Many studies have quantified pharmaceuticals in the environment, few however, have incorporated detailed temporal and spatial variability due to associated costs in terms of time and materials. Here, we target 33 physico-chemically diverse pharmaceuticals in a spatiotemporal exposure study into the occurrence of pharmaceuticals in the wastewater system and the Rivers Ouse and Foss (two diverse river systems) in the city of York, UK. Removal rates in two of the WWTPs sampled (a conventional activated sludge (CAS) and trickling filter plant) ranged from not eliminated (carbamazepine) to >99% (paracetamol)...

Prodrug activation by exogenously administered enzymes for cancer therapy is an approach to achieve better selectivity and less systemic toxicity than conventional chemotherapy. However, the short half-lives of the activating enzymes in bloodstream has limited its success. Here, we demonstrate that a tyrosinase-MOF nanoreactor activates the prodrug paracetamol in cancer cells in a long-lasting manner. By generating reactive oxygen species (ROS) and depleting glutathione (GSH), the product of enzymatic conversion of paracetamol is toxic to drug-resistant cancer cells...

Paracetamol (acetaminophen) is one of the most commonly used analgesics in Europe; however, both the safety and efficacy of paracetamol have recently been questioned. Little is known about cross-national differences in the sales of paracetamol. Using national wholesale statistics and nationwide prescription drug registers, we investigated trends in total and prescribed use of paracetamol in the Nordic countries. The total sales of paracetamol (Anatomical Therapeutic Chemical (ATC) classification system code: N02BE01) measured as defined daily doses (DDD) per 1000 inhabitants/day, and the sales by prescription (users per 1000 inhabitants per year), increased in the Nordic countries from 2000 to 2015...

AIMS: To describe consumption trends of three groups of analgesics (non-opioids, mild and strong opioids) between 2006 and 2015 in France, and compare this pattern of use with six European countries in 2015. METHODS: Annual drugs sales were extracted from the French national authority's consumption database and from the IMS-MIDAS and national databases for European countries. RESULTS: The use of mild opioids in France decreased by 53% during the last 10 years due to the declining use of dextropropoxyphene combinations, along with an increase in the use of non-opioids and strong opioids (from 72 to 93 and 2 to 2...

Paracetamol [N-(4-hydroxyphenyl)acetamide, C8 H9 NO2 ] has several polymorphs, just like many other drugs. The most stable polymorphs, denoted Forms I and II, can be obtained easily and their crystal structures are known. Crystals of the orthorhombic, less stable, room-temperature Form III are difficult to grow; they need a special recipe to crystallize and suffer from severe preferred orientation. A crystal structure model of Form III has been proposed and solved from a combination of structure prediction and powder X-ray diffraction (PXRD) [Perrin et al...

Paracetamol is a common antipyretic often used to treat children with fever and pain. With the increasing administration of intravenous (IV) paracetamol, there will be the associated risk of medication dosing errors. We report a case of IV paracetamol overdose in a child with fever during hospital admission. A IV paracetamol dosing error occurred, with delayed recognition resulting in transient hepatotoxicity, with a peak alanine transaminase of 1946 IU/L and aspartate transaminase of 1633 IU/L.
