A) Nonionized
B) Isotonic
C) Ionized
D) Hypertonic

Question

Quizplus · Accepted Answer

Lipid soluble drugs are nonpolar and therefore don't readily dissolve in water. As cell membranes are also made up of a lipid bilayer, nonpolar (lipid soluble) drugs can easily diffuse across the cell membrane. Ionized drugs, on the other hand, have a charge and are unable to pass through the membrane without a transporter. Isotonic and hypertonic refer to solutions and are not relevant to the lipid solubility of a drug.
