Pharmacodynamics

The active ingredient of Lycopid is glucosaminyl muramyl dipeptide. It is a synthetic analog of the structural fragment of the shell (peptidoglycan) of bacterial cells. GMDP is an activator of congenital and acquired immunity; it enhances the body’s defense against viral, bacterial and fungal infections and has an adjuvant effect in the development of immunological reactions. The biological activity of the drug is realized through the binding of GMDP to intracellular receptor protein NOD2 localized in the cytoplasm of phagocytes (neutrophils, macrophages, dendritic cells). The drug stimulates the functional (bactericidal, cytotoxic) activity of phagocytes, enhances their presentation of antigens, the proliferation of T- and B-lymphocytes; it increases the synthesis of specific antibodies and contributes to the normalization of the balance of Th1/Th2 lymphocytes towards the prevalence of Th1. Pharmacological action lies in enhancing the production of key interleukins (interleukin-1, interleukin-6, interleukin-12), necrosis factor of alpha tumors, gamma interferon, and colony-stimulating factors. The drug increases the activity of natural killer cells.

Licopid has low toxicity (LD50 for 1 mg tablets exceeds the therapeutic dose more than 106,000 times, and for 10 mg tablets more than 49,000 times). In experiments with the per os administration in doses 100 times exceeding the therapeutic one, the drug has no toxic effect on the central nervous and cardiovascular systems and it does not cause pathological changes in internal organs. Lycopid does not exercise embryotoxic and teratogenic effects and does not cause chromosomal gene mutations. In experimental studies conducted on animals, Lycopid demonstrated anticancer activity.

Pharmacokinetics

The oral bioavailability of the drug is 7–13%. The degree of binding to blood albumins is weak. The time to reach the maximum concentration (tmax) is 1.5 hours after administration. The half-life (t1/2) is 4.29 hours. The drug does not form metabolites; it is excreted in the unchanged form mainly through the kidneys.

Precaution

Every 1 mg tablet of Licopid contains sucrose in the amount of 0.00042 c.u. (carbohydrate units); every 10 mg tablet of Licopid contains sucrose in the amount of 0.001 c.u., which should be taken into account by patients with diabetes mellitus.

Every 1 mg tablet of Licopid contains 0.074 grams of lactose; every 10 mg tablet of Licopid contains 0.184 grams of lactose, which should be noted by patients suffering from hypolactasia (lactose intolerance, in which the body has a decrease in the level of lactase – an enzyme necessary for digesting lactose).

Elderly patients should take Licopid 10 mg with caution and under the strict supervision of the doctor.

In the beginning of the course of Licopid 10 mg, exacerbation of symptoms of chronic and latent diseases is possible, which is associated with the main pharmacological effects of the drug.

The decision to prescribe Licopid 10 mg to patients with a combination of psoriasis and gout should be made by the doctor, assessing the risk/benefit ratio, as there is a potential risk of exacerbation of gouty arthritis and joint swelling. If the decision is made to prescribe Licopid 10 mg to a patient with a combination of psoriasis and gout, the treatment should be started with low doses. If side effects do not occur, the dose can be increased up to a therapeutic one.

Side effects

Often (1–10%): At the beginning of the treatment with Licopid 1 mg, a short-term increase in the body temperature to subfebrile values (up to 37.9°C or 100.22°F) may be recorded, which is not an indication for the drug withdrawal. When taking Licopid 10 mg, arthralgia (joint pain) and myalgia (muscle pain) may be manifested; at the beginning of the treatment, a short-term increase in the body temperature to subfebrile values (up to 37.9°C or 100.22°F) may be recorded, which is not an indication for the drug withdrawal. Most often, the side effects described above are observed when taking Licopid® tablets in high doses (20 mg).

Rarely (0.01–0.1%): A short-term increase in the body temperature to febrile values (>38.0°C or >100.4°F). If the body temperature rises above 38.0°C (100.4°F), antipyretic drugs may be administered. They do not reduce pharmacological effects of Licopid tablets.

Very rarely (<0.01%): Diarrhea.

If any of the side effects listed in the description aggravate, or if you notice any other side effects not listed in the description, notify your doctor.

Overdose

Cases of overdose have not been reported.

Based on the pharmacological properties of the drug, in case of an overdose, the body temperature can rise up to subfebrile values (37.9°C or 100.22°F). If necessary, symptomatic therapy can be conducted, including antipyretic drugs and sorbent prescription. There is no specific antidote.

Interaction with other drugs

The drug increases the effectiveness of antimicrobials, there is a synergy regarding antiviral and antifungal drugs. Antacids and sorbents significantly reduce the bioavailability of the drug. Glucocorticosteroids reduce the biological effect of Lycopid.
