4. CLINICAL PARTICULARS


4.1 Target species


Cattle (heifers, cows) and pigs (sows)


4.2 Indications for use, specifying the target species


Cattle (heifers, cows):


To schedule the time of oestrous and ovulation and for cycle synchronization in animals with an ovulatory cycle when applied during the diestrus (induction of oestrus in non-detected oestrus, synchronisation of oestrus)

Anoestrus and uterine disorders caused by a progesterone-induced oestrous cycle blockade (induction of oestrous in anoestrus, endometritis, pyometra, corpus luteal cysts, follicular luteal cysts, shortening of the sexual rest period)


Pigs (sows):

Induction or synchronisation of farrowing from day 114 of pregnancy onwards (day 1 of pregnancy is the last day of insemination).


4.3 Contraindications


Do not use for intravenous administration

Do not use in pregnant animals where the induction of abortion or parturition is not intended

Do not use in case of spastic diseases of the respiratory tract and gastrointestinal tract.

4.4 Special warnings for each target species


None


4.5 Special precautions for use


Special precautions for use in animals


To reduce the risk of anaerobic infections care should be taken to avoid injection through contaminated areas of skin. Clean and disinfect injection sites thoroughly before application.


Pigs:

Use only if the cover dates are known. Too early an administration could adversely affect the viability of the piglets. This is the case when the injection is given more than 2 days before the average gestation period of the stock. Day 1 of pregnancy is the last day of insemination. The gestation period is generally 111-119 days.


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



4.6 Adverse reactions (frequency and seriousness)


Anaerobic infections may occur if anaerobic bacteria are introduced into the tissue by the injection, in particular following intramuscular injection.


Cattle:

When used for induction of parturition, the incidence of retained placenta may be increased depending on the time of treatment. In very rare cases, anaphylactic-type reactions can be observed which might be life threatening and require rapid medical care.


Pigs:

The abnormal behaviour that might occur in pigs immediately after treatment, when the drug has been used to induce parturition, is similar to that of sows before normal birth and normally subsides within one hour.


4.7 Use during pregnancy, lactation or lay


Do not use in pregnant animals when abortion or induction of parturition is not intended.

Safety of the product has not been established during lactation.


4.8 Interaction with other medicinal products and other forms of interaction


Concurrent use of oxytocin and Cloprostenol increases the effects on the uterus.


4.9 Amounts to be administered and administration route


For intramuscular injection in cattle (heifers, cows).

For deep intramuscular injection in pigs (sows) (with a needle at least 4 cm long).


Cattle (heifers, cows): 0.5 mg Cloprostenol/animal corresponding to 2.0 ml PGF Veyx forte/animal


In order to synchronise oestrus in a cattle herd, it is recommended that the product is administered on two occasions with an 11-day interval between treatments.


Pigs (sows): 0.175 mg Cloprostenol/animal corresponding to 0.7 ml PGF Veyx forte/animal

Use automatic syringe equipment for the 50 ml vials.


Single administration.


The rubber stopper of the vial may be safely punctured up to 25 times. Otherwise, automatic syringe equipment, or a suitable draw-off needle, should be used for the 50 ml vials to avoid excessive puncturing of the closure.


4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary


In case of overdose the following symptoms may occur:

Increased heart rate, increased respiratory rate, bronchoconstriction, increased rectal temperature, increased defecation and urination, salivation, nausea and vomiting.

No antidotes are available.


4.11 Withdrawal period(s)


Cattle, pigs (meat and offal): 2 days

Cattle (milk): zero hours


5. PHARMACOLOGICAL PROPERTIES


5.1 Pharmacodynamic properties


Pharmacotherapeutic group: prostaglandin-F -agonist

ATCvet code: QG02AD90


Cloprostenol belongs to the group of prostaglandin-F-agonists, which exert a luteolytic effect dependent on species and time of treatment. Furthermore, this group of substances has a contractile effect on the smooth muscles (uterus, gastro-intestinal tract, respiratory tract, vascular system).

Treatment during diestrus or in the case of persistent corpus luteum causes luteolysis. The associated removal of the negative feed-back mechanism induced by progesterone leads in animals with cyclic ovarian function to a premature onset of heat and ovulation.

Cloprostenol produces a 200- to 400-fold luteolytic effect compared to prostaglandin-F; however, the effect on the smooth muscles appears to be equally strong.


5.2 Pharmacokinetic particulars


Peak plasma concentrations were observed within 15 minutes to 2 hours after intramuscular injection of Cloprostenol in cattle and pigs. The subsequent rapid elimination phase is characterised by a half-life from 1 to 3 hours, with a subsequent phase of slow elimination over a period of up to 48 hours, with a half-life of 28 hours.

Cloprostenol is distributed evenly throughout the tissues. Excretion via the faeces and urine is virtually equal. Less than 0.4% of the applied dose in cattle is eliminated via the milk. Maximum concentrations are measured approx. 4 hours post application.
