What is a Potency Ratio?

A potency ratio is a measure used in pharmacology to compare the effectiveness of two drugs. It is calculated by dividing the dose of a standard drug by the dose of a test drug required to achieve the same effect. This ratio helps in determining how much more or less potent the test drug is compared to the standard drug. A higher potency ratio indicates that the test drug is less potent, while a lower potency ratio indicates that the test drug is more potent.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ PR = \frac{50}{25} = 2 \]

The potency ratio would be 2.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ PR = \frac{100}{50} = 2 \]

The potency ratio would be 2.
