Pharmacoeconomic procedures, such as Charge-advantage, Charge-usefulness, Price tag-minimization, and cost-utility analyses Enjoy a useful purpose in allocating restricted well being treatment assets (Reeder, 1995). These analyses present useful info necessary to reduce expenses related to the use of pharmaceutical items.
