Which of the following is NOT a factor that influences absorption?

Absorption depends on how and where a drug enters the body and then moves into the bloodstream. The route determines the site of absorption and the barriers it must cross. Lipid solubility affects how easily a drug passes through membranes; more lipid-soluble drugs cross membranes more readily. Blood flow to the absorption site matters because good perfusion helps maintain the concentration gradient and moves the drug into circulation more quickly. The color of the medication is not part of these processes; it’s a visual characteristic and does not change dissolution, permeability, or perfusion. So two identical drugs with different colors are typically absorbed the same way, all else being equal.
