New Efudex-Like Compound: Percentage Strength?

Efudex cream is 5% flurouracil and is available in a 25 gram tube. What would be the new percentage strength if in the compounding lab, you added an additional 2 grams of flurouracil powder to the whole tube of efudex cream, making a new compounded product?

New, Compounded Product: 8.3% percentage strength of fluroouracil
by: David

First, we add the 2 grams of the product to the 25 grams of Efudex to get the total weight...

2gms + 25 grams = 27 total grams.

Next, we figure how much of 25 grams is 5%?

0.05 X 25 = 1.25 grams

Now we add 1.25 grams and 2 grams of the efudex product together...

1.25grams + 2 grams = 3.25 grams

Next, to get the new percentage strength, we divide the new total volume by the actual concentrate...

27 grams divided by 3.25 grams =

8.3% percentage strength

Thank you for the question!
