Impact of CYP2C19 Genotype on Sertraline Exposure in 1200 Scandinavian Patients
www.nature.com/npp ARTICLE Impact of CYP2C19 genotype on sertraline exposure in 1200 Scandinavian patients Line S. Bråten 1,2, Tore Haslemo1,2, Marin M. Jukic3,4, Magnus Ingelman-Sundberg 3, Espen Molden1,5 and Marianne K. Kringen1,2 Sertraline is an (SSRI-)antidepressant metabolized by the polymorphic CYP2C19 enzyme. The aim of this study was to investigate the impact of CYP2C19 genotype on the serum concentrations of sertraline in a large patient population. Second, the proportions of patients in the various CYP2C19 genotype-deﬁned subgroups obtaining serum concentrations outside the therapeutic range of sertraline were assessed. A total of 2190 sertraline serum concentration measurements from 1202 patients were included retrospectively from the drug monitoring database at Diakonhjemmet Hospital in Oslo. The patients were divided into CYP2C19 genotype-predicted phenotype subgroups, i.e. normal (NMs), ultra rapid (UMs), intermediate (IMs), and poor metabolisers (PMs). The differences in dose-harmonized serum concentrations of sertraline and N-desmethylsertraline-to-sertraline metabolic ratio were compared between the subgroups, with CYP2C19 NMs set as reference. The patient proportions outside the therapeutic concentration range were also compared between the subgroups with NMs deﬁned as reference. Compared with the CYP2C19 NMs, the sertraline serum concentration was increased 1.38-fold (95% CI 1.26–1.50) and 2.68-fold (95% CI 2.16–3.31) in CYP2C19 IMs and PMs, respectively (p < 0.001), while only a marginally lower serum concentration (−10%) was observed in CYP2C19 UMs (p = 0.012). The odds ratio for having a sertraline concentration above the therapeutic reference range was 1.97 (95% CI 1.21–3.21, p = 0.064) and 8.69 (95% CI 3.88–19.19, p < 0.001) higher for IMs and PMs vs.

SERT and DSERT were extracted by an optimized solid phase chromatographic (SPE) method using C-18 cartridges and DSE SER Clomipramine was used as external standard (ES). The analytes ES were separated on C18, 4.6 mm × 150 mm, 5 µm column at 50 °C with a mobile phase of 45% acetonitrile + 55% NaH2PO4 at a flow rate of 0.4 mL/min. Detector responses monitored at 4 different wave-lengths; 200-205-210-215 nm. The method proved to be rapid and effective for the plasma sample analyses of therapeutic drug monitoring for sertraline treated patients.

Parkinson's Disease Fact Sheet
Parkinson’s Disease Fact Sheet About Parkinson’s Disease Parkinson’s disease is a progressive, incurable neurological disorder associated with a loss of dopamine-generating cells in the brain. It is primarily associated with progressive loss of motor control, but it results in a complex array of symptoms, including many non-motor symptoms. Parkinson’s impacts an estimated one million people in the United States. Critical Clinical Care Considerations • To avoid serious side effects, Parkinson’s patients need their medications on time, every time — do not skip or postpone doses. • Write down the exact times of day medications are to be administered so that doses are given on the same schedule the patient follows at home. • Do not substitute Parkinson’s medications or stop levodopa therapy abruptly. • Resume medications immediately following procedures, unless vomiting or severely incapacitated. • If an antipsychotic is necessary, use pimavanserin (Nuplazid), quetiapine (Seroquel) or clozapine (Clozaril). • Be alert for symptoms of dysphagia (trouble swallowing) and risk of pneumonia. • Ambulate as soon as medically safe. Patients may require assistance. Common Symptoms of Parkinson’s Disease Motor Non-Motor • Shaking or tremor at rest • Depression • Bradykinesia or freezing (being stuck • Anxiety in place when attempting to walk) • Constipation • Low voice volume or muffled speech • Cognitive decline and dementia • Lack of facial expression • Impulse control disorders • Stiffness or rigidity of the arms, legs • Orthostatic hypotension or
