23 lip 2021 · In the universal formula (or “desired over have method”), the desired amount (D) is the dose prescribed and the amount on hand (H) or the amount you “have” is the available dose or concentration. The quantity (Q) is the form and amount in which the drug is supplied (i.e. tablet, capsule, liquid).
