In the present study, a novel, fast, sensitive and robust method to quantify clozapine in human plasma using quetiapine as the internal standard (IS) is described. The analyte and the IS were extracted from plasma using a single protein precipitation extraction technique with methanol and analyzed by high performance liquid chromatography coupled to the electrospray ionization tandem mass spectrometric (HPLC-ESI-MS/ Read More

Over the years Renal Transplant has become increasingly successful and fairly routine in terms of availability to prospective patients. More effective and better tolerated medications have led to decreased adverse immunologic events after transplant leading to improved graft survival. Moreover, since the last few years renal transplant is being offered to a wider range of patients with variety of comorbidities, thus making the surv Read More

Patent ductus arteriosus is a common problem in very low birth weight infants. Prostaglandin synthesis inhibitors such as indomethacin and ibuprofen are widely used preferred medications for ductal closure but the question of which one should be preferred is controversial. There are some studies in the literature comparing their pharmacokinetics, efficacy, side effects and long-term outcomes. In this review we aimed Read More

Interleukin (IL)-1 is a pivotal proinflammatory cytokine consisting of two molecular species, IL-1α and IL-1β. Anakinra (Kineret), a recombinant human IL-1 receptor antagonist, is regarded as a biological agent which blocks the inflammatory effects of IL-1. The aim of this review was to search the literatures and summarizes in vivo, in vitro and human studies on anakinra uses in dermatological disorders. The results sho Read More

Drug-related problems (DRPs) can reduce the potential clinical benefits of treatment with medicines and waste valuable resources. No previous studies were published to examine the nature and frequency of drug related problems among hospitalized patients in Palestinian hospitals. Methodology: Prospective observational study was conducted to report and record the natural and frequency of drug related problems i Read More

This review describes the most important new generations of pharmaceutical systems: medicines with extended release, controlled release pharmaceutical systems, pharmaceutical systems for the targeted delivery of drug substances. The latest advances and approaches for delivering small molecular weight drugs and other biologically active agents such as proteins and nucleic acids require novel delivery technologies, Read More

Autoimmune hepatitis is an immune-mediated disease targeting hepatocytes. It is more common in middleaged Caucasian females, although may affect other patient populations and age groups. The diagnosis is made according to criteria based on the alkaline phosphatase: ALT ratio, IgG, the presence of autoantibodies, liver histology, response to therapy, and the absence of a viral, alcohol or drug etiology. More recently a sim Read More

This paper describes the main development steps of pharmacokinetics that paralleled the development of analytical bioassay methods. From the first stirrings on 1950s, with very sensitive but not specific radiotracing measurements using 14C or 3H labelled drugs, to further developments with more specific methods like gas chromatography, high pressure liquid chromatography, to the last achievement with tandem mass spect Read More

DNA methylation is a major epigenetic mechanism that leads to inhibition of gene transcription and is known to be involved in the pathogenesis of cancer. The effectors of DNA methylation are DNA methyltransferases (DNMTs) that catalyze either de novo or maintenance methylation of hemimethylated DNA after DNA replication. DNA methylation patterns in cancer are distorted, with three ways by which DNA methylatio Read More
