CONGESTIVE HEART FAILURE
- Thiazolidinediones, including pioglitazone, which is a component of ACTOPLUS MET, cause or exacerbate congestive heart failure in some patients (see WARNINGS, Pioglitazone hydrochloride). After initiation of ACTOPLUS MET, 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 must be considered.
- ACTOPLUS MET is not recommended in patients with symptomatic heart failure. Initiation of ACTOPLUS MET in patients with established NYHA Class III or IV heart failure is contraindicated (see CONTRAINDICATIONS and WARNINGS, Pioglitazone hydrochloride).
ACTOPLUS MET® (pioglitazone hydrochloride and metformin hydrochloride) tablets contain two oral antihyperglycemic drugs used in the management of type 2 diabetes: pioglitazone hydrochloride and metformin hydrochloride. The concomitant use of pioglitazone and metformin has been previously approved based on clinical trials in patients with type 2 diabetes inadequately controlled on metformin. Additional efficacy and safety information about pioglitazone and metformin monotherapies may be found in the prescribing information for each individual drug.
Pioglitazone hydrochloride is an oral antihyperglycemic agent that acts primarily by decreasing insulin resistance. Pioglitazone is used in the management of type 2 diabetes. Pharmacological studies indicate that pioglitazone improves sensitivity to insulin in muscle and adipose tissue and inhibits hepatic gluconeogenesis. Pioglitazone improves glycemic control while reducing circulating insulin levels.
Pioglitazone [(±)-5-[[4-[2-(5-ethyl-2-pyridinyl)ethoxy]phenyl]methyl]-2,4-] thiazolidinedione monohydrochloride belongs to a different chemical class and has a different pharmacological action than the sulfonylureas, biguanides, or the α-glucosidase inhibitors. The molecule contains one asymmetric center, and the synthetic compound is a racemate. The two enantiomers of pioglitazone interconvert in vivo. The structural formula is as shown:
Pioglitazone hydrochloride is an odorless white crystalline powder that has a molecular formula of C19H20N2O3S•HCl and a molecular weight of 392.90. It is soluble in N,N dimethylformamide, slightly soluble in anhydrous ethanol, very slightly soluble in acetone and acetonitrile, practically insoluble in water, and insoluble in ether.
Metformin hydrochloride (N,N -dimethylimidodicarbonimidic diamide hydrochloride) is not chemically or pharmacologically related to any other classes of oral antihyperglycemic agents. Metformin hydrochloride is a white crystalline powder with a molecular formula of C4H11N5•HCl and a molecular weight of 165.62. Metformin hydrochloride is freely soluble in water and is practically insoluble in acetone, ether, and chloroform. The pKa of metformin is 12.4. The pH of a 1% aqueous solution of metformin hydrochloride is 6.68. The structural formula is as shown:
ACTOPLUS MET is available as a tablet for oral administration containing 15 mg pioglitazone hydrochloride (as the base) with 500 mg metformin hydrochloride (15 mg/500 mg) or 15 mg pioglitazone hydrochloride (as the base) with 850 mg metformin hydrochloride (15 mg/850 mg) formulated with the following excipients: povidone USP, microcrystalline cellulose NF, croscarmellose sodium NF, magnesium stearate NF, hypromellose 2910 USP, polyethylene glycol 8000 NF, titanium dioxide USP, and talc USP.
