Brief summary

The investigators propose to study the transfer of benznidazole into breastmilk from the blood of lactating women who receive the drug for the treatment of Chagas disease. Breastmilk and blood samples will be obtained from these patients at given times after they take the clinically indicated medication, and the concentrations in both matrices will be compared to estimate degree of transfer, which in turn will be used to evaluate potential degree of exposure of infants breastfed by these women. This study will help clarify safety of continuing breastfeeding while receiving treatment with benznidazole for Chagas disease.

Inclusion criteria

* Lactating women with Chagas disease, not treated before * Use of contraception

Exclusion criteria

* History of allergy to benznidazole or its excipients * Pregnancy * Significant heart involvement (due to Chagas disease) * Significant systemic diseases that could affect the interpretation of the results in the opinion of the principal investigator

Design outcomes

Primary

MeasureTime frameDescription
Benznidazole concentration in breastmilk and in plasmaat randomly selected time points during the 30 days of treatmentRandomly obtained breastmilk samples will be obtained to both evaluate the breastmilk / plasma concentration ratio of the drug, and to develop a population pharmacokinetics model of drug trasfer into breastmilk, if possible. Breastmilk concentrations will be used to calculate potential infant exposure through breastmilk to the medication (benznidazole) taken by the mother

Secondary

MeasureTime frameDescription
incidence of adverse drug reactions in women treated with benznidazole during lactationthroughout the 30 days of treatmentWomen receiving treatment with benznidazole while lactating, enrolled in the study will be followed according to current clinical guidelines, and monitored during the 60 days of the treatment (as per Chagas disease treatment guidelines), and monthly for 3 months after treatment completion.
