NEUPOGEN (filgrastim) prefilled syringes contain 480 ug of active constituent in each 0.8 mL. The equivalent concentration is?

Step 1. Convert micrograms to milligrams. 480 ug / 1,000 = 0.48 mg. Step 2. Calculate mg per mL. 0.48 mg / 0.8 mL = 0.6 mg/mL. Step 3. Convert to percentage (w/v). Percentage = (grams / 100 mL). 0.6 mg = 0.0006 g. (0.0006 g / 1 mL) = (X / 100 mL). X = 0.06 g. Concentration = 0.06%.
