Staatz, e-mail: [email protected] Source of support: Departmental funding only Background: Increasing immunosuppressant utilization and expenditure is a worldwide challenge as more people success- fully live with transplanted organs. Our aims were to characterize utilization of mycophenolate, tacrolimus, cy- closporin, sirolimus, and everolimus in Australian transplant recipients from 2007 to 2013; to identify specific patterns of usage; and to compare Australian utilization with Norwegian, Danish, Swedish, and the Netherlands use. Material/Methods: Australian utilization and expenditure data were captured through national Pharmaceutical Benefits Scheme and Highly Specialized Drug administrative databases. Norwegian, Danish, Swedish, and the Netherlands uti- lization were retrieved from their healthcare databases. Utilization was compared as defined daily dose per 1000 population per day (DDD/1000 population/day). Data on kidney transplant recipients, the predominant patient group prescribed these medicines, were obtained from international transplant registries. Results: From 2007–2013 Australian utilization of mycophenolic acid, tacrolimus and everolimus increased 2.7-fold, 2.2- fold, and 2.3-fold, respectively.

  • COMPARISON of the WHO ATC CLASSIFICATION & Ephmra/Intellus Worldwide ANATOMICAL CLASSIFICATION
    COMPARISON OF THE WHO ATC CLASSIFICATION & EphMRA/Intellus Worldwide ANATOMICAL CLASSIFICATION: VERSION June 2019 2 Comparison of the WHO ATC Classification and EphMRA / Intellus Worldwide Anatomical Classification The following booklet is designed to improve the understanding of the two classification systems. The development of the two systems had previously taken place separately. EphMRA and WHO are now working together to ensure that there is a convergence of the 2 systems rather than a divergence. In order to better understand the two classification systems, we should pay attention to the way in which substances/products are classified. WHO mainly classifies substances according to the therapeutic or pharmaceutical aspects and in one class only (particular formulations or strengths can be given separate codes, e.g. clonidine in C02A as antihypertensive agent, N02C as anti-migraine product and S01E as ophthalmic product). EphMRA classifies products, mainly according to their indications and use. Therefore, it is possible to find the same compound in several classes, depending on the product, e.g., NAPROXEN tablets can be classified in M1A (antirheumatic), N2B (analgesic) and G2C if indicated for gynaecological conditions only. The purposes of classification are also different: The main purpose of the WHO classification is for international drug utilisation research and for adverse drug reaction monitoring. This classification is recommended by the WHO for use in international drug utilisation research. The EphMRA/Intellus Worldwide classification has a primary objective to satisfy the marketing needs of the pharmaceutical companies. Therefore, a direct comparison is sometimes difficult due to the different nature and purpose of the two systems.

  • Dimethyl Fumarate and Progressive Multifocal Leucoencephalopathy (PML)
    Dimethyl fumarate and progressive multifocal leucoencephalopathy (PML) Introduction Dimethyl fumarate Psorinovo® is not registered through the Medicines Evaluation Board (MEB). It is a compounded drug made by GMP compounding pharmacy Mierlo Hout in the Netherlands, and used for the indication psoriasis [1]. Psorinovo® has been compounded by pharmacy Mierlo Hout for 28 years. According to Dutch law Mierlo Hout pharmacy is regarded as a supplying-pharmacy. ® Dimethyl fumarate, registered as Tecfidera , was granted marketing authorization in the Netherlands on 30 January 2014 and is indicated for the treatment of adult patients with relapsing remitting multiple sclerosis [2]. Progressive multifocal leukoencephalopathy (PML) is a severe demyelinating disease of the central nervous system caused by reactivation of the polyomavirus JC (JC virus). Asymptomatic primary infection with the JC virus occurs in childhood, antibodies can be found in 86% of adults. PML occurs almost exclusively in immunosuppressed individuals. There were only isolated cases reported of PML in patients without apparent immunosuppression. However, there are reports of PML affecting patients who have conditions associated with minimal or occult immunosuppression, such as hepatic cirrhosis and renal failure [3]. PML has also been reported in patients treated with drugs such as belatacept, brentuximab, efalizumab, fludarabine, glucocorticoids, infliximab, mycophenolate, rituximab, ruxolitinib and natalizumab. In some cases, these drugs were used in combination with other immunosuppressive medications (eg, cyclophosphamide, leflunomide, methotrexate). Many of the patients had an underlying hematologic malignancy or collagen vascular disease [3]. There is no specific treatment for PML. The main approach is restoring the host adaptive immune response, a strategy that appears to prolong survival.

  • Thesis Outline
    PHARMACOKINETICS, LIMITED SAMPLING STRATEGIES, AND PHARMACOGENETICS OF MYCOPHENOLIC ACID IN THORACIC TRANSPLANT RECIPIENTS by LILLIAN S.L. TING M.Sc., The University of British Columbia, 2005 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in The Faculty of Graduate Studies (Pharmaceutical Sciences) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) March, 2009. © Lillian S.L. Ting, 2009 ABSTRACT Mycophenolic acid (MPA), the active metabolite of mycophenolate mofetil, is an immunosuppressive agent known to exhibit wide inter-patient pharmacokinetic variability. The metabolism and transport of MPA and the phenolic (MPAG) and acyl (AcMPAG) glucuronides are mediated by UDP-glucuronosyltransferases (UGTs) and multidrug resistance-associated protein 2 (MRP2/ABCC2), respectively. Increasing evidence supports monitoring MPA area-under-the-concentration-time-curve; however, it is impractical and costly to implement. The objectives of this clinical study were to characterize MPA pharmacokinetics, develop MPA limited sampling strategies for estimating MPA exposure, and assess contribution of UGT and ABCC2 genetics to MPA pharmacokinetics and clinical outcomes in thoracic transplant recipients. Seventy thoracic (36 lung, 34 heart) transplant recipients were recruited. Eleven blood samples were obtained over a 12-hour dosing period at steady state. Plasma concentrations of MPA, MPAG, AcMPAG, and free MPA were measured by a high performance liquid chromatography-ultraviolet detection method, and conventional dose- normalized pharmacokinetic parameters were determined via non-compartmental methods. Limited sampling strategies were developed in 64 subjects by stepwise multiple regression analysis using the index group data, and tested in the validation group to determine bias and precision. Genetic polymorphisms in UGT and ABCC2 were determined by sequencing and their contributions to pharmacokinetic variability were investigated in 68 thoracic transplant recipients using multivariate analysis.

  • Immunosuppressive Therapy DR
    OCTOBER 2017 Immunosuppressive Therapy DR. ANDREW MACKIN BVSc BVMS MVS DVSc FANZCVSc DipACVIM Professor of Small Animal Internal Medicine Mississippi State University College of Veterinary Medicine, Starkville, MS A number of established immunosuppressive agents have been used in small animal medicine for many decades. Some have justifiably fallen out of favor whereas, for others, new and promising uses have been described in the recent veterinary literature. Established “old favorites” have included cyclophosphamide, chlorambucil, azathioprine, danazol and vincristine, although cyclophosphamide and danazol are rarely used as immunosuppressive agents these days. Several potent immunosuppressive drugs developed over the past few decades in human medicine have recently made the leap to our small animal patients, and our use of drugs such as cyclosporine, leflunomide and mycophenolate is growing. Cyclophosphamide Cyclophosphamide, a cell-cycle nonspecific nitrogen mustard derivative alkylating agent, was one of the first major chemotherapeutic agents approved by the FDA over 50 years ago, and has since become very well-established in human medicine as both an antineoplastic drug and as an immunosuppressive agent. Within a few years of FDA approval in the late 1950s, the use of cyclophosphamide for the prevention of transplant rejection in experimental models and for the treatment of both neoplasia and immune-mediated diseases was described in both dogs and cats. Cyclophosphamide has persisted to this day as one of the core drugs used in many small animal cancer chemotherapeutic protocols. In contrast, after many years as one of the most commonly immunosuppressive drugs utilized to treat immune-mediated diseases in cats and dogs, the use of cyclophosphamide as an immunosuppressive agent in small animal patients has in the past two decades essentially faded away.
