4. CLINICAL PARTICULARS
4.1 Target species
Cattle, horses and pigs.
4.2 Indications for use, specifying the target species
Cattle:
- induction of luteolysis allowing resumption of oestrus and ovulation in cyclic females when used during dioestrus
- synchronisation of oestrus (within 2 to 5 days) in groups of cyclic females treated simultaneously
- treatment of suboestrus and uterine disorders related to a functioning or persistent corpus luteum (endometritis, pyometra)
- treatment of ovarian luteal cysts
- induction of abortion until day 150 of pregnancy
- expulsion of mummified foetuses
- induction of parturition (within the last two weeks of gestation).
Horses:
- induction of luteolysis in mares with a functional corpus luteum.
Pigs:
- induction or synchronisation of farrowing (generally within 24 to 36 hours) from day 113 of pregnancy onwards (day 1 of pregnancy is the last day of natural or artificial insemination).
4.3 Contraindications
Do not use in case of hypersensitivity to the active substance or to any of the excipients.
Do not use in animals with spastic respiratory or gastro-intestinal diseases.
Do not use in pregnant animals, for which induction of abortion or parturition is not intended.
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, which might be related to the pharmacological properties of prostaglandins, care should be taken to avoid injection through contaminated areas of skin. Clean and disinfect injection sites thoroughly before application.
Avoid contamination of the product during use. Should any apparent growth or discoloration occur, the product should be discarded.
Pigs:use only when precise date of insemination is known. Administer on day 113 of gestation, at the
earliest. Genestran administered earlier, may impair the viability and weight of piglets.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Direct contact with skin or mucous membranes of the user should be avoided. Prostaglandins of the F2αtype may be absorbed through the skin and may cause bronchospasm or miscarriage. Care should be taken when handling the product to avoid self-injection or skin contact. Pregnant women, women of childbearing age, asthmatics and persons with other respiratory tract diseases should exercise caution when handling cloprostenol. Those persons should wear gloves during administration of the product. Accidental spillage on the skin should be washed immediately with soap and water. In case of accidental self-injection, seek medical advice immediately and show the package leaflet or the label to the physician.
4.6 Adverse reactions (frequency and seriousness)
Cattle:
Following induction of parturition with Genestran, an increased incidence of placental retention may be observed.
Horses:
After an injection of Genestran, slight sweating and diarrhoea may develop temporarily.
Pigs:
No undesirable effects have been reported.
4.7 Use during pregnancy, lactation or lay
Pregnancy:
Do not use in pregnant animals, for which induction of abortion or parturition is not intended.
Lactation:
Can be used during lactation.
4.8 Interaction with other medicinal products and other forms of interaction
None known.
4.9 Amounts to be administered and administration route
Cattle:
2.0 ml intramuscularly (150 μg).

Synchronisation of oestrus: animals are to be treated twice within 11 days.
Horses:
0.3- 0.5 ml intramuscularly (22.5 - 37.5 μg)
Intended for single use.
Pigs:
0.7- 1.0 ml intramuscularly (52.5 - 75 μg)

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

4.11 Withdrawal period(s)
Meat and offal: cattle, pigs and horses: 1 day
Milk: cattle: zero hours
5. PHARMACOLOGICAL or IMMUNOLOGICAL PROPERTIES
R(+) - cloprostenol is a synthetic prostaglandin belonging to the genito urinary system and sex hormones.
ATCvet code:QG02AD90
5.1 Pharmacodynamic properties
Genestran contains the active substance R(+) - cloprostenol, the biologically active component of the synthetic prostaglandin cloprostenol which acts similarly to the naturally occurring endogenous PGF2α.
Since Genestran contains only the biologically active component R(+) - cloprostenol, low doses are sufficient to produce luteolytic and/or stimulatory effects on the myometrium.
5.2 Pharmacokinetic particulars
Cloprostenol is reabsorbed rapidly. As demonstrated in cattle, highest plasma concentrations (Tmax) are reached within one hour and decline with a t½ of between 40 to 80 minutes. Elimination occurs in the urine and faeces.
