Therapeutic drug monitoring (TDM) involves the measurement of plasma or serum drug concentration to adapt dosages to achieve predefined target concentrations that are associated with optimal clinical response while minimizing the chance of encountering toxicity. Many papers in the field of antifungal drugs have focused on the evidence that supports the use of TDM thereby emphasizing the breakpo...

Background Biologics have gained traction for use in oncology, but have demonstrate clinical variability for efficacy and safety. Therapeutic drug monitoring (TDM) can benefit patients' outcomes from a biologic therapy when the latter has a defined therapeutic window. A clinically relevant therapeutic window may exist for biologics with established exposure-response (E-R) relationships for effi...

While therapeutic drug monitoring (TDM) that uses blood as the biological matrix is the traditional gold standard, this practice may be impossible, impractical, or unethical for some patient populations (e.g., elderly, pediatric, anemic) and those with fragile veins. In the context of finding an alternative biological matrix for TDM, this manuscript will provide a qualitative review on: (1) the...

(1) Background: The concentration of amisulpride, an atypical antipsychotic drug, is most often determined in the blood, with many inconveniences. An alternative may be to use saliva as a diagnostic material for this purpose. development method determine amisulpride using small volume biological could significantly improve patient comfort during Therapeutic Drug Monitoring (TDM). (2) Methods: T...

Schizophrenia is a common disease, characterized by progressive functional decline exacerbated by psychotic relapses that often result from a lack of full adherence to antipsychotic (APS) medication. Although atypical APS medications do not have clear therapeutic windows, as generally required for therapeutic drug monitoring (TDM), measuring APS plasma levels in the context of a population expe...

Therapeutic drug monitoring (TDM) is the clinical practice of measuring drug concentrations or metabolites to attain a targeted concentration in a patient's bloodstream, thereby optimizing individual dosage regimens. With the well-established knowledge of the relationship of the genetic variability of thio-purine metabolism driven by the thiopurine S-methyltransferase pathway, and the recent da...

Several factors can limit the use of therapeutic drug monitoring (TDM) for cancer chemotherapeutic agents, including poorly defined concentration-effect relationships for many antineoplastic agents. This is further complicated by cancer being a highly heterogeneous group of diseases, each of which may have a unique concentration-effect relationship for any given drug or drug combination. Noneth...

Medications used to treat and prevent seizures (antiepileptic medications, AEMs) have been commonly managed by therapeutic drug monitoring (TDM) to optimize efficacy and avoid toxicity (Neels et al., 2004; Patsalos et al., 2008). TDM has been applied mostly to the firstgeneration AEMs that have been used clinically in the United States and Europe for several decades, namely carbamazepine, ethos...
