1. What is Sedaconda and what is it used for

This medicine contains the active substance isoflurane, which belongs to a group of medicines called anesthetics. It is used to provide sedation (a state of calmness, drowsiness, or sleep) in adult and pediatric patients from 3 years of age who require mechanical ventilation (a treatment with special machinery that helps patients breathe) during their stay in intensive care.

2. What you need to know before you start using Sedaconda

Do not use Sedaconda

• If you are allergic to isoflurane or other halogenated anesthetics.
• If you or a family member have ever experienced a rapid rise in body temperature during sedation or anesthesia (a rare condition known as malignant hyperthermia). For more information, see the section "Possible side effects".

Warnings and Precautions

Talk to your doctor or nurse before you start using this medicine if:

• You have ever had a prolonged QT interval (abnormal electrocardiogram reading), or Torsades de Pointes(potentially life-threatening irregular heartbeat). Isoflurane has been known to cause these conditions on some occasions.
• You have a mitochondrial disease. Mitochondrial diseases are a group of rare genetic disorders that occur when the mitochondria (small cellular structures) do not produce enough energy for the body to function properly.
• You have heart disease (e.g., coronary heart disease).
• You have been given an inhaled anesthetic before, especially in the last 3 months. This may increase the risk of liver damage.
• You have increased intracranial pressure (pressure around the brain) due to brain injury, brain tumor, or other condition. Sedaconda may further increase the pressure inside the skull.
• You have low blood pressure, low blood volume, or are weak. You may need a lower dose of Sedaconda.
• You have liver disease.
• You have a condition that affects your nerves and muscles (a neuromuscular disease, e.g., Duchenne muscular dystrophy or myasthenia gravis).
• You are taking muscle relaxant medications (see section "Other medicines and Sedaconda").

Sedaconda may cause malignant hyperthermia, a rapid and significant rise in body temperature accompanied by muscle stiffness and other symptoms (see section 4).

Sedaconda may cause hyperkalemia (elevated serum potassium levels) in rare cases (see section 4). Patients with neuromuscular disease seem to be the most vulnerable.

Sedaconda may cause breathing difficulties (respiratory depression) (see section 4).

Children and Adolescents

This medicine must not be given to children under 3 years of age, as experience with this medicine is limited in this age group.

Other Medicines and Sedaconda

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

This is especially important if you are taking any of the following medicines:

• Certain medicines for depression, called non-selective monoamine oxidase inhibitors (MAOIs), such as isocarboxazid, nialamide, phenelzine, etc. Your doctor will not give you Sedaconda for at least 15 days after taking MAOIs.
• Medicines called beta-sympathomimetics (a broad group of medicines that affect the part of the nervous system that works automatically), such as isoprenaline, adrenaline, noradrenaline. Taking these medicines with Sedaconda may cause irregular heartbeats.
• Medicines called indirect-acting sympathomimetics, such as amphetamines and their derivatives, psycho-stimulants, appetite suppressants, ephedrine, and its derivatives. Taking these medicines with Sedaconda may cause high blood pressure.
• Beta-blockers (a group of medicines used to treat high blood pressure and certain heart diseases). Taking these medicines with Sedaconda may affect cardiac compensation reactions (reactions that help your body compensate for the reduced blood supply and oxygen caused by heart failure).
• Isoniazid (an antibiotic used to treat tuberculosis), which may increase the risk of liver damage.
• Calcium channel blockers (used to treat high blood pressure and certain heart diseases), such as amlodipine, diltiazem, nifedipine, verapamil.
• Opioids (e.g., morphine, fentanyl), benzodiazepines (e.g., midazolam, diazepam), and other sedative medicines, which may cause slow and ineffective breathing.
• Medicines used to relax muscles (e.g., suxamethonium, pancuronium, atracurium, vecuronium). Sedaconda may increase their effects.

Pregnancy, Breast-feeding, and Fertility

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

Sedaconda may cause increased blood loss, for example, if you are going to have a uterine operation or give birth. Your doctor will not give you this medicine unless the potential benefit outweighs the potential risks for you and your baby.

If you have been breast-feeding before receiving Sedaconda, you must stop breast-feeding until the medicine has been eliminated from your body. Your doctor will tell you when it is safe for you to continue breast-feeding.

Driving and Using Machines

This medicine may affect your ability to drive and use machines for up to 6 days.

Do not drive or use machines until your doctor tells you it is safe to do so.

3. How to Use Sedaconda

Sedaconda will only be given to you by qualified and experienced medical personnel. The doctor will decide the correct dose for you based on your age, health condition, and the level of sedation (drowsiness) you need.

The doctor will give you the correct starting dose to achieve the required level of sedation, carefully observing your responses and vital signs (such as pulse, blood pressure, and breathing, etc.).

Sedaconda is a liquid that turns into vapor (gas) using a vaporizer. It is for inhalation use, which means you will breathe it in as a vapor.

If you receive more Sedaconda than you should

If you are given too much Sedaconda and are in deep sedation, your blood pressure may drop (hypotension) and your breathing may be slow and ineffective. The doctor will take supportive measures to correct blood pressure and breathing.

If you have any further questions about the use of this medicine, ask your doctor, pharmacist, or nurse.

4. Possible Side Effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Side effects of unknown frequency (cannot be estimated from the available data):

• high blood sugar or potassium levels,
• mood changes,
• mental deterioration and convulsions, a medical condition in which the body's muscles contract and relax rapidly and repeatedly, resulting in uncontrolled body movements,
• irregular heartbeats, slow heartbeats, cardiac arrest (a condition in which the heart suddenly stops beating), prolonged QT interval (abnormal electrocardiogram reading) and Torsades de Pointes (potentially life-threatening irregular heartbeats),

This information is intended only for healthcare professionals:

Sedaconda 100% Liquid for Vapor Inhalation

Administration

Sedaconda should only be administered and inhaled through the Sedaconda ACD Administration Device, using the Sedaconda Filling Adapter, and should only be used with intubated or tracheotomized patients with protected airways. Sedaconda should only be administered by medical personnel familiar with the management of patients with mechanical ventilation, with Sedaconda ACD, and with the pharmacodynamics of isoflurane.

Isoflurane should only be administered in an adequately equipped environment, by trained personnel in the management of volatile anesthetic agents. To minimize leaks and spills during the use of Sedaconda, adequate general ventilation in the intensive care room, as well as a well-designed exhaust system, appropriate work practices, and routine equipment maintenance, should be ensured.

Sedaconda ACD is a modified passive heat and moisture exchanger (HME) and, as such, adds dead space to the respiratory circuit. The patient's ventilatory status should be taken into account when selecting the size of Sedaconda ACD; refer to the instructions for use provided with Sedaconda ACD.

Complete information on how to use Sedaconda ACD and the Sedaconda Filling Adapter is presented in the Instructions for Use document provided with the devices.

Read the Sedaconda package leaflet and the Instructions for Use provided with Sedaconda ACD and the Sedaconda Filling Adapter before configuring the Sedaconda ACD administration system and starting sedation.
