CAS Number: 1405-20-5
Antibiotic drug that is usual topically used (Dermatology, ENT and Ophthalmology) At latest update no published data on excretion into breast milk were found. The small dose and low absorption to the plasma in a majority of preparations that are topically used on the eye, ear or skin make a significant excretion into the milk unlikely. Its high molecular weight makes less probable an excretion into breast milk in significant amount. Due to a poor oral bioavailability, appearance in the infant's plasma from ingested milk is regarded as nil or scanty, except in premature infants or during the immediate neonatal period who may show an increased intestinal absorption. Polymyxin E or Colistin with a very similar molecular structure is excreted into breast milk in non-significant amount. It is advisable to avoid the application of creams, gels and other products for local use that would contain paraffin (mineral oil) to prevent absorption by the infant.
CAS Number: 1405-87-4

CAS Number: 1404-26-8
