Peptizole is the latest product now available to help treat and prevent gastric ulcers in horses. It contains omeprazole which reduces gastric acid secretion in the stomach. A dose is given from the graduated syringe once daily for up to 28 days. One full syringe will provide a full dose for a horse of 700kg bodyweight. If Peptizole is being given as a preventative, rather then treatment of an existing ulcer, then a quarter dose is given each day. Syringes are graduated in 50kg bodyweight divisions.

Peptizole 370 mg/g Oral Paste for Horses


Each 7 ml syringe of Peptizole contains 7.57 g of oral paste
Each gram of oral paste contains 370 mg of Omeprazole


For treatment of gastric ulcers and the prevention of recurrence of gastric ulcers.

Dosage & Administration

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 body weight (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 body weight, to reduce the recurrence of gastric ulcers during treatment.
Should recurrence occur, re-treatment at a dose rate of 4 mg Omeprazole per kg body weight (1 division of the syringe/50 kg BW) is recommended.
Prevention of recurrence of gastric ulcers: one administration per day at the
dose rate of 1 mg Omeprazole per kg body weight.
To deliver Omeprazole at the dose of 4 mg Omeprazole /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 body weight. The contents of one syringe will treat a 700 kg horse at the rate of 4 mg Omeprazole per kg body weight.
To deliver Omeprazole at the dose of 1 mg Omeprazole /kg, set the syringe plunger to the dose division equivalent to one quarter of the horse’s body weight. 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 body weight.
It is recommended to associate the treatment with changes of husbandry and training practices.

Prescription query

Sarah Wade

  • VioVet customer since 2012
  • From: North Yorkshire, United Kingdom

I have asked my vet to provide a prescription for my horse so that I can buy this from you as it is cheaper than from him. Will I need a new prescription every time I buy it?

  • Non-Executive Director

We can supply up to the amount (which should be clearly stated) which your vet allows on the written prescription. If your vet chooses to allow an extended course of treatment (which he/she is perfectly at liberty to do) then you can draw off that one prescription as you wish. It is largely down to how long your vet thinks your horse might need the medication for, and how helpful your vet wants to be. Many are very helpful if you just ask for what makes sense for you.
