It is a non-cardioselective beta blocker
It is used in the treatment of glaucoma and ocular hypertension,
Topical administration as eye drops, one drop every 12 to 24 hours.

Since the last update we have not found any published data on its excretion in breast milk.

Its pharmacokinetic characteristics (large volume of distribution and high pKA), make it very unlikely its excretion into breast milk in significant amounts.

Absorption should be minimized by closing the eye after instillation, applying pressure for 1 to 5 minutes with your finger on the tear duct at the inner corner of the eye and administering the dose immediately after nursing (Blumen 2020, Belkin 2020, Méndez 2012, Johnson 2001).

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