to flow more easily. Prostacyclins may also prevent blood from clotting.

What is Trepulmix used for

Trepulmix is used to treat adult patients with chronic thromboembolic pulmonary hypertension (CTEPH) that cannot be operated on or in patients with persistent or recurrent CTEPH after surgical treatment (classified as WHO functional class III or IV), to improve exercise capacity and symptoms of the disease. Chronic thromboembolic pulmonary hypertension is a condition where blood pressure is too high in the blood vessels between the heart and lungs, causing shortness of breath, dizziness, tiredness, fainting, palpitations or irregular heartbeats, dry cough, chest pain, and swollen ankles or legs.

How Trepulmix works

Trepulmix reduces blood pressure inside the pulmonary artery by improving blood flow and reducing the amount of work the heart has to do. By improving blood flow, it increases oxygen supply to the body and reduces stress on the heart, making it work more efficiently. Trepulmix improves symptoms associated with CTEPH and exercise capacity in patients with activity limitations.

2. What you need to know before you use Trepulmix

Do not use Trepulmix

• 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"; This is a disease where the blood vessels that carry blood through the lungs become swollen and blocked, causing higher pressure in the blood vessels between the heart and lungs;
• if you have severe liver disease;
• if you have a heart problem, such as:

• a heart attack (myocardial infarction) in the last 6 months;
• severe irregular heartbeat;
• severe ischemic heart disease or unstable angina;
• a heart defect, such as a faulty heart valve that makes the heart work poorly;
• any heart disease that is not being treated or is not under close medical supervision.
• • if you have a high risk of bleeding, such as active stomach ulcers, wounds, or other bleeding conditions;
  • if you have had a stroke in the last 3 months or any other interruption of blood supply to the brain.

Warnings and precautions

Talk to your doctor before starting Trepulmix if you:

• have liver disease;
• have kidney disease;
• have been told you are medically obese (BMI over 30 kg/m2);
• are on a low-sodium diet.

During treatment with Trepulmix, tell your doctor:

• if your blood pressure drops (hypotension);
• if you experience a rapid increase in breathing difficulties or persistent cough (this may be related to congestion in the lungs, asthma, or other conditions), consult your doctor immediately;
• if you experience excessive bleeding, as treprostinil may increase the risk by preventing blood from clotting.

Children and adolescents

Trepulmix should not be used in children and adolescents.

Other medicines and Trepulmix

Tell your doctor if you are taking, have recently taken, or might take any other medicines. Tell your doctor if you are taking:

• medicines used to treat high blood pressure(antihypertensive medicines or other vasodilators);
• medicines used to increase urination(diuretics), including furosemide;
• medicines that prevent blood clotting(anticoagulants) such as warfarin, heparin, or nitric oxide products;
• any non-steroidal anti-inflammatory drug (NSAID) (e.g., acetylsalicylic acid or ibuprofen);
• medicines that may increase or decrease the effects of Trepulmix (e.g., gemfibrozil, rifampicin, trimethoprim, deferasirox, phenytoin, carbamazepine, phenobarbital, hypericum), as your doctor may need to adjust the dose of Trepulmix.

It is recommended to use contraceptive methods during treatment with treprostinil.

If you are pregnant, breastfeeding, think you may be pregnant, or plan to become pregnant, ask your doctor for advice before taking this medicine.

3. How to use Trepulmix

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

Trepulmix is administered undiluted by continuous subcutaneous infusion (under the skin) through a small tube (cannula) in your abdomen or thigh;

Trepulmix is driven through the tube by a portable pump.

Before you leave the hospital or clinic, your doctor will tell you how to prepare Trepulmix and the rate at which the pump should administer treprostinil. You will also be given information on how to use the pump correctly and what to do if it stops working. You will also be told who to contact in case of an emergency.

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

Adult patients

Trepulmix 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 dose suitable for your condition.

Elderly patients

No special dose adjustment is needed in these patients.

Patients with severe liver or kidney disease

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

Infusion rate

The infusion rate can be reduced or increased individually only under medical supervision.

The goal of adjusting the infusion rate is to establish an effective maintenance rate that improves the symptoms of CTEPH while minimizing adverse reactions.

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

If you use more Trepulmix than you should

If you accidentally overdose on Trepulmix, you may experience nausea, vomiting, diarrhea, low blood pressure (dizziness, lightheadedness, or fainting), flushing of the skin, and/or headache.

If any of these effects worsen, you should contact your doctor or hospital immediately. Your doctor may reduce or interrupt the infusion until your symptoms have disappeared. The Trepulmix solution for infusion will be reintroduced at the dose recommended by your doctor.

If you stop treatment with Trepulmix

Always use Trepulmix following the instructions of your doctor or hospital specialist. Do not stop using Trepulmix unless your doctor has told you to.

Sudden withdrawal or rapid reduction of the dose of Trepulmix can cause pulmonary hypertension to return, with the possibility of rapid and severe worsening of your condition.

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