Pharmacological properties

4.1 ATCvet codes: QG03GA99 Gonadotropins, combinations

4.2 Pharmacodynamics

The veterinary medicinal product is a lyophilisate 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 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 synchronizes the first post weaning ovulation in 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 i.m. injection is high. In pigs the elimination half lives of PMSG and HCG were shown to be 36 and 27 hours respectively.
