Pharmacological properties
Pharmacodynamics
Neurobion contains a complex of B vitamins, which are neurotropic active substances. These vitamins (pyridoxine, thiamine, and cyanocobalamin) play an important role in intermediate metabolism in the peripheral and central nervous system. They act as coenzymes.
The combined use of vitamins B 1, B 6 and B 12 is due to the fact that in the complex their action is more effective than for each component separately. The combination of B vitamins accelerates the regeneration processes in damaged nerve fibers.
Like other vitamins, pyridoxine, thiamine, and cyanocobalamin are essential nutrients that cannot be synthesized in the body on their own. With the therapeutic administration of B vitamins, the deficiency of vitamins from food is replenished.
The use of Neurobion in diseases of the nervous system, on the one hand, compensates for the existing deficit, which often arises due to the increased needs of the body due to the disease, and on the other hand, it stimulates natural mechanisms that are aimed at restoring the function of nerve tissues. The indirect analgesic effect of the drug has a beneficial effect on the therapeutic result.
Pharmacokinetics
After taking Neurobion inside, thiamine undergoes dose-dependent transport in the body. Its mechanism has a dual nature: at a substance concentration of up to 2 μmol / L, active absorption occurs, at concentrations above 2 μmol / L, passive diffusion is observed. Thiamine metabolism occurs in the liver by phosphorylation. The half-life is 4 hours. The tissues of the body contain about 30 mg of thiamine, with a rapid metabolism, it is excreted after 4-10 days.
The absorption of pyridoxine is very rapid and occurs mainly in the upper intestine. The half-life is 2-5 hours. To act as a coenzyme, pyridoxine is phosphorylated to pyridoxal phosphate. In phosphorylated form, it binds almost 80% to plasma proteins. In the body, the content of pyridoxine is 40-150 mg. It is excreted in the urine. From 1.7 to 3.6 mg of pyridoxine is excreted per day.
The absorption of cyanocobalamin from the digestive tract is carried out by two mechanisms: the first is the release under the influence of gastric juice and further rapid binding with an internal factor; the second is passive diffusion in the intestine, independent of the intrinsic factor. The second mechanism is more often observed at doses of cyanocobalamin more than 0.0015 mg. In patients with megaloblastic anemia (B 12 -deficient), the reabsorption of cyanocobalamin after oral administration is about 1% of a dose of 0.1 mg or more. An excess amount of cyanocobalamin accumulates in the liver, from where it is excreted with bile into the intestine, and then is reabsorbed during further intestinal-hepatic circulation. Its metabolic rate is 0.0025 mg per day.
Indications for use
Complex therapy of diseases of the nervous system:
- Paresis of the facial nerve;
- Trigeminal neuralgia;
- Sciatica, lumbago;
- Herpes zoster;
- Pain syndrome caused by diseases of the spine, such as cervical syndrome, lumbar syndrome, intercostal neuralgia, shoulder-hand syndrome, and radicular syndrome caused by degenerative changes in the spine.
Contraindications
The main contraindication to the use of Neurobion is hypersensitivity to its components.
The drug is not used in pediatrics.
In the form of tablets, the drug is contraindicated in case of hereditary intolerance to galactose or fructose, lactase deficiency, sucrose-isomaltase deficiency, glucose-galactose malabsorption (because the composition includes sucrose and lactose).
Due to the high content of vitamins, Neurobion is not recommended for use during pregnancy and lactation.
Instructions for the use of Neurobion: method and dosage
Injection
The solution is injected deep into the gluteus muscle.
With severe pain syndrome, treatment begins with a dose of 3 ml (1 ampoule) once a day. After the removal of acute symptoms, as well as in the case of moderate pain syndrome, the drug is administered 3 ml 2-3 times a week for a course of 2-3 weeks.
For prophylaxis, maintenance therapy and, if necessary, to continue the ongoing therapeutic course, the drug is prescribed in the form of tablets.
Film-coated tablets
The tablets are taken orally, swallowed whole and washed down with water, with or after meals. Usually, 1 tablet is prescribed 3 times a day, the duration of treatment is 1-1.5 months. In the case of therapy for more than 4 weeks, dose adjustment is recommended.
Side effects
In tablets Neurobion is generally well tolerated, in rare cases, side effects are noted:
- Immune system: hypersensitivity reactions (excessive sweating, tachycardia);
- Digestive system: diarrhea, nausea, abdominal pain, vomiting;
- Allergic reactions: urticaria and itching.
Possible side effects with parenteral administration of the drug:
- Due to vitamin B1: very rarely - sweating, allergic reactions in the form of rash and itching, tachycardia, hypersensitivity reactions (shortness of breath, exanthema, anaphylactic shock);
- Due to vitamin B12: in some cases - urticaria, eczema, acne.
Overdose
B vitamins have a wide range of effective concentrations. When using Neurobion in compliance with the recommended dosage regimens, overdose symptoms are not observed.
Vitamin B 1 in high doses exceeding the recommended 100 times or more (over 10 g) exhibits a curariform ganglion blocking effect, suppressing the transmission of impulses in nerve cells (muscle relaxant effect).
Peripheral sensory neuropathy may occur after taking vitamin B 6 in a daily dose of more than 50 mg for 6–12 months. Prolonged intake (more than 2 months) of pyridoxine in doses exceeding 1 g per day can cause neurotoxic effects. Daily doses of more than 2 g led to the appearance of neuropathy with ataxia, cerebral convulsions with changes in the electroencephalogram, sensory disorders, hypochromic anemia and seborrheic dermatitis.
After parenteral administration of high doses of cyanocobalamin and in rare cases after its ingestion, symptoms of overdose such as benign acne and eczematous skin disorders were observed.
Treatment consists in discontinuation of the drug, gastric lavage and intake of activated charcoal. If necessary, symptomatic, including desensitizing, therapy is carried out.
special instructions
Neurobion solution is not allowed to be administered intravenously.
Vitamin B12 can affect the clinical picture and laboratory tests in pernicious anemia and funicular myelosis.
Vitamin B1 can inactivate other vitamins, especially cyanocobalamin.
If long-term treatment is necessary, the patient's condition should be monitored regularly, because long-term use (more than 6 months) of vitamin B6 in a daily dose of 50 mg can lead to the development of peripheral sensory neuropathy.
Neurobion does not have a negative effect on the speed of reactions and the ability to concentrate.
Application during pregnancy and lactation
Neurobion is not recommended for use during pregnancy and breastfeeding due to its high vitamin content.
B vitamins are secreted in breast milk, but the risk of overdose in infants has not been established. In some cases, taking high doses of pyridoxine (more than 600 mg per day) can lead to suppression of lactation.
If the use of the drug during lactation is necessary according to indications, breastfeeding should be discontinued.
Pediatric use
According to the instructions, Neurobion is contraindicated in children and adolescents under the age of 18 (due to the high content of active ingredients).
Drug interactions
- Antacids: decreased absorption of thiamine;
- Fluorouracil: inactivation of thiamine;
- Levodopa: a decrease in its antiparkinsonian action;
- "Loop" diuretics (for example, furosemide): increased excretion of thiamine with prolonged use and, as a result, a decrease in its concentration in the blood;
- Pyridoxine antagonists (eg, penicillamine, hydralazine, cycloserine, isoniazid): increased need for pyridoxine;
- Ethanol and black tea: decreased absorption of thiamine;
- Sulphite-containing drinks (including wine): enhances the breakdown of thiamine.
In the form of a solution, Neurobion cannot be mixed with other drugs in the same syringe.
