KAZANO
(alogliptin and metformin HCl) Tablets

WARNING

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 impairment, renal impairment, and acute congestive heart failure [see WARNINGS AND PRECAUTIONS].
  • 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. [see WARNINGS AND PRECAUTIONS]
  • If acidosis is suspected, KAZANO (alogliptin and metformin HCl) should be discontinued and the patient hospitalized immediately. [see WARNINGS AND PRECAUTIONS]

DRUG DESCRIPTION

KAZANO tablets contain 2 oral antihyperglycemic drugs used in the management of type 2 diabetes: alogliptin and metformin hydrochloride.

Alogliptin

Alogliptin is a selective, orally bioavailable inhibitor of the enzymatic activity of dipeptidyl peptidase-4 (DPP-4). Chemically, alogliptin is prepared as a benzoate salt, which is identified as 2-({6-[(3R)-3-aminopiperidin-1-yl]-3-methyl-2,4-dioxo-3,4-dihydropyrimidin- 1(2H)-yl}methyi)benzonitrile monobenzoate. It has a molecular formula of C18H21N5O2•C7H6O2 and a molecular weight of 461.51 daltons; the structural formula is:

Alogliptin Structural Formula Illustration

Alogliptin benzoate is a white to off-white, crystalline powder, containing one asymmetric carbon in the aminopiperidine moiety. It is soluble in dimethylsulfoxide, sparingly soluble in water and methanol, slightly soluble in ethanol, and very slightly soluble in octanol and isopropyl acetate.

Metformin hydrochloride

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 C4H11 N5•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 as shown:
