商品名：Lutalyse, Prostin F2 alpha, ProstaMate, Prostaglandin
Dinoprost is a prostaglandin (PGF2 alpha) that induces luteolysis. Prostaglandin F2 and its analogs have a direct luteolytic action on the corpus leuteum. After injection, it will produce a functional regression of the corpus luteum (Luteolysis). In nonpregnant cycling cattle, this effect will result in starting estrus 2 to 5 days after injection. In pregnant animals, it will terminate pregnancy. In animals with prolonged luteal activity that have pyometra, mummified fetus, or luteal cysts, the luteolysis usually results in resolution of the problem and return to normal cycling.
Dinoprost is used for estrus synchronization in cattle and horses by causing luteolysis. In horses and cattle it is used to control timing of estrus in estrus-cycling females and in clinically anestrus females that have a corpus luteum. In pigs, dinoprost is used to induce parturition when given within 3 days of farrowing. In dogs, dinoprost has been used to treat open pyometra. In cattle, dinoprost has been used for treatment of chronic endometritis. In large animals, dinoprost is used to induce abortion in the first 100 days of gestation, but use for inducing abortion in small animals has been questioned.
