REVIEW
Martin Mayer
BACKGROUND: The most recent joint guidelines from the American Heart Association (AHA) and American College of Cardiology (ACC) on the management of non-ST-elevation acute coronary syndromes (NSTE-ACS) are a result of a substantial and considered undertaking, and those involved deserve much recognition for their efforts. However, the handling of anticoagulants seems somewhat inadequate, and this is a highly-relevant matter when managing NSTE-ACS. OBJECTIVE OF THE REVIEW: Among areas of potential uncertainty, emergency medicine professionals might still be left wondering about the particulars of anticoagulant therapy when pursuing ischemia-guided management of NSTE-ACS (that is, managing NSTE-ACS without an intent for early invasive measures, such as coronary angiography and revascularization)...

The aim of this study was to apply quality by design (QbD) for pharmaceutical development of enoxaparin sodium microspheres for colon-specific delivery. The Process Parameters (CPPs) and Critical Quality Attributes (CQAs) were identified. A central composite experimental design was used in order to develop the design space of microspheres for colon-specific delivery that have the desired Quality Target Product Profile (QTPP). The CPPs studied were Eudragit® FS-30D/Eudragit® RS-PO ratio, poly(vinyl alcohol) (PVA) concentration and sodium chloride (NaCl) concentration...

Heparin and its low-molecular-weight heparin (LMWH) derivatives are widely used clinical anticoagulants. These drugs are critical for the practice of medicine in applications including kidney dialysis, cardiopulmonary bypass, and in the management of venous thromboembolism. Currently, these drugs are derived from livestock, primarily porcine intestine. The worldwide dependence on a single animal species has made the supply chain for this critical drug quite fragile, leading to the search for other sources of these drugs, including bovine tissues such as bovine intestine or lung...

PURPOSE: Traditional anticoagulants used in intermittent hemodialysis (HD) are unfractionated heparin (UFH) and increasingly low molecular weight heparins (LMWHs). Repeated and prolonged exposure to UFH and/or LMWHs may further disturb hemostasis in uremic patients. Vascular adhesion protein-1 (VAP-1) is secreted by vascular smooth muscle cells, adipocytes and endothelial cells with functional monoamine oxidase activity and is elevated in atherosclerosis, diabetes mellitus and obesity...

American College of Chest Physicians Evidence-Based Clinical Practice Guidelines, 9th edition, 2012, suggest no prophylaxis rather than pharmacological thromboprophylaxis in management of venous thromboembolism (VTE) risk of isolated lower leg injuries distal to knee requiring leg immobilization. Low-molecular-weight heparin (LMWH) is a class of drugs commonly used as antithrombotics in surgery and in case of prolonged bed rest and hypomobility. A 35-year-old obese man with no history of health disease (height, 170 cm; weight, 95 kg; and body mass index, 32...

Cationic copolymers have been attractive to investigate due to their potential to complexation with anionic drugs and expected to use in the pharmaceutical application. In this study, the modified poly(ε-caprolactone)2-co-poly(ethylene glycol) copolymers (P(CL)2-PEG) were successfully synthesized by click reaction. The amount of small molecular cationic ligand, propargyltrimethyl ammonium iodide, was varied and grafted onto various mole ratios of P(CL) to PEG. The effects of P(CL) chain length and amount of the grafting cationic ligand on physicochemical properties of polymers and particles were studied...

A strategy for the comprehensive analysis of low molecular weight (LMW) heparins is described that relies on using an integrated top-down and bottom-up approach. Liquid chromatography-mass spectrometry, an essential component of this approach, is rapid, robust, and amenable to automated processing and interpretation. Nuclear magnetic resonance spectroscopy provides complementary top-down information on the chirality of the uronic acid residues comprising a low molecular weight heparin. Using our integrated approach four different low molecular weight heparins prepared from porcine heparin through chemical β-eliminative cleavage were comprehensively analyzed...

INTRODUCTION: Evidence-based plastic surgery guidelines support the effectiveness of once daily enoxaparin prophylaxis. Despite prophylaxis, one in 25 highest risk patients has a VTE event. We examined the pharmacodynamics of standard enoxaparin doses in plastic surgery patients to examine whether patient-level factors predict enoxaparin metabolism, whether inadequate enoxaparin dose predicts downstream VTE events, and whether a pharmacist-driven dose adjustment protocol was effective...

INTRODUCTION: The aim of this study was to evaluate the cost-effectiveness of rivaroxaban and apixaban versus enoxaparin for the universal prophylaxis of venous thromboembolism (VTE) and associated long-term complications in Chinese patients after total hip replacement (THR). METHODS: A decision model, which included both acute VTE (represented as a decision tree) and the long-term complications of VTE (represented as a Markov model), was developed to assess the economic outcomes of the three prophylactic strategies for Chinese patients after THR...

To increase the encapsulation efficiency and oral absorption of doxorubicin hydrochloride (DOX), a novel drug delivery system of enoxaparin sodium-PLGA hybrid nanoparticles (EPNs) was successfully designed. By introducing the negative polymer of enoxaparin sodium (ES) to form an electrostatic complex with the cationic drug, DOX, the encapsulation efficiency (93.78%) of DOX was significantly improved. The X-ray diffraction (XRD) results revealed that the DOX-ES complex was in an amorphous form. An in vitro release (pH6...

Triathlon followers increase each year and long-distance events have seen major growth worldwide. In the cycling phase, athletes must maintain an aerodynamic posture on the bike for long periods of time. We report a case of a 38-year-old triathlete with symptoms of an axillary vein thrombosis 48h after a long triathlon competition. After 3days of hospitalization with a treatment consisted on enoxaparin anticoagulant and acenocumarol, the patient was discharged with instructions to continue treatment under home hospitalization with acetaminophen...

Heparin is a polysaccharide based anticoagulant drug composed of a complex mixture of glycosaminoglycan chains and peptidoglycosaminoglycan chains. In an effort to better characterize this important polysaccharide based drug, we examined the peptide components of the minor peptidoglycosaminoglycan chains comprising heparin. Three different the glycan-peptide linkage regions tetrasaccharide fragments were isolated from pharmaceutical heparin using heparin lyase II and characterized the structure of these tetrasaccharides using nuclear magnetic resonance spectroscopy and mass spectrometry...

METHODS: Thirty four rats were divided into three groups: Group 1 (sham) underwent insertion of Veress needle into the abdomen and 90 min of anesthesia with no gas insufflation. The animals in control and enoxaparin groups were subjected to 90 min of 14 mmHg CO2 pneumoperitoneum. Enoxaparin (100 u/kg) was administered subcutaneously to the rats in enoxaparin group one hour before the operation...

OBJECTIVES: Recent studies have revealed a relationship between beta-blocker use and worse prognosis in acute coronary syndrome, mainly due to a higher incidence of cardiogenic shock. However, the relevance of this relationship in the reperfusion era is unknown. The aim of this study was to analyze the outcomes of patients with acute coronary syndrome that started oral beta-blockers within the first 24 hours of hospital admission (group I) compared to patients who did not use oral beta-blockers in this timeframe (group II)...
