The court stated Pfizer, based in New York, broke that bargain. The Supreme Court of Canada is invalidating Pfizer's patent on the popular erectile-dysfunction drug Viagra for failing to openly disclose the drug's lively ingredient, as required by Canadian intellectual property regulation.

Nonetheless, the researchers say the correlation proven here - along with other indicators in the research - is enough to identify sildenafil as a promising candidate drug for Alzheimer's illness, the viability of which will be explored in future randomized clinical trials designed to check whether or not causality does certainly exist.
