a) True
b) False

Answer 1

Potentiation occurs when two drugs with the same action are used together, resulting in an increase in their action.

Step-by-step explanation:

Potentiation occurs when two drugs that have the same action are used in combination, resulting in an increase in the action of both drugs.

For example, when two antibacterial drugs, trimethoprim and sulfamethoxazole, are administered together, they provide a synergistic interaction. Individually, these drugs provide only bacteriostatic inhibition of bacterial growth, but combined, they are bactericidal.
