Low Risk

Moderately safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.

Trandolapril and its active metabolite trandolaprilat are angiotensin converting enzyme inhibitors (ACEI) used in the treatment of hypertension and myocardial infarction.
Oral administration every 12 - 24 hours.

Since the last update we have not found published data on its excretion in breastmilk.

Other compounds from the same group (ACEI) are not excreted in breastmilk in significant amounts, but until there is more information about this drug in relation to breastfeeding, safer known alternatives are preferable (Anderson 2018, Hale 2017 p946).

Due to its possible renal toxicity in preterm infants, it is preferable to avoid its use during the neonatal period in case of prematurity. (Serrano 2015).

The protective role of breastfeeding against maternal hypertension has been proven (Park 2018).


  • Captopril ( Safe. Compatible. Minimal risk for breastfeeding and infant.)
  • Enalapril ( Safe. Compatible. Minimal risk for breastfeeding and infant.)

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.
