Q

Absorption of Medications:

A
  • Lipid soluble medications absorb easily through the GI membrane because the GI membrane is composed mostly of lipids.
  • Nonionized substances pass easily through the GI membrane.
  • Water soluble medications require a carrier to pass through the GI membrane (active absorption).
