ACTOPLUS MET vs SEGLUROMET
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Actoplus Met combines pioglitazone, a thiazolidinedione that improves insulin sensitivity by activating peroxisome proliferator-activated receptor gamma (PPARγ), and metformin, a biguanide that decreases hepatic glucose production and improves peripheral glucose uptake.
SEGLUROMET is a fixed-dose combination of ertugliflozin and metformin. Ertugliflozin is a sodium-glucose co-transporter 2 (SGLT2) inhibitor that reduces renal glucose reabsorption, increasing urinary glucose excretion. Metformin decreases hepatic glucose production, decreases intestinal glucose absorption, and improves insulin sensitivity.
ACTOPLUS MET (pioglitazone/metformin) is available as tablets of 15 mg/500 mg, 15 mg/850 mg, and 15 mg/1000 mg. The usual starting dose is 15 mg/500 mg twice daily or 15 mg/850 mg once daily, gradually titrated based on glycemic response and tolerability. Maximum recommended dose is 45 mg pioglitazone and 2000 mg metformin per day.
Initial: 2.5 mg ertugliflozin/1000 mg metformin twice daily. Titrate based on efficacy and tolerability. Maximum: 5 mg ertugliflozin/2000 mg metformin twice daily.

Pioglitazone: terminal half-life 3–7 hours (parent drug) for elimination, with active metabolites prolonging clinical effects up to 24 hours. Metformin: 6.2 hours (plasma), prolonged to 17.6 hours in renal impairment (e.g., CrCl <60 mL/min).
Ertugliflozin: terminal half-life ~16.6 hours (range 10-20 h), supporting once daily dosing. Metformin: terminal half-life ~6.2 hours (range 4-8.7 h) in patients with normal renal function; prolonged in renal impairment.
Pioglitazone: predominantly hepatic metabolism and biliary excretion of metabolites, with 15–30% recovered in urine (mostly metabolites) and the remainder in feces. Metformin: 90% excreted unchanged in urine via glomerular filtration and tubular secretion, with <10% in feces.
Segluromet (ertugliflozin and metformin) is primarily excreted via renal (ertugliflozin: ~40.9% unchanged in urine; metformin: ~90% unchanged in urine) and fecal/biliary routes (ertugliflozin: ~50.2% in feces as parent and metabolites; metformin: <1% in bile).
