Background: Currently available antihyperglycemic agents (AHAs), despite being effective, do not provide adequate glycemic control in some cases and are associated with side effects. A sodium glucose co-transporter 2 inhibitor, canagliflozin, is a newer AHA, which acts by decreasing the reabsorption of filtered glucose thereby elevating the urinary glucose excretion in diabetics.
Areas covered: This systematic review was completed to assess the clinical effectiveness and safety of canagliflozin in T2DM. A literature search in PubMed, MEDLINE, Cochrane and ClinicalTrials.gov was conducted for randomized clinical trials of canagliflozin as an AHA by applying predetermined inclusion and exclusion criteria. Total 13 studies were included in the systematic review. The main outcomes assessed were change in HbA1c and fasting plasma glucose.
Expert opinion: Canagliflozin monotherapy or combination therapy has the potential to decrease inadequately controlled hyperglycemia in T2DM. It acts by a novel insulin independent mechanism which complements the action of the existing AHA and improves glycemic control and decreases the body weight. Safety profile of canagliflozin indicates lower number of hypoglycemic episodes. Some manageable adverse events include genital mycotic infections, urinary tract infections, osmotic diuresis-related events etc. These findings affirm the utility of canagliflozin in T2DM; however, data on long-term safety and efficacy are needed.
