Side Effects & Adverse Reactions
Metformin Hydrochloride
Lactic acidosis:
Lactic acidosis is a rare, but serious, metabolic complication that can occur due to metformin accumulation during treatment with Glipizide and Metformin HCl Tablets; when it occurs, it is fatal in approximately 50% of cases. Lactic acidosis may also occur in association with a number of pathophysiologic conditions, including diabetes mellitus, and whenever there is significant tissue hypoperfusion and hypoxemia. Lactic acidosis is characterized by elevated blood lactate levels (>5 mmol/L), decreased blood pH, electrolyte disturbances with an increased anion gap, and an increased lactate/pyruvate ratio. When metformin is implicated as the cause of lactic acidosis, metformin plasma levels >5 μg/mL are generally found.
The reported incidence of lactic acidosis in patients receiving Metformin hydrochloride is very low (approximately 0.03 cases/1000 patient-years, with approximately 0.015 fatal cases/1000 patient-years). In more than 20,000 patient-years exposure to metformin in clinical trials, there were no reports of lactic acidosis. Reported cases have occurred primarily in diabetic patients with significant renal insufficiency, including both intrinsic renal disease and renal
hypoperfusion, often in the setting of multiple concomitant medical/surgical problems and multiple concomitant medications.
Patients with congestive heart failure requiring pharmacologic management, in particular those with unstable or acute congestive heart failure who are at risk of hypoperfusion and hypoxemia, are at increased risk of lactic acidosis. The risk of lactic acidosis increases with the degree of renal dysfunction and the patient's age. The risk of lactic acidosis may, therefore, be significantly decreased by regular monitoring of renal function in patients taking metformin and by use of the minimum effective dose of metformin. In particular, treatment of the elderly should be accompanied by careful monitoring of renal function. Glipizide and Metformin HCl Tablets treatment should not be initiated in patients ≥80 years of age unless measurement of creatinine clearance demonstrates that renal function is not reduced, as these patients are more susceptible to developing lactic acidosis. In addition, Glipizide and Metformin HCl Tablets should be promptly withheld in the presence of any condition associated with hypoxemia, dehydration, or sepsis. Because impaired hepatic function may significantly limit the ability to clear lactate, Glipizide and Metformin HCl Tablets should generally be avoided in patients with clinical or laboratory evidence of hepatic disease. Patients should be cautioned against excessive alcohol intake, either acute or chronic, when taking Glipizide and Metformin HCl Tablets, since alcohol potentiates the effects of metformin hydrochloride on lactate metabolism. In addition, Glipizide and Metformin HCl Tablets should be temporarily discontinued prior to any intravascular radiocontrast study and for any surgical procedure (see also PRECAUTIONS).
The onset of lactic acidosis often is subtle, and accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, increasing somnolence, and nonspecific abdominal distress. There may be associated hypothermia, hypotension, and resistant bradyarrhythmias with more marked acidosis. The patient and the patient's physician must be aware of the possible importance of such symptoms and the patient should be instructed to notify the physician immediately if they occur (see also PRECAUTIONS). Glipizide and Metformin HCl Tablets should be withdrawn until the situation is clarified. Serum electrolytes, ketones, blood glucose, and if indicated, blood pH, lactate levels, and even blood metformin levels may be useful. Once a patient is stabilized on any dose level of Glipizide and Metformin HCl Tablets, gastrointestinal symptoms, which are common during initiation of therapy with metformin, are unlikely to be drug related. Later occurrence of gastrointestinal symptoms could be due to lactic acidosis or other serious disease.
Levels of fasting venous plasma lactate above the upper limit of normal but less than 5 mmol/L in patients taking Glipizide and Metformin HCl Tablets do not necessarily indicate impending lactic acidosis and may be explainable by other mechanisms, such as poorly controlled diabetes or obesity, vigorous physical activity, or technical problems in sample handling. (See also PRECAUTIONS.)
Lactic acidosis should be suspected in any diabetic patient with metabolic acidosis lacking evidence of ketoacidosis (ketonuria and ketonemia).
Lactic acidosis is a medical emergency that must be treated in a hospital setting. In a patient with lactic acidosis who is taking Glipizide and Metformin HCl Tablets, the drug should be discontinued immediately and general supportive measures promptly instituted. Because metformin hydrochloride is dialyzable (with a clearance of up to 170 mL/min under good hemodynamic conditions), prompt hemodialysis is recommended to correct the acidosis and remove the accumulated metformin. Such management often results in prompt reversal of symptoms and recovery. (See also CONTRAINDICATIONS and PRECAUTIONS.)

Other Information
Glipizide and Metformin HCl Tablets contain two oral antihyperglycemic drugs used in the management of type 2 diabetes, Glipizide and Metformin Hydrochloride.
Glipizide is an oral antihyperglycemic drug of the sulfonylurea class. The chemical name for Glipizide is 1-cyclohexyl-3-[[p-[2-(5-methylpyrazinecarboxamido)ethyl]phenyl] sulfonyl]urea. Glipizide is a whitish, odorless powder with a molecular formula of C21H27N5O4S, a molecular weight of 445.55 and a pKa of 5.9. It is insoluble in water and alcohols, but soluble in 0.1 N NaOH; it is freely soluble in dimethylformamide. The structural formula is represented below.
Glipizide
Metformin hydrochloride is an oral antihyperglycemic drug used in the management of type 2 diabetes. Metformin hydrochloride (N,N-dimethylimidodicarbonimidic diamide monohydrochloride) is not chemically or pharmacologically related to sulfonylureas, thiazolidinediones, or α-glucosidase inhibitors. It is a white to off-white crystalline compound with a molecular formula of C4H12ClN5 (monohydrochloride) 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:
Metformin Hydrochloride
Glipizide and Metformin HCl Tablets is available for oral administration in tablets containing 2.5 mg Glipizide with 250 mg Metformin Hydrochloride, 2.5 mg Glipizide with 500 mg Metformin Hydrochloride, and 5 mg Glipizide with 500 mg Metformin Hydrochloride. In addition, each tablet contains the following inactive ingredients: Sodium Starch Glycolate, Corn Starch, Povidone, Magnesium Stearate, Colloidal Silicon Dioxide, Hypromellose, Talc, Titanium Dioxide, Polyethylene Glycol 6000, Propylene Glycol and Iron Oxide Red. The tablets are film coated, which provides color differentiation.

General Considerations
Dosage of Glipizide and Metformin HCl Tablets must be individualized on the basis of both effectiveness and tolerance while not exceeding the maximum recommended daily dose of 20 mg glipizide/2000 mg metformin. Glipizide and Metformin HCl Tablets should be given with meals and should be initiated at a low dose, with gradual dose escalation as described below, in order to avoid hypoglycemia (largely due to glipizide), to reduce GI side effects (largely due to metformin), and to permit determination of the minimum effective dose for adequate control of blood glucose for the individual patient.
With initial treatment and during dose titration, appropriate blood glucose monitoring should be used to determine the therapeutic response to Glipizide and Metformin HCl Tablets and to identify the minimum effective dose for the patient. Thereafter, HbA1c should be measured at intervals of approximately 3 months to assess the effectiveness of therapy. The therapeutic goal in all patients with type 2 diabetes is to decrease FPG, PPG, and HbA1c to normal or as near normal as possible. Ideally, the response to therapy should be evaluated using HbA1c (glycosylated hemoglobin), which is a better indicator of longterm glycemic control than FPG alone.
No studies have been performed specifically examining the safety and efficacy of switching to Glipizide and Metformin HCl Tablets therapy in patients taking concomitant glipizide (or other sulfonylurea) plus metformin. Changes in glycemic control may occur in such patients, with either hyperglycemia or hypoglycemia possible. Any change in therapy of type 2 diabetes should be undertaken with care and appropriate monitoring.
When colesevelam is coadministered with glipizide ER, maximum plasma concentration and total exposure to glipizide is reduced. Therefore, Glipizide and Metformin HCl Tablets should be administered at least 4 hours prior to colesevelam.
Glipizide and Metformin HCl Tablets in Patients with Inadequate Glycemic Control on Diet and Exercise Alone
For patients with type 2 diabetes whose hyperglycemia cannot be satisfactorily managed with diet and exercise alone, the recommended starting dose of Glipizide and Metformin HCl Tablets is 2.5 mg/250 mg once a day with a meal. For patients whose FPG is 280 mg/dL to 320 mg/dL a starting dose of Glipizide and Metformin HCl Tablets 2.5 mg/500 mg twice daily should be considered. The efficacy of Glipizide and Metformin HCl Tablets in patients whose FPG exceeds 320 mg/dL has not been established. Dosage increases to achieve adequate glycemic control should be made in increments of one tablet per day every two weeks up to maximum of 10 mg/1000 mg or 10 mg/2000 mg Glipizide and Metformin HCl Tablets per day given in divided doses. In clinical trials of Glipizide and Metformin HCl Tablets as initial therapy, there was no experience with total daily doses greater than 10 mg/2000 mg per day.
Glipizide and Metformin HCl Tablets in Patients with Inadequate Glycemic Control on a Sulfonylurea and/or Metformin
For patients not adequately controlled on either glipizide (or another sulfonylurea) or metformin alone, the recommended starting dose of Glipizide and Metformin HCl Tablets is 2.5 mg/500 mg or 5 mg/500 mg twice daily with the morning and evening meals. In order to avoid hypoglycemia, the starting dose of Glipizide and Metformin HCl Tablets should not exceed the daily doses of Glipizide or metformin already being taken. The daily dose should be titrated in increments of no more than 5 mg/500 mg up to the minimum effective dose to achieve adequate control of blood glucose or to a maximum dose of 20 mg/2000 mg per day.
Patients previously treated with combination therapy of glipizide (or another sulfonylurea) plus metformin may be switched to Glipizide and Metformin HCl Tablets 2.5 mg/500 mg or 5 mg/500 mg; the starting dose should not exceed the daily dose of Glipizide (or equivalent dose of another sulfonylurea) and metformin already being taken. The decision to switch to the nearest equivalent dose or to titrate should be based on clinical judgment. Patients should be monitored closely for signs and symptoms of hypoglycemia following such a switch and the dose of Glipizide and Metformin HCl Tablets should be titrated as described above to achieve adequate control of blood glucose.
Specific Patient Populations
Glipizide and Metformin HCl Tablets is not recommended for use during pregnancy or for use in pediatric patients. The initial and maintenance dosing of Glipizide and Metformin HCl Tablets should be conservative in patients with advanced age, due to the potential for decreased renal function in this population. Any dosage adjustment requires a careful assessment of renal function. Generally, elderly, debilitated, and malnourished patients should not be titrated to the maximum dose of Glipizide and Metformin HCl Tablets to avoid the risk of hypoglycemia. Monitoring of renal function is necessary to aid in prevention of metformin-associated lactic acidosis, particularly in the elderly. (See WARNINGS.)
