1. What is Thiopental VUAB and what is it used for

Thiopental VUAB is a powder for solution for injection that contains thiopental sodium as the active substance in a quantity of 500 mg or 1000 mg. Thiopental VUAB is an anesthetic from the barbiturate group and is used:

• as a single anesthetic agent for short surgical procedures,
• for the induction of general anesthesia before the use of other anesthetic agents,
• as a supplement to local anesthesia,
• to provide a hypnotic effect during balanced anesthesia using other agents administered to achieve an analgesic or muscle relaxant effect,
• to control convulsive states during or after inhalation anesthesia, local anesthesia, or occurring for other reasons,
• in patients after neurosurgical procedures with increased intracranial pressure, provided that adequate ventilation is ensured.

Thiopental VUAB should only be used by specialists in the field of anesthesiology.

2. Important information before using Thiopental VUAB

When not to use Thiopental VUAB

If the patient has any of the following conditions:

• allergy to thiopental sodium or other barbiturates (medicines used in patients with convulsions and for anesthesia) or any of the other components of this medicine (listed in section 6);
• porphyria (a severe disease caused by a disorder of hemoglobin synthesis);
• expected difficulties in maintaining the patency of the upper airways and lack of equipment for immediate resuscitation;
• asthmatic status (life-threatening breathing difficulties caused by bronchial constriction);
• difficulty waking up after anesthesia that has occurred in the past.

In the case of rectal administration of the medicine:

• tumors and inflammatory diseases of the intestines;
• local inflammatory conditions or irritation of the anus;
• severe thrombocytopenia (significantly reduced platelet count).

Warnings and precautions

Before starting to use Thiopental VUAB, you should discuss it with your doctor. During the use of Thiopental VUAB, access to equipment and medicines for resuscitation, endotracheal intubation, and oxygen should be ensured, and the patient's airways should be kept open at all times.

Thiopental VUAB may only be used with special caution in the following cases:

• hypovolemia (low blood volume due to blood or fluid loss);
• cardiovascular diseases (heart muscle disease, valve stenosis, pericarditis, tamponade, congestive heart failure, coronary heart disease, QT interval prolongation, and heart block, high resting potential, or myocardial ischemia) and other circulatory system diseases (malignant hypertension);
• hypotension (low blood pressure) or shock (sudden circulatory failure);
• obstructive respiratory disease (breathing difficulties caused by bronchial constriction, e.g., in asthma or chronic obstructive pulmonary disease);
• impaired respiratory function, airway obstruction;
• liver or kidney disease;
• muscle weakness or atrophy (myasthenia gravis, myotonic dystrophy);
• metabolic disorders (myxedema, adrenal insufficiency);
• endocrine disorders (including hyperpituitarism, hyperthyroidism, hyperadrenalism, or hyperinsulinism);
• paralysis or weakness of the eye muscles;
• abscess of the oral cavity, sepsis (general infection of the body);
• obesity.

Before administering Thiopental VUAB, you should inform your doctor if any of the above conditions apply to the patient, as it may be necessary to adjust the dose.

Thiopental VUAB can only be used if all the preliminary conditions have been met, including the availability of personnel and equipment to treat any potential emergencies, such as respiratory failure and respiratory arrest.Special caution should be exercised when using Thiopental VUAB in clinical conditions where the hypnotic effect may be prolonged or enhanced (e.g., excessive premedication, Addison's disease, increased blood urea levels, severe anemia). If the injection is accidentally administered into an artery or outside a vein, tissue necrosis (death) or very painful nerve inflammation may occur. The use of Thiopental VUAB may cause dependence.

Thiopental VUAB and other medicines

You should tell your doctor, pharmacist, or nurse about all the medicines the patient is currently taking or has recently taken, including those available without a prescription. The following medicines affect the action of Thiopental VUAB or Thiopental VUAB affects their action:

3. How to use Thiopental VUAB

The medicine is administered by a doctor in a hospital. The medicine should be used in accordance with the recommended dosages below or as recommended by the doctor. The dose of Thiopental VUAB should be adjusted individually for each patient depending on their age, sex, weight, and desired depth of anesthesia. The concentrations of the medicine used for intravenous administration are from 2.5% to 5.0%. The 2.5% (500 mg in 20 mL) concentration is most commonly used. The 5% (500 mg in 10 mL) solution is used in exceptional cases.

Use in anesthesia

Healthy adults 4 - 6 mg/kg body weight Children and infants 5 - 7 mg/kg body weight Elderly patients 2 - 3 mg/kg body weight

Use in convulsive states

Immediately after the onset of convulsions, 75 mg to 125 mg (3 mL to 5 mL of 2.5% solution) should be administered.

Use in patients after neurosurgical procedures with increased intracranial pressure

Thiopental VUAB is administered in intermittent bolus doses of 1.5 to 3 mg/kg body weight. The maximum single dose is 1 g. The maximum daily dose is 2 g. It is recommended to administer a small "test" dose of 25 to 75 mg (1 to 3 mL of 2.5% solution) intravenously to assess tolerance or check if the patient is not hypersensitive to thiopental, and then discontinue the administration of the medicine to observe the patient's reaction for about 60 seconds. Thiopental VUAB is administered intravenously only in adult patients, and in children also rectally. Thiopental VUAB should only be used by anesthesiology specialists. The medicine is administered by slow injection to limit respiratory depression and the possibility of overdose.

Using a higher dose of Thiopental VUAB than recommended

Thiopental VUAB is administered by a doctor or under the supervision of a doctor, so it is unlikely that the patient will receive too much of this medicine. Nevertheless, if the patient has received a higher dose of Thiopental VUAB than they should have, they may experience a sudden drop in blood pressure, which can lead to shock. Additionally, overdose may cause breathing difficulties (respiratory arrest), which can be life-threatening without connection to artificial respiration. In case of any further doubts about the use of this medicine, you should consult a doctor.

Like all medicines, Thiopental VUAB can cause side effects, although not everybody gets them. Frequent(may occur in up to 1 in 10 patients):

• slow heart rate, low blood pressure, heart rhythm disorders;
• shallow breathing with decreased frequency, leading to respiratory arrest, difficult breathing (bronchospasm), laryngospasm, cough;
• feeling of coldness/shivering.

Frequency not known(frequency cannot be estimated from the available data):

• sudden, life-threatening allergic reactions affecting the whole body (anaphylactic reactions).
• low potassium levels in the blood during the administration of the medicine and high potassium levels in the blood after discontinuation of the medicine.

After rectal administration of the medicine, the following side effects may occur: anal irritation, uncontrolled bowel movement, prolonged drowsiness, nausea, vomiting, clumsiness.
