4. CLINICAL PARTICULARS
4.1 Target species
Horses
4.2 Indications for use, specifying the target species
For treatment of gastric ulcers in horses.
4.3 Contraindications
Do not use in known cases of hypersensitivity to the active substance or any of the
excipients.
See section 4.5.
4.4 Special warnings for each target species
None.
4.5 Special precautions for use
Special precautions for use in animals
As the safety of the product has not been assessed in foals under 8 months of age or
weighing less than 125 kg bodyweight, the use of the product is not recommended in
these animals.
Stress (including high performance training and competition), feeding, management
and husbandry practices may be associated with the development of gastric
ulceration in horses. Individuals responsible for the well-being of horses should
consider reducing the ulcerogenic challenge by modifying husbandry practices to
achieve one or more of the following: reduced stress, reduced fasting, increased
intake of roughage and access to grazing.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
This product may cause adverse gastrointestinal effects or hypersensitivity (allergic)
reactions if accidentally ingested, particularly by children.
Do not eat or drink whilst handling or administering the product.
Wash hands or any exposed skin after use.
Any part-used sachets should be returned to the original carton and suitably stored to
prevent access by children.
In case of accidental ingestion, especially by a child, seek medical advice if
symptoms persist.
4.6 Adverse reactions (frequency and seriousness)
There are no known treatment-related clinical adverse effects.
4.7 Use during pregnancy, lactation or lay
Laboratory studies in rats and rabbits have not produced any evidence of a
teratogenic effect with omeprazole.
The safety of the veterinary medicinal product has not been established during
pregnancy and lactation in the target species; use only according to the benefit-risk
assessment by the responsible veterinarian.
4.8 Interaction with other medicinal products and other forms of interaction
Omeprazole may delay the elimination of warfarin. Interaction with drugs metabolised
by liver enzymes cannot be excluded.
Omeprazole may potentially alter benzodiazepine metabolism and prolong CNS
effects.
Clarithromycin may increase levels of omeprazole.
Omeprazole may reduce cyclosporine metabolism.
Omeprazole may decrease absorption of the drugs requiring decreased gastric pH
for optimal
absorption (ketoconazole, itraconazole, iron, ampicillin esters).
4.9 Amounts to be administered and administration route
For oral administration.
Treatment of gastric ulcers:
One administration of 2 mg omeprazole per kg body weight per day for 28
consecutive days.
Each sachet contains sufficient omeprazole to treat 200 kg body weight. Sachets
should not be subdivided. Therefore, calculate the dose required (2 mg/kg per day)
and round up to the nearest 200 kg increment. Mix the appropriate number of whole
sachets into a small amount of the horse’s feed. This product may only be added to
dry feed and the feed should not be dampened.
Body weight
range (kg)
125-200 201-400 401-600 601-800

It is recommended to associate the treatment with changes of husbandry and training
practices. See section 4.5.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
No undesirable effects related to treatment were observed following daily use for
91 days at omeprazole dosages up to 20 mg/kg in adult horses and in foals older
than 2 months.
No undesirable effects related to treatment (in particular no adverse effect on the
semen quality or reproductive behaviour) were observed following daily use for 71
days at an omeprazole dosage of 12 mg/kg in breeding stallions.
No undesirable effects related to treatment were observed following daily use for
21 days at an omeprazole dosage of 40 mg/kg in adult horses.
4.11 Withdrawal period(s)
Meat and offal: 2 days
Not authorised for use in animals producing milk for human consumption.
5. PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: drugs for peptic ulcers and gastro-oesophageal reflux
disease (GORD), Proton pump inhibitors.
ATCvet code: QA02BC01.
5.1 Pharmacodynamic properties
Omeprazole is a proton pump inhibitor belonging to the substituted benzimidazole
class of compounds. It is an antacid, for treatment of peptic ulcers.
Omeprazole suppresses gastric acid secretion by specific inhibition of the H+
/K+
-
ATPase enzyme system at the secretory surface of the parietal cell. The H+
/K+
-
ATPase enzyme system is the acid (proton) pump within the gastric mucosa.
Because H+
/K+
-ATPase is the final step involved in control of acid secretion,
omeprazole blocks secretion irrespective of the stimulus. Omeprazole irreversibly
binds to the gastric parietal cell H+
/K+
-ATPase enzyme that pumps hydrogen ions
into the lumen of the stomach in exchange for potassium ions.
The full effect on the inhibition of acid secretion is reached by five days after the first
administration.
5.2 Pharmacokinetic particulars
The absorption of omeprazole after oral administration as gastro resistant granules is
rapid with time to maximum plasma concentrations (Tmax) of approximately one hour
after dosing. Mean peak concentration (Cmax) is approximately 236.7 ng/ml after
dosing with 2 mg/kg. There is a significant first-pass effect following oral
administration. Omeprazole is rapidly metabolised principally into glucuronides of
demethylated and hydroxylated omeprazole sulphide (urinary metabolites) and
methyl sulphide omeprazole (biliary metabolite) as well as into reduced omeprazole
(both). After oral administration at 2 mg/kg, omeprazole is detectable in plasma for
8 hours after treatment. Omeprazole is eliminated quickly, mainly by urinary route (43
to 61% of the dose), and to a smaller extent by faecal route, with a terminal half-life
ranging from approximately 0.4 to 2.8 hours.
After repeated oral administration, there is no evidence of accumulation.
