Use of 15-keto-prostaglandin E or F compounds for uterine contractions.

摘要

A use of prostanoic acid derivative selected from a) 15-ketoprostaglandin E compounds, and b) 15-ketoprostaglandin F compounds with the proviso that when the only one group, which is unsubstituted n-pentyl group, is attached to the carbon atom at the 15-position of the prostanoic acid nucleus and the bond between the carbon atoms at 5- and 6-positions is a double bond, then the bond between the carbon atoms at 13- and 14-positions is a single bond. o
