Pharmacological properties

4.1 ATCvet code: QG03GA99.

4.2 Pharmacodynamics

The veterinary medicinal product is a freeze-dried presentation of hCG and PMSG in combination with solvent for reconstitution. The veterinary medicinal product contains 400 IU of PMSG and 200 IU of hCG. PMSG and hCG are two large glycoproteins composed of two non-covalently associated alpha and beta subunits. The extensive glycosylation of the CTP tail of the beta subunits of PMSG and hCG results in the extended half-life typical of both hormones which reaches, in pigs, 36 and 27 hours for hCG and PMSG respectively. PMSG displays dual FSH and LH activities. It therefore stimulates follicular growth and follicular maturation during the days preceding oestrus and ovulation. HCG displays only LH like activity. It therefore plays a key role in the induction of ovulation of the follicles stimulated to grow by PMSG. This explains why the veterinary medicinal product efficiently induces and synchronises puberty (gilts) and the first post weaning ovulation (sows).

4.3 Pharmacokinetics

After injection to pigs, PMSG and hCG are rapidly absorbed as, for both hormones, Cmax is reached within 8 hours for both hormones. Bioavailability following intramuscular injection is high. In pigs, the elimination half-lives of PMSG and hCG were shown to be 36 and 27 hours respectively.

Target species

Pigs.

Indications

For the promotion of a fertile oestrous cycle in gilts and in sows post-weaning and the treatment of suboestrus or anoestrus in barren sows due to hormonal imbalance.

3

Dosage

Reconstitution: Reconstitute by injecting approximately 2 ml of the solvent provided into the hormone vial, ensure the freeze-dried plug is fully dissolved, and re-inject the resulting solution into the solvent vial. Shake well before use. Reconstituted solution is colourless.

Intramuscular or subcutaneous use.

Sows and gilts: One dose (5 ml) of reconstituted veterinary medicinal product should be aseptically injected subcutaneously or preferably, intramuscularly, at the base of the ear using a 1.5" needle, which must be directed horizontally.

Gilts: Administration of a single dose of the veterinary medicinal product to gilts over the age of five months will normally result in a fertile oestrus within five days.

Sows post-weaning: To promote early post-partum oestrus (particularly where early weaning is practised) it is recommended that a single injection of the veterinary medicinal product is given within 48 hours of weaning.

Barren sows: Cases of suboestrus or anoestrus due to hormonal imbalance may respond favourably to a single dose of the veterinary medicinal product, exhibiting normal heat within five days of injection.

If corpora lutea are present on the ovary when the veterinary medicinal product is administered, the sow or gilt will fail to respond. For this reason, if an anoestrus sow or gilt fails to respond to the veterinary medicinal product, wait 10 days before repeating the injection.

Contraindications

Do not inject into the subcutaneous fat.
