High Risk

Poorly safe. Evaluate carefully. Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives). Read the Comment.

Amrinone is a phosphodiesterase type 3 inhibitor, similar to milrinone, with positive vasodilator and inotropic properties. Indicated in the treatment of heart failure. Intravenous administration. There are many side effects and increased mortality with oral use.

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

Its pharmacokinetic data (low molecular weigh and low protein binding) make it likely that it would pass into breast milk in amounts which could be significant.

Amrinone and milrinone have a slower elimination rate in newborns and young infants (Laitinen 2000, Ramamoorthy 1998) and a higher risk of potentially serious side effects.

Until more published data is known about this drug in relation to breastfeeding, known safer alternatives are preferable (Kearney 2018), especially during the neonatal period and in the event of prematurity.

If used during lactation: express and discard breast milk and wait to breastfeed 10 to 15 hours after administration.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
