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).

Q

“protein binding” refers to…?

A
  • “free” drug (drug not bound to protein) that will be able to create a pharmacologic response
  • When two drugs are given together that are both “highly protein-bound” drugs, the pateint is at greater risk of drug accumulation (drug toxicity).
  • Ibuprofen is a 98% protein bound drug. This means that 98% of the drug is bound to protein (albumin), and only 2% of the drug is “free”.
