Glucocorticosteroid for topical use.

Pharmacological properties

The active ingredient of Advantan, methylprednisolone aceponate, is a non-halogenated steroid.

Pharmacodynamics

When applied externally, Advantan suppresses inflammatory and allergic skin reactions, as well as those associated with enhanced proliferation, which leads to a decrease in the objective symptoms of inflammation (erythema, edema, oozing, etc.) and subjective sensations (itching, irritation, pain and etc.).

When methylprednisolone aceponate is used externally at the recommended dose, the systemic effect is minimal in both humans and animals.After repeated application of Advantan on large surfaces (40-60% of the skin surface), as well as when applied under the occlusive dressing, there are no violations of the adrenal glands: plasma cortisol level and its circadian rhythm remain within the normal range, there is no decrease in cortisol level in daily urine.

In clinical studies with Advantan up to 12 weeks in adults and up to 4 weeks in children (including young children), no development of skin atrophy, telangiectasias, striae and acne-like rashes were detected.

Methylprednisolone aceponate (especially its main metabolite, 6α-methylprednisolone-17-propionate) binds to intracellular glucocorticosteroid receptors. The steroid-receptor complex binds to specific parts of the DNA of the cells of the immune response, thus causing a series of biological effects.

In particular, the binding of the steroid-receptor complex with DNA cells of the immune response leads to the induction of macrocortin synthesis. Macrocortin inhibits the release of arachidonic acid and, thereby, the formation of inflammatory mediators such as prostaglandins and leukotrienes.

Inhibition of the synthesis of vasodilating prostaglandins by glucocorticosteroids and the potentiation of the vasoconstrictive action of adrenaline lead to a vasoconstrictor effect.

Pharmacokinetics

Methylprednisolone aceponate is hydrolyzed in the epidermis and dermis.The main and most active metabolite is 6α-methylprednisolone-17-propionate, which has a significantly higher affinity for the glucocorticosteroid receptors of the skin, which indicates the presence of its “bioactivation” in the skin.

The intensity of absorption through the skin with artificial inflammation is very low (0.27% of the dose), which is only slightly higher than through healthy skin (0.17%). In the case of treatment of the whole body (for example, with sunburn), the systemic dose is about 4 μg per kg of body weight per day, which excludes systemic effects.

After entering the systemic circulation, 6α-methylprednisolone-17-propionate is rapidly conjugated with glucuronic acid and, thus, in the form of 6α-methylprednisolone-17-propionate, glucuronide is inactivated.

Metabolites of methylprednisolone aceponate are eliminated mainly by the kidneys with a half-life of about 16 hours. Methylprednisolone aceponate and its metabolites do not accumulate in the body.

Indications for use

Inflammatory skin diseases sensitive to therapy with topical glucocorticosteroids:

• atopic dermatitis, neurodermatitis, children eczema;
• simple contact dermatitis;
• allergic (contact) dermatitis;
• true eczema;
• seborrheic dermatitis / eczema
• microbial eczema;
• photodermatitis, sunburn.

Contraindications

• tuberculous or syphilitic processes in the field of drug application;
• viral diseases (for example, chicken pox, shingles) in the area of ​​application of the drug;
• rosacea, perioral dermatitis in the area of ​​application of the drug;
• children's age up to 4 months;
• skin areas with reactions to vaccination;
• hypersensitivity to the drug.

Pregnancy and lactation

If necessary, the use of Advantan emulsion during pregnancy and lactation should carefully weigh the potential risk to the fetus and the expected benefit of treatment for the mother. During these periods, prolonged use of the drug on large skin surfaces is not recommended.

Nursing mothers should not put the drug on the mammary glands.

Dosage and administration

Outwardly. Adults and children from 4 months of age. The drug is applied 1 time per day (for the treatment of sunburn 1-2 times a day) in a thin layer on the affected skin, rubbing slightly.

Usually the treatment should not exceed 2 weeks.

If the skin dries excessively when using Advantan emulsion, it is necessary to switch to a higher-fat dosage form (Advantan ointment or Advantan oily ointment).

Side effect

Usually the drug is well tolerated.

Very rarely (less than in 0.01% of cases) local reactions can be observed, such as itching, burning, erythema, and the formation of vesicular rash. If the drug is used for more than 4 weeks and / or over an area of ​​10% or more of the body surface, the following reactions may occur: skin atrophy, telangiectasia, stretch marks, acneform skin changes, systemic effects due to corticosteroid absorption.In clinical studies, none of the above side effects were noted when using Advantan emulsion for up to 12 weeks in adults and up to 4 weeks in children.

In rare cases (0.01% - 0.1%), folliculitis, hypertrichosis, perioral dermatitis, depigmentation of the skin, allergic reactions to one of the components of the drug can be observed.

Overdose

When studying the acute toxicity of methylprednisolone aceponate, there was no risk of acute intoxication in case of excessive single skin application (application of the drug over a large area under conditions favorable for absorption) or unintentional ingestion.

With excessively long and / or intensive use of glucocorticosteroids, skin atrophy may develop (thinning of the skin, telangiectasia, striae).

With the appearance of atrophy, the drug must be canceled.

Interaction with other drugs

Not found.

special instructions

In the presence of bacterial complications and / or dermatomycosis, in addition to treatment with Advantan, specific antibacterial and / or antimycotic treatment is necessary.

Avoid contact with eyes.

As with the use of systemic glucocorticosteroids, glaucoma may develop after external use of glucocorticosteroids (for example, when using large doses, or very long use of occlusive dressings or application to the skin around the eyes).

Influence on ability to steer vehicles, mechanisms

Not found.
