What about breastfeeding and weak bases

... Weak bases: excreted faster in acidic pH (cation form favored) Glomerulus acts as a negatively charged selective barrier promoting retention of anionic compunds. I know all this, but why does drugs that are weak bases should be given with cation when given to breast feeding women? Does it has ...
