Dinoprost (Prostaglandin F2α) API

Veterinary Prostaglandin for Labor Induction and Reproductive Management

Dinoprost, also known as Prostaglandin F2α (PGF2α), is a synthetic prostaglandin widely used in veterinary medicine for reproductive control. Identified by CAS Number: 551-11-1 and manufactured according to JP and in-house standards, Dinoprost is a well-established active pharmaceutical ingredient (API).

Dinoprost acts directly on the myometrium, stimulating uterine smooth muscle while softening and dilating the cervix contraction. These pharmacological effects make it suitable for inducing labor, terminating pregnancy, and managing specific reproductive conditions in livestock.

Mechanism of Action

Dinoprost mimics the activity of naturally occurring Prostaglandin F2α, a hormone involved in reproductive regulation. It works by:

Stimulating uterine smooth muscle contraction
Softening and dilating the cervix
Promoting luteolysis and uterine evacuation

These effects allow veterinarians to precisely manage labor induction and pregnancy termination in animals.

Applications in Veterinary Medicine

Dinoprost is widely used for reproductive management in livestock, including:

Cattle – Induction of labor, treatment of reproductive disorders, estrous cycle control
Horses – Termination of pregnancy, management of reproductive conditions

Dinoprost is commonly marketed under the trade name Lutalyse and is administered via injection as directed by a licensed veterinarian.
