Pharmacological properties
Pharmacodynamics.
α-Lipoic acid plays the role of a coenzyme in the oxidative decarboxylation of α-keto acids.
Hyperglycemia caused by diabetes leads to the accumulation of glucose on the matrix proteins of blood vessels and the formation of so-called “advanced glycation end products.” This process leads to reduced endoneural blood flow and endoneural hypoxia/ischemia, which is associated with increased production of oxygen free radicals, which lead to peripheral nerve damage.
Animal studies have shown that α-lipoic acid affects the biochemical processes caused by streptozotocin-induced diabetes, leading to improved endoneural blood flow and increased levels of the physiological antioxidant glutathione, and as an antioxidant, it reduces the number of oxygen free radicals in the diabetically altered nerve.
The effects observed in the experiment indicate that peripheral nerve function can be improved with α-lipoic acid. This is relevant to the sensory disturbances in diabetic polyneuropathy, which can manifest in forms of paresthesia such as burning, pain, numbness, and "creeping sensations."
Pharmacokinetics.
After oral administration, α-lipoic acid is rapidly and almost completely absorbed from the gastrointestinal tract. Due to the significant first-pass effect, the absolute bioavailability of α-lipoic acid (defined as the parent substance) after oral administration is approximately 20% compared to that after intravenous administration. Due to rapid tissue distribution, the half-life of α-lipoic acid is approximately 25 minutes. The relative bioavailability of α-lipoic acid (compared to the oral solution) is > 60%. The maximum plasma concentration of 4 μg/ml was observed approximately 0.5 hours after oral administration of 600 mg α-lipoic acid. Experiments on animals (rats, dogs) using radioactive labels showed that the drug is excreted mainly by the kidneys by 80–90%, mainly in the form of metabolites. In humans, only a small part of the unchanged substance remains in the urine. Biotransformation occurs mainly through oxidative reduction of side chains (β-oxidation) and/or through S-methylation of the corresponding thiols.
Indication
Treatment of symptoms of peripheral (sensorimotor) diabetic polyneuropathy.
Contraindication
Hypersensitivity to thioctic acid and other components of the drug.
Interaction with other medicinal products and other types of interactions
The effectiveness of cisplatin is reduced when used simultaneously with thioctic acid.
Thioctic acid is a metal chelator, so it cannot be used together with metal compounds (iron, magnesium preparations, with dairy products, since they contain calcium). If the daily dose of the drug is taken 30 minutes before breakfast, then preparations containing iron or magnesium should be taken at lunch or in the evening. α-lipoic acid forms poorly soluble complexes with sugar molecules (for example, with a solution of lavulose).
When using the drug Dialipon® in patients with diabetes mellitus, it is possible to increase the blood sugar-lowering effect of insulin and oral antidiabetic agents, therefore, especially at the initial stage of treatment, careful monitoring of blood sugar levels is recommended. To avoid symptoms of hypoglycemia, in some cases it may be necessary to reduce the dose of insulin or oral antidiabetic agents.
WARNING
Regular alcohol consumption is a significant risk factor for the development and progression of the clinical picture of neuropathy and may therefore negatively affect the treatment process with Dialipon®. Therefore, patients with diabetic polyneuropathy are usually advised to abstain from alcohol whenever possible. Limiting alcohol consumption also applies to breaks between courses of treatment.
Application features
When using the drug, an unusual urine odor may be observed, which has no clinical significance.
At the beginning of treatment for polyneuropathy, due to regeneration processes, a short-term increase in paresthesias with a feeling of "creeping ants" is possible.
Use during pregnancy or breastfeeding
There is no data on the penetration of thioctic acid into breast milk, therefore its use during breastfeeding is not recommended.
Ability to influence reaction speed when driving vehicles or other mechanisms
During treatment, caution should be exercised (due to the possibility of side effects such as dizziness and visual disturbances) when driving vehicles and engaging in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.
Method of administration and doses
Adult patients should be prescribed 1 tablet of Dialipon® (equivalent to 600 mg of α-lipoic acid) once a day. Take approximately half an hour before the first meal.
The drug should be taken on an empty stomach, without chewing and with sufficient water. Taking the drug with food may reduce the absorption of α-lipoic acid, so it is recommended to take the entire daily dose half an hour before breakfast.
The duration of treatment is determined by the doctor individually.
Children.
Since there is no data on the safety and efficacy of this drug in children, it is not recommended to prescribe the drug to this age group of patients.
Overdose
Overdose may cause nausea, vomiting and headache. After accidental ingestion or attempted suicide with oral administration of thioctic acid in doses from 10 g to 40 g in combination with alcohol, significant intoxication was observed, in some cases with a fatal outcome. At the initial stage, the clinical picture of intoxication may manifest itself in the form of psychomotor agitation or clouding of consciousness. Later, generalized convulsions and lactic acidosis occur. In addition, hypoglycemia, shock, acute skeletal muscle necrosis, hemolysis, disseminated intravascular coagulation syndrome, bone marrow suppression and multiple organ failure have been described in intoxication with high doses of thioctic acid.
Treatment. If severe intoxication is suspected, immediate hospitalization is recommended and measures are taken in accordance with the general principles of accidental poisoning (e.g., induce vomiting, gastric lavage, use activated charcoal). Treatment of generalized convulsions, lactic acidosis and other life-threatening consequences of intoxication should be carried out in accordance with the principles of modern intensive care; such treatment should be symptomatic. The benefit of hemodialysis, hemoperfusion or the use of filtration methods with forced removal of thioctic acid has not yet been confirmed.
Side effects
On the part of the digestive tract: often - nausea; in rare cases - gastrointestinal disorders, including vomiting, abdominal pain and gastrointestinal pain, diarrhea.

Others: difficulty breathing.
