What results when the combined effect of two different drugs taken together exceeds the sum of the individual drugs administered alone?

Options:

A) Hyperadditive

B) Antagonistic

C) Cross-tolerance

D) Cross-dependence

A) Hyperadditive

Explanation:

Hyperadditive is what results when two drugs  are added together to produce an amplified effect greater than the effect of the sum the individual drugs administered independently. The effect of this drug interaction is triple. I.e. 1 + 1= 6 Synergistic drug interaction results in hyperadditive. Examples of such drug interaction that results in hyperadditive are heart medication plus licorice, ulcer medication plus Coumadin, ibuprofen plus Coumadin.
