Resumen
En este trabajo se presenta el estudio químico, radiofarmacológico y el uso en seres humanos realizado con el “mebrofenin-Tc-99m”. La finalidad del trabajo fue determinar el uso potencial de este radiofármaco en seres humanos portadores de distintas entidades clínico patológicas. Para esto, se sintetizó el producto mejorando el rendimiento de reacción, mediante una modificación en la segunda etapa del camino de síntesis, lo que condujo a elevarlo del 70 al 90 %. Se determinó la cinética plasmática mediante la circulación extracorpórea realizada en ratas wistar, mientras que la hepática y renal se llevó a cabo en ratones endocriados. Todos los resultados fueron analizados mediante un procesador, obteniéndose las vidas medias plasmáticas y los máximos tiempos de captación.
The Chemical and radiopharmacological studies carried out with “mebro-fenin-Tc 99m“ and its use in human beings is presented. The purpose of this work was to determine ihe potential use of this radiopharmaceutical in humans, carriers of different clinic and pathological diseases. “Mebrofenin-lb 99mc” was synthesized by the method of Callery modified (in its second stage) so as to raise the yield from 70 % to 90 %. Plasma kinetics was determined by extracorporal circulation in wistar rats and hepatic and renal circulation were determined in all the results were analizad in a processor and thus plasmatic half Uves and maximun uptake times were obtained.
