Therapeutic drug monitoring is not routinely used for chemotherapy agents. There are Several reasons, but one major drawback is the lack of established therapeutic Concentration ranges. Combination chemotherapy makes the establishment of Therapeutic ranges for individual drugs difficult, the concentration-effect relationship for a single drug may not be the same as when that drug is used in a d...

Therapeutic Drug Monitoring (TDM) is a routinely practised clinical laboratory technique which aids the clinicians with a clear clinical judgement of the drug therapy and optimize the doses if necessary. Rifampicin is the most important and potent component of first line therapy of tuberculosis (TB). Several factors like age, weight, gender, doses and formulations, gastro-intestinal disorders, ...

We measured the concentrations of phenobarbital, phenytoin, primidone, ethosuximide, antipyrine, and caffeine in paired samples of saliva and plasma by gas chromatograph-mass spectrometer-computer (GC/MS/COM) and enzyme immunoassay. Mixed saliva was collected for the antipyrine and caffeine studies, parotid saliva for the phenobarbital, primidone, ethosuximide and phenytoin studies. The saliva/...

Numerous physiological changes during the normal aging process can potentially affect how drugs are handled by the body. Gastrointestinal changes include increased gastric pH, decreased intestinal motility, and decreased blood perfusion. Age-related changes in body composition and protein concentrations in plasma contribute to alterations in the distribution of drugs. Hepatic metabolism of drug...

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...

Therapeutic drug monitoring (TDM) is the measurement of serum or plasma drug concentration to allow the individualization of dosing. We describe the case of a patient who was prescribed inappropriately large doses of vancomycin due to inaccurate TDM. Specifically, our laboratory reported progressively lower vancomycin concentrations despite dose increases. Eventually, when duplicate samples wer...

Schizophrenia is a severe psychiatric disorder often associated with cognitive impairment and affective, mainly depressive, symptoms. Antipsychotic medication is the primary intervention for stabilization of acute psychotic episodes and prevention of recurrences and relapses in patients with schizophrenia. Typical antipsychotics, the older class of antipsychotic agents, are currently used much ...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Editorial Vancomycin and teicoplanin are the glycopeptides currently in use for the treatment of infections caused by beta-lactam-resistant gram-positive organisms [1]. Teicoplanin, a glycopeptide antibiotic, has a lower possibility than vancomycin to cause ...
