Dosage and administration
Omeprazole is effective in horses of various breeds and under different management conditions; foals as young as four weeks of age and weighing over 70 kg; and breeding stallions.
For oral administration.
Treatment of gastric ulcers;
one administration per day during 28 consecutive days at the dose rate of 4 mg omeprazole per kg bodyweight (1 division of the syringe/50 kg BW) followed immediately by a dosage regimen of one administration per day during 28 consecutive days at the dose rate of 1 mg omeprazole per kg bodyweight, to reduce the recurrence of gastric ulcers during treatment.
Should recurrence occur, re-treatment at a dose rate of 4 mg omeprazole per kg bodyweight (1 division of the syringe/50 kg BW) is recommended.
It is recommended to associate the treatment with changes of husbandry and training practices. Please see the Further Information section.
Prevention of recurrence of gastric ulcers;
one administration per day at the dose rate of 1 mg omeprazole per kg bodyweight.
To deliver omeprazole at the dose of 4 mg/kg, set the syringe plunger to the appropriate dose division for the horse’s weight. Each division on the syringe plunger delivers sufficient omeprazole to treat 50 kg bodyweight. The contents of one syringe will treat a 700 kg horse at the rate of 4 mg omeprazole per kg bodyweight.
To deliver omeprazole at the dose of 1 mg/kg, set the syringe plunger to the dose division equivalent to one quarter of the horse’s bodyweight. For example, to treat a horse weighing 400 kg, set the plunger to 100 kg. At this dose, each division on the syringe plunger will deliver sufficient omeprazole to treat 200 kg bodyweight.
