riba dermatophytes
(Microsporum canis, Trychophyton rubrum, Epidermophyton floccosum et al.), Molds, and dimorphic fungi (Pityrosporum orbiculare). Against yeasts Terbizil and has fungicidal and fungistatic effect. Fungicidal effect is achieved by inhibiting the sterol synthesis in the cells, resulting in inhibition of production
ergosterol
And this in turn causes the death of the microorganism. Additionally Terbizil causing inhibition of the enzyme
squalene epoxidase
. Squalene epoxidase is located in the cell membrane, and the violation of its work leads to an accumulation of squalene in the cell and the death of the fungus. For a man Terbizil quite dangerous, as in human cells such terbinafine has no effect. Terbizil produced in 2-forms for topical cream (1%, 1 g terbinafine contains 10 mg) and a tablet containing 125 or 250 mg terbinafine.

Contraindications:
Absolute contraindications for prescribing Terbizil not, the only possible - increased sensitivity to terbinafine. Relative (appoint Terbizil be careful) Contraindications: hepatic pathology system and kidneys, accompanied by organ dysfunction and failure. It is necessary to be careful in the presence of disease in the patient forming organs and endocrine diseases, cardiovascular and oncological diseases . No experimental evidence of the safety of terbinafine in pediatric practice, until the age of two drug use under strict indications. It is not necessary to appoint Terbizil breastfeeding, Bremen.
Side effect:
With a frequency of up to 10% are possible violations on the part of the digestive tract : Loss of appetite, nausea, diarrhea, pain in the epigastric region. Terbizil may cause allergic skin reactions (rash, hives). It is noted that in patients receiving the drug, pain in joints and muscles. Nervous system may react to the drug dizziness. Can a headache. It is rare, but not excluded taste disturbances, up to complete its loss, stagnation in the hepato-duodenal area pankreo-( cholestatic jaundice ), A polymorphic exudative erythema, bullous dermatitis up to toxic epidermal necrolysis ( Lyell's syndrome ) There may be signs of depression forming organs function: agranulocytosis and thrombocytopenia , Lymphopenia or neutropenia. The application site is not possible occurrence of itching and burning skin, hyperemia .
Mode of application:
The duration of therapy is largely determined by the nature of the disease and its severity. In pediatrics in the treatment of children, starting from the third year of life, the dosages of 125 mg, administered once (a day). Adults should apply the dosage of 250 mg is recommended to take the number Terbizila at once. When onychomycosis the duration of effective treatment - from six to twelve weeks, is determined by the rate of growth of healthy nail. Duration of treatment may be determined by other factors: age, presence of comorbidities. Terbizil used in the treatment Tinea pedis (plantar, interdigital or the type of socks) - the duration of treatment from two to six weeks; while other areas of the skin tinea therapy continues for two to four weeks; diseases of the head mycotic etiology - 4 weeks. Terbizil cream is applied 1-2 times a day. It should be clean and dry before applying the lesions Terbizila.

Treatment is aimed at removing the drug from the body: it is necessary to wash out the stomach and give the patient Activated carbon or other sorbents. Since Terbizil can influence the function of the liver, during the course of antifungal therapy must be controlled transaminases (hepatic enzymes) in the plasma of the patient. Avoid Terbizila eyes. If you get recommended copious rinsing with running water.
Drug Interactions:
Terbizil affect the clearance of drugs metabolized by the system takes place P450 (tolbutamide, cycloserine , Oral contraceptives), and terbinafine may either accelerate or slow the metabolism of these drugs. Metabolism of Terbizila can accelerate substances that enhance the activity of microsomal enzymes of the liver cells ( rifampicin ). Drugs that inhibit the activity of the enzyme cytochrome P450, slow excretion of terbinafine, which requires adjusting the dose of the latter.
