A review of benorylate - a new antirheumatic drug

Scandinavian Journal of Rheumatology. Supplement

Benorylate (Benoral, Benortan) is the esterification product of paracetamol and acetylsalicylic acid. It has anti-inflammatory, analgesic and antipyretic properties. Benorylate is probably absorbed as the intact molecule which accounts for its good gastric tolerance. After absorption, benorylate is hydrolysed into its components, salicylate and paracetamol, which then follows the usual routes of metabolism. Benorylate per se is also found in inflamed tissue and several studies, both in vivo and in vitro, have shown that it probably has an anti-inflammatory action of its own. Pharmacokinetic studies have shown that a twice daily administration of benorylate should be sufficient for a therapeutic effect and this has been confirmed by its use in patients. Clinical studies have compared benorylate with aspirin, indomethacin, ibuprofen and phenylbutazone and have shown its value in rheumatoid arthritis, osteoarthrosis and other musculoskeletal conditions. The overall tolerance is excellent. Some minor gastric disturbances are reported from time to time, but these are less than with comparable doses of aspirin. Studies measuring occult blood loss in the stools have shown that this is not a significant problem with benorylate and that...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.


Incretins are metabolic hormones that stimulate a decrease in glucose levels in the blood and they have been implicated in glycemic regulation in the remission phase of type 1 diabetes. Here is the latest research.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.
