Product Introduction

Dinoprost (CAS 551-11-1)

Properties, Uses, and Veterinary Applications

Dinoprost, also known as Prostaglandin F₂α (PGF₂α) , is a naturally occurring prostaglandin widely used in veterinary medicine for reproductive management. Known for its potent ability to induce uterine contractions and soften the cervix, Dinoprost plays a crucial role in inducing labor, terminating pregnancy, and treating reproductive disorders in livestock.

CAS Number: 551-11-1

Standards: JP, In-House Standard

What is Dinoprost?

Dinoprost (PGF₂α) is a hormone-like compound naturally produced in mammals and essential for reproductive regulating functions. As a pharmaceutical ingredient, it is used to replicate and enhance these physiological effects.

By acting directly on the myometrium (the muscular layer of the uterus), Dinoprost stimulates strong, coordinated uterine contractions and promotes cervical softening and dilation, making it effective for:

▸ Artificial abortion

▸ Late-term labor induction

▸ Treatment of reproductive disorders in animals

Applications of Dinoprost (PGF₂α)

Dinoprost is widely used across veterinary medicine-especially in livestock breeding and reproductive management. It is also commercially known as Lutalyse .

Inducing Labor in Cows

▸ Inducing labor at term

▸ Managing delayed partitions

▸ Resolving reproductive disorders

Pregnancy Termination in Horses

Used in equine medicine to terminate early pregnancy or manage reproductive complications requiring controlled uterine contraction.

Treating Reproductive Conditions

▸ Luteal cysts

▸ Pyometra

▸ Anestrus

▸ Post-calving complications

How It Works

Dinoprost functions as a synthetic equivalent of endogenous PGF₂α. It induces luteolysis and stimulates uterine contraction , allowing precise reproductive cycle control and improved herd fertility management.
