Objective: To review the efficacy and safety of canagliflozin (CAN) in elderly patients with type 2 diabetes mellitus (T2DM).

Data sources: Studies were identified using PubMed, International Pharmaceutical Abstracts, MEDLINE, Academic Search Premier, SCOPUS, and Google Scholar from 2011 to August 2013. The following key words were reviewed: canagliflozin, canagliflozin elderly, canagliflozin geriatrics, dapagliflozin, sodium glucose cotransporter 2 (SGLT2) inhibitors, and SGLT2 receptor inhibitors.

Data extraction: Articles evaluating CAN for diabetes that were published in English and used human subjects were selected. Fifteen clinical trials were identified and evaluated.

Study selection: Of 15 identified articles, 2 articles, 2 published posters, and unpublished information from the manufacturer were chosen based on the mean age of the study subjects.

Data synthesis: Evidence that elderly patients with T2DM have less A1C reduction with CAN is presented; the benefit on A1C is significant. Systolic blood pressure (SBP) and body weight reduction in the elderly were consistent with younger patients. Adverse effects such as increased urinary frequency, genital mycotic infections, and urinary tract infections may discourage the use of CAN in the elderly patient.

Conclusion: Treatment with CAN improves A1C levels, reduces SBP and body weight, and is overall well tolerated in older subjects with T2DM. Risks and benefits of treatment with CAN should be assessed in geriatric patients on a case-by-case basis. Safety in elderly patients was consistent with that of other phase 3 trials in the general population. Additional longterm cardiovascular studies are needed.
