Evidence to support prochlorperazine 5mg IV for PONV

I am trying to find journal/medical information to support the use of prochlorperazine 5mg IV for the treatment of nausea & vomiting. Also any studies looking at the effectiveness of prochlorperazine vs promethazine. We are trying to support the lower dose, but want to make sure that it is as effective as the usual 10mg dose usually seen. Appreciate any help.
