Abstract:myPKFiT is a hemophilia A management tool under the guidance of pharmacokinetic (PK), which can quickly and accurately output patient PK parameters and dosing schedules for clinical reference. The current standard treatment for hemophilia A is preventive treatment. However, due to the influence of differences between individuals, calculating the dosage of coagulation factor Ⅷ (FⅧ) based on body weight alone cannot meet the individualized treatment needs of patients with hemophilia A. PK parameters can help clinicians better formulate individualized treatment plans, thereby improving the treatment effect and quality of life of patients with hemophilia. This article will give an overview of the progress of using myPKFiT to analyze PK to guide personalized medicine for patients with hemophilia A.
