Drug use and breastfeeding.

Area of Science:

• Pharmacology
• Lactation Physiology
• Pediatric Drug Safety

Background:

• Breastfeeding provides numerous maternal and infant health benefits.
• Maternal drug use during lactation can pose risks to the infant.
• Accurate information on drug transfer into breast milk is essential.

Purpose of the Study:

• To review the benefits and risks of breastfeeding concerning maternal drug use.
• To elucidate the physiological processes of lactation and drug effects on milk production.
• To define objective measures for assessing infant drug exposure via breast milk.

Main Methods:

• Review of lactation physiology and drug transport mechanisms into milk.
• Definition and application of absolute and relative infant dose calculations.
• Comprehensive review of commonly used drugs (analgesics, neurological, endocrine, psychotropic, antihypertensive) and herbal preparations.

Main Results:

• Detailed description of drug passage into milk and factors influencing infant exposure.
• Introduction of critical descriptors like absolute and relative infant dose for objective exposure measurement.
• Analysis of drug classes, including analgesics, anti-inflammatories, neurological, endocrine, psychotropic, and antihypertensive agents.

Conclusions:

• Emphasizes the importance of risk-benefit analysis for drug use during lactation.
• Recommends strategies for minimizing infant exposure to drugs in breast milk.
• Advocates for improved experimental design and reporting in lactation drug studies.
