- 3.2 Usage
- The imidazole antifungal agents for the triazole ring, through inhibiting the activation of cytochrome P-450, including oxidase and peroxidase, disable the 14, α-methyl sterols to be dehydrogenated and be converted to ergosterol, so that the growth and proliferation of fungi are inhibited. They have strong lipophilicity and penetrate through the biofilm to inhibit the binding of the membrane to the fungus. The antibacterial spectrum is similar to ketoconazole. It is effective in the treatment of superficial fungal diseases such as vaginal and oral candidiasis as well as skin mycosis. Furthermore, it is expected to become the highly-efficient and safe drugs for the treatment of deep fungal infections such as cryptococcal encephalitis (AIDS). It is used for the treatment of vulvovaginal candidiasis, pityriasis and skin fungal disease pityriasis caused by sensitive fungi.It can be used for the synthesis of broad-spectrum azole antifungal agents for the treatment of systemic infection caused by deep fungus. It can also be used for the treatment of candidiasis and aspergillosis.

- 8.2 Broad - spectrum antifungal agents
- Itraconazole is an artificially synthetic clotrimazole, being a broad-spectrum synthetic antifungal agent. Its antimicrobial spectrum and antimicrobial mechanism is similar to clotrimazole, but has strong antibacterial activity against Aspergillus. It exerts its anti-fungal effect through changing the fungal cell membrane permeability with antibacterial activity against superficial and deep fungal pathogens. Its antibacterial spectrum is broader and stronger than ketoconazole, being able to inhibit the ergosterol synthesis of fungal cell membrane, thus playing the antifungal effect. This product is suitable for the treatment of Dermatophytes (Trichophyton, Microsporum, Flocculent Epidermophyton), Yeast [Cryptococcus neoformans, Pityrosporum, Candida (including Candida albicans, Candida glabrata and candida krusei)], Aspergillus, Histoplasma, Paracoccidioides brasiliensis, Sporothrix schenckii, Hormodendrum, Cladosporium, Blastomyces dermatitidis and various kinds of other types of yeasts and fungi. Itraconazole is not able to inhibit the growth of Rhizopus and Mucor.
One nitrogen atom contained in the itraconazole molecule can bind to the ferrous ion on the heme of the P450 molecule in the fungal cell, thereby inhibiting the P450 hydroxylase-catalyzed de-methylation of lanosterol, Sterol to ergosterol conversion blocked, lanosterol and other precursors accumulation, membrane chemical composition changes, membrane associated enzyme dysfunction, increased permeability, intracellular fluid spill, so as to achieve the inhibition and sterilization. The combination of this product with the fungus P450 system is quite strong while its combination with the mammalian P450 system is weak, so that the toxicity of drugs on human is greatly reduced. Clinical Itraconazole is mainly used for the treatment of systemic deep fungal infections caused by systems such as blastomycosis, histoplasmosis, coccidioidomycosis, chromoblastomycosis, sporotrichosis and coccidioidomycosis. It can also be used for the treatment of candidiasis and aspergillosis.

- 8.3 Pharmacokinetics
- Itraconazole, when taken immediately after the meal, can give the highest bioavailability. After (4.6 ± 1.3) hours of oral administration of 200 mg of itraconazole, the plasma concentration can reach peak with the plasma concentration being (0.32 ± 0.16) mg/mL. The product has a plasma protein binding rate of 99.8% with the whole blood concentration being about 60% of the plasma concentration. The drug concentration in the lung, kidney, liver, bone, stomach, spleen and muscle was found to be 2 to 3 times as high as that in the corresponding plasma concentration. In keratin-rich tissues, especially in the skin, the concentration is four times as high as that in the plasma concentration while the drug clearance is associated with the process of epidermal regeneration. If withdraw the drug after continuous medication of 4 weeks, the plasma concentration become undetectable after 7 days while drug contained in the skin can be still maintained in the drug treatment concentration for 2 to 4 weeks. After a week of starting the treatment, it can be measured of itraconazole in the keratin. At the end of the 3-month treatment course, the drug concentration can be maintained for at least 6 months. This product is present in sebum with a small amount also existing in sweat. Itraconazole is also concentrated in areas susceptible to fungal infection. The duration of the treatment concentration in the vaginal tissue is: 200mg once per day for 3 days, last for 2 days; 200mg 2 times a day for 1 day, can last 3 days. Itraconazole is mainly metabolized in the liver, producing large amounts of metabolites. One of them is hydroxylated itraconazole; in vitro study has found that it has a similar antifungal activity with this product. The level of antifungal drug measured by bioanalytical method is three times as high as the level measured by high-pressure liquid chromatography analysis. This product was biphasic in plasma clearance with the terminal half-life of (23.8 ± 4.7) hours. The dosage of the prototype drug through fecal excretion accounts for about 3 to 18% of the total dose. The prototype drug via renal excretion is less than 0.03% of the dose with about 35% being subject to urine excretion in the form of metabolites within a week.

- 8.4 Clinical application and indications
- Itraconazole is applicable for the treatment of the following diseases:
1, it can be used for the treatment of systemic fungal infections, such as aspergillosis, candidiasis, cryptococcosis (including cryptococcal meningitis), histoplasmosis, sporotrichosis, Paracoccidioides brasiliensis disease, blastomycosis and many other kinds of rare systemic or tropical fungal diseases.
2, it can be used for the treatment of the candidiasis infection occurred in the mouth, throat (foreign data), esophageal (foreign data) and vulvovagina, and fungal conjunctivitis, fungal keratitis.
3, it can be used for the treatment of superficial fungal infections, such as hand, foot and ringworm, tinea corporis, tinea corporis, tinea versicolor and so on.
4, it can be used for the treatment of dermatophytes and (or) yeast-induced onychomycosis.
- 8.5 Dosage and Usage
- Capsules: In order to achieve optimal absorption, itraconazole capsules should be administered immediately after a meal and the capsule must be swallowed. 1. Candida vaginitis: 200mg each time, twice a day, a course of treatment for 1 day or 200mg, once the course of treatment of 3 days; 2. Tinea versicolor: 200mg each time, once a day with the course of treatment of 7 days ; 3. Dermatomycosis: 100 mg each time, once a day with the course of treatment of 15 days; high-degree keratinized area (such as foot bottom ringworm, hand tinea) need: extended treatment of 15 days; 4 Oral candidiasis: 100mg each time, once a day with the course of treatment of 15 days; 5. Fungal keratitis: 200 mg each time, once a day with the course of treatment of 21 days; 6. For some immunodeficiency patients, such as leukemia (such as leukemia), AIDs and organ transplanted patients, application of itraconazole capsules for the treatment of fungal infections can get reduced oral bioavailability; in this case, the dose can be doubled. 7. Onychomycosis: 1) shock treatment: 200 mg each time, twice per day with continuous one week as a shock treatment. For the treatment of nail infections, it is recommended to adopt two shock treatment courses with each course having a gap of 3 weeks; for the treatment of toenail infection, it is recommended to adopt three shock treatment courses. Each treatment course has a gap of 3 weeks. 2) Or adopt continuous treatment: 200 mg each time, once a day, continue for three months. This product is removed more slowly in the skin and keratin tissue than removed in the plasma. Therefore, for skin infections, 2 to 4 weeks after stopping the drug can achieve the most ideal clinical and mycological efficacy. For the treatment of onychomycosis, people can achieve the best clinical and mycological efficacy after 6~9 months of stopping the drugs.
Injection: during the first two days, give itraconazole injection 2 times a day, later change to once per day. Treatment protocol in Day 1 and 2: 2 times per day; adopt intravenous infusion of 200 mg itraconazole 1 hour each time. From day 3: perform once per day with intravenously infusion of 200 mg of itraconazole for 1 hour each time. The safety for intravenous administration of more than 14 days is not clear. - View all

- 8.22 Indications
- Itraconazole (Sporanox) is effective in the treatment of histoplasmosis, blastomycosis, candidiasis, and dermatophyte infection. Its efficacy in the treatment of tinea capitis in children is equal to griseofulvin, and it is usually better tolerated (21). It is metabolized by the cytochrome P-450 system and may increase the levels ofwarfarin, cyclosporine, and digoxin among others. Its use is contraindicated with certain medications.
Itraconazole (Sporanox) is a triazole antifungal that is related to the imidazole ketoconazole. Similar to ketoconazole, it interferes with ergosterol synthesis and cell membrane integrity. It is clinically active against dimorphic fungi, yeast, dermatophytes, Blastomycetes, histoplasmosis, sporotrichosis, and Aspergillus. Itraconazole is a potent inhibitor of the cytochrome P450 3A enzyme system, which may elevate blood levels of other drugs metabolized by this system if taken concomitantly. Itraconazole levels may decrease in patients who are concurrently taking rifampin, phenobarbital, or phenytoin. Cyclosporine, felodipine, digoxin, warfarin, and oral hypoglycemic levels may increase when given in conjunction with itraconazole. Itraconazole, like ketoconazole, is contraindicated in patients taking cisapride. Itraconazole may induce torsades de pointes, ventricular arrhythmias, and congestive heart failure. - View all
