Due to low immune function, inflammation-related clinical symptoms and signs are often not obvious, and pathogenic bacteria and infection focus are not clear. Fever may be the only sign of infection. If appropriate antimicrobial treatment is not given in time, infection-related mortality is high. In our study, we aimed to optimize the dosage regimen of Micafungin in children with febrile neutropenic against Candida spp. by Mote Carlo Simulation (MCS). Pharmacokinetic parameters and microbiological data of Micafungin were collected. Then we used MCS to calculate Probability of Target Attainment (PTA) and Cumulative Fraction of Response (CFR). With dosages of 0.5 mg/kg, 1 mg/kg, 1.5 mg/kg, 2 mg/kg, 3 mg/kg, and 4 mg/kg in oral group and dosages of 100 mg, and 200 mg in intravenous administration, all have different degree of antifungal effect. But when the dosage regimen was 50 mg IV, the therapeutic effect of Micafungin against Candida spp. was not good.展开更多
