PHARMACOLOGICAL CLASS

Synthetic prostaglandin F₂α (PGF₂α) analogue.


INDICATIONS

NORFLOSTEN® is indicated for use in cattle, sheep, and goats for:

  • Synchronization of estrus

  • Treatment of luteal cysts

  • Induction of estrus

  • Termination of abnormal or unwanted pregnancy (within approved gestational limits)

  • Treatment of pyometra and chronic endometritis with functional corpus luteum

  • Induction of parturition (where indicated)


MECHANISM OF ACTION

Cloprostenol is a potent analogue of prostaglandin F₂α that induces luteolysis by causing regression of the corpus luteum. This results in a rapid decline in progesterone levels, leading to estrus or parturition depending on the reproductive status of the animal.

  • Cattle: 2 ml per animal (500 µg cloprostenol)
