A medical trial of Viagra on pregnant moms in the Netherlands was stopped after the death of 11 babies, said today one of the participating hospitals.
And up to 15 women taking this medication face an agonizing expectation. When the trial in the Netherlands of Sildenafil – sold under the brand name Viagra – was stopped, about half of the 183 participating pregnant women were taking sildenafil, the academic medical center of the University of Amsterdam ( AMC)
The study – which began in 2015 and involved 11 hospitals – was designed to examine the potential benefits of an increase in blood flow to the placenta in mothers whose infants to be born were seriously underdeveloped. "Previous studies have shown that sildenafil would have a positive effect on the growth of babies.The initial results of the current study have shown that there can be adverse effects for the baby after birth."
But the results showed that 17 babies were born with lung conditions and 11 died.
In the approximately equal control group, however, among women taking sildenafil, 11 babies died due to a "possibly related lung disease" that caused high blood pressure in the lungs and which may be due to a reduction in oxygen levels.
An interim badysis revealed that the risk of blood vessel disease in the lungs "appears to be greater and the risk of death after birth seems to have increased. The researchers found no positive effect for the children on other findings, "said the CMA.
Stephen Evans, professor of pharmacoepidemiology at the School of Hygiene and Medicine London Tropical, said that the small number of trials with pregnant women "There have been other studies in this area, involving preliminary work using animals and using pregnant women, and nothing n & rsquo; Indicated that the treatment was dangerous based on previous research, "he said.
The drug was originally developed by Pfizer, but is now available as a generic Pfizer did not make any immediate comment.
