What economic analysis is most appropriate for selecting the least costly drug alternative among treatments with equivalent outcomes?

Cost-minimization analysis is the most appropriate economic analysis for selecting the least costly drug alternative among treatments with equivalent outcomes. This is because cost-minimization analysis focuses solely on finding the least expensive treatment option without considering the potential benefits or outcomes of each treatment. Cost-benefit analysis (A) takes into account both the costs and benefits of each treatment, which may not be useful when trying to simply find the least costly option. Cost-effectiveness analysis (B) and cost-utility analysis (C) both consider the costs and outcomes of each treatment, but focus on different outcomes (effectiveness and quality of life, respectively) and may not be the most appropriate for determining the least costly alternative.
