Background: The objective of the current study is to elucidate the effect that the adoption of generic drugs by a large hospital has on the dispensation of generic drugs by community pharmacies. We evaluated the percentage of generic drugs dispensed by pharmacies and the cost of drugs dispensed before and after the adoption of generic drugs by a large hospital. Methods: Participants comprised patients who were admitted to Gifu Municipal Hospital prior to its adoption of generic drugs (November 1, 2013 to November 14, 2013) and after its adoption (November 1, 2014 to November 14, 2014) and who utilized generic drugs dispensed by pharmacies...

INTRODUCTION: Treatment of acute organophosphorus or carbamate insecticide self-poisoning is often ineffective, with tens of thousands of deaths occurring every year. Researchers have recommended the addition of magnesium sulfate or calcium channel blocking drugs to standard care to reduce acetylcholine release at cholinergic synapses. OBJECTIVE: We aimed to review systematically the evidence from preclinical studies in animals exposed to organophosphorus or carbamate insecticides concerning the efficacy of magnesium sulfate and calcium channel blocking drugs as therapy compared with placebo in reducing mortality or clinical features of poisoning...

Treatment options for patients with HIV-1 infection have grown over the past two decades to include multiple fixed-dose combination pharmacotherapies that have greatly simplified administration of antiretroviral therapy (ART) for both patients and providers. Effective virologic control can often be achieved with once-daily use of a single-tablet regimen. Over the past three years, ART drug development has focused on the next generation of fixed-dose combinations for initial and maintenance therapy with improved efficacy, safety and tolerability...

Generic immunosuppressive drugs are available in Europe Canada and the United States. Between countries, there are large differences in penetration of generic drugs in general, and for immunosuppressive drugs in particular. The registration for generic immunosuppressive drugs are slightly different, but the criteria for registration of narrow therapeutic index drugs and bioequivalence studies, performed only in healthy volunteers, will remain in the medical landscape. About 50 studies compare the clinical efficacy and bioequivalence of the generic immunosuppressive drugs in patients with solid organ transplants...

G protein-coupled receptors (GPCRs) are of great importance to the pharmaceutical industry as they are involved in many human diseases and include well-validated targets for therapeutic intervention. Discovery of lead compounds, including small synthetic molecules, that specifically inhibit the receptor's function, is an important initial step in drug development and relies on sensitive, specific, and robust cell-based assays. Here, we describe a kinetic cellular assay with a fluorescent readout primarily designed to identify receptor-specific antagonists that inhibit the intracellular Ca2+ release evoked upon the activation of the CXC chemokine receptor 4 (CXCR4) by its endogenous ligand, the CXC chemokine ligand 12 (CXCL12)...

Epilepsy is associated with a significant increase in morbidity and mortality. The likelihood is significantly greater for those patients with specific risk factors. Identifying those at greatest risk of injury and providing expert management from the earliest opportunity is made more challenging by the circumstances in which many such patients present. Despite increasing recognition of the importance of earlier identification of those at risk, there is little or no improvement in outcomes over more than 30 years...

Time-resolved analysis assays of receptor-ligand interactions are fundamental in basic research and drug discovery. Adequate methods are well developed for the analysis of recombinant proteins such as antibody-antigen interactions. However, assays for time-resolved ligand-binding processes on living cells are still rare, in particular within microbiology. In this report, the real-time cell-binding assay (RT-CBA) technology LigandTracer®, originally designed for mammalian cell culture, was extended to cover Gram-positive and Gram-negative bacteria...

The safety of anesthesia characteristic of high-income countries today is not matched in low-resource settings with poor infrastructure, shortages of anesthesia providers, essential drugs, equipment, and supplies. Health care is delivered through complex systems. Achieving sustainable widespread improvement globally will require an understanding of how to influence such systems. Health outcomes depend not only on a country's income, but also on how resources are allocated, and both vary substantially, between and within countries...

Over recent years, drug names have become more complex and difficult to pronounce (e.g. axicabtagene ciloleucel, ▼rurioctocog alfa pegol, ▼riociguat ).1,2 Although some rules underpin drug nomenclature, there are several examples of drugs with similar sounding names that are easily confused. In addition, the different levels of nomenclature (chemical, generic and brand names) may cause confusion for patients. Here, we provide an overview of how drugs get their names, the patterns that can be seen in naming conventions and highlight the risk associated with drugs with similar looking or similar sounding names...

Saturation transfer difference (STD) NMR constitutes one of the most popular ligand-based NMR techniques for the study of protein-ligand interactions. This is due to its robustness and the fact that it is focused on the signals of the ligand, without any need for NMR information of the macromolecular target. This technique is most commonly applied to systems involving different types of ligands (e.g. small organic molecules, carbohydrates, or lipids) and a protein as the target, where the latter is selectively saturated...

Abstract: Allergen immunotherapy (AIT) is the only disease-modifying treatment approved for allergic rhinitis and allergic asthma and represents a suitable therapeutic option, especially in childhood, to modify the progression of respiratory allergic diseases. Starting from the previous "generic class effect" evaluation, as testified by the numerous meta analyses, AIT is now considered a product-specific pathogenic-oriented treatment. Background: AIT was empirically proposed more than one century ago in the subcutaneous form (SCIT), but the IgE-mediated mechanism of allergy was elucidated only after 50 years of clinical use of the treatment...

INTRODUCTION: Gay and bisexual men (GBM) often use illicit drugs to enhance sexual pleasure, commonly referred to as 'chemsex' or 'party n play'. In particular, the use of methamphetamine and Viagra™, and other erectile dysfunction medications, both together and separately are strongly predictive of subsequent HIV infection. Truvada™, as pre-exposure prophylaxis (PrEP), virtually eliminates HIV transmission during condomless anal intercourse (CLAI). HIV-negative GBM in intensive sex partying networks may be adding PrEP to their drug regimen to actively reduce the possibility of HIV transmission during chemsex...

Adherence to antiretroviral (ARV) is crucial to achieve viral load suppression in HIV-infected patients. This study aimed to compare adherence to generic multi-tablet regimens (MTR) ver-sus brand MTR likely to incorporate ARV drugs without breaking fixed-dose combinations (FDC) and brand single-tablet regimens (STR) likely to incorporate generics by breaking the FDC. Patients aged of 18 years or over, exposed to one of the generic or the brand of lamivu-dine (3TC), zidovudine/lamivudine (AZT/TC), nevirapine (NVP), or efavirenz (EFV), or the brand STR of efavirenz/emtricitabine/tenofovir (EFV/FTC/TDF)...

BACKGROUND: Inappropriate use of antibiotics is a global public health challenge and has been associated with antibiotic resistance. WHO reports show that efforts to promote rational antibiotic use in developing countries are poor. With the growing number of infections with antibiotic resistant bacteria, rational drug use becomes imperative and studies that promote rational drug use are highly necessary. Considering this, we investigated prescribing patterns and predictors of antibiotic prescription in primary health care facilities in Kumbo East (KE) and Kumbo West (KW) health districts in North West Cameroon, to contribute data which could influence policy on antibiotic use...

Generic drug products are expected to have the same active pharmaceutical ingredient (API) (Q1) with the same content (Q2) and microstructure arrangement (Q3) as the innovator product. In complex oil-in-water emulsion drugs, the hydrophobic API is mainly formulated in oil droplets stabilized by surfactant and micelles composed of extra surfactant molecules. The API phase partition in oil and water (mainly micelle) is a critical quality attribute (CQA) of emulsion product in demonstrating physicochemical equivalence using difluprednate (DFPN) emulsion product Durezol® as a model, we developed a novel low-field benchtop NMR method to demonstrate its applicability in measuring DFPN phase partition for ophthalmic oil-in-water emulsion products...
