The gut
• treatment of diarrhoea - fluids po if possible, iv if not
• do not give antibiotics unless bacteria are invading mucosa - they often cause diarrhoea
• vomiting - iv fluids, antiemetics only for persistent vomiting
• ulcers - H2 antagonists, proton pump inhibitors, prostaglandins or sucralfate - not antacids or NSAIDs
• drugs which increase motility - metaclopramide, cisapride, erythromycin
• drugs which reduce motility - codeine
• colitis - sulphasalazine
Bloat
• prevention is better than cure
• in emergency relieve ruminal tympany - try stomach tube first
• treatment - polyethoxylated alcohols, check rest of herd
• prevention - good husbandty or monensin

The gut

problem drugs
vomiting   fluids, anti-emetics - but treatment depends on cause
diarrhoea fluids, motility reducers
(antibiotics, anti-inflammatories, anthelmintics) depending on cause
ulcers proton pump inhibitors, coating agents, H2 antagonists
ileus prokinetic drugs
colic analgesics, fluids, spasmolytics depending on cause
constipation laxatives
bloat non-ionic surfactants, ionophores for prevention

All these problems are usually signs of underlying disease, so treating them will not necessarily cure the animal. Failure to treat vomiting and diarrhoea can rapidly lead to shock.
