Bioequivalent, If two medications have the same Chapter 2
Synergistic, Prodrugs, In bioavailability and same concentration of
a steady state active ingredient, they are said to be
bioequivalent (e.g., a brand-name drug and
the same generic drug).
Drug interactions in which the effect of a
combination of two or more drugs with
similar actions is greater than the sum of the
individual effects of the same drugs given
alone. For example, 1 + 1 is greater than 2
(compare with additive effects).
A prodrug is a drug that is inactive in its
administered form and must be metabolized
to its active form in the body, generally by
the liver, to be effective.
The physiologic state in which the amount of
drug removed via elimination is equal to the
amount of drug absorbed with each dose. (p.

this competition, there is more free, unbound
drug. If albumin is low, there is no bounding.
