Mechanism of action
The drug has a sufficient range of antifungal action, it is used to apply directly to the infection site. Bifonazole by chemical structure belongs to the group of imidazole derivatives. It shows a fungicidal effect on the 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 deleterious effect on some bacteria - the Gram-positive rod Corynebacterium minutissimum (MIC ranging from 0.5 to 2 μg / ml) and Gram-positive cocci (MIC 4-16 μg / ml), does not affect the activity of Enterococcus spp.
Bifonazole inhibits the synthesis of ergosterol - one of the main substances that make up the shell of the fungal organism. Influence occurs at two stages of accumulation of a given substance, so there is complete damage to the fungal membrane 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 in the blood bifonazole is not detected.
Only 6 hours after the application of the drug, the concentration necessary for therapy is observed at the site of application. 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 fungicidal action for the most common pathogens that can cause dermatomycosis.
The drug continues its action in the skin for 36-48 hours. The half-life is 19-32 hours and depends 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 was affected by dermatomycosis once a day, preferably overnight. When applying, spray the spray in an amount that can moisturise the skin well. In addition to the affected areas, the intact skin should be treated, that is, the skin around 1-2 cm from the edges of the hearth.
The course of treatment depends on the type of dermatomycosis and its localization. The main principle ensuring proper effectiveness is the continuity of treatment and the maintenance of the full course. With a fungal infection of the feet and interdigital zones, the drug should be used 21-28 days, with infection of the smooth skin -14-21 days, diseases caused by Candida albicans - 14-28 days, lichen pendulous and erythematism must be treated for at least 14 days, lesion of the scalp Requires treatment for about 28-30 days. The latter diseases, in view of the specificity of the surface, require the preferred use of Bifosin spray, which is easy to apply and does not lead to 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 clinical manifestations of the disease for another 14 days, maintaining the dosage - 1 time per day.
