Question

1. synergism refers to: two drugs producing a greater combined effect than individually two drugs canceling each other out two drugs causing no effect two drugs always causing death clear all

Explanation:

Synergism in the context of drugs (or substances) is defined as the interaction where the combined effect of two agents is greater than the sum of their individual effects. Let's analyze each option:

• Option 1: "Two drugs producing a greater combined effect than individually" matches the definition of synergism.
• Option 2: "Two drugs canceling each other out" describes antagonism, not synergism.
• Option 3: "Two drugs causing no effect" is not related to synergism.
• Option 4: "Two drugs always causing death" is an extreme and incorrect description of synergism, as synergism is about the magnitude of effect, not necessarily lethality.

Answer:

A. Two drugs producing a greater combined effect than individually (assuming the first option is labeled A, adjust the label as per the actual question's numbering if different)
