Which classification uses letters to describe therapeutic potential?

Which classification uses letters to describe therapeutic potential?

• A. Numerical Classification
• B. FDA Classification
• C. Letter Classification
• D. Therapeutic Index

Answer: (C)

Letters are used in some drug classification schemes to rate therapeutic potential with a simple grade. This is the Letter Classification approach, which assigns letter categories to indicate how favorable a therapy’s potential is, with higher grades implying greater promise. The other options describe different concepts: a numerical system would use digits, the FDA Classification relates to regulatory status and approval, and the Therapeutic Index is a numeric ratio of toxic dose to effective dose, not a labeling scheme for potential. So, using letters to describe therapeutic potential is the best fit.
