Drug tampering practices, with the aim to increase availability of drug delivery and/or enhance drug effects, are accessible on Internet and are practiced by some portion of recreational drug users. Not rarely, recreational misuse may result in toxic and even fatal results. The aim of the present study was to assess the tampering risk of medicaments containing different formulations of an opioid in combination with paracetamol or dexketoprofen, following the procedures reported in dedicated forums on the web...

Fluoride is a common stabilizing agent in forensic toxicology to avoid the frequent problem of degradation of drugs in blood samples especially described for cocaine. In cases only samples with addition of fluoride are available, it is a crucial question if also concentrations of common drugs other than cocaine (amphetamines, opiates and cannabinoids) are affected by fluoride. So far, there are only rare literature data available on discrepant results especially for Δ 9 -tetrahydrocannabinol (THC). In this study, comparative analysis of positive tested paired routine plasma/serum samples (n = 375), collected at the same time point (one device with and one without fluoride), was carried out with special focus on cannabinoids...

Hair can serve as a specimen for identifying past drug exposure. Segmental hair analysis may differentiate a single exposure from chronic use. Consequently, segmental hair analysis is useful for disclosing a single drug ingestion, as well as for determining repeated exposures in drug-facilitated crimes (DFCs). This paper presents an overview of toxicological investigations that have used hair analysis in DFC cases from 2009 to 2016 in Denmark. Hair concentrations were determined for 24 DFC-related drugs and metabolites, including benzodiazepines and other hypnotics, antihistamines, opioid analgesics, antipsychotics, barbiturates, and illicit drugs from DFC cases...

Diversion of prescription drugs is difficult to assess in quality and quantity. This study aimed to characterize diversion of prescription drugs in France through a comparative analysis of falsified prescriptions collected during three periods from 2001 to 2012. The data recorded in a national program which records all falsified prescriptions presented to community pharmacies were studied. Included data regarded: subjects, prescription forms and drugs. Description of the dataset in 3 periods (2001-2004, 2005-2008, and 2009-2012) was completed with clustering analyses to characterize profiles of prescriptions and subjects associated with the most reported drugs...

Benzylisoquinoline alkaloids (BIAs) are important secondary plant metabolites and include medicinally relevant drugs, such as morphine or codeine. As the de novo synthesis of BIA backbones is (still) unfeasible, to date the opium poppy plant Papaver somniferum L. represents the main source of BIAs. The formation of BIAs is induced in poppy plants by stress conditions, such as wounding or salt treatment; however, the details about regulatory processes controlling BIA formation in opium poppy are not well studied...

In some forensic autopsies blood is not available, and other matrices are sampled for toxicological analysis. The aims of the present study were to examine whether heroin metabolites can be detected in different post-mortem matrices, and investigate whether analyses in other matrices can give useful information about concentrations in peripheral blood. Effects of ethanol on the metabolism and distribution of heroin metabolites were also investigated. We included 45 forensic autopsies where morphine was detected in peripheral blood, concomitantly with 6-acetylmorphine (6-AM) detected in any matrix...

A high activity of cytochrome P450 2D6 (CYP2D6) reportedly leads toxicity of dihydrocodeine/codeine by increasing toxic potential of their metabolite dihydromorphine/morphine, which are further metabolized to highly active dihydromorphine 6-O-glucuronide and the less active morphine 3-O-glucorinide but rapidly excreted into urine as water-soluble forms. A case of acute respiratory depression after administration of prescribed dihydrocodeine phosphate (2.0 mg/day divided TID for 2 days) to a 1-month-old baby boy genotyped as cytochrome CYP2D6*1/*10-*36 is described...

Palmitoyl ethanol amide (PEA) is an endogenous substance that plays a role in neuropathic pain. In this article, we evaluated both the safety and the efficacy of ultramicronized PEA (um-PEA) in the treatment of low back pain related to nonsurgical lumbar radiculopathy. In this prospective single-blind study, patients with low back pain related to nonsurgical lumbar radiculopathy received the fixed combination acetaminophen/codeine (500 mg + 30 mg/d) for 7 days, and then it was stopped and changed to um-PEA (1200 mg/d) for 30 days...

OBJECTIVE: Recently, there has been great interest in the use, abuse and over-prescribing of opioid analgesics for children. However, there is a paucity of evidence on patterns of prescribing of both narcotic and non-narcotic analgesics for children by dentists. METHODS: We used a population-wide prescription drug database (PharmaNet) in British Columbia, Canada, to examine prescribing and dispensing of analgesics surrounding dental procedures. We examined all drugs prescribed for children by dentists between 1997 and 2013, as we had access to data on drug doses and days of medication supply...

Desymmetrization of a p-quinone monoacetal by organocatalytic sulfa-Michael addition provided rapid access to a C-ring building block for a formal synthesis of (-)-codeine. By means of a diastereoselective 1,2-addition for A/C-ring union, an intramolecular nitrone cycloaddition for construction of the phenanthrene core, and a sulfoxide elimination, an enantiopure key intermediate of the authors' previous synthesis of racemic codeine was available in 12 steps from isovanillin.

Background: Health professionals may advise women to either stop breastfeeding or drug treatment due to restrictive advice in drug monographs. Regional medicines information and pharmacovigilance centres in Norway (RELIS) provide free and industry-independent answers to questions about drugs and breastfeeding documented in a full-text, searchable database (RELIS database). We used the RELIS database to describe which health care practitioners sought information about medication safety in lactation, most common drugs involved, advice provided and which resources were used to provide the advice...

Keratinous matrices - hair and nails - accumulate substances over time and allow retrospective investigation of past consumption. Analysis of these matrices can provide information complementary to blood and urine analysis or can be used as standalone. So far, research has primarily focused on the detection of substances in hair, while studies in nails are scarce. In this study, we assessed concentrations of drugs of abuse and their metabolites in hair, finger- and toenails collected from the same individuals to evaluate differences and correlations between matrices...

Restless legs syndrome (RLS) is a distinct disorder, differing from chronic pain in many ways. Refractory RLS is characterized by unresponsiveness to dopamine agonists or alpha-2-delta ligands due to inadequate efficacy, augmentation, or adverse effects. This may result in severely impaired quality of life, profound insomnia, and suicidal depression. Opioid therapy is a mainstay in the management of these patients. This article summarizes the basic science and clinical evidence in support of their use, including the positive result of a large controlled multicenter study of 306 subjects, and outlines an approach to their use in clinical practice...

Toxicological investigations are often required by clinicians in comatose patients with suspected poisoning. However, the usefulness of toxicological analyses to support a diagnosis of acute poisoning is debated among clinicians and the interpretation of laboratory tests is challenging given the wide diversity of analytical techniques available. We report the case of an 8-year-old boy who was admitted to an intensive care unit with severe respiratory depression and neurological impairment. In order to formulate appropriate hypothesizes about the diagnosis and circumstances of intoxication, clinicians consulted toxicologists for a comprehensive toxicological screening...
