A glutamate antagonist, indicated in the treatment of amyotrophic lateral sclerosis.
Oral administration in two daily doses.

Its pharmacokinetic data (large volume of distribution and high percentage of protein binding) explain the very low transfer into breastmilk observed.

In addition, absorption decreases with fatty foods, so that the little amount that does reach breastmilk will be less absorbed by the infant.

Until there is more published data on this drug in relation to breastfeeding, known safer alternatives during the neonatal period and in the event of prematurity may be preferable.
