ACTOplus met is there when combination therapy is needed
ACTOplus met significantly reduces A1C beyond metformin alone[1,2]
- Additional 1.0* percentage point reduction in A1C with ACTOS 45 mg added to metformin (24 weeks)
- ACTOS 30 mg QD provided an additional 0.8 percentage point reduction in A1C vs baseline when added to metformin*[1,2]
- Low incidence of hypoglycemia when ACTOS is used with metformin[3]
- A1C reductions were sustained beyond 2.5 years
ACTOS (pioglitazone HCI) added to metformin†

ACTOplus met provides additional improvements in both triglycerides and HDL-C vs metformin alone
ACTOS added to metformin[2,4]

In patients on stable statin therapy, switching from rosiglitazone plus metformin to ACTOS plus metformin improved key lipid parameters[2]
- Prior to conversion, patients with type 2 diabetes and dyslipidemia were taking[2]:
- Rosiglitazone ≥ 90 days
- Metformin
- A stable dose of a statin§
- After conversion, patients were taking[2]:
- ACTOS
- Metformin
- A stable dose of a statin§
- Key lipid parameters improved after conversion to ACTOS plus metformin[2]

- All lipid changes were independent of glycemic control, which remained stable after treatment conversion from rosiglitazone to ACTOS[2]
†Results of a subset analysis from a randomized, double-blind, placebo-controlled trial in patients with type 2 diabetes and established cardiovascular disease. Mean duration of follow-up: 34.5 months. A1C data reported for those patients taking metformin at baseline and randomized to receive ACTOS (titrated up to 45 mg QD), n = 253. Baseline A1C: 7.63%. Change from baseline A1C at final visit: –0.83% (significant vs placebo; P < 0.0001). By study’s end, 81% of patients had neither switched to nor added sulfonylurea or insulin (vs 65% for placebo).
‡Results from a 104-week, double-blind, randomized, double-dummy, multicenter, parallel-group study using ACTOS 15, 30, or 45 mg QD plus metformin. Mean change at endpoint statistically significant vs baseline at P < 0.0001. Baseline LDL-C: 129.0 mg/dL, total cholesterol: 217.8 mg/dL, n = 310.
§Concomitant use of a statin included: atorvastatin (51%), simvastatin (30%), pravastatin (8%), fluvastatin (5%), lovastatin (4%), or rosuvastatin (3%). 305 subjects were enrolled to receive ACTOS in combination with a stable statin therapy (276 completed; 90.5%). Patients taking antidiabetic therapy during the pre-study period were on metformin (49.7%), sulfonylureas (34.7%), and/or insulin (31.5%). 13% of all patients were on a stable dose of an additional lipid-lowering agent. Rosiglitazone dosing at the beginning of the screening period: 38.8% of patients were on 4 mg and 54.4% were on 8 mg (total daily dose). 47% of patients were titrated to 45 mg during the treatment period.
¶Results from a 17-week, open-label, single-arm, multicenter study of patients with type 2 diabetes and dyslipidemia. Baseline triglycerides: 314.7 mg/dL, HDL-C: 42.6 mg/dL, total cholesterol: 198.8 mg/dL, n = 183.
Management of type 2 diabetes should also include nutritional counseling, weight reduction as needed, and exercise.
While ACTOS may confer some lipid benefits, ACTOS is not indicated to treat lipid disorders and should not be used as a substitute for lipid-lowering therapy.
The effects of these lipid changes on morbidity and mortality have not been determined.
Important Safety Information for ACTOS® (pioglitazone HCl), ACTOplus met® (pioglitazone HCl and metformin HCl), and duetact™ (pioglitazone HCl and glimepiride)
Contraindications for ACTOplus
met
1. Renal disease or renal dysfunction (serum creatinine levels
≥1.5 mg/dL [males], ≥1.4 mg/dL [females]). 2. Acute or chronic
metabolic acidosis, including diabetic ketoacidosis, with or without
coma.[3]
ACTOplus met should be temporarily discontinued in patients undergoing radiologic studies involving intravascular administration of iodinated contrast materials, because use of such products may result in acute alteration of renal function.[3]
Contraindication for duetact
Diabetic ketoacidosis (DKA), with or without coma. DKA should
be treated with insulin.[5]
Boxed Warning for ACTOplus
met: Lactic Acidosis
Lactic acidosis is a rare but serious metabolic complication
that can occur due to metformin accumulation during therapy with
ACTOplus met.[3]
The reported incidence of lactic acidosis in patients receiving
metformin HCl is very low (approximately 0.03 cases/1000 patient-years),
but may be fatal in approximately half these instances. Reported
cases have occurred primarily in diabetic patients with significant
renal insufficiency. Patients with congestive heart failure requiring
pharmacologic management, in particular those with unstable or
acute congestive heart failure who are at risk of hypoperfusion
and hypoxemia, are at increased risk of lactic acidosis. The risk
of lactic acidosis increases with the degree of renal dysfunction
and the patient's age. The risk of lactic acidosis may, therefore,
be significantly decreased by regular monitoring of renal function
in patients taking ACTOplus met and by use of the minimum
effective dose of ACTOplus met. In particular, treatment
of the elderly should be accompanied by careful monitoring of
renal function. ACTOplus met should be promptly withheld
in the presence of any condition associated with hypoxemia, dehydration,
or sepsis. Because impaired hepatic function may significantly
limit the ability to clear lactate, ACTOplus met should
generally be avoided in patients with clinical or laboratory evidence
of hepatic disease.[3]
Patients should be cautioned against excessive alcohol intake
when taking ACTOplus met. In addition, ACTOplus
met should be temporarily discontinued prior to any intravascular
radiocontrast study and for any surgical procedure.[3]
The onset of lactic acidosis often is subtle and accompanied only
by nonspecific symptoms such as malaise, myalgias, respiratory
distress, increasing somnolence, and nonspecific abdominal distress.
Patients should be made aware of the possible importance of such
symptoms and instructed to notify their health professional immediately
if they occur.[3]
Cardiac considerations
Like other thiazolidinediones (TZDs), pioglitazone can cause fluid
retention when used alone or in combination with other antidiabetic
agents, including insulin. Fluid retention may lead to or exacerbate
heart failure. Patients should be observed for signs and symptoms
of heart failure.[1]
In clinical trials, a small number of patients with a history
of previously existing cardiac disease were reported to develop
congestive heart failure (CHF) when treated with pioglitazone
in combination with insulin. Reports of CHF have been received
in postmarketing experience in patients with and without previously
known heart disease.[1]
Patients with NYHA Class III and IV cardiac status were not studied
in pioglitazone clinical trials; therefore, ACTOS, ACTOplus
met, and duetact are not indicated in these patients.[1]
Patients with systolic heart failure (NYHA Class II) naïve to
pioglitazone therapy should be initiated at the lowest approved
dose. Patients should be monitored for signs and symptoms of CHF
exacerbation.[1]
Cardiac considerations for duetact
The UGDP trial found that tolbutamide, a sulfonylurea, was associated
with an increased risk of cardiovascular mortality. Glimepiride
was not studied in this trial; however, it is prudent to consider
that this warning may apply to all sulfonylureas.[5]
Hepatic safety
Reports of hepatitis and of hepatic enzyme elevations to three
or more times the upper limit of normal (ULN) have been received
in postmarketing experience with pioglitazone. Very rarely, these
reports have involved hepatic failure with or without fatal outcome,
although causality has not been established.[1]
Liver enzymes, including serum ALT, should be evaluated in all
patients at initiation of therapy with ACTOS, ACTOplus
met, or duetact, and periodically thereafter per the
clinical judgment of the healthcare professional. If ALT >2.5X
ULN at baseline or if the patient exhibits clinical evidence of
active liver disease, do not initiate therapy with ACTOS, ACTOplus
met, or duetact.[1,3,5]
Other considerations
ACTOS, ACTOplus met, and duetact may also be
associated with hypoglycemia, edema, anemia, weight gain, and/or
ovulation in premenopausal, anovulatory women. Adequate contraception
should be recommended for premenopausal women.[1,3,5] Macular edema has
been reported in some diabetic patients receiving TZD therapy,
although a causal relationship is unknown. Persons with diabetes
should have routine eye exams, and be instructed to immediately
report any visual changes to their healthcare provider.
Other considerations for duetact
As with all sulfonylureas, severe hypoglycemia may occur. Elderly,
debilitated, or malnourished patients, or patients with adrenal,
pituitary, renal, or hepatic insufficiency may be more sensitive
to the glucose-lowering effect of sulfonylureas and should be
started on the lowest dose of duetact.[5]
Well-tolerated therapy
In US placebo-controlled ACTOS monotherapy clinical trials, the
most common adverse events (≥5%) were upper respiratory tract
infection, headache, sinusitis, myalgia, tooth disorder, aggravated
diabetes mellitus, and pharyngitis.[1]
In clinical trials using pioglitazone in combination with metformin, the most common adverse events (≥5%) were upper respiratory tract infection, diarrhea, nausea, headache, urinary tract infection, sinusitis, dizziness, lower limb edema, and increased weight.[3]
In clinical trials using pioglitazone in combination with a sulfonylurea, the most common adverse events (≥5%) were hypoglycemia, upper respiratory tract infection, weight increase, headache, diarrhea, edema, urinary tract infection, pain in limb, and nausea.[5]
Indications and usage
ACTOS is indicated as an adjunct to diet and exercise to improve
glycemic control in patients with type 2 diabetes. ACTOS is approved
for use as monotherapy and in combination with sulfonylureas,
metformin, or insulin when diet and exercise plus the single agent
do not result in adequate glycemic control.[1]
ACTOplus met is indicated as an adjunct to diet and exercise to improve glycemic control in patients with type 2 diabetes who are already treated with a combination of pioglitazone and metformin, or whose diabetes is not adequately controlled with metformin alone, or for those patients who have initially responded to pioglitazone alone and require additional glycemic control.[3]
Duetact is indicated with diet and exercise as a once-daily combination therapy to improve glycemic control in patients with type 2 diabetes who are already treated with a combination of pioglitazone and a sulfonylurea or whose diabetes is not adequately controlled with a sulfonylurea alone, or for those patients who have initially responded to pioglitazone alone and require additional glycemic control.[5]
ACTOS, ACTOplus met, and duetact should not be used in patients with type 1 diabetes. Management of type 2 diabetes should also include nutritional counseling, weight reduction as needed, and exercise.[1,3,5]
