2. What does Tfatrax do?
Pharmacodynamics:
Itraconazole is classified as a systemic antifungal drug. Itraconazole has better antifungal activity than Ketoconazole against some fungi such as Aspergillus. It is also active against Cryprococcus, Coccidioides, Histoplasma, Blastomyces, Sporotrichosis, Candida. Itraconazole inhibits fungal cell survival and growth. In vitro studies have shown that some clinically isolated fungi (including Candida) that are less susceptible to one Azol antifungal agent are similarly susceptible to other Azol derivatives. The susceptibility of fungi to Itraconazole depends on the inoculum size, incubation temperature, culture medium, and growth stage of the fungus. Pharmacokinetics:
Absorption: When taken with or after meals, Itraconazole is better absorbed because food increases absorption. The solubility of Itraconazole is higher in acidic media. The absolute bioavailability of Itraconazole is approximately 55%, which is maximal when taken after a nutritious meal. Distribution: Itraconazole is highly bound to plasma proteins, the binding rate is 99% - 99.8%, mainly to albumin. Itraconazole is well soluble in fat, with higher concentrations in body tissues than in serum. Concentrations in lungs, stomach, liver, bones, spleen, muscles... are 2-3 times higher than in plasma. Metabolism: The liver is the site of metabolism of Itraconazole. Here, Itraconazole is metabolized into many different substances, which are then eliminated in the feces and urine. Elimination: Itraconazole is eliminated as an inactive metabolite in the urine (35%) and feces (54%). The parent drug is excreted by the kidneys less than 0.03% of the dose, while that in the faeces is 3 - 18%. Itraconazole is well absorbed by the horny tissues, especially the skin, 4 times higher than in plasma and the elimination of Itraconazole is related to skin regeneration. Plasma concentrations are undetectable 7 days after discontinuation of the drug, but can be detected in the skin after 2-4 weeks of 4-week treatment with Itraconazole. Itraconazole was detected in the skin after 1 week of treatment and was maintained for at least 6 months thereafter during a 3-month course of treatment.
