Introduction
Trimetazidine (TMZ) is an anti-ischemic metabolic agent that has been shown to be efficacious in angina treatment, both in monotherapy and in combination. A new formulation of TMZ modified-release (MR) 80 mg was developed, which is to be taken once daily (od), instead of twice daily (bid) for the currently available TMZ MR 35 mg, with the aim of simplifying the medication regimen.
Methods
The present study was an international, multicenter, randomized, double-blind, parallel-group phase III study with a 12-week treatment period. The safety of TMZ MR 80 mg once daily was assessed compared to TMZ MR 35 mg twice daily, in patients previously treated successfully by the latter. Emergent adverse events (EAEs), biological parameters, vital signs, 12-lead resting ECG (electrocardiogram) and Canadian Cardiovascular Society (CCS) classification were recorded.
Results
One-hundred and sixty-five patients previously diagnosed with stable angina pectoris on treatment were randomized to receive either TMZ MR 80 mg od or TMZ MR 35 mg bid. In the TMZ MR 80 mg group, fewer patients had ≥ 1 EAE (17.1 vs. 22.9% in the TMZ MR 35 mg group). Serious EAEs were reported by three patients in each group. No EAE required dose modification, withdrawal, or temporary interruption of study treatments. Vital signs, 12-lead ECG, and laboratory parameters did not change. No worsening in CCS classes was observed with either treatment.
Conclusions
TMZ MR 80 mg od and TMZ MR 35 mg bid have similar safety profiles. This new once-daily formulation could improve patient compliance with therapy, thereby enhancing clinical benefit.
