Question

Quizplus · Accepted Answer

Ionized drugs have a charge, which makes it harder for them to cross the renal tubular membranes and be excreted in the urine. Non-ionized drugs, in contrast, have no charge and can cross the membranes more easily. Lipid-soluble drugs can also cross the membranes easily as they can dissolve in the lipid-rich membrane. Water is not a drug and does not need to cross the membrane to be excreted in urine.
