10 Drug Maternal gut and liver Maternal plasma Infant gut Infant plasma Oral bioavailability varies High (>90%) Low (<50%) Acetaminopen Acyclovir Lorazepam Azithromycin Metronidazole Budesonide Minoxidil Sulfasalazine Dilution of all drugs leads to low concentrations in mother’s plasma Only drugs are not protein-bound can pass into milk Drug protein binding High Low Bepridil >99% Bisoprolol 30% Diazepam 99% Cyclophosphamide 13% Diclofenac >99% Ranitidine 15% Propranolol 90% Primidone <20% Oral bioavailiability varies Usually very low levels (often undetectable) Route of drugs from mother to baby via breastmilk

13 Avoid unnecessary drug use and limit use of OTC products Assess the benefit/risk ratio for both mother and infant Avoid use of drugs known to cause serious toxicity in adults or children Choose drugs for the mother that have known and established information about their pharmacokinetics and toxicity and have low concentrations in breast milk and low relative infant dose Avoid new drugs if possible Drugs licensed for use in infants do not generally pose a hazard Neonates (esp. premature infants) are at greater risk from exposure to drugs via breast milk Route of administration (minimum amount of drug to the infant) Avoid long-acting preparations Monitor Infants exposed to drugs via breast milk for unusual signs/symptoms 약물 선택 시 일반적인 고려사항

14 Choose medications :- shortest T 1/2, highest protein binding ability, poorest oral absorption, lowest lipid solubility, well-studied in infants. Avoid feeding the infant at the time of peak concentration of the drug in milk. To minimize drug level in the milk - administer the drug at / immediately after the infant feeds. Avoid long-acting drug. In case of no available alternative, medication is best taken just prior to the longest sleep of the infant. 약물 선택 시 일반적인 고려사항

15 Infants should be monitored for AE :- feeding, sedation, irritability, rash, etc. For some medications with potential harm, temporary suspension of breastfeeding may be necessary. ( Advice the mother about milk expression & cup feeding instead of bottle feeding to avoid nipple confusion) Withhold breastfeeding temporarily if the drug is only used for a short duration. 약물 선택 시 일반적인 고려사항
