Sepsis and septic shock patients are considered to have a high risk of complications and death. Appropriate antimicrobial therapy plays an important role in determining outcomes in septic patients. However, pathophysiologic changes associated with critical illness have an impact on pharmacokinetics of antimicrobials. In addition, increasing bacterial resistance is also a growing concern, especially in intensive care units., Consequently, standard antimicrobial dose may not be sufficient to achieve pharmacokinetic/pharmacodynamic target in sepsis and septic shock patients. The purpose of this study is to compare a therapy between meropenem standard dose and meropenem high dose in the treatment of sepsis and septic shock
Tacrolimus is a calcineurin inhibitor widely used for the prevention of allograft rejection in solid organ and bone marrow transplantation. It is characterized by a narrow therapeutic index and large inter-individual pharmacokinetic variability. Adoport® is an immediate-release formulation of tacrolimus, to be administered twice daily. Because of a narrow therapeutic window and a better correlation between pre-dose level and effects than between dose and effect, therapeutic drug monitoring (TDM) based on trough whole blood tacrolimus concentrations is recommended for Adoport®. TDM helps to minimize the risk of acute rejection and the occurrence of adverse effects (mainly nephrotoxicity and, to a lesser extent, neurotoxicity). As reported in a consensus document from a consortium of European experts on tacrolimus TDM, the interdose area-under-the curve (AUC0-12h) is expected to be the best marker of tacrolimus exposure. However, tacrolimus monitoring based on full AUC0-12h is difficult to set up in routine, due to clinical constraints and the necessity of multiple samples. Calculation of the AUC0-12h using Bayesian estimation and a limited sampling strategy, i.e. a few blood samples collected during the early phase post-dose would represent an elegant solution, as already done for other tacrolimus formulations. Furthermore, the pharmacokinetics (PK) of tacrolimus is influenced by a single nucleotide polymorphism within intron 3 of cytochrome P450 3A5 (CYP3A5). Patients who carry at least one CYP3A5*1 allele are considered to be CYP3A5 expressors (about 12% of the Caucasian population, Hapmap project) and thus require a 1.5 to 2-fold higher starting dose than CYP3A5*3/*3 carriers to reach the predefined target exposure early after transplantation. Although this polymorphism showed no impact on the performance of the Bayesian estimators previously developed for other tacrolimus formulation, the patient status for CYP3A5*3 will be considered in this pharmacokinetic study as a potential covariate in, or confounding factor of, the PK model. Specifically, owing to a 12% frequency in the White European population, about 4 patients carriers of the CYP3A5*1 allele are expected in this study; the performance of the PK model and Bayesian estimator developed will be specifically evaluated in this subgroup.

Cohort 1 To evaluate the pharmacokinetic interactions of CJ-12420 after multiple oral doses of CJ-12420 given alone or in combination with amoxicillin/clarithromycin in healthy subjects. Cohort 2 To evaluate the pharmacodynamic profiles of CJ-12420 after multiple oral doses of CJ-12420 in combination with amoxicillin/clarithromycin in healthy subjects as compared to an active control group, i.e., pantoprazole in combination with amoxicillin/clarithromycin.
Primary Objective - To characterize the potential pharmacokinetic interactions of artemether -lumefantrine, amodiaquine and primaquine in healthy adult subjects. Secondary Objectives - To characterize the pharmacokinetic properties of artemether-lumefantrine, amodiaquine and primaquine when given alone and in combination. - To evaluate the safety and tolerability of co-administered artemether-lumefantrine, amodiaquine and primaquine. - To investigate pharmacogenetic polymorphisms affecting drug levels of artemether-lumefantrine, amodiaquine and primaquine and their metabolites.
The purpose of this study in healthy people is to investigate the safety, toleration and time course of UK-396,082 concentration in the blood and any changes in relevant markers of drug effects, following multiple doses given twice daily by mouth for 14 days.
Diabetes mellitus is a growing global disease now and future, and in China, 1.2 million peoples per year have been diagnosed as diabetes mellitus. 90% diabetes mellitus patient is Type 2 diabetes mellitus. Glipizide is a potent drug to service patients who suffer from Type 2 disease. Little information has been presented for the relationship between CYP2C19 genetic polymorphism and glipizide, since recently the investigators reported that there existed a tendency. In this study the investigators found that CYP2C19 polymorphism significantly influenced the pharmacokinetics of glipizide.
