Description of dosage form:

The prepared solution is a colorless transparent liquid.

Characteristic:

Erythromycin-zinc complex.

Pharmacological action:

Erythromycin blocks the synthesis of microbial cell protein, causing bacteriostatic effect. Zinc stabilizes cell membranes, has astringent, anti-inflammatory and antiseptic effect, reduces the production of sebum secretion.

Pharmacokinetics:

The complex bond of the preparation components ensures good penetration of active substances into the skin. Zinc is mainly associated with the follicular epithelium and is not resorbed into the systemic bloodstream. A small part of erythromycin undergoes systemic distribution and is subsequently excreted from the body.

Description of the pharmacological action:

Erythromycin acts bacteriostatically on microorganisms that cause acne: Propionibacterium acne and Streptococcus epidermidis. Zinc reduces the production of sebum secretion, has a binding effect.

Indications:

Acne (treatment).
