Sucralfate/Carafate | A gastroprotectant used to bind stomach acit and coat ulcers |
Metronidazole/Flagyl | An antibiotic for anaerobic bacteria, andtiemetic |
Metoclopramid/Reglan | Stimulates upper GI motility and is antiemetic |
Prednisone | Corticosteroid that can be used as an antiinflammatory or immunosuppresive drug. *Can cause gastric ulceration, expecially if used with NSAIDs |

What is the difference between vomiting and regurgitation? | Vomiting is using abs Regurgitattion is no effort |
Esophagitis | Inflammation of thye esophageal mucosa |
Gastric Ulcers | An erosion through the gastric mucosa, +/- muscular layer, +/- serosa |

Pythiosis | Ifection with Pythium sp, a fungus-like organsim that is found in freshwater. Can cause cutaneous lesions, too. |
Inflammatory Bowel Disease | An immuse-mediated disease in which imfalmmatory cells(WBCs) accumulate in the lining of the SI & LI |
SI parasitism | Most GI parasites are found in the SI- not acidic and slow transit. |
Lymphangiecasia | A chronic disease of imparied lymphatic drainage in the Si that results in the lymph being dumped into the SI lumen instead of returning to the blood stream. Creates a protein-losing enteropathy (PLE) and loss of lymphocytes |
SI Neoplasims | Adenocarcinomas, Lymphoma, Mast Cell Tumor |
Intussusception | A telescoping of the SI, usually occurs at the ileocecocolis junction. Usually juvenile dogs. Causes intestinal obstruction and vascular compromise |
Pancreatitis | Imflammation of the exocrine pancreas |
