Question

Quizplus · Accepted Answer

Drugs that are suspended in oils or lipid-soluble solvents can be carried across the plasma membranes of the epidermal cells because the epidermal cell membranes are primarily composed of lipids. This allows for the drugs to dissolve and diffuse through the membrane. Water and alcohol-based drugs are less effective at crossing the lipid-rich cell membranes. Sebum is a lipid-rich substance secreted by sebaceous glands but is not typically used as a carrier for drugs. Blood is not a suitable carrier for drugs to cross the plasma membranes of epidermal cells.
