    you have lactose "qs" meaning add whatever amount of lactose you need to make minimum weighable quantity.

    you have a minimum weighable quantity (MWQ) of 80mg

    you want 2mg of hydromorphone HCl in each pill

    the idea is you want to weigh out just enough of the mix in each capsule, 80mg

    ********

    so 60*2mg = 120mg Hydromophone HCl

    and 60*(80mg - 2mg) = 4680mg lactose = 4.680g lactose

    mix together and weight 80mg into each capsule

    So minimum weighable quantity is 80 mg? So weigh out 80mg HMHcl???

    Did you want weight per capsule or for making a batch?

    Doesn't make sense to me and I can usually work all dosage problems!
