What about breastfeeding and weak bases

... in the plasma. To increase excretion: change the urinary pH to favor the charged form of the drug: Weak acids: excreted faster in alkaline pH (anion form favored) Weak bases: excreted faster in acidic pH (cation form favored) Glomerulus acts as a negatively charged selective barrier promoting ...
