Study of Itraconazole in Patients With Advanced HIV Infection

Official Title: “Pharmacokinetics Study of Intravenous Itraconazole Followed by Oral Dosing at 200 Mg Twice Daily in Patients With Advanced HIV Infection”

To demonstrate a dosage regimen for intravenous itraconazole that produces a plasma concentration range comparable to that obtained after currently used oral dosages of itraconazole oral solution; and to obtain preliminary safety data in patients with advanced HIV disease.
