Biotransformation of xenobiotics, in Casarett and Doull's Toxicology: Because the capsule dissolves in the mother's intestines, the uncoated drug in the breast milk is unlikely to make it past the baby's stomach and into the bloodstream. If patient is stabilized on one brand, it should not be changed, because if the bioavailability is decreased the drug will have less effect or if the bioavailability is increased, it might lead to toxicity. If dissolution time is more, bioavailability will be less and vice versa.
