Zwitterionic codeine-derived methacrylate monoliths for enantioselective capillary electrochromatography of chiral acids and chiral bases
2018
Thiol-ene click reaction of N-acetyl-L-cysteine methyl ester to codeine, followed by reaction with allyl isocyanate and hydrolysis to the corresponding zwitterionic chiral selector and its subsequent bonding to the surface of a methacrylate monolith provided a new chiral capillary column for enantiomer separation of chiral acids and chiral bases. First, the epoxy groups of a poly(glycidyl methacrylate-co-ethylene dimethacrylate) monolith were converted into amine residues, followed by reaction with allylglycidyl ether. In this way, a spacer arm was bonded to the surface before coating and cross-linking poly(3-mercaptopropyl methylsiloxane) (PMPMS) via radical addition (thiol-ene click react…
Drug safety related to agents used for opioid maintenance therapy
2017
IntroductionThere is only little data regarding drug safety related to agents used for opioid maintenance therapy (OMT).Objectives/aimsTo study drug safety and the reporting behaviour of adverse drug reactions (ADR) related to OMT.MethodsA cross-sectional questionnaire-based telephone survey among physicians providing outpatient OMT in a federal state of Germany (n = 176; response rate = 55.7%) was conducted.ResultsMost of the respondents (n = 97/55.1%) reported that they observe ADR related to buprenorphine, [dihydro]codein and [levo]methdone rarely (n = 38/21.6%), very rarely (n = 39/22.2%) or never (n = 20/11.4%). Methadone was reported to be most frequently associated with the occurrenc…
Impact of a physician-targeted letter on opioid prescribing.
2020
We study the effect of a physician-targeted nudge letter on opioid prescribing. In May 2017, the Social Insurance Institution of Finland sent a personal information letter to all physicians who had issued a prescription containing at least 100 tablets of paracetamol-codeine combination to a new patient. The aim of the letter was to draw the physicians’ attention to their prescribing practices and to decrease the size of the first codeine prescription. Using individual level register data and a difference-in-differences strategy, we estimate that the letter decreased the average number of tablets purchased by new patients by 12.5 percent and the probability of a first purchase being at least…
Determinants of Prescription Opioid Use : Population‐Based Evidence from Finland
2021
Background and aims Previous studies have shown that prescription opioid use is more common in the socioeconomically disadvantaged communities in the US. This study examined the area and individual‐level determinants of prescription opioid use in Finland during the period 1995‐2016. Design Logistic regression analysis using nationwide data on filled opioid‐related prescriptions dispensed at Finnish pharmacies and covered by the National Health Insurance. Opioid consumption was linked, using personal identification codes, to population‐based data maintained by Statistics Finland, which records individual background and area‐level characteristics. Setting and participants Working‐age populati…
