A drug/medication has to travel through bloodstream to site of action to produce a change in organ or tissue
the drug is then metabolized by enzymes eliminated and filtered by liver
alcohol has same reaction as a medication with target organ as the brain
but alcohol alters availability of other drugs by competing with enzymes and metabolites needed for prescribed drug to be effective
alcohol sometimes decreases drug/med availability hence need for higher doses of medication some drugs needs weeks to be eliminated because of alcohol
toxic chemicals can be formed by interaction of meds and alcohol and damage organs as well.
liver damage occurs from many things but it becomes overwhelmed with the work of eliminating toxins
