In regards to Dr. Horacio Croxatto

USACH proposes CEDENNA researcher for National Science Prize 2010

August 9, 2010

Dr. Croxatto is responsible for the nano-biomedicine research line of the Center, which is working on developing methods of contrasting to obtain better medical images, as well as encapsulating antibiotics in nanoparticles, which would improve their effectiveness. The same principle is used for encapsulating pigments and antibiotics for poultry, pigs and salmon.

The Universidad de Santiago de Chile (USACH) officially proposes the researcher Dr. Horacio Croxatto, honorary professor of the Faculty of Medicine of the Universidad de Chile and Tenured Professor in the Faculty of Chemistry and Biology of the Universidad de Santiago de Chile, for the National Natural Science Prize 2010.

The University considered that the scientific work of Dr. Croxatto, one of the main researchers of CEDENNA, has earned him the highest award that our country can give to a scientist in the field of the natural sciences.

In a letter to the jury of the National Natural Sciences Prize that presented Dr. Croxatto as a candidate for the prize, the Rector of the Universidad de Santiago, Juan Manuel Zolezzi pointed out that Dr. Croxatto and his group have made very revealing contributions to our understanding of the physiology of lactancy and the clinical pharmacology of anti-progestin, and was the first in the world to demonstrate transdermic absorption of progestin in women in doses that inhibit ovulation.

The Rector added that based on Dr. Croxatto’s research with animal models, he developed the idea of combining silicon with progestin crystals, which has since been used in contraceptive pills.

Dr. Croxatto produced small devices that were implanted under the skin of the arms of women who had volunteered to test this potential contraceptive method. This simple idea worked and resulted in a pharmaceutical product that today is being used by millions of women around the world. He was never concerned with the economic potential of this invention, nor has he ever received any financial remuneration, affirmed the Rector of USACH in his letter.

Dr. Croxatto’s work on the mechanism of action of diverse contraceptive methods have been widely cited at the international level and he is consequently considered a world authority on the matter.

Dr. Croxatto is co-founder of the Chilean Institute of Reproductive Medicine (ICMER), a non-profit foundation dedicated to researching the variables that that affect reproduction and mother-infant health, in order to promote sexual and reproductive health among the poorest sectors and provide low cost medical care.

The jury of the National Natural Sciences Prize 2010 is composed of the Minister of Education, Joaquín Lavín; the Rector of the Universidad de Chile, Víctor Pérez; the last prize winner, Nibaldo Inostroza, the Rector of the Universidad Católica de Chile, Ignacio Sánchez and the representative of the Chilean Academy of Sciences of the Institute of Chile, Juan Alfonso Asenjo.
