Drug-drug interaction is definitely as the relationship that exists between two drugs when administered together or at the same time.

This relationship that exists between the drugs could be:

  • Synergistic relationship or

  • Antagonist relationship.

A synergistic relationship is the type of relationship that occurs between two drugs where by the total effect of the drugs are greater than the sum of the individual effects of each drug.
