Introduction
In this meta-analysis, we aimed to systematically compare the adverse drug events associated with sitagliptin (100 mg) versus canagliflozin 100 or 300 mg in patients who were treated for type 2 diabetes mellitus (T2DM).
Methods
Online databases were searched for relevant studies comparing sitagliptin (100 mg) versus canagliflozin. Adverse drug events were considered as the clinical endpoints. The analysis was carried out by RevMan software whereby risk ratios (RR) and 95% confidence intervals (CI) were generated.
Results
Five studies with a total number of 2322 patients were included. When sitagliptin (100 mg) was compared with canagliflozin (100 mg), the endpoints of any adverse events, adverse events leading to drug discontinuation, serious adverse events, urinary tract infections, hypoglycemia, and adverse events related to hypovolemia were not significantly different: (RR 1.10, 95% CI 1.00–1.21; P = 0.05), (RR 1.20, 95% CI 0.67–2.16; P = 0.54), (RR 0.90, 95% CI 0.49–1.66; P = 0.73), (RR 1.26, 95% CI 0.77–2.08; P = 0.36), (RR 1.01, 95% CI 0.30–3.43; P = 0.99), and (RR 1.76, 95% CI 0.52–5.94; P = 0.36), respectively. However, canagliflozin was associated with increased genital mycotic infection (RR 4.32, 95% CI 2.11–8.83; P = 0.0001). When genital mycotic infections associated with sitagliptin versus canagliflozin were compared in male and female patients separately, the risk was still significantly higher with canagliflozin: (RR 7.00, 95% CI 2.44–20.06; P = 0.003) and (RR 4.02, 95% CI 2.22–7.27; P = 0.00001), respectively. The same results were obtained when sitagliptin (100 mg) was compared to canagliflozin 300 mg.
Conclusions
Canagliflozin was associated with a significantly higher risk of genital mycotic infections when compared to sitagliptin. However, the other adverse drug events were similarly manifested when sitagliptin 100 mg was compared to either canagliflozin 100 or 300 mg.
