1. What is Lioresal Intrathecal 10 mg/5 ml and what is it used for

Lioresal Intrathecal 10 mg/5 ml contains the active substance baclofen. Lioresal Intrathecal 10 mg/5 ml is a medicine used for excessive muscle tension.
Lioresal Intrathecal is used to treat severe, chronic spasticity (increased muscle tone) that cannot be effectively treated with standard medicines:

• in multiple sclerosis This is a progressive disease of the nervous system, brain, and spinal cord with physical and mental symptoms.
• after spinal cord injuries or injuries with brain damage
• in other spinal cord diseases

During the qualification phase for treatment and during the dose-increase phase, immediately after pump implantation, the patient will be closely monitored in conditions that ensure access to appropriate equipment and personnel care. Dosing, possible side effects, or signs of infection will be regularly evaluated. The functioning of the drug delivery system will also be checked.
If there is no improvement or the patient feels worse, they should consult a doctor.

2. Important information before using Lioresal Intrathecal 10 mg/5 ml

When not to use Lioresal Intrathecal 10 mg/5 ml:

• if the patient is allergic to baclofen or any of the other ingredients of this medicine (listed in section 6). If the patient thinks they may be allergic, they should consult a doctor.
• if the patient has epilepsy that is resistant to treatment.

Warnings and precautions

The patient should immediately consult a doctor if they think the device is not working properly or if they notice withdrawal symptoms (see withdrawal symptoms in section 3 "How to use Lioresal Intrathecal 10 mg/5 ml").

If possible, a special pump will be implanted under the patient's skin, which will allow for continuous dosing tailored to the patient.
It is very important for the patient to attend scheduled visits, during which the doctor will refill the pump.
If the patient receives too small a dose of Lioresal Intrathecal 10 mg/5 ml, increased muscle tone may return. Muscle spasms may also worsen.
Tell your doctor immediatelyif muscle spasms do not improve or worsen.
The doctor must regularly monitor the patient's condition and the pump's function - at least once a month.

Duration of treatment

The duration of treatment will be decided by your doctor.

How to prepare and administer the medicinal product Lioresal Intrathecal 10 mg/5 ml?

Administration of a test dose, implantation of an infusion pump, and dose increase of the intrathecally administered medicinal product should be performed in a hospital setting, in centers with appropriate experience and under the close supervision of suitably qualified physicians. Immediate access to an intensive care unit should be ensured due to the possibility of severe or life-threatening side effects of the medicinal product.
To determine the optimal dosing schedule for Lioresal Intrathecal 10 mg/5 ml, each patient first receives a test dose of Lioresal Intrathecal 0.05 mg/1 ml as an intrathecal bolus injection through a spinal catheter or lumbar puncture. Then, the dose is carefully adjusted individually to the patient's needs. This is necessary due to significant differences in therapeutically effective doses for individual patients.
In long-term therapy, Lioresal Intrathecal 10 mg/5 ml is administered using an implanted pump, which allows for continuous infusion of the baclofen solution into the cerebrospinal fluid.
The antispastic effect of baclofen begins within 6 to 8 hours after the start of continuous infusion, and the maximum effect is observed after 24 to 48 hours.
The initial total daily dose of Lioresal Intrathecal 10 mg/5 ml is calculated as follows: if the effect of the test dose lasts more than 12 hours, this dose is used as the initial dose. If the effect of the test dose lasts less than 12 hours, the test dose is doubled and used as the initial dose. The dose should not be increased during the first 24 hours of therapy.
After the first day of treatment, the dose can be gradually increased to achieve the desired therapeutic effect. The daily dose should not be increased by more than 10% to 30% of the previous dose in patients with spinal cord spasticity and 5% to 15% in patients with cerebral spasticity. When using a programmable pump, it is recommended to modify the dose only once every 24 hours. When using non-programmable pumps equipped with a 76 cm catheter, delivering 1 ml of solution per day, it is recommended to assess the patient's response to the new dose after 48 hours. If a significant increase in the daily dose does not increase the clinical effect, the proper functioning of the pump and the patency of the catheter should be checked.
Essentially, the dose of Lioresal Intrathecal 10 mg/5 ml is increased to achieve a maintenance dose in the range of 300 μg to 800 μg per day in patients with spinal cord spasticity. Patients with cerebral spasticity usually require smaller doses (see below).

Long-term therapy phase

The goal of treatment is to use the smallest dose that provides good control of spasticity without unacceptable side effects. Since the therapeutic effect may decrease during treatment, and the severity of spasticity may change, it is usually necessary to adjust the dose in a hospital setting during long-term therapy.
Also, in this case, the daily dose can be increased by 10% to 30% in patients with spinal cord spasticity and 5% to 20% (upper limit) in patients with cerebral spasticity by changing the infusion rate or the concentration of baclofen in the pump reservoir. And vice versa, if side effects occur, the daily dose of Lioresal Intrathecal 10 mg/5 ml can be decreased by 10% to 20%.
The need for rapid dose increase to achieve the desired therapeutic effect suggests possible pump malfunction or catheter kinking, cracking (abrasion), or displacement.
The maintenance dose of Lioresal Intrathecal 10 mg/5 ml in long-term therapy in patients with spinal cord spasticity is usually 300 μg to 800 μg of baclofen per day. The smallest and largest registered daily doses administered to individual patients during the titration phase were 12 μg and 2003 μg (studies conducted in the United States). Experience with doses exceeding 1000 μg per day is limited. During the first few months of treatment, it is necessary to verify the dose of Lioresal Intrathecal 10 mg/5 ml and modify it, especially frequently.
In patients with cerebral spasticity, the maintenance doses used during long-term therapy with continuous infusion of Lioresal Intrathecal 10 mg/5 ml are in the range of 22 μg to 1400 μg of baclofen per day, and the average daily doses of the medicinal product are 276 μg after 1 year of observation and 307 μg after 2 years. Children under 12 years of age usually require smaller doses (range: 24 μg to 1199 μg per day; average: 274 μg per day).
If the technical parameters of the pump allow, after determining the daily dose of the medicinal product and stabilizing the antispastic effect, it is possible to try to adjust the administration of the medicinal product to the daily rhythm of spasticity. For example, if spasms occur more frequently at night, this may require a 20% increase in the infusion rate for one hour. Changes in the infusion rate should be programmed to occur 2 hours before the desired clinical effect.
Throughout the treatment period, regular, at least monthly, monitoring of the patient's tolerance to Lioresal Intrathecal 10 mg/5 ml and possible signs of infection is necessary in the treatment center. The proper functioning of the infusion system should be regularly checked.
The development of local infection or catheter malfunction can lead to interruption of intrathecal administration of Lioresal Intrathecal 10 mg/5 ml with life-threatening consequences for the patient.
The concentration of baclofen required during pump filling depends on the total daily dose of the medicinal product and the infusion rate of the pump. If it is necessary to administer baclofen in concentrations other than 0.05 mg/ml, 0.5 mg/ml, or 2 mg/ml, Lioresal Intrathecal 10 mg/5 ml should be diluted under aseptic conditions using a sterile, preservative-free sodium chloride solution for injection. In this case, follow the instructions provided by the pump manufacturer.
About 5% of patients may require a higher dose of the medicinal product due to decreased treatment efficacy ("development of tolerance") during long-term treatment. As described in the literature, the development of tolerance is prevented by maintaining a 10- to 14-day break in baclofen administration, during which morphine sulfate without preservatives is administered. After this period, the patient may respond to treatment with Lioresal Intrathecal 10 mg/5 ml again. Treatment should be restarted with the initial dose used in continuous infusion, and then the dose should be gradually increased again to avoid side effects due to overdose. This procedure should be performed in a hospital setting.

Incompatibilities

Lioresal Intrathecal 10 mg/5 ml solution for infusion should not be mixed with other solutions for injection or infusion, except for sterile, preservative-free sodium chloride solution, diluted under aseptic conditions.
A chemical incompatibility has been demonstrated between dextrose and baclofen.
Do not freeze. Do not sterilize with high temperature.
