1. What is Tiopental Panpharma and what is it used for

Tiopental Panpharma is a medicine used for anesthesia from the barbiturate group.
Tiopental Panpharma is used:

• For short-term anesthesia without intubation (short-term anesthesia during surgical procedures that do not require any preparation for artificial respiration),
• For induction of general anesthesia with or without intubation (induction of longer anesthesia during surgical procedures with preparation of the patient for artificial respiration or without such preparation).

Note:As with all barbiturates, it is necessary to administer a pain reliever
during anesthesia with Tiopental Panpharma.

2. Important information before using Tiopental Panpharma

Tiopental Panpharma should not be used if the patient:

• is allergic to sodium thiopental and sodium carbonate or other barbiturates (medicines that are similar in chemical structure to Tiopental Panpharma and are used in patients with convulsions and for anesthesia) or any of the other ingredients of this medicine (listed in section 6),
• has acute alcohol poisoning, sleeping pills, painkillers, and psychotropic drugs (medicines used to treat mental disorders),
• has porphyria (a severe disease caused by a disorder of hemoglobin synthesis), malignant hypertension (very high blood pressure), shock (sudden circulatory failure), and status asthmaticus (life-threatening breathing difficulties caused by narrowing of the small airways).

If any of these conditions apply to the patient, they should tell their doctor or
nurse. Usually, they will decide to use a different medicine.

Warnings and precautions

Before starting to take Tiopental Panpharma, the patient should discuss it with their doctor or
pharmacist.
Tiopental Panpharma can only be used under certain conditions and with special caution. The patient should ask their doctor for detailed information. This also applies to situations where this information has applied to the patient in the past.
Tiopental Panpharma may only be used with special caution in the following cases:

• obstructive respiratory disease (breathing disorders due to narrowing of the airways, e.g., in bronchial asthma),
• hypovolemia (low blood volume due to blood or fluid loss),
• severe heart muscle damage,
• severe kidney or liver dysfunction,
• in infants,
• metabolic disorders, including diabetes.

The patient should inform their doctor if any of the above apply to them.
In such cases, Tiopental Panpharma can only be used if all preliminary conditions are met, including the availability of personnel and specialized equipment for the treatment of potential emergencies, such as respiratory failure and respiratory arrest.
There is a risk of severe low blood pressure in the event of rapid injection (e.g., bolus injection). Therefore, Tiopental Panpharma should be administered slowly. Tiopental Panpharma is not intended for continuous infusion. Tissue necrosis has been observed after prolonged administration of Tiopental Panpharma in infusion lasting more than a few hours.
If the injection is accidentally given into an artery or outside a vein, tissue necrosis (death) or very painful nerve inflammation may occur. The entire arm should be immobilized, and the doctor must take all measures to aspirate the previously injected solution using a permanently inserted cannula. The healing process can be accelerated by applying wet dressings, if possible soaked in alcohol. In the case of larger volumes, drugs that accelerate diffusion (e.g., hyaluronidase) can be used. Additionally, the adjacent perivenous area can be soaked with a 1% novocaine solution. To dilute the medicinal product Tiopental Panpharma that has penetrated the tissues, an isotonic sodium chloride solution should be administered subcutaneously.

Children

During diagnostic or therapeutic procedures in the upper respiratory tract, hyperreflexia (increased reflexes) and laryngospasm (stridor) can be expected,
especially in children.

Tiopental Panpharma and other medicines

The patient should tell their doctor, pharmacist, or nurse about all medicines they are currently taking or have recently taken, including those bought without a prescription.
The following medicines affect Tiopental Panpharma:

• In combined therapy with other medicines that have a depressant effect on the central nervous system (e.g., benzodiazepines) or when used with alcohol, it should be considered that such use may cause additional depressant effects on the central nervous system. For the same reason, in combined therapy with other medicines that have a depressant effect on the respiratory center (such as opioids), additional depressant effects on the respiratory center may occur.

Furthermore, substances that compete with Tiopental Panpharma for binding to plasma proteins, such as sulfonamides, may enhance the effect of Tiopental Panpharma and lead to a reduction in the required induction dose.

• Tiopental Panpharma affects other medicines:
• If Tiopental Panpharma is used repeatedly at short intervals, it may have an inducing effect on liver enzymes. This may lead to accelerated breakdown of other medicines, such as coumarin derivatives, corticosteroids, and oral contraceptives, and consequently reduce their effectiveness.
• Additionally, it increases the toxic effect of methotrexate.

Using Tiopental Panpharma with food, drink, and alcohol

Before and after anesthesia, under no circumstances should the patient consume any drinks or food containing alcohol.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor, pharmacist, or nurse before using this medicine.
Tiopental Panpharma passes through the placenta. Therefore, general anesthesia with Tiopental Panpharma in pregnant women can only be used if it is absolutely necessary and after a thorough assessment of the risk and benefits.
Tiopental Panpharma passes into human milk. The concentrations of this medicinal product in the blood of breastfed infants may be higher than in the mother due to immature metabolism. Tiopental Panpharma is detected in human milk up to 36 hours after injection. During this period, the patient should not breastfeed.

Driving and using machines

After administration of anesthesia with Tiopental Panpharma, the patient's ability to react quickly and appropriately to unexpected and sudden events may be impaired. Therefore, the patient should not drive a car or other vehicle after outpatient surgery.
The patient should return home under supervision and under no circumstances consume alcohol.
The patient should ask their doctor to explain how long to take these precautions. During this time, patients should not operate any electrical devices or machines or perform any work without a stable support point.

Tiopental Panpharma contains sodium

Tiopental Panpharma 500 mg powder for solution for injection contains 53 mg of sodium (the main component of common salt) per vial. This corresponds to 2.65% of the maximum recommended daily intake of sodium in the diet for adults.
Tiopental Panpharma 1 g powder for solution for injection contains 106 mg of sodium (the main component of common salt) per vial. This corresponds to 5.3% of the maximum recommended daily intake of sodium in the diet for adults.

3. How Tiopental Panpharma is administered

This injection is given by a doctor in a hospital. The medicine should be used in accordance with the recommended dosage instructions below or as recommended by the doctor.
Tiopental Panpharma should only be used when qualified personnel and necessary specialized equipment for resuscitation and endotracheal intubation are available to treat potential medical emergencies, such as respiratory failure and respiratory arrest.
The recommended dose is determined based on the individual patient's sensitivity and the desired depth of anesthesia. The following information provides general guidelines; the safest way to achieve optimal effect is by slow, repeated administration of small doses.
For induction of general anesthesia, the dose for intravenous injection is usually 5 mg of Tiopental Panpharma per kilogram of body weight. The duration of action is from 6 to 8 minutes. Typically, a dose of 100 to 200 mg of thiopental sodium is injected slowly over 20 seconds.
Administration of additional doses depends on the patient's sensitivity and the desired depth of anesthesia.
In the case of short-term anesthesia, the total dose should not be greater than twice the induction dose of 100 to 200 mg of thiopental sodium.
The total dose required for a surgical procedure may be from 400 mg to 1 g of thiopental sodium.

Elderly patients

Due to the slowed metabolism in elderly patients, an increased effect of the medicinal product should be expected. Therefore, the dose should be reduced accordingly.

Use in patients with kidney or liver disease

In patients with impaired liver or kidney function, the dose of the medicine must be adjusted according to the degree of impairment.

In case of overdose of Tiopental Panpharma

Treatment of overdose is symptomatic and should be carried out in intensive care and by qualified medical personnel or the treating physician. Nevertheless, in case of overdose, the following side effects may occur.
If the patient has received a higher dose of Tiopental Panpharma than they should have, they may experience a sudden drop in blood pressure, which can lead to shock. As a result of inadequate blood pumping by the heart, pulmonary edema may occur. A drop in blood pressure may also result from an allergic reaction; however, such a reaction usually occurs in combination with allergic skin reactions.
Additionally, overdose may cause breathing difficulties (persistent respiratory failure or respiratory arrest), which can be life-threatening without connecting the patient to artificial respiration. There is a sudden decrease in body temperature.
If the patient has any further questions about the use of the medicine, they should ask their doctor or pharmacist.

4. Possible side effects

If the patient experiences any of the following symptoms, they should immediately tell their doctor - they may need urgent medical attention:
difficulty breathing, wheezing, rash, hives, and dizziness. This may be a severe allergic reaction (frequency not known, cannot be estimated from the available data).
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Since Tiopental Panpharma is practically always administered in combination with other anesthetics, it is not always possible to determine which of the anesthetics actually caused the observed side effects.
The patient should tell their doctor or nurse immediately if they notice any of the following side effects.
Common(may affect up to 1 in 10 people):
Breathing difficulties with short apneas
Hiccup during spontaneous breathing and mask ventilation
Increased well-being and vivid dreams, sometimes nightmares
Allergic reactions, e.g., bronchial asthma and laryngospasm
Redness and swelling of the skin.
Very rare(may affect up to 1 in 10,000 people) include:

• Severe allergic reactions with sudden and severe conditions threatening cardiac arrest (sudden lack of heart activity) and respiratory arrest (lack of breathing)
• Allergic reactions associated with a decrease in the number of red blood cells due to premature destruction of cells along with kidney damage.

Frequency not known(frequency cannot be estimated from the available data):
Nausea and vomiting (caused by another medicine given in combination)
Coughing and sneezing
Pain at the injection site after intravenous injection
Formation of blood clots
Phlebitis.

Information intended only for healthcare professionals:

Tiopental Panpharma, 500 mg, powder for solution for injection

Tiopental Panpharma, 1 g, powder for solution for injection

Special precautions for disposal and preparation of the medicine for administration

Tiopental Panpharma should not be mixed with other solutions for injection and infusion (except for those listed below). Additionally, the reconstituted solution should not be administered with other solutions for injection or infusion. Solutions prepared with Tiopental Panpharma have a strongly alkaline pH and are incompatible with volume expanders and anesthetic adjuvants with an acidic pH, as precipitation and clogging of the needle during injection may occur. For the same reason, chemical changes in the added solution cannot be ruled out.
Preparation of the solution for injection:
Tiopental Panpharma 500 mg and 1 g is used as a 2.5% and 5% solution for injection.
In the case of a 2.5% solution for injection, the contents of one vial of Tiopental Panpharma 500 mg should be dissolved in 20 mL of water for injections or 0.9% sodium chloride solution.
In the case of a 5% solution for injection, the contents of one vial of Tiopental Panpharma 500 mg should be dissolved in 10 mL of water for injections or 0.9% sodium chloride solution.
In the case of a 2.5% solution for injection, the contents of one vial of Tiopental Panpharma 1 g should be dissolved in 40 mL of water for injections or 0.9% sodium chloride solution.
In the case of a 5% solution for injection, the contents of one vial of Tiopental Panpharma 1 g should be dissolved in 20 mL of water for injections or 0.9% sodium chloride solution.
Method of administration
In the case of anesthesia injection, Tiopental Panpharma is dissolved in water for injections or 0.9% sodium chloride solution and then slowly injected intravenously.
Several injections can be administered.
In a few cases, acute tolerance has been demonstrated, i.e., it may be necessary to administer a larger dose after the first effective anesthetic dose to repeat the same effect. On the other hand, if subsequent doses are administered, it should be remembered that the substance accumulates.
No solution of this medicinal product should be administered if a precipitate is visible. Solutions should be used immediately after preparation.
Any unused medicinal product or waste material should be disposed of in accordance with local regulations.
Overdose:
The typical symptom of overdose is a sudden decrease in blood pressure, which can lead to shock. As a result of inadequate blood pumping by the heart, pulmonary edema may occur. A drop in blood pressure may also result from an allergic reaction; however, such a reaction usually occurs in combination with allergic skin reactions.
Overdose may cause persistent respiratory failure or respiratory arrest, which can be life-threatening without connecting the patient to artificial respiration. There is a sudden decrease in body temperature.
Treatment of overdose is symptomatic and should be carried out in intensive care and by qualified medical personnel or the treating physician. Nevertheless, in case of overdose, the following side effects may occur.
Treatment with infusion of volume expanders is indicated as a measure to counteract the decrease in blood pressure and as an anti-shock measure. Dopamine (from 2 to 5 μg/kg/min) or norepinephrine (noradrenaline from 0.1 to 0.2 μg/kg/min) can be added to the infusion solution. The body temperature should be brought back to normal.
