Rome, February 14 - Medical researchers at Rome's La Sapienza university announced a pilot test in which sildenafil, a drug better known with its commercial name Viagra, is used to help treat heart problems in women with diabetes. The trials, the first of their kind to be carried out on women, follow the positive results of trials on men, which were recently published in the journal Circulation. After having demonstrated the effects of the drug on the hearts of men whose cardiovascular functionality was damaged by diabetes, La Sapienza researchers - in collaboration the University of Sassari and Italian pharmaceutical company Menarini's Fondazione Internazionale Menarini research institute - decided to test the drug's efficacy on women. The pilot scheme will be carried out with the participation of 40 diabetic women who have heart problems and are being treated at La Sapienza. Results are expected "within the year," said Andrea Lenzi, the head of La Sapienza's physiopathology department. Lenzi said the trials seek to "identify differences and similarities between the genders".
