background: age-related differences in the ethoxyresorufin o-deethylase (erod) activity of cyp1a1 and its inducibility in rats may determine the toxic potential of acetaminophen.  this study was carried out to compare the effects of acetaminophen (apap) and β-naphthoflavone (βnf) on cyp1a1 activity in young and adult rats. methods: for this purpose, young and adult rats (n = four / group) were...

P ublic health interventions are usually implemented without any attempt to prospectively evaluate them with an experimental research design. Thus the only way to evaluate the outcome of the intervention is to describe what happened before and after its implementation. In a new study published in PLoS Medicine, Morgan et al. have examined the change in deaths attributed to paracetamol (acetamin...

INTRODUCTION Until now, studies on paracetamol given intravenously have mainly been performed with the pro-drug propacetamol or with paracetamol in preterm babies above 32 weeks of gestation. Studies in these babies indicate that intravenous paracetamol is tolerated well, however studies on the efficacy of intravenous paracetamol are lacking. There are no pharmacokinetic data on the administrat...

a simple, sensitive, accurate and precise simultaneous uv spectrophotometric method has been developed for the estimation of carisoprodol, paracetamol and caffeine in tablet dosage form. the absorption maxima of the drugs were found to be 221, 248 and 273 nm for carisoprodol, paracetamol and caffeine respectively, in methanol, using a double beam uv/visible spectrophotometer. carisoprodol, para...

Aspirin and paracetamol consumption have been compared in 346 matched pairs of patients with haematemesis and melaena, and control individuals in the general community. Both aspirin and paracetamol intake were more common in patients than in controls, but the association for aspirin was stronger and was apparent with both recent and habitual intake, whereas for paracetamol the association was n...

Paracetamol is arguably the most commonly used analgesic and antipyretic drug worldwide, however its mechanism of action is still not fully established. It has been shown to exert effects through multiple pathways, some actions suggested to be mediated via N-arachidonoylphenolamine (AM404). AM404, formed through conjugation of paracetamol-derived p-aminophenol with arachidonic acid in the brain...

Purpose: To use differential scanning calorimetry (DSC) to predict the liquefaction time and dissolution profile of some commercial paracetamol suppositories as well as paracetamol suppositories formulated with palm oil base. Methods: The suppository base was prepared by mixing hydrogenated palm oil and palm kernel stearin in a ratio of 8:2. Three commercial paracetamol suppositories (A, B, and...

OBJECTIVES To compare the acceptability and effects on temperature of advice to unwrap children and give paracetamol or warm sponging treatments in the management of feverish illness at home. DESIGN A randomised, open, parallel group study using factorial design comparison of unwrapping, warm sponging plus unwrapping, paracetamol plus unwrapping, and paracetamol and warm sponging plus unwrapp...

BACKGROUND Efficient pain management is one of the most important components of care in the field of emergency medicine. OBJECTIVES This study was conducted to compare intravenous paracetamol and intravenous morphine sulfate for acute pain reduction in patients with limb trauma. PATIENTS AND METHODS In a randomized double-blinded clinical trial, all patients (aged 18 years and older) with a...

BACKGROUND Observational studies have reported an association between maternal use of paracetamol in pregnancy and childhood asthma, which was not explained by measured confounding factors. However, it is possible that this relation might be confounded by unmeasured behavioural factors linked to paracetamol usage; if that were the case, effects of similar magnitude of partner's paracetamol use ...
