Effectiveness
How Itraconazole Affects Patients
Itraconazole is a medicine used to treat fungal infections. It works by blocking an enzyme (cytochrome P450 14α-demethylase) found in fungi that is needed for the fungi to grow. This medicine has been shown to be effective at stopping the growth of various types of fungi, such as Cryptococcus neoformans and Candida spp. It can also be used to treat fungal infections in both healthy and immunocompromised (low immunity) animals.
How Itraconazole works in the body
Itraconazole stops the fungus from making a compound called ergosterol, which is vital for its cell membrane. When the cell membrane is weakened, it can no longer contain the contents of the cell, which will eventually lead to the death of the fungus. Itraconazole may also stop the fungus from getting energy, stop it from changing from a yeast form to a mycelial form, and prevent it from taking in nutrients.
When to interrupt dosage
The prescribed dosage of Itraconazole is contingent upon the diagnosed condition, including Onychomycosis, prophylaxis of Penicilliosis and Coccidioidal meningitis. The amount of dosage is contingent upon the technique of delivery, as detailed in the table below.
