Actoplus Met XR (Pioglitazone Hydrochloride / Metformin Hydrochloride) - Summary

 
 



WARNING: CONGESTIVE HEART FAILURE AND LACTIC ACIDOSIS

Congestive Heart Failure

  • Thiazolidinediones, including pioglitazone, which is a component of ACTOPLUS MET and ACTOPLUS MET XR, cause or exacerbate congestive heart failure in some patients (see WARNINGS, Pioglitazone). After initiation of ACTOPLUS MET or ACTOPLUS MET XR, and after dose increases, observe patients carefully for signs and symptoms of heart failure (including excessive, rapid weight gain, dyspnea, and/or edema). If these signs and symptoms develop, the heart failure should be managed according to the current standards of care. Furthermore, discontinuation or dose reduction of ACTOPLUS MET or ACTOPLUS MET XR must be considered.
  • ACTOPLUS MET and ACTOPLUS MET XR are not recommended in patients with symptomatic heart failure. Initiation of ACTOPLUS MET or ACTOPLUS MET XR in patients with established NYHA Class III or IV heart failure is contraindicated (see CONTRAINDICATIONS and WARNINGS, Pioglitazone).

Lactic Acidosis

  • Lactic acidosis is a rare, but serious complication that can occur due to metformin accumulation. The risk increases with conditions such as sepsis, dehydration, excess alcohol intake, hepatic insufficiency, renal impairment, and acute congestive heart failure.
  • The onset is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, increasing somnolence, and nonspecific abdominal distress.
  • Laboratory abnormalities include low pH, increased anion gap and elevated blood lactate.
  • If acidosis is suspected, ACTOPLUS MET or ACTOPLUS MET XR should be discontinued and the patient hospitalized immediately (see WARNINGS, Metformin Hydrochloride).
 

SUMMARY

ACTOPLUS MET tablets are formulated with pioglitazone hydrochloride and immediate-release metformin hydrochloride. ACTOPLUS MET XR tablets are formulated with pioglitazone hydrochloride and extended-release metformin hydrochloride. Both ACTOPLUS MET and ACTOPLUS MET XR contain two oral antihyperglycemic drugs used in the management of type 2 diabetes: pioglitazone and metformin.

ACTOPLUS MET and ACTOPLUS MET XR are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus who are already treated with pioglitazone and metformin or who have inadequate glycemic control on pioglitazone alone or metformin alone.

Management of type 2 diabetes should also include nutritional counseling, weight reduction as needed, and exercise. These efforts are important not only in the primary treatment of type 2 diabetes, but also to maintain the efficacy of drug therapy. Prior to initiation or escalation of oral antidiabetic therapy in patients with type 2 diabetes mellitus, secondary causes of poor glycemic control, e.g., infection, should be investigated and treated.

NEWS HIGHLIGHTS

Published Studies Related to Actoplus Met XR (Pioglitazone / Metformin)

PIOfix-study: effects of pioglitazone/metformin fixed combination in comparison with a combination of metformin with glimepiride on diabetic dyslipidemia. [2011.06]
CONCLUSIONS: With comparable glycemic control, the fixed PM combination was more efficacious on HDL cholesterol improvement than the GM combination. Additional positive effects were observed for biomarkers of lipid metabolism, beta-cell function, activity of the visceral adipose tissue, and chronic systemic inflammation.

Effects of pioglitazone and metformin fixed-dose combination therapy on cardiovascular risk markers of inflammation and lipid profile compared with pioglitazone and metformin monotherapy in patients with type 2 diabetes. [2010.12]
. Type 2 diabetes mellitus (T2DM) treatment should not increase cardiovascular (CV) risk and at best could provide benefit beyond lowering glucose... Thus, treatment with the FDC resulted in improved levels of CV biomarkers, which were better than or equal to monotherapy.

Efficacy and safety of pioglitazone/metformin fixed-dose combination therapy compared with pioglitazone and metformin monotherapy in treating patients with T2DM. [2009.12]
BACKGROUND: Studies have shown that many patients with type 2 diabetes do not achieve optimal glycemic control, and progression of diabetes over time requires more than one pharmacotherapy to achieve glycemic goal. OBJECTIVE: To examine the efficacy and safety of the fixed-dose combination (FDC) of pioglitazone 15 mg and metformin 850 mg versus its individual components in a twice-daily regimen over 24 weeks of treatment in type 2 diabetes patients who were currently not receiving antidiabetes therapy... CONCLUSIONS: Overall, treatment with pioglitazone/metformin FDC demonstrated greater efficacy than its individual components. The FDC therapy was well tolerated, with reduced or similar adverse event rates compared with each individual monotherapy.

Effects of pioglitazone and metformin fixed-dose combination therapy on cardiovascular risk markers of inflammation and lipid profile compared with pioglitazone and metformin monotherapy in patients with type 2 diabetes. [2010]
. Type 2 diabetes mellitus (T2DM) treatment should not increase cardiovascular (CV) risk and at best could provide benefit beyond lowering glucose... Thus, treatment with the FDC resulted in improved levels of CV biomarkers, which were better than or equal to monotherapy.

Combined pioglitazone and metformin treatment maintains the beneficial effect of short-term insulin infusion in patients with type 2 diabetes: results from a pilot study. [2009.11.01]
BACKGROUND: The aim of our study was to examine the efficacy of short-term intravenous insulin intervention followed by oral pioglitazone/metformin therapy to prevent patients from continuous insulin application... CONCLUSIONS: Our pilot study demonstrated that a beneficial effect of a short-term intravenous insulin application on glycemic control was effectively maintained by pioglitazone/metformin treatment for at least 4 months. In addition, the oral therapy significantly improved cardiovascular risk parameters.

Clinical Trials Related to Actoplus Met XR (Pioglitazone / Metformin)

Ovulation Induction in Women With Clomiphene Citrate Resistant PCOS [Not yet recruiting]
Polycystic ovary syndrome (PCOS) affects 5-10% of women in childbearing age. Hyperinsulinemia contributes to chronic anovulation commonly encountered in women with PCOS. The first choice therapy is clomiphene citrate (CC). In CC resistant cases, the American College of Obstetrics and Gynecology (ACOG) recommends the use of insulin sensitizer metformin. Other insulin sensitizing agents include rosiglitazone and pioglitazone. Pioglitazone is said to improve fertility and ovulation in patients with PCOS. CC may be associated with poor endometrial thickening due to its antiestrogenic effect. Letrozole may improve this condition. In this study we will compare the effect of combined letrozole-metformin-pioglitazone with that of combined CC-metformin-pioglitazone in ovulation induction in CC-resistant PCOS women.
