OBJECTIVES: The efficacy of maropitant (Cerenia; Pfizer Inc.) as an anti-emetic for use in dogs with ongoing emesis was evaluated in a two-phase multi-centric study conducted at veterinary clinics in France, Italy, Slovakia and the UK. METHODS: In phase I, dogs with ongoing emesis were randomised in a 1:1 ratio to either maropitant (32 dogs) or metoclopramide (34 dogs). In phase II, dogs were randomised in a 2:1 ratio to maropitant (77 dogs) or metoclopramide (40 dogs). Maropitant was administered subcutaneously at 1 mg/kg/day for up to five days. Metoclopramide was administered as recommended on the product labels as licensed at 0.5 to 1 mg/kg/day subcutaneously or orally with the daily dose divided over two to three administrations per day for up to three to five days. RESULTS: In phase I, 97 per cent of dogs treated with maropitant and 71 per cent of dogs treated with metoclopramide did not vomit after treatment (P<0.01). The mean number of emetic events after maropitant treatment was significantly reduced compared with that after metoclopramide treatment (P=0.01). In phase II, the occurrence of emesis was lower for maropitant during the first 24 hours (P<0.0001) and for each day thereafter. CLINICAL SIGNIFICANCE: A single daily dose of maropitant was more effective than metoclopramide administered two or three times daily in the treatment of emesis caused by various aetiologies in dogs.
