Pharmacological properties

4.1 ATCvet code: QG03GA90

4.2 Pharmacodynamics

Follicle Stimulating Hormone from an extract of porcine pituitary glands for use in cattle.

FSH is the initiator of ovarian activity since it directly promotes growth of ovarian follicles. The administration of exogenous FSH to mammals at the time of follicular wave emergence stimulates growth of all follicles over 1.7 mm diameter which would normally be lost to atresia during each oestrus cycle. Multiple growing follicles require FSH stimulation until they are mature enough to respond to LH for the final stages of maturation and ovulation. This usually takes a period of approximately 4 days. In cattle, fertilised ova produced by superovulation with FSH, PMSG and other pharmacological agents containing high concentrations of LH have shown reduced fertilisation. The productcontains porcine pituitary extract with FSH activity and low LH activity.

4.3 Pharmacokinetics

When administered by intramuscular injection, FSH of porcine origin is rapidly absorbed from the site of injection. It has a half-life of 5 hours and FSH cannot be detected in the blood stream 12 hours after injection. FSH is inactivated by the liver and then excreted by the kidneys.

3

Target species

Cattle (reproductively mature females).

3

Indications

To induce superovulation in reproductively mature heifers or cows.

3

Dosage

For intramuscular administration only.

Dissolve each vial of freeze-dried product with the enclosed solvent. Reconstitution and subsequent withdrawal of product should be performed using strict aseptic technique.

Regimen:

Start injections on day 8 to 10 following observed or induced oestrus. Administer 2.5 ml (87.5 I.U.) of the product intramuscularly, twice daily, for 4 days. In conjunction with the 6th dose of the product, administer prostaglandin F2α or a prostaglandin F2α analogue, at their manufacturer's recommended dose, to cause luteolysis.

Inseminate animals at 12 and 24 hours after the onset of oestrus or 60 and 72 hours after prostaglandin treatment. Additional inseminations may be conducted at 12 hour intervals if indicated.

3

Contraindications

Do not use in cases of hypersensitivity to the active substance or to any of the excipients. Do not use in males and reproductively immature female cattle.

Do not use in pregnant cattle.

3

Adverse reactions

Target species: cattle (reproductively mature females).

* Following administration for three superovulation cycles, but did not prevent pregnancy

** Following superovulation a delayed return to heat is possible

Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See the package leaflet for respective contact details.

Warnings

Special precautions for safe use in the target species:

The product should only be used in clinically healthy cows and mature heifers, which are cycling normally. There is a wide range in response to superovulation between animals. There may be a small proportion of non-responders in any group treated.

Collection of embryo is normally started on day 7 following observed oestrus or first breeding. Prior to breeding and the collection of fertilized embryo from these animals, oestrus will have to be induced with prostaglandin F2α or a prostaglandin F2α analogue.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

Care should be taken when handling the product to avoid self-injection. Accidental self-injection of FSH may cause biological effects in women and to the unborn child. In case of accidental self- injection in women who are pregnant, or whose pregnancy status is unknown, seek medical advice immediately and show the package leaflet or the label to the physician.
