Valsartan is an angiotensin II receptor antagonist with actions similar to those of losartan.
It is indicated in the treatment of hypertension.
Oral administration once or twice a day.

At latest update, relevant published data on excretion into breast milk were not found.

A high protein-binding capacity makes excretion into breast milk unlikely. In addition, a low oral bioavailability makes difficult the absorption towards the infant's plasma from ingested milk, except in prematures or newborns who may show an increased absorption.

Until more data on this medication is available, safer alternative drugs are preferred (Rowe 2013), especially in premature babies or during the neonatal period.
