The Nordimet (methotrexate) prefilled injector pen is indicated for the treatment of active rheumatoid arthritis and a number of other autoimmune conditions including severe psoriatic arthritis.
Patients activate the auto-injector simply by pressing the device directly onto their skin.
The button-free mechanism is intended to enable patients with painful joints or poor manual dexterity to administer their methotrexate injections independently.
"I feel that a button-free delivery device like Nordimet will enable nurses to teach many more patients to confidently self-administer their methotrexate injection once a week at home," said Louise Parker, Clinical Nurse Specialist in Rheumatology.
The device also audibly clicks and vibrates at the start and end of the injection, reassuring patients of the injection’s successful completion.
In a study of 149 nurses, 87% found the device easy to operate, and 86% stated that their patients would find the button-free mechanism easier to use than a button-activated device.
Professor Peter Taylor, Norman Collison Professor of musculoskeletal sciences at the University of Oxford and the Head of Clinical Sciences at the Botnar Research Centre, called the new auto-injector "a most welcome addition to treatment choice for patients."
Nordimet is available in eight dose presentations ranging from 7.5mg to 25mg.
