Alteplase

Compatible

Safe product and/or breastfeeding is the best option.

Synthetic recombinant protein formed by a sequence of amino acids that are identical to Human Tissue Plasminogen Activator (t-PA) which is found in colostrum and mature milk (Heegaard 1997, Marshall 1986). It is used in the emergency treatment of myocardial infarction, ischemic stroke, and pulmonary emboli. Intravenous administration.

At the date of the last update we did not find any published data on its excretion in breast milk.

Its rapid metabolism (elimination half-life of 5 minutes) and very high molecular weight make its excretion in breast milk unlikely.

Even more, its low oral bioavailability makes it difficult for it to pass into the infant's plasma from ingested breast milk since, due to its protein nature, it is degraded in the gastrointestinal tractand is not absorbed.

Alternatives

We do not have alternatives for Alteplase since it is relatively safe.

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.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
