Pharmacokinetic Characteristics and Limited Sampling Strategies for Therapeutic Drug Monitoring of Colistin in Patients With Multidrug-Resistant Gram-Negative Bacterial Infections.

abstract：:Thiopurine methyltransferase (TPMT) is a cytoplasmic enzyme that preferentially catalyzes the S-methylation of aromatic and heterocyclic sulphydryl compounds, such as the thiopurine drugs azathioprine, mercaptopurine, and thioguanine. These drugs form the same terminal metabolites, the thioguanine nucleotides (TGNs). ...
