Cleaning Validation : Defining Limits and Doing MACO Calculations

(6 tablets of 100 mg). Smallest batch size B = 200 kg! (200 000 000 mg). Acceptable daily intake, ADI (µg of a / g in B) : 4 000 x 1/(0,6) x 1/1000 = 6,6 µg of a / g in B 6,6 ppm so < 10 ppm Calculate the MACO in common facilities/equipments : 6,6 X 200 000 = 1 320 000 µg 1st: traditional approach…
