BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs), e.g. sofosbuvir, are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may eradicate hepatitis C virus (HCV) from the blood (sustained virological response). Sustained virological response (SVR) is used by investigators and regulatory agencies as a surrogate outcome for morbidity and mortality, based solely on observational evidence...

In 2004, 2011, and 2017, the Arbeitsgemeinschaft für Neuropsychopharmakologie und Pharmakopsychiatrie (AGNP), a group of German-speaking psychiatric researchers and psychiatrists, published successive versions of therapeutic drug monitoring (TDM) expert group consensus guidelines. The 2017 version has as a major strength its encyclopedic nature, including 1358 references. The guideline has 3 major sections: 1) theoretical aspects of TDM, 2) drug concentration levels in blood to guide neuropsychopharmacotherapy, and 3) practical aspects of TDM in psychiatry and neurology...

BACKGROUND AND AIMS: Hepatitis C virus (HCV) infection is a common condition with endemic prevalence in some areas of the world. In Romania, the mean prevalence is about 3%. New treatments have become available on the market in recent years and new drugs are in the pipeline. A re-evaluation of HCV therapy was considered mandatory. The Romanian Society of Gastroenterology and Hepatology undertook this task for the practitioners of this country. METHODOLOGY: A group of recognized experts was created who screened the available literature and the major available guidelines...

For a new candidate drug to become an approved medicine, several decision points have to be passed. In this article, we focus on two of them: Firstly, based on Phase II data, the commercial sponsor decides to invest (or not) in Phase III. Secondly, based on the outcome of Phase III, the regulator determines whether the drug should be granted market access. Assuming a population of candidate drugs with a distribution of true efficacy, we optimize the two stakeholders' decisions and study the inter-dependence between them...

The increasing understanding of the molecular biology and the etiopathogenetic mechanisms of asthma helps in identification of numerous phenotypes and endotypes, particularly for severe refractory asthma. For a decade, the only available biologic therapy that met the unmet needs of a specific group of patients with severe uncontrolled allergic asthma has been omalizumab. Recently, new biologic therapies with different mechanisms of action and targets have been approved for marketing, such as mepolizumab. Other promising drugs will be available in the coming years, such as reslizumab, benralizumab, dupilumab and lebrikizumab...

Urea-cycle disorders are a group of rare hereditary metabolic diseases characterized by deficiencies of one of the enzymes and transporters involved in the urea cycle, which is necessary for the removal of nitrogen produced from protein breakdown. These hereditary metabolic diseases are characterized by hyperammonemia and life-threatening hyperammonemic crises. Pharmacological treatment of urea-cycle disorders involves alternative nitrogen-scavenging pathways. Sodium benzoate combines with glycine and phenylacetate/phenylbutyrate with glutamine, forming, respectively, hippuric acid and phenylacetylglutamine, which are eliminated in the urine...

In Korean traditional medicine, though herbal decoction, acupuncture, and moxibustion are all used to treat diseases, restorative medicines are the most widely preferred treatment method. This paper explores the historical background of restorative herbal medicines and ginseng among the Korean public and Korean traditional medicine practice. It also seeks to clarify how social and cultural perspectives on drug use have changed since restorative medicine became mainstream during the Joseon era. Drug use tendencies were affected by the medical system of the Joseon Dynasty, patients' desires for reliable treatment, and perceptions of the human body and the causes of disease...

Particle size reduction of drug crystals in the presence of surfactants (often called "top-down" production methods) is a standard approach used in the pharmaceutical industry to improve bioavailability of poorly soluble drugs. Based on the mathematical model used to predict the fraction dose absorbed this formulation approach is successful when dissolution rate is the main rate limiting factor of oral absorption. In case compound solubility is also a major factor this approach might not result in an adequate improvement in bioavailability...

Schistosomiasis, which is caused by helminth trematode blood flukes of the genus Schistosoma, is a serious health and economic problem in tropical areas, and the second most prevalent parasitic disease after malaria. Currently, there is no effective vaccine available and treatment is entirely dependent on a single drug, praziquantel (PZQ), raising a significant potential public health threat due to the emergence of PZQ drug resistance. It is thus urgent and necessary to explore novel therapeutic targets for the treatment of schistosomiasis...
