Recently, the emergence of new psychoactive substances (NPS) has led to their wide use among clubbers and men who have sex with men (MSM) for their stimulant effects. However, their use in drug facilitated sexual assault (DFSA) has rarely been described. Herein we report a case of a 44 years-old man who was assaulted after a party. Due to late reporting of the offense, only hair (black) was sampled 15 days later and a segmental analysis was achieved to look for most DFSA agents and NPS. Twenty mg of each segment (A:0-1cm, B:1-3cm and C:3-5cm) were incubated in phosphate buffer pH 5...

The SeDeM Expert Diagram System (SeDeM EDS) was originally developed to provide information about the suitability of powders to produce direct compressible tablets. Multiple-unit pellet systems (MUPS) are dosage forms consisting of pellets compressed into tablets or loaded into hard gelatine capsules. The aim of this study was to apply the SeDeM EDS to different size pellets (i.e. 0.5, 1.0, 1.5, 2.0 and 2.5 mm) containing different APIs (i.e. doxylamine, ibuprofen or paracetamol) to determine which properties should be corrected to yield MUPS tablet formulations...

Hair analysis has been established as a prevalent tool for retrospective drug monitoring. In this study, different extraction solvents for the determination of drugs of abuse and pharmaceuticals in hair were evaluated for their efficiency. A pool of authentic hair from drug users was used for extraction experiments. Hair was pulverized and extracted in triplicate with seven different solvents in a one- or two-step extraction. Three one- (methanol, acetonitrile, and acetonitrile/water) and four two-step extractions (methanol two-fold, methanol and methanol/acetonitrile/formate buffer, methanol and methanol/formate buffer, and methanol and methanol/hydrochloric acid) were tested under accurately equal experimental conditions...

Nausea and vomiting of pregnancy (NVP) is the most prevalent medical condition during gestation, affecting up to 85% of pregnant women. Many of them hesitate to use medications due to perceived fetal risks. Areas covered: There are two main aspects to medication safety in NVP: The fetal safety of drugs used to treat NVP symptoms, and the risks of untreated NVP. While mild and moderate NVP are not associated with major increase in fetal or maternal risks, and may render protective fetal effects, they have major impact on the quality of life of the mother...

Background The unintentional misuse of over-the-counter sleep aids among older adults is an important public health problem and a focus of Healthy People 2020. Accordingly, the 2015 Beers Criteria for Potentially Inappropriate Medication Use in Older Adults recommends that individuals 65 years or older avoid use of diphenhydramine and doxylamine; however, many over-the-counter sleep products contain these active ingredients. Objective To identify the proportion of older adults using an over-the-counter medication containing diphenhydramine or doxylamine, and compare their characteristics with older adults using an over-the-counter medication that does not contain these ingredients...

Hyperemesis gravidarum (HG) is a severe and prolonged form of nausea and/or vomiting during pregnancy. HG affects 0.3-2% of pregnancies and is defined by dehydration, ketonuria, and more than 5% body weight loss. Initial pharmacologic treatment for HG includes a combination of doxylamine and pyridoxine. Additional interventions include ondansetron or dopamine antagonists such as metoclopramide or promethazine. The options are limited for women who are not adequately treated with these medications. We suggest that mirtazapine is a useful drug in this context and its efficacy has been described in case studies...

AIMS: Codeine containing analgesics are commonly taken in overdose, but the frequency of respiratory depression is unknown. We investigated whether paracetamol-codeine combination overdoses caused respiratory depression more than paracetamol alone. METHODS: We reviewed deliberate self-poisoning admissions with paracetamol (>2 g) and paracetamol-codeine combinations presenting to a tertiary toxicology unit (1987-2013). Demographic information, clinical effects, treatment (naloxone, length of stay [LOS], mechanical ventilation) were extracted from a prospective database...

BACKGROUND: Nausea and vomiting of pregnancy (NVP) affects up to 80% of expecting mothers. In April 2013 the FDA approved the delayed-release combination of doxylamine succinate and pyridoxine hydrochloride (Diclegis®) for NVP, based in part, on the results of a phase III randomized trial demonstrating the efficacy of this drug combination [study drug marketed under the trade name Diclectin® in Canada and Diclegis® in the United States] compared to placebo in pregnant women. Study drug dosing occurred for 14 days, which is substantially longer than what has been performed in similar studies...
