Nabumetone and 6-MNA Pharmacokinetics, Assessment of Intrasubject Variability and Gender Effect.

In this open-label, laboratory-blinded, 2-way single dose study in 24 volunteers of both sexes we found that (1) nabumetone reaches mean Cmax ± SD of 0.56 ± 0.20 mg·L at mean tmax of 8.

Pharmacogenetics and immunosuppressive drugs.

Several candidate genes have been proposed as potential biomarkers for altered pharmacodynamics or pharmacokinetics of immunosuppressive drugs. However, there is usually only limited clinical evidence substantiating the implementation of biomarkers into clinical practice. Testing for thiopurine-S-methyltransferase polymorphisms has been put into routine clinical use quite widely, while the other pharmacogenetic tests are much less frequently used.

Eye movements in ephedrone-induced parkinsonism.

Patients with ephedrone parkinsonism (EP) show a complex, rapidly progressive, irreversible, and levodopa non-responsive parkinsonian and dystonic syndrome due to manganese intoxication. Eye movements may help to differentiate parkinsonian syndromes providing insights into which brain networks are affected in the underlying disease, but they have never been systematically studied in EP. Horizontal and vertical eye movements were recorded in 28 EP and compared to 21 Parkinson's disease (PD) patients, and 27 age- and gender-matched healthy subjects using standardized oculomotor tasks with infrared videooculography.

The effect of postoperative pain treatment on the incidence of anastomotic insufficiency after rectal and rectosigmoideal surgery.

The aim of prospective study was to evaluate the pain relief in the postoperative period and consumption of opioid and non-opioid analgesics as a risk factor of the anastomotic insufficiency after rectal and rectosigmoideal resection for carcinoma. Anastomotic insufficiency is one of the most feared and life threatening early complications. No articles about the effect of the response to opioid therapy in the postoperative period on the risk of this major clinical problem have been published.

Pharmacogenetics of chronic pain and its treatment.

This paper reviews the impact of genetic variability of drug metabolizing enzymes, transporters, receptors, and pathways involved in chronic pain perception on the efficacy and safety of analgesics and other drugs used for chronic pain treatment. Several candidate genes have been identified in the literature, while there is usually only limited clinical evidence substantiating for the penetration of the testing for these candidate biomarkers into the clinical practice. Further, the pain-perception regulation and modulation are still not fully understood, and thus more complex knowledge of genetic and epigenetic background for analgesia will be needed prior to the clinical use of the candidate genetic biomarkers.
