What it is and what it is used for

for What Iloprost is The active substance of Iloprost 10 microgram/ml nebuliser solution is iloprost. It imitates a natural substance in the body called prostacyclin. Iloprost inhibits unwanted blocking or narrowing of blood vessels and allows more blood to flow through the vessels. What Iloprost is used for Iloprost is used to treat moderate cases of primary pulmonary hypertension (PPH) in adult patients. PPH is a category of pulmonary hypertension where the cause of the high blood pressure is not known. This is a condition where blood pressure is too high in the blood vessels between the heart and the lungs. Iloprost is used to improve exercise capacity (the ability to carry out physical activity) and symptoms. How Iloprost works Breathing in the mist carries Iloprost to the lungs, where it can work most effectively in the artery between heart and lungs. Improved blood flow leads to a better supply of oxygen to the body and reduced strain on the heart.

What you need to know before you take it

e Iloprost Do not use Iloprost

• if you are allergic to iloprost or any of the other ingredients of this medicine (listed in section 6).
• if you are at risk of bleeding – for example, if you have an active ulcer of the stomach or of the first part of the small intestine (duodenal ulcers), if you have suffered a physical injury (trauma), if you are at risk of bleeding within the skull.
• if you have a heart problem, such as:
• Poor blood flow to the heart muscles (severe coronary heart disease or unstable angina). Symptoms can include chest pain.
• A heart attack within the last six months.
• A weak heart (decompensated cardiac failure) which is not under close medical observation.
• Severe unstable heartbeat.
• A defect of the heart valves (inborn or acquired) that causes the heart to work poorly (not related to pulmonary hypertension).
• if you have had a stroke within the last 3 months, or any other occurrence that reduced the blood supply to the brain (e.g. transient ischaemic attack).
• if your pulmonary hypertension is due to a blocked or narrowed vein (venous occlusive disease).

Warnings and precautions Talk to your doctor, pharmacist or nurse before using Iloprost:

• Inhaling Iloprost might trigger breathing difficulties (see section 4), especially in patients with bronchospasm (sudden constriction of the muscles in the walls of the small airways) and wheezing. Tell your doctor if you have a lung infection, severe asthma, or chronic lung disease (chronic obstructive pulmonary disease). Your doctor will monitor you closely.
• Your blood pressure will be checked before treatment and if it is too low (less than 85 mmHg for the upper value) then therapy with Iloprost should not be started.
• In general, you will need to take special care to try and avoid effects of low blood pressure, such as fainting and dizziness: − Tell your doctor if you are taking any other medication because the combined effect with Iloprost may lower your blood pressure further (see below "Other medicines and Iloprost"). − Stand up slowly when you get out of chairs or bed. − If you tend to faint as soon as you get out of bed, it may be helpful to take your first dose of the day while you are still lying down. − If you tend to experience fainting episodes, avoid any exceptional straining, for example during physical exertion; it might be useful to inhale Iloprost before. Fainting episodes may be due to the underlying disease. Tell your doctor if they get worse. He/she may consider adjusting your dose or changing your treatment.
• If you suffer from a weak heart condition such as right heart failure, and feel that your disease is worsening, tell your doctor. Symptoms can include swelling of feet and ankles, shortness of breath, palpitations, urinating more frequently at night or oedema. Your doctor will consider changing your treatment.
• If you experience difficulty breathing, cough up blood, and/or sweat excessively these may be signs that you have water in the lungs (lung oedema). Stop using Iloprost and tell your doctor immediately. He/she will look for the cause and take appropriate measures.
• If you have liver problems or very severe kidney problems, requiring dialysis, tell your doctor. You may be gradually introduced to the prescribed dose or be prescribed a lower dose of Iloprost than for other patients (see section 3. "How to use Iloprost"). Contact of Iloprost with skin or swallowing Iloprost
• Do NOT let Iloprost solution come into contact with your skin or eyes. If it does, rinse the skin or your eyes immediately with plenty of water.
• Do NOT drink or swallow Iloprost solution. If you swallow it accidentally, drink plenty of water and tell your doctor. Children and adolescents The safety and efficacy of iloprost in children aged up to 18 years have not been established. Other medicines and Iloprost Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines. Iloprost and certain other medicines may affect each other in the way they work in your body. Tell your doctor if you are taking:
• Medicines used to treat high blood pressure or heart disease, such as:
• Beta blockers.
• Nitro-vasodilators.
• ACE inhibitors. Your blood pressure may drop much further. Your doctor may change the dosage.
• Medicines that thin the blood or inhibit blood clotting, this includes
• Acetylsalicylic acid (ASA – a compound found in many medicines that lower fever and relieve pain).
• Heparin.
• Coumarin-type anticoagulants, such as warfarin or phenprocoumon.

• Non-steroidal anti-inflammatory drugs.
• Non-selective phosphodiesterase inhibitors such as pentoxifylline.
• Selective phosphodiesterase 3 (PDE 3) inhibitors, such as cilostazol or anagrelide.
• Ticlopidine;
• Clopidogrel.
• Glycoprotein IIb/IIIa antagonists, such as:
• Abciximab.
• Eptifibatide.
• Tirofiban.
• Defibrotide. Your doctor will monitor you carefully. Before taking any medicine ask your doctor or pharmacist, who has more information on medicines to be careful with or avoid when using Iloprost. Iloprost with food and drink Food or drink is not expected to affect Iloprost. However, you should avoid taking food or drink during inhalation. Pregnancy
• If you suffer from pulmonary hypertension, avoid getting pregnant as pregnancy may lead to a worsening of your condition and may even endanger your life.
• If you could get pregnant, use reliable contraception from the time you start treatment and during treatment.
• If you are pregnant, think you may be pregnant or are planning to have a baby, tell your doctor straight away. Iloprost should only be used during pregnancy if your doctor decides that the potential benefit outweighs the potential risk to you and the foetus. Breast-feeding It is not known whether Iloprost passes into human milk. A potential risk to the breast-feeding child cannot be excluded and it is preferable to avoid breastfeeding during iloprost therapy. Ask your doctor or pharmacist for advice before taking any medicine. Newborns, infants and pregnant women should not be in the same room while you are inhaling Iloprost. Driving and using machines Iloprost lowers blood pressure and may cause dizziness or light-headedness in some people. Do not drive or operate any tools or machines if you feel these effects. Iloprost contains ethanol This medicine contains 0.78 mg of alcohol (ethanol) in each ampoule which is equivalent to 0.81 mg 96% ethanol (v/v). The amount in 1 ml of this medicine is equivalent to less than 1 ml beer or 1 ml wine. The small amount of alcohol in this medicinal product will not have any noticeable effects.

of pulmonary hypertension. How much to inhale and for how long Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure. The dose of Iloprost and the duration of treatment that is right for you depend on your individual condition. Your doctor will advise you. Do not change the recommended dose without consulting your doctor first. Different nebuliser devices can be used to administer Iloprost. Depending on the type of device used and dose prescribed, 1 ml or 2 ml of iloprost are appropriate. Breelib nebuliser If you are starting Iloprost treatment or if you switch from an alternative device your first inhalation will be with Iloprost 10 microgram/ml. If you tolerate this dose well, your next dose should be increased using another available presentation on the market containing 20 microgram/ml of iloprost. You should continue on this dose. If you cannot tolerate inhalation of this higher dose talk to your doctor who may decide that you should take Iloprost 10 microgram/ml. Most people will have 6 to 9 inhalation sessions spread throughout the day. One inhalation session with Breelib will usually last about 3 minutes. Your doctor will supervise your treatment when you start using the Breelib nebuliser to ensure that you tolerate the dose and speed of inhalation well. I-Neb AAD nebuliser In general, when starting Iloprost treatment the first inhaled dose should be 2.5 microgram iloprost as delivered at the mouthpiece. If you tolerate this dose well, your dose should be increased to 5 microgram iloprost and you should continue on this dose. If you are unable to tolerate the 5 microgram dose, the dose should be reduced to 2.5 microgram. Most people will have 6 to 9 inhalation sessions spread throughout the day. One inhalation session will usually last about 4 to 10 minutes with I-Neb AAD depending on the prescribed dose. Venta-Neb nebuliser (2 ampoules of Iloprost) In general, when starting Iloprost treatment the first inhaled dose should be 2.5 microgram iloprost as delivered at the mouthpiece. If you tolerate this dose well, your dose should be increased to 5 microgram and you should continue on this dose. If you are unable to tolerate the 5 microgram dose, the dose should be reduced to 2.5 microgram. Most people will have 6 to 9 inhalation sessions spread throughout the day.

The following information is intended for healthcare professionals only: Instructions for use and handling Patients stabilised on one nebuliser should not switch to another nebuliser without close supervision by the treating doctor as different nebulisers have been shown to produce aerosols with slightly different physical characteristics and may have faster delivery of the solution (see section 5.2 of the Summary of Product Characteristics). To minimise accidental exposure, it is recommended to keep the room well ventilated. Breelib When using the Breelib nebuliser please follow the instructions for use provided with the device.

I-Neb AAD The I-Neb AAD System is a portable, hand-held, vibrating mesh technology nebuliser system. This system generates droplets by ultrasound, which forces the solution through a mesh. The I-Neb AAD nebuliser has also been shown to be suitable for the administration of iloprost 10 mcg/ml. The measured MMAD of the aerosol droplets was 2.1 micrometres. This nebuliser monitors the breathing pattern to determine the aerosol pulse time required to deliver the pre-set dose of 2.5 or 5 microgram iloprost. The dose delivered by the I-Neb AAD system is controlled by the medication chamber in combination with a control disc. Each medication chamber is colour coded and has a corresponding colour coded control disc:

• For the 2.5 microgram dose the medication chamber with the red latch is used together with the red control disc.
• For the 5 microgram dose the medication chamber with the purple coloured latch is used together with the purple control disc.

If you have kidney or liver problems There is no need to alter the dose in patients with mild or moderate kidney problems (patients with a creatinine clearance >30 ml/min). If you have very severe kidney problems and require dialysis or if you have liver problems, your doctor will introduce you to Iloprost gradually and possibly prescribe fewer daily inhalations. Start therapy by inhaling 2.5 microgram iloprost using 1 ml ampoule of Iloprost. Use dosing intervals of 3 – 4 hours (this corresponds to a maximum of 6 administrations per day). Thereafter, your doctor may cautiously shorten the dosing intervals depending on how you tolerate the treatment. If your doctor decides to further increase the dose up to 5 microgram, again dosing intervals of 3 – 4 hours should be chosen initially and shortened depending on how you tolerate the treatment. If you feel that the effect of Iloprost is too strong or too weak, talk to your doctor or pharmacist. Ask your doctor to have someone help you become thoroughly familiar with the use of the nebuliser. You should not switch to another nebuliser without consulting the doctor who is treating you. How to inhale For each inhalation session you should use a new ampoule of Iloprost. Just before you start to inhale, break the glass ampoule and pour the solution into the medication chamber following the instructions for use of the nebuliser. Follow carefully the instructions that come with the nebuliser especially the instructions on hygiene and cleaning of the nebuliser. Always take Iloprost exactly as your doctor has told you.

• Iloprost nebuliser solution is inhaled using the nebulisers your doctor prescribed (either the Breelib, the Venta-Neb or the I-Neb AAD system).
• The nebuliser turns Iloprost solution into a mist which you breathe in through your mouth.
• For the inhalation you should use a mouthpiece to prevent Iloprost coming into contact with your skin. Do not use a facial mask.
• Follow carefully any instructions that come with the nebuliser. Check with your doctor or pharmacist if you are unsure.
• Any Iloprost solution remaining in the nebuliser after inhalation must be thrown away (see section 5). Room ventilation Be sure to ventilate or air the room in which you have taken your Iloprost treatment. Other people might accidentally be exposed to Iloprost through the room air. In particular, newborns, infants and pregnant women should not be in the same room while you are inhaling Iloprost. Breelib Fill the medication chamber with Iloprost immediately before use.
