a sensitive and selective method using combination of principal component analysis (pca), artificial neural network (ann) and uv-visible spectroscopy has been developed for the simultaneous determination of acetaminophen (amp) and codeine (cod) in plasma samples. the ann trained by the back-propagation learning was employed to model the complex non-linear relationship between the pcs extracted ...

AH-7921 is a synthetic μ-opioid agonist, approximately equipotent with morphine. We report the death of two young individuals after ingestion of AH-7921 in combination with other psychoactive drugs. In the first case a young man died shortly after ingesting Internet drugs. Toxicological analysis of post mortem peripheral blood revealed AH-7921 (0.43 mg/L), 2-FMA (0.0069 mg/L) and 3-MMC (0.0021 ...

Isoqinoline alkaloids constitute one distinct group of secondary metabolites of the Papaverace family. Codeine and thebaine are important alkaloids of Papaver bracteatum which use widely due to its medicinal properties. Therefore it is...

INTRODUCTION Consumption of codeine can lead to positive urine test for morphine in athletes. Morphine is classified as a prohibited doping drug while Codeine is not. Morphine/codeine ratio is used in forensic medicine to distinguish the consumption of codeine from abuse of morphine and other narcotics. CASE PRESENTATION We present an athlete with positive urine test for morphine with a histo...

The objective of this study was to quantify the analgesic efficacy of paracetamol and its combination with codeine or caffeine through a systematic overview and meta-analysis of relevant randomized controlled trials (RCTs). Systematic retrieval of relevant clinical trials was carried out using computerized searches, historical searches and communication with manufacturers. The results of RCTs w...

Prescribing of compound analgesics containing dextropropoxyphene was limited to consultants only in a teaching hospital. Inpatient prescribing (mainly by junior staff) fell immediately to very low levels but outpatient prescribing (by consultants) fell more slowly to about one-third of the original level, suggesting that patients and doctors find dextropropoxyphene compounds useful. Prescriptio...

This paper describes the application of Raman spectroscopy to the detection of exogenous substances in cyanoacrylate-fumed fingerprints. The scenario considered was that of an individual handling a substance and subsequently depositing a contaminated fingerprint. These fingerprints were enhanced by cyanoacrylate fuming, a process in which a layer of white cyanoacrylate polymer is deposited on t...
