It is a synthetic steroid used in early first term abortions. Typically, termination of intrauterine pregnancies of up to 49 days gestation but up to 63 days in the UK and Sweden. More importantly...its half-life is approximately 18 hours and its excretion is predominately fecal (83%). So as we've discussed under a hypothetical "Abortion Prohibition" if the Womb Gestapo can't get their court order to draw blood from a "fetal homicide suspect" within a day, or actually less than a day.....they'll have to go down in the sewers and try to find her poop and do a DNA match. BTW, for the "Israel Right or Wrong" Neo-cons....or "Christian Zionists/Rapture Ready" types? The drug was approved in Israel in 1999.
