ANS: x @ C
A preparation can be chemically equivalent yet not biologically or therapeutically equivalent.
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

@effect or response that can be produced by a drug. The therapeutic index is the ratio of the l

ethal dose for 50% of the experimental animals divided by the effective dose for 50% of the
