Overview of Using Pantoprazole in Dogs and Cats
- Pantoprazole, also known by the brand names Protonix® and Pantoloc®, is used to prevent and treat stomach ulcers and gastric acid related diseases in dogs and cats. It has been used with human medicine for years and is growing in popularity for use in dogs and cats.
- Normally, the stomach produces gastric acid to assist in digestion. Under certain conditions, however, this acid can injure the lining (mucosa) of the stomach. The result can be stomach ulcers or erosions (“scratches”) in the stomach lining. Ulcers are also a common consequence of treatment with some drugs, especially NSAID drugs, such as aspirin.
- When there is a risk of ulcer formation, there are many ways to heal the stomach or protect the lining. These anti-ulcer treatments can be classified as antacids (Maalox®), H2 blockers (Pepcid AC®), proton pump blockers (Prilosec®) and prostaglandin analogs, such as the drug Misoprostol and Pantoprazole.
- Pantoprazole inhibits stomach acid secretions and has a protective effect on blood flow and the lining of the stomach wall.
- Pantoprazole is a prescription drug and can only be obtained from a veterinarian or by prescription from a veterinarian.
- This drug is not approved for use in animals by the Food and Drug Administration but it is prescribed legally by veterinarians as an extra-label drug.
