Itraconazole

Itraconazole  belongs to the triazole class of antifungal drugs. It works by slowing the infection-causing fungi's growth.

Itraconazole is indicated for the treatment of the following fungal infections when thought likely to be susceptible:

  • Vulvovaginal candidiasis
  • Pityriasis versicolor
  • Dermatophytoses caused by organisms susceptible to itraconazole (Trichophyton spp. Microsporum spp. Epidermophyton floccosum) e.g. tinea pedis, tinea cruris, tinea corporis, tinea manuum.
  • Oral and systemic candidiasis.
  • Onychomycosis caused by dermatophytes and/or yeasts.

 

Indication

Dose

Vulvovaginal candidiasis

200 mg twice daily for 1 day

Pityriasis versicolor

200 mg once daily for 7 days

Tinea corporis, tinea cruris

100 mg once daily for 15 days

Tinea pedis, tinea manuum

100 mg once daily for 30 days

Itraconazole can cause the following side effects-

  • Abdominal pain
  • nausea
  • Rash
  • Headache
  • dizziness
  • diarrhoea
  • dyspepsia
  • Taste disturbances
  • Edema
  • Liver problems (rare)
  • Thrombocytopenia
  • A transient asymptomatic decrease in left ventricular ejection fraction was seen in a healthy volunteer study with intravenous itraconazole; this reversed before the following infusion.
  • If the benefit clearly outweighs the danger, itraconazole should be given in individuals with congestive heart failure or a history of congestive heart failure.
  • In patients with a history of hepatic dysfunction, the value of hepatic enzymes should be evaluated. It should also be done on a regular basis in all patients who have been on continuous treatment for more than one month, or whenever a patient exhibits signs and symptoms of liver dysfunction.

Contraindication

Contraindicated in patients hypersensitive to Itraconazole or other azole antifungal medications, such as-

Concomitant administration with Rifampicin is contraindicated.
