Proton pump inhibitors: only omeprazole (Gastroguard) is licensed for horses.  Given PO once daily (4mg/kg) for 3-4 wks, most effective drug at controlling HCl secretion (decreases basal and stimulated release)

==Prevention==

Gastroguard at lower dose (1mg/kg) daily for 3-4wks

Gastroguard at lower dose (1-2mg/kg) daily for 3-4wks (100, 107-109 in Sanchez)
 +
Prophylaxis in foals controversial as gastric acidity may be protective against bacterial translocation (Sanchez).  It may be beneficial in foals receiving substantial doses of NSAIDs for orthopaedic pain (Sanchez)
 +
Management: diet, training, exercise, stress (company, toys)
 +
Pasture turnout and continuous access to high quality forage especially alfalfa (Sanchez)
