Chapter 7 Flashcards
absorption
The process by which medications travel through body tissues until they reach the bloodstream
action
The therapeutic effect of a medication on the body
activated charcoal
An oral medication that binds and adsorbs ingested toxins in the gastrointestinal tract for treatment of some poisonings and medication overdoses. Charcoal is ground into a very fine powder that provides the greatest possible surface area for binding medications that have been taken by mouth; it is carried on the EMS unit.
adsorption
The process of binding or sticking to a surface
agonist

antagonist
A medication that binds to a receptor and blocks other medications
