Pirisudanol Maleate / Dimaleate

High Risk

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

It is the succinic acid ester of pyridoxine and deanol. It has been administered orally as a maleate in the treatment of impaired mental function, with no published evidence.

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

The absence of known pharmacokinetic data does not allow to predict a possible excretion in breast milk.

Product with practically no bibliographical references or technical data sheet, marketed in very few countries. It is considered a drug of low therapeutic utility. (SEFAP 2012, INSALUD 2001)


We do not have alternatives for Pirisudanol Maleate / Dimaleate.

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.
