Sorry, Pat, I think maybe I can shed a little more light. Radiochemicals are used in medicine for two major reasons:
( 1 ) imaging and ( 2 ) cytotoxicity. In both applications of radiochemicals, the three dimensional characteristics of the compound used will determine its pharmacokinetics, that is, how it is absorbed into the body, distributed among tissues, metabolized and excreted. With some chemicals, the selectivity for a certain tissue is very high, so that if a radioactive version of that chemical is given, it may gather in high concentrations in one particular tissue, resulting in either or both ( 1 ) ability to image that tissue, or ( 2 ) cell death or damage in that tissue. Radiopharmaceuticals are not competitive with Nortran's Nociblockers (selective nociceptor blockers).Nociblockers work like traditional drugs, a drugs, they do not act by selectiveltly damaging tissue. If you are interested further, you would need to ask Cytogen for further scientific or medical information on their products. |
