← Human Body & HealthIf a burn injury compromises the skin's barrier function, which consequence follows regarding transdermal drug delivery?
A)Drug absorption decreases uniformly.
B)Absorption of lipophilic drugs increases.✓
C)Absorption becomes independent of molecule size.
D)Inflammation suppresses all drug diffusion.
💡 Explanation
Burn injury disrupts the stratum corneum, which normally limits diffusion of substances, because the skin barrier function is compromised; therefore, lipophilic drugs exhibit increased absorption due to preferential partitioning into the damaged lipid matrix, rather than decreased absorption or size independence, and inflammation modulates but doesn't halt diffusion.
