Composition

Each ml contains 17-β estradiol benzoate 5 mg, Vitamin A 12,500 I.U., Vitamin E 5 mg.

Pharmacology

Estradiol can promote the normal growth and development of female organs and parasexual characteristics of female animals. Causes enlargement and secretion of cervical mucosal cells, thickening of the vaginal mucosa, promotes endometrial hyperplasia and increases uterine smooth muscle tone. Estradiol also has an effect on the skeletal system, can increase bone calcium salt deposition, accelerate epiphyseal closure and bone formation, and has the effect of moderately promoting protein synthesis, as well as increasing water and sodium retention. In addition, estradiol negatively regulates the release of gonadotropins from the anterior lobe of the pituitary gland, thereby inhibiting lactation, ovulation, and the secretion of male hormones.

Indications

Sex hormone drugs. It is used for aphrodisiacs of animals with inconspicuous estrus and the discharge of fetal membranes, mummified or dead fetuses.

Horses: 10~20 mg (2~4 ml) per time.

Adverse reactions

(1) In small animals such as dogs, it can cause blood cachexia, which is mostly seen in elderly animals or when applied in large doses. At first, platelets and leukocytosis are increased, but gradually develop into a decrease in platelets and white blood cells. In severe cases it may cause aplastic anemia.

(2) It can cause cystic endometrial hyperplasia and pyometra.

(3) It may prolong the estrus period of cattle and reduce lactation. Precocious puberty and follicular cysts may occur after treatment. The above effects are mostly caused by overdosage, and dose adjustment can reduce or eliminate these adverse reactions.
