w/ w (weight in weight = g) xg drug (number of g in the drug)/ 100 g product (100 g in the final product)

v/ v (volume in volume = mL) xmL drug/ 100 mL product
duration of therapy (how long the IV bag will last) = hrs volume of fluid (amount of drug to be infused)/ IV flow rate (mL/hr)
IV flow rate = mg/hr volume of fluid/ duration of therapy
volume of fluid given per hr (amount of drug in mg/hr) = mg/hr total amount of drug/ time of infusion
quantity of the IV bags needed in 24 hrs = bag IV flow rate x 24 hours (mL/hr x 24 hrs)
