Description
DESCRIPTION Metformin hydrochloride extended release tablets USP is an oral antihyperglycemic drug used in the management of type 2 diabetes. Metformin hydrochloride ( N,N -dimethylimidodicar- bonimidic diamide hydrochloride) is not chemically or pharmacologically related to any other classes of oral antihyperglycemic agents. The structural formula is as shown: Metformin hydrochloride is a white to off-white crystalline compound with a molecular formula of C 4 H 11 N 5 • 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 pK a of metformin is 12.4. The pH of a 1% aqueous solution of metformin hydrochloride is 6.68. Metformin hydrochloride extended release tablets USP contain 500 mg of metformin hydrochloride USP as the active ingredient. Metformin hydrochloride extended release tablets USP 500 mg contain the inactive ingredients sodium carboxymethyl cellulose, hypromellose and magnesium stearate. Metformin hydrochloride extended release tablets USP 500 mg meets USP dissolution Test 3. System Components and Performance- Metformin hydrochloride extended release tablets USP comprises a swellable matrix system. In the aqueous gastrointestinal (GI) environment, the dosage form swells remarkably thereby increasing in size and geometry from where drug is released slowly by a process of diffusion through the gel matrix that is essentially independent of pH. The hydrated polymer system is not rigid and is expected to be broken up by normal peristalsis in the GI tract. The biologically inert components of the tablet may occasionally remain intact during GI transit and will be eliminated in the feces as a soft, hydrated mass. Structural Formula

Indications & Usage
INDICATIONS AND USAGE Metformin hydrochloride extended release tablets USP are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.
Dosage and Administration
DOSAGE AND ADMINISTRATION There is no fixed dosage regimen for the management of hyperglycemia in patients with type 2 diabetes with metformin hydrochloride extended release tablets USP or any other pharmacologic agent. Dosage of metformin hydrochloride extended release tablets USP must be individualized on the basis of both effectiveness and tolerance, while not exceeding the maximum recommended daily doses. The maximum recommended daily dose of metformin hydrochloride extended release tablets USP in adults is 2000 mg. Metformin hydrochloride extended release tablets USP should generally be given once daily with the evening meal. Metformin hydrochloride extended release tablets USP should be started at a low dose, with gradual dose escalation, both to reduce gastrointestinal side effects and to permit identification of the minimum dose required for adequate glycemic control of the patient. During treatment initiation and dose titration (see Recommended Dosing Schedule ), fasting plasma glucose should be used to determine the therapeutic response to metformin hydrochloride extended release tablets USP and identify the minimum effective dose for the patient. Thereafter, glycosylated hemoglobin should be measured at intervals of approximately three months. The therapeutic goal should be to decrease both fasting plasma glucose and glycosylated hemoglobin levels to normal or near normal by using the lowest effective dose of metformin hydrochloride extended release tablets USP, either when used as monotherapy or in combination with sulfonylurea or insulin. Monitoring of blood glucose and glycosylated hemoglobin will also permit detection of primary failure, i.e., inadequate lowering of blood glucose at the maximum recommended dose of medication, and secondary failure, i.e., loss of an adequate blood glucose lowering response after an initial period of effectiveness. Short-term administration of metformin hydrochloride extended release tablets USP may be sufficient during periods of transient loss of control in patients usually well-controlled on diet alone. Metformin hydrochloride extended release tablets USP must be swallowed whole and never crushed or chewed. Occasionally, the inactive ingredients of metformin hydrochloride extended release tablets USP will be eliminated in the feces as a soft, hydrated mass. (See Patient Information printed below.)
