a) Pharmacokinetic antagonistic relationship
b) Pharmacodynamic antagonistic relationship
c) Synergistic adverse side effects
d) Synergistic therapeutic effects

A

B D

pharmacoDYNAMIC antagonistic (because thiazides cause hypokalemia & potassium sparing cause hyperkalemia) and synergistic therapeutic (because they both cause diuresis so their individual effects add up to inc diuresis more than either drug can do alone)

62
Q
