La FDA estadounidense ha autorizado la puesta en el mercado de un nuevo analgésico, la ziconotida, para tratar los dolores crónicos en personas que con otros tratamientos como la morfina no han obtenido el efecto deseado.
Este será el primer tratamiento analgésico de esta categoría aprobado en los últimos 20 años, explicó en un comunicado el grupo farmacéutico islandés Elan que comercializa este medicamento con el nombre de Prialt.
Este fármaco es un bloqueador selectivo de los canales nerviosos que transmiten los signos de dolor, señala el responsable de la investigación, Dr. Lars Ekman.
El tratamiento está destinado a personas que sufren dolores severos durante 6 meses y cuyas causas son múltiples, indicó el Dr. Ekman, que puso como ejemplo operaciones en la espalda que no hayan tenido éxito, heridas graves, cáncer, sida o problemas en el sistema nervioso.
