Mechanism of action
The drug has a sufficient spectrum of antifungal action, is used to apply directly to the site of infection. Chemical structure of bifonazole belongs to the group of imidazole derivatives. It shows a fungicidal effect on a group of dermatophytes (Trichophyton, Microsporum, Epidermophyton), stops the growth and reproduction of yeast-like and mold fungi (Aspergillus ferrus, Scopulariopsis brevicaulis), Malassezia furfur. In addition, it has a detrimental effect on some bacteria - on the gram-positive bacillus Corynebacterium minutissimum (BMD ranges from 0.5 to 2 μg / ml) and on gram-positive cocci (BMD 4-16 μg / ml), does not affect the vital activity of Enterococcus spp.
Bifonazole inhibits the synthesis of ergosterol - one of the main substances that make up the shell of the fungal organism. The effect occurs at two stages of accumulation of a given substance, therefore there is a complete damage to the shell of the fungus with a violation of both structure and function. This leads to its death (fungicidal action) or to the cessation of reproduction and growth (fungistatic action).
The drug quickly penetrates deep into the skin in the foci of the disease. Absorption is 0.6-0.8%, while bifonazole is not detected in the blood.
Within 6 hours after the application of the medicine, the concentration required for therapy is observed at the site of use. It is 1 mg / cm 2 in the uppermost layer of the skin - the epidermis and 5 mg / cm 2 in the lower layers. This concentration guarantees a fungicidal action for the most common pathogens that can cause ringworm.
The drug continues its action in the skin for 36-48 hours. The half-life is 19-32 hours and is directly dependent on the density of the skin in the lesion.
How to apply and in what doses?
Bifosin spray is applied to the surface of the skin, which has been affected by ringworm once a day, preferably overnight. When applying should spray spray in an amount that can well moisturize the skin. In addition to the affected areas, intact skin should also be treated, that is, the skin around about 1-2 cm from the edges of the focus.
The course of treatment depends on the type of ringworm and its localization. The basic principle that ensures proper effectiveness is the continuity of treatment and maintaining the full course. For fungal infections of the feet and interdigital areas, the drug should be used for 21-28 days, for infection of smooth skin is 14-21 days, diseases caused by Candida albicans are 14-28 days, pityriasis and erythasis should be treated for at least 14 days, damage to the scalp treatment requires about 28-30 days. Recent diseases, in view of the specificity of the surface, require the preferred use of Bifosin spray, which is easy to apply and does not cause sticking and contamination of the hair.
In order to prevent the possibility of recurrence of the disease should continue the course of therapy and after the elimination of the clinical manifestations of the disease for another 14 days, the maintenance dosage should be 1 time per day.
Due to the low adsorption of the drug in the general bloodstream, it is almost impossible to overdose Befosin.
