"The U.S. Food and Drug Administration today approved three new related products for use with diet and exercise to improve blood sugar control in adults with type 2 diabetes: Nesina (alogliptin) tablets, Kazano (alogliptin and metformin hydrochlor"...
(linagliptin and metformin hydrochloride)
RISK OF LACTIC ACIDOSIS
Lactic acidosis is a rare, but serious, complication that can occur due to metformin accumulation. The risk increases with conditions such as renal impairment, sepsis, dehydration, excess alcohol intake, hepatic 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, JENTADUETO should be discontinued and the patient hospitalized immediately. [See WARNINGS AND PRECAUTIONS.]
JENTADUETO tablets contain 2 oral antihyperglycemic drugs used in the management of type 2 diabetes mellitus: linagliptin and metformin hydrochloride.
Linagliptin is an orally-active inhibitor of the dipeptidyl peptidase-4 (DPP-4) enzyme.
Linagliptin is described chemically as 1H-Purine-2,6-dione, 8-[(3R)-3-amino-1-piperidinyl]-7-(2-butyn-1-yl)-3,7-dihydro-3-methyl-1-[(4-methyl-2quinazolinyl)methyl]-
The empirical formula is C25H28N8O2 and the molecular weight is 472.54 g/mol. The structural formula is:
Linagliptin is a white to yellowish, not or only slightly hygroscopic solid substance. It is very slightly soluble in water (0.9 mg/mL). Linagliptin is soluble in methanol (ca. 60 mg/mL), sparingly soluble in ethanol (ca. 10 mg/mL), very slightly soluble in isopropanol ( < 1 mg/mL), and very slightly soluble in acetone (ca. 1 mg/mL).
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 to off-white crystalline compound with a molecular formula of C4H11N5•HCl and a molecular weight of 165.63. 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:
JENTADUETO is available for oral administration as tablets containing 2.5 mg linagliptin and 500 mg metformin hydrochloride (JENTADUETO 2.5 mg/500 mg), 850 mg metformin hydrochloride (JENTADUETO 2.5 mg/850 mg) or 1000 mg metformin hydrochloride (JENTADUETO 2.5 mg/1000 mg). Each film-coated tablet of JENTADUETO contains the following inactive ingredients: arginine, corn starch, copovidone, colloidal silicon dioxide, magnesium stearate, titanium dioxide, propylene glycol, hypromellose, talc, yellow ferric oxide (2.5 mg/500 mg; 2.5 mg/850 mg) and/or red ferric oxide (2.5 mg/850 mg; 2.5 mg/1000 mg).
