6. Contents of the package and additional information

Adempas contains the active ingredient riociguat, a guanylate cyclase (GCs) stimulator that acts by widening the blood vessels that go from the heart to the lungs.

Adempas is usedinthe treatment of certain forms of pulmonary hypertension in adults and children, a disease in which these blood vessels constrict, making it more difficult for the heart to pump blood through them and causing an increase in blood pressure in these vessels. Because the heart has to work harder than normal, people with pulmonary hypertension feel tired, dizzy, and have difficulty breathing.

By widening the constricted arteries, Adempas improves the ability to perform physical activity, that is, to walk a greater distance.

Adempas is used in these two types of pulmonary hypertension:

• Chronic thromboembolic pulmonary hypertension (CTEPH)

The Adempas tablets are used to treat CTEPH in adult patients. In CTEPH, the blood vessels of the lung are blocked or constricted by blood clots. Adempas can be used in patients with CTEPH in whom a surgical intervention cannot be performed or in those patients in whom the pulmonary hypertension persists or recurs after surgery.

• Certain types of pulmonary arterial hypertension (PAH)

The Adempas tablets are used to treat PAH in adults and children under 18 years of age with a body weight of at least 50kg. In PAH, the wall of the blood vessels of the lungs is thickened and the vessels have constricted. Adempas is only indicated in some forms of PAH, such as idiopathic PAH (in which the cause of PAH is unknown), hereditary PAH, and PAH caused by connective tissue disorders. Your doctor will check these aspects. Adempas can be taken alone or with other medications used in the treatment of PAH.

Do not take Adempas if:

−You takephosphodiesterase type 5 (PDE5) inhibitors(such as sildenafil, tadalafil, vardenafil). These are medications for treating high blood pressure in the pulmonary arteries (PAH) or erectile dysfunction;

• tieneserious liver problems(severe hepatic insufficiency);

− areallergicto riociguat or any of the other components of this medication (including those listed in section 6);

− arepregnant;

−You takenitratesornitric oxide donors(such as amyl nitrite) in any form, medications commonly used to treat high blood pressure, chest pain, or heart disease. This also includes recreational drugs known as “poppers”;

• You take othermedications similar to Adempas (soluble guanylate cyclase stimulators, such as vericiguat). Consult your doctor if you are unsure;
• You havelow blood pressure(systolic blood pressure:in children aged6to <12years old below 90mmHg, in patients≥12yearsbelow<95>
• You have anincrease in blood pressurein the lungs associated with pulmonary fibrosis, of unknown cause (idiopathic pulmonary fibrosis).

If you have any of these conditions,talk to your doctorfirst and do not take Adempas.

Warnings and precautions

Consult your doctor or pharmacist before starting Adempas if:

• You have recently had asevere pulmonary hemorrhage;
• You have received treatment to stop amassive bleeding(bronchial arterial embolization);
• You are takingblood thinners(anticoagulants) as this may cause bleeding in the lungs. Your doctor will perform regular blood tests and blood pressure measurements;
• You experiencedifficulty breathing, as this may be caused by fluid accumulation in the lungs. Talk to your doctor if this occurs;

You have any symptoms oflow blood pressure(hypotension) such as dizziness, vertigo, or fainting, or if you are taking medications to lower blood pressure or medications that cause an increase in urination, or if you have heart or circulation problems. Your doctor may decide to monitor your blood pressure. If you are over 65 years old, you have a higher risk of developing low blood pressure;

• You are ondialysisor yourkidneys do not function properly(creatinine clearance <30
• tienemild liver problems(mild hepatic insufficiency);
• You start or stopsmokingduring treatment with this medication, as this may affect the level of riociguat in the blood.
