¡Sorpresa! El Viagra tiene un efecto protector para el corazón en casos de cáncer

En un estudio hecho con ratones se ha detectado que la combinación del principio activo del Viagra con otro medicamento utilizado para evitar los rechazos en un trasplante, puede ayudar a proteger el corazón contra los efectos tóxicos de algunas quimioterapias usadas en el tratamiento del cáncer. Descubre más detalles sobre este novedoso hallazgo.

Unos científicos de la Universidad de Virginia Commonwealth, en Estados Unidos, han descubierto que una curiosa combinación de medicamentos podría ayudar a prevenir la toxicidad de algunas quimioterapias que pueden afectar al corazón.

Según han presentado los científicos en el congreso anual de la Asociación Americana de Cardiología (AHA), que este año se realizó a principios de noviembre en Los Ángeles, la combinación del principio activo del Viagra (denominado sildenafilo) con rapamicina, un fármaco tradicionalmente empleado para evitar el rechazo de un trasplante, podría proteger el corazón de los pacientes con cáncer.

Al mismo tiempo, esta combinación de medicamentos podría reforzar la acción antitumoral de una medicina que se usa para combatir ciertos tipos de cáncer denominada doxorubicina (Adriamicina), cuya administración durante los últimos años ha disminuido, justamente debido a sus efectos tóxicos contra el corazón.

Para llegar a estos prometedores resultados, los investigadores hicieron pruebas en ratones. Por eso también advierten que todavía es muy pronto para determinar si es una solución efectiva. Todavía es necesario que se sumen nuevos estudios y que la combinación sea comprobada en humanos.

Lo que sí se ha probado en pacientes con cáncer, en este caso de la próstata, fue un posible efecto del Viagra para disminuir los efectos de la quimioterapia sobre la disfunción eréctil. En este caso, se trata de una investigación que fue presentada en la reunión anual de la Sociedad Americana de Radio-oncología (American Society for Radiation Oncology, ASTRO).

Allí, los investigadores del Centro Oncológico Conmemorativo Sloan-Kettering de Nueva York, en Estados Unidos, anunciaron que tras evaluar a pacientes con cáncer de próstata que no se había propagado, y que se sometieron a la radioterapia de haz externo y/o a la implantación de “semillas” radioactivas permanentes, que quienes habían tomado Viagra antes y después de la radioterapia tuvieron un mejor funcionamiento o desempeño sexual.

En cuanto a los efectos del Viagra sobre la salud del corazón, hay varias advertencias para los hombres que quieran usar este medicamento, ya que puede ser peligroso en algunos hombres que tengan o puedan tener problemas cardíacos.

Ten en cuenta que el Viagra como producto contra la disfunción eréctil fue descubierto por casualidad, mientras los científicos probaban su principio activo, el citrato de sildenafilo, para tratar la angina de pecho.

No debes tomar Viagra (ni otros productos similares, como Cialis ni Levitra) para solucionar tus problemas de erección, si:

Por estas razones, es importante que consultes con tu médico antes de usar este tipo de medicamentos para el tratamiento de la disfunción eréctil, ya que al igual que otras medicinas, pueden tener efectos no deseados (y hasta tener el resultado opuesto, cuando se usan como entretenimiento, generalmente por hombres jóvenes que, realmente, no las necesitan).

Y mientras la ciencia sigue buscando nuevas y mejores formas para combatir el cáncer, recuerda que mantener un estilo de vida saludable no sólo puede ayudarte a prevenirlo sino también a mantener tus niveles hormonales en línea y disfrutar de tu intimidad sexual, independientemente del paso del tiempo y de tu edad.
