Gadolinium is an element. Elements cannot normally be patented. http://www.webelements.com/webelements/elements/text/Gd/key.html In addition to Magnevist and Prohance, Dotarem and Omniscan are two other Gd-based contrast media. http://www.mr-tip.com/serv1.php?type=db1&dbs=dotarem http://www.mr-tip.com/serv1.php?type=db1&dbs=omniscan |

Sorry if I was not clear. My question is in regards to when the MRI contrast agent, called gadolinium generically and Magnevist (Gadopentetate Dimeglumine) or Prohance (gadoteridol) by Brand name come off patent and when will generic versions of these compounds be made available. Here are some links with more information: http://www.berlex.com/html/products/pi/Magnevist_PI.pdf http://www.berleximaging.com/magnevist/product_info.html;jsessionid=9A0FA9F2747BFF7FA2CD918B0CEF57D3 http://www.amershamhealth.com/medcyclopaedia/medical/volume%20i/mr%20contrast%20medium.asp http://www.bracco.com/Bracco/Internet/Imaging/MRI/# |

I came across this web site too. It is not really clear as to when the compound will come off patent. I searched the US Patent Office web site without much success although the Canadian patent office indicated that it came off patent there earlier this year. More specific information is required. Thanks for looking. |
