How should I use GLIPIZIDE ER?
Glipizide extended-release tablets are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.
Section toggle-content closed
There is no fixed dosage regimen for the management of diabetes mellitus with glipizide extended-release tablets or any other hypoglycemic agent. Glycemic control should be monitored with hemoglobin A1C and/or blood-glucose levels to determine the minimum effective dose for the patient; to detect primary failure, i.e., inadequate lowering of blood glucose at the maximum recommended dose of medication; and to detect secondary failure, i.e., loss of an adequate blood-glucose-lowering response after an initial period of effectiveness. Home blood-glucose monitoring may also provide useful information to the patient and physician. Short-term administration of glipizide extended-release tablets may be sufficient during periods of transient loss of control in patients usually controlled on diet.
In general, glipizide extended-release tablets should be given with breakfast.
Recommended Dosing: The usual starting dose of glipizide extended-release tablets as initial therapy is 5 mg per day, given with breakfast. Those patients who may be more sensitive to hypoglycemic drugs may be started at a lower dose.
Dosage adjustment should be based on laboratory measures of glycemic control. While fasting blood-glucose levels generally reach steady-state following initiation or change in glipizide extended-release tablet dosage, a single fasting glucose determination may not accurately reflect the response to therapy. In most cases, hemoglobin A1C level measured at three month intervals is the preferred means of monitoring response to therapy.
Hemoglobin A1C should be measured as glipizide extended-release tablet therapy is initiated and repeated approximately three months later. If the result of this test suggests that glycemic control over the preceding three months was inadequate, the glipizide extended-release tablet dose may be increased. Subsequent dosage adjustments should be made on the basis of hemoglobin A1C levels measured at three month intervals. If no improvement is seen after three months of therapy with a higher dose, the previous dose should be resumed. Decisions which utilize fasting blood glucose to adjust glipizide extended-release tablet therapy should be based on at least two or more similar, consecutive values obtained seven days or more after the previous dose adjustment.
Most patients will be controlled with 5 mg to 10 mg taken once daily. However, some patients may require up to the maximum recommended daily dose of 20 mg. While the glycemic control of selected patients may improve with doses which exceed 10 mg, clinical studies conducted to date have not demonstrated an additional group average reduction of hemoglobin A1C beyond what was achieved with the 10 mg dose.
Based on the results of a randomized crossover study, patients receiving immediate release glipizide may be switched safely to glipizide extended-release tablets once-a-day at the nearest equivalent total daily dose. Patients receiving immediate release glipizide also may be titrated to the appropriate dose of glipizide extended-release tablets starting with 5 mg once daily. The decision to switch to the nearest equivalent dose or to titrate should be based on clinical judgment.
In elderly patients, debilitated or malnourished patients, and patients with impaired renal or hepatic function, the initial and maintenance dosing should be conservative to avoid hypoglycemic reactions (see section).
Combination Use: When adding other blood-glucose-lowering agents to glipizide extended-release tablets for combination therapy, the agent should be initiated at the lowest recommended dose, and patients should be observed carefully for hypoglycemia. Refer to the product information supplied with the oral agent for additional information.
When adding glipizide extended-release tablets to other blood-glucose-lowering agents, glipizide extended-release tablets can be initiated at 5 mg. Those patients who may be more sensitive to hypoglycemic drugs may be started at a lower dose. Titration should be based on clinical judgment.
When colesevelam is coadministered with glipizide ER, maximum plasma concentration and total exposure to glipizide is reduced. Therefore, glipizide ER should be administered at least 4 hours prior to colesevelam.
Patients Receiving Insulin: As with other sulfonylurea-class hypoglycemics, many patients with stable type 2 diabetes receiving insulin may be transferred safely to treatment with glipizide extended-release tablets. When transferring patients from insulin to glipizide extended-release tablets, the following general guidelines should be considered:
For patients whose daily insulin requirement is 20 units or less, insulin may be discontinued and glipizide extended-release tablet therapy may begin at usual dosages. Several days should elapse between titration steps.
For patients whose daily insulin requirement is greater than 20 units, the insulin dose should be reduced by 50% and glipizide extended-release tablet therapy may begin at usual dosages. Subsequent reductions in insulin dosage should depend on individual patient response. Several days should elapse between titration steps.
During the insulin withdrawal period, the patient should test urine samples for sugar and ketone bodies at least three times daily. Patients should be instructed to contact the prescriber immediately if these tests are abnormal. In some cases, especially when the patient has been receiving greater than 40 units of insulin daily, it may be advisable to consider hospitalization during the transition period.
Patients Receiving Other Oral Hypoglycemic Agents: As with other sulfonylurea-class hypoglycemics, no transition period is necessary when transferring patients to glipizide extended-release tablets. Patients should be observed carefully (1 to 2 weeks) for hypoglycemia when being transferred from longer half-life sulfonylureas (e.g., chlorpropamide) to glipizide extended-release tablets due to potential overlapping of drug effect.

What should I look out for while using GLIPIZIDE ER?
Glipizide extended-release tablets are contraindicated in patients with:
1.Known hypersensitivity to glipizide or any excipients in the tablets.
2.Type 1 diabetes mellitus, diabetic ketoacidosis, with or without coma. This condition should be treated with insulin.
What might happen if I take too much GLIPIZIDE ER?
There is no well-documented experience with glipizide extended-release tablets overdosage in humans. There have been no known suicide attempts associated with purposeful overdosing with glipizide extended-release tablets. In nonclinical studies the acute oral toxicity of glipizide was extremely low in all species tested (LD50 greater than 4 g/kg). Overdosage of sulfonylureas including glipizide can produce hypoglycemia. Mild hypoglycemic symptoms without loss of consciousness or neurologic findings should be treated aggressively with oral glucose and adjustments in drug dosage and/or meal patterns. Close monitoring should continue until the physician is assured that the patient is out of danger. Severe hypoglycemic reactions with coma, seizure, or other neurological impairment occur infrequently, but constitute medical emergencies requiring immediate hospitalization. If hypoglycemic coma is diagnosed or suspected, the patient should be given rapid intravenous injection of concentrated (50%) glucose solution. This should be followed by a continuous infusion of a more dilute (10%) glucose solution at a rate that will maintain the blood glucose at a level above 100 mg/dL. Patients should be closely monitored for a minimum of 24 to 48 hours since hypoglycemia may recur after apparent clinical recovery. Clearance of glipizide from plasma may be prolonged in persons with liver disease. Because of the extensive protein binding of glipizide, dialysis is unlikely to be of benefit.

Glipizide extended-release tablets are contraindicated in patients with:1.Known hypersensitivity to glipizide or any excipients in the tablets.
2.Type 1 diabetes mellitus, diabetic ketoacidosis, with or without coma. This condition should be treated with insulin.
The vasodilating effects of isosorbide dinitrate may be additive with those of other vasodilators. Alcohol, in particular, has been found to exhibit additive effects of this variety.
Concomitant use of isosorbide dinitrate with phosphodiesterase inhibitors in any form is contraindicated (see ).
Concomitant use of isosorbide dinitrate with riociguat, a soluble guanylate cyclase stimulator, is contraindicated (see ).

In U.S. controlled studies the frequency of serious adverse experiences reported was very low and causal relationship has not been established.
The 580 patients from 31 to 87 years of age who received glipizide extended-release tablets in doses from 5 mg to 60 mg in both controlled and open trials were included in the evaluation of adverse experiences. All adverse experiences reported were tabulated independently of their possible causal relation to medication.
Hypoglycemia: See and sections.
Only 3.4% of patients receiving glipizide extended-release tablets had hypoglycemia documented by a blood-glucose measurement <60 mg/dL and/or symptoms believed to be associated with hypoglycemia. In a comparative efficacy study of glipizide extended-release tablets and glipizide tablets, hypoglycemia occurred rarely with an incidence of less than 1% with both drugs.
In double-blind, placebo-controlled studies the adverse experiences reported with an incidence of 3% or more in glipizide extended-release tablet-treated patients include:
The following adverse experiences occurred with an incidence of less than 3% in glipizide extended-release tablet-treated patients:
Body as a whole–pain Nervous system–insomnia, paresthesia, anxiety, depression and hypesthesia Gastrointestinal–nausea, dyspepsia, constipation and vomiting Metabolic–hypoglycemia Musculoskeletal–arthralgia, leg cramps and myalgia Cardiovascular–syncope Skin–sweating and pruritus Respiratory–rhinitis Special senses–blurred vision Urogenital–polyuria
Other adverse experiences occurred with an incidence of less than 1% in glipizide extended-release tablet-treated patients:
Body as a whole–chills Nervous system–hypertonia, confusion, vertigo, somnolence, gait abnormality and decreased libido Gastrointestinal–anorexia and trace blood in stool Metabolic–thirst and edema Cardiovascular–arrhythmia, migraine, flushing and hypertension Skin–rash and urticaria Respiratory–pharyngitis and dyspnea Special senses–pain in the eye, conjunctivitis and retinal hemorrhage Urogenital–dysuria
Although these adverse experiences occurred in patients treated with glipizide extended-release tablets, a causal relationship to the medication has not been established in all cases.
There have been rare reports of gastrointestinal irritation and gastrointestinal bleeding with use of another drug in this non-deformable sustained release formulation, although causal relationship to the drug is uncertain.
Postmarketing Experience
The following adverse events have been reported in postmarketing surveillance:
Gastrointestinal: abdominal pain
Hepatobiliary: Cholestatic and hepatocellular forms of liver injury accompanied by jaundice have been reported rarely in association with glipizide; glipizide extended-release tablets should be discontinued if this occurs.
The following are adverse experiences reported with immediate release glipizide and other sulfonylureas, but have not been observed with glipizide extended-release tablets:
Hematologic: Leukopenia, agranulocytosis, thrombocytopenia, hemolytic anemia (see ), aplastic anemia and pancytopenia have been reported with sulfonylureas.
Metabolic: Hepatic porphyria and disulfiram-like reactions have been reported with sulfonylureas. In the mouse, glipizide pretreatment did not cause an accumulation of acetaldehyde after ethanol administration. Clinical experience to date has shown that glipizide has an extremely low incidence of disulfiram-like alcohol reactions.
Endocrine Reactions: Cases of hyponatremia and the syndrome of inappropriate antidiuretic hormone (SIADH) secretion have been reported with glipizide and other sulfonylureas.
Laboratory Tests: The pattern of laboratory test abnormalities observed with glipizide was similar to that for other sulfonylureas. Occasional mild to moderate elevations of SGOT, LDH, alkaline phosphatase, BUN and creatinine were noted. One case of jaundice was reported. The relationship of these abnormalities to glipizide is uncertain, and they have rarely been associated with clinical symptoms.
