SUpporting Mothers Milk Intervention Trial (SUMMIT): A randomized controlled trial comparing different doses of domperidone for treating lactation insufficiency in mothers of preterm infants
Comparing high (60mg) vs low (30mg) dose Domperidone to increase expressed breast milk volumes in mothers of preterm infants with lactation insufficiency.
Mothers of preterm infants often struggle to produce enough breast milk to meet the daily feed requirements of their infants, especially in the longer-term. This randomized multi-centre double-blind parallel controlled trial will resolve the issue of whether a higher dose of domperidone (60 mg/day) leads to greater improvements in maternal breast milk supply compared to a lower dose (30 mg/day), while also evaluating differences in adverse events, impacts on breast milk composition, and identifying predictors of treatment response to domperidone.
