Participation of quetiapine in oxidative stress and inflammation status in the treatment of drug overdose
Quetiapine (QT) belongs to the second generation of antipsychotics. It is mostly used to treat depression, bipolar disorder, and schizophrenia. During biotransformation via myeloperoxidase (MPO) QT is oxidized to quinoneimine and a reactive radical, which may contribute to the development of oxidative stress during intoxication. The coexisting inflammation may also significantly contribute to the disturbances in the course of QT poisoning. In this study, twenty-one patients poisoned with quetiapine were examined. The study aimed to assess the correlation between blood QT concentration and selected oxidative stress as well as inflammation biomarkers, such as MPO and C-reactive protein (CRP) levels in the serum of poisoned patients. The obtained results were related to the values of the control group consisting of 21 healthy people, untreated and not poisoned with the drug. In patients with a toxic QT concentration in the blood (3.15 ± 2.11 μg/mL), the activity of MPO and CRP serum level were significantly higher in comparison to the control group. The mean level of CRP in the study group was 76.74 mg/L, while in the control group only 1.86 mg/L. The increase in MPO activity and CRP blood level in patients after QT overdose may confirm the hypothesis of oxidative disorders arising during its biotransformation and concomitant inflammation. Statistically significant relationships between selected biomarkers and blood QT concentration, the patient's clinical condition and the type of therapy were demonstrated.
期刊介绍:
The international journal of the Polish Pharmaceutical Society is published in 6 issues a year. The journal offers Open Access publication of original research papers, short communications and reviews written in English, in all areas of pharmaceutical sciences. The following areas of pharmaceutical sciences are covered: Analysis, Biopharmacy, Drug Biochemistry, Drug Synthesis, Natural Drugs, Pharmaceutical Technology, Pharmacology and General.
A bimonthly appearing in English since 1994, which continues “Acta Poloniae Pharmaceutica”, whose first issue appeared in December 1937. The war halted the activity of the journal’s creators. Issuance of “Acta Poloniae Pharmaceutica” was resumed in 1947. From 1947 the journal appeared irregularly, initially as a quarterly, then a bimonthly. In the years 1963 – 1973 alongside the Polish version appeared the English edition of the journal. Starting from 1974 only works in English are published in the journal. Since 1995 the journal has been appearing very regularly in two-month intervals (six books a year). The journal publishes original works from all fields of pharmacy, summaries of postdoctoral dissertations and laboratory notes.
