Diabetes is a very common condition, especially among older adults. There are numerous benefits associated with improved glycemic control. However, achieving glycemic targets can be challenging, particularly for older adults with comorbidities. In recent years more oral antihyperglycemic agents have become available to better manage diabetes, and there are many pharmacological therapies currently in development. In order to select the most appropriate agent to use as monotherapy or in combination for an individual patient, it is important to be familiar with the mechanism, efficacy, safety, and cost of the various antihyperglycemic agents.
Key words: diabetes, older adults, oral antihyperglycemic agents, monotherapy, combination therapy.
