Levodopa + Carbidopa
1 What is Nakom and what is it used for
Nakom is used to treat the symptoms of Parkinson's disease and parkinsonian syndrome. Parkinson's disease is a chronic condition characterized by slow and uncoordinated movements, muscle stiffness, and tremors. Untreated Parkinson's disease can cause difficulties in performing daily activities.
The symptoms of Parkinson's disease are caused by a lack of dopamine (a chemical substance naturally found in the body), which is produced by certain brain cells. Dopamine is a neurotransmitter in the areas of the brain responsible for controlling muscle movements.
Difficulty in moving is a result of too little dopamine production.
Nakom tablets contain a combination of two active substances: levodopa (a precursor to dopamine) and carbidopa (an inhibitor of aromatic amino acid decarboxylase).
Levodopa compensates for the lack of dopamine, and carbidopa ensures that the right amount of levodopa reaches the brain. In many patients, this reduces the severity of Parkinson's disease symptoms.
Nakom should not be taken if:
Concomitant use of Nakom and non-selective monoamine oxidase inhibitors (MAO) and selective type A inhibitors is contraindicated. These medicines should be discontinued at least 2 weeks before starting Nakom.
Nakom can be used concomitantly with selective MAO type B inhibitors (e.g., selegiline hydrochloride) at the recommended dose, see "Nakom and other medicines".
Before starting to take Nakom, the patient should discuss it with their doctor or pharmacist if:
Sudden reduction or discontinuation of Nakom (especially if the patient is also taking antipsychotic medicines) may cause changes in consciousness.
Sudden reduction or discontinuation of Nakom may cause the occurrence of symptoms similar to malignant neuroleptic syndrome. This syndrome is characterized by muscle stiffness, increased body temperature, mental changes, and increased activity of creatine kinase enzyme in serum.
Due to the risk of developing melanoma (malignant skin or mucous membrane tumor), the patient's skin should be regularly checked for changes that may indicate the development of melanoma. The best solution is to have the skin checked periodically by a qualified person (e.g., a dermatologist).
The patient should consult their doctor if they or their relatives/caregivers notice unusual behaviors resulting from irresistible impulses, compulsions, or repetitive behaviors that are harmful to the patient or others. Such behaviors are called impulse control disorders and may include gambling addiction, overeating, or compulsive shopping, as well as excessive sexual drive or intense sexual thoughts and feelings. In such cases, the patient should inform their doctor, as it may be necessary to re-evaluate the treatment.
The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
In case of doubt as to whether the patient is taking any of the above medicines, they should consult their doctor or pharmacist.
The effect of levodopa in patients taking a high-protein diet may sometimes be weaker.
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor before taking this medicine.
Pregnancy
The doctor will decide whether to continue or discontinue treatment, considering the benefits of taking the medicine for the mother's health versus the risks associated with taking the medicine for the child.
Every female patient of childbearing age taking Nakom should use effective contraception. It is not recommended to take Nakom during pregnancy.
Breastfeeding
If the patient is breastfeeding, the doctor will decide whether they should continue taking Nakom, considering the importance of treatment for their health.
Levodopa may cause severe drowsiness and sudden sleep attacks, as well as double vision, which is associated with a risk of serious injury or death during activities that require full concentration. While taking Nakom, the patient should avoid driving and operating machines until the above side effects have subsided.
This medicine contains less than 1 mmol (23 mg) of sodium per tablet, which means that the medicine is considered "sodium-free".
This medicine should always be taken according to the doctor's instructions. In case of doubt, the patient should consult their doctor or pharmacist.
The doctor has prescribed the appropriate dose of Nakom, which should be taken. Usually, the following doses are used:
Patients not previously treated with levodopa
½ tablet of Nakom once or twice a day.
The doctor may increase this dose daily or every other day by ½ tablet, depending on the individual needs of the patient.
Switching from a previously used levodopa preparation to Nakom
If the patient is currently taking levodopa alone, the doctor will recommend discontinuing it at least 12 hours before starting Nakom (24 hours in the case of prolonged-release levodopa).
The switch should be made gradually and only under the doctor's supervision.
If the patient has been taking less than 1500 mg of levodopa per day
Treatment should be started with Nakom mite (100 mg + 25 mg).
Initial dose: 1 tablet three or four times a day, depending on the individual needs of the patient.
If the patient has been taking more than 1500 mg of levodopa per day
1 tablet of Nakom (250 mg + 25 mg) three or four times a day, depending on the individual needs of the patient.
The doctor will determine the individual dosage for each patient and adjust it according to the desired response to treatment.
8 tablets of Nakom per day (2 g of levodopa and 200 mg of carbidopa), which is approximately 30 mg/kg of levodopa and 3 mg/kg of carbidopa for a patient weighing 70 kg.
After several months or years of treatment, a slowing of movement (so-called "on-off" periods) has been observed, probably related to the progression of the disease.
The doctor may adjust the dose of Nakom and the intervals between doses.
In patients with kidney or liver function disorders, a change in dosage is not necessary.
In case of taking too many tablets, the patient should immediately contact their doctor or the nearest hospital.
In some patients, an early sign of taking too high a dose may be eyelid twitching.
In the event of significant overdose of Nakom, the procedure is essentially the same as in the case of levodopa overdose, except that pyridoxine does not reverse the effects of Nakom.
The patient's heart rate should be monitored using an electrocardiogram and carefully observed to detect any arrhythmias. If necessary, appropriate anti-arrhythmic treatment should be initiated. It should be taken into account that the patient may also be taking other medicines with Nakom. The importance of dialysis in the treatment of overdose is unknown.
Nakom should be taken exactly as prescribed by the doctor. If the patient forgets to take a dose, they should take it as soon as possible. If it is almost time for the next dose, the patient should not take the missed dose, but continue treatment as prescribed. The patient should not take a double dose to make up for the missed dose.
The patient should not stop taking Nakom or reduce the dose without consulting their doctor. After sudden discontinuation of Nakom, the following symptoms may occur: muscle stiffness, fever, personality changes.
