Published: April 2019

A range of generic valsartan products have been found to be contaminated with nitrosamines (principally N-nitrosodimethylamine; NDMA). We present information and discuss various elements of this phenomenon including: actions taken by regulatory agencies, source of the nitrosamine impurities, range of possible risk assessments based mainly on ICH M7 criteria, epidemiological assessment and analytical aspects.

Introduction: The cardiotoxicity and subsequent Heart Failure (HF) induced by Doxorubicin (DOX) limit the clinical application of DOX. Valsartan (Val) is an angiotensin II receptor blocker that could attenuate the HF induced by DOX. However, the underlying mechanism of Val in this process is not fully understood.

Background: There is evidence supporting the efficacy of Sacubitril /Valsartan for improving left heart failure, but few studies have examined its effects on right ventricular (RV) dysfunction. The current study aimed to investigate the effects of Sacubitril /Valsartan on RV dysfunction in patients with right heart failure.

Methods: The current study was a randomized and parallel clinical trial study.

Introduction: With the increasing prevalence of hypertension, the incidence of kidney diseases is also increasing, resulting in a serious public burden. Jiangya Tongluo decoction (JYTL), a recognized prescription in traditional Chinese medicine (TCM), is commonly used to calm an overactive liver and reduce excess yang, while also promoting blood flow to alleviate obstructions in the meridians. Previous research has indicated that JYTL may help mitigate kidney damage caused by hypertension; however, the underlying mechanisms have not been thoroughly assessed.

This research study critically evaluates the concentrations of selected pharmaceuticals found within wastewater and at various stages within a selected wastewater treatment plant. The study further investigates the effects of seasonal variation, between wet and dry months, on the removal of target analytes. To the best of the authors' knowledge, ivermectin in wastewater has not been investigated in South Africa.

Doping of carbon dots (CDs) with heteroatoms has garnered growing attention in recent years as a useful method of controlling their physicochemical properties. In this study, a new dual-mode sensor based on silver-doped CDs (AgCDs) derived from lignin was developed for fluorometric and spectrophotometric determination of valsartan (VAL). The analysis of AgCDs revealed a structure that closely resembled graphene oxide, with the successful doping of Ag.
