2 DOSAGE AND ADMINISTRATION Important Dosing Information ( 2.1 ) Glycopyrrolate tablets 2 mg are not recommended for patients initiating treatment or receiving maintenance treatment with glycopyrrolate tablets 1 mg or another 1 mg dosage strength of oral glycopyrrolate tablets. Recommended Dosage ( 2.2 ) The recommended initial dosage of glycopyrrolate tablets 1 mg is 1 mg three times daily (in the morning, early afternoon, and at bedtime). Some patients may require 2 mg at bedtime to assure overnight control of symptoms. For maintenance, a dosage of 1 mg twice a day is frequently adequate. The recommended dosage of glycopyrrolate tablets 2 mg for adults is 2 mg two or three times daily at equally spaced intervals. The maximum recommended daily dosage is 8 mg. Use the lowest effective dosage of glycopyrrolate to control symptoms. If patients can be titrated to a lower dose, switch from glycopyrrolate tablets 2 mg to glycopyrrolate tablets 1 mg or another 1 mg oral tablet of glycopyrrolate. 2.1 Important Dosing Information Glycopyrrolate tablets 2 mg are not recommended for patients in whom a lower dosage strength of oral glycopyrrolate (e.g., glycopyrrolate tablets 1 mg or another 1 mg tablet strength) is appropriate for initial or maintenance treatment because the dosage strength of glycopyrrolate tablets may exceed the recommended initial and maintenance dosage of oral glycopyrrolate tablets. 2.2 Recommended Dosage The recommended initial dosage of glycopyrrolate tablets 1 mg for adults is 1 mg three times daily (in the morning, early afternoon, and at bedtime). Some patients may require 2 mg at bedtime to assure overnight control of symptoms. For maintenance, a dosage of 1 mg twice a day is frequently adequate. The recommended dosage of glycopyrrolate tablets 2 mg for adults is 2 mg two or three times daily at equally spaced intervals. The maximum recommended daily dosage of glycopyrrolate is 8 mg. Use the lowest effective dosage of glycopyrrolate to control symptoms. If patients can be titrated to a lower dose, switch from glycopyrrolate tablets 2 mg to glycopyrrolate tablets 1 mg or another 1 mg oral tablet of glycopyrrolate.

1 INDICATIONS AND USAGE Glycopyrrolate tablets are indicated in adults to reduce symptoms of a peptic ulcer as an adjunct to treatment of peptic ulcer. Limitations of Use Glycopyrrolate tablets are not indicated as monotherapy for the treatment of peptic ulcer because effectiveness in peptic ulcer healing has not been established. Glycopyrrolate tablets are anticholinergics indicated in adults to reduce symptoms of a peptic ulcer as an adjunct to treatment of peptic ulcer. ( 1 ) Limitations of Use: Not indicated as monotherapy for the treatment of peptic ulcer because effectiveness in peptic ulcer healing has not been established. ( 1 )

10 OVERDOSAGE Signs and symptoms of glycopyrrolate overdosage are related to excessive anti-muscarinic anticholinergic activity and are generally peripheral (e.g., flushing, hyperthermia, tachycardia, ileus, urinary retention, loss of ocular accommodation, and light sensitivity due to mydriasis), but central nervous system toxicity (agitation, seizures, hyperthermia) may also occur. If over-exposure occurs, call the Poison Control Center at 1-800-222-1222 for current information on the management of glycopyrrolate poisoning and overdosage. Management of glycopyrrolate overdosage is based upon presenting signs and symptoms, including close observation for severe or life-threatening complications which may require respiratory and cardiovascular monitoring and support. Consider administration of activated charcoal and/or use of a reversible anticholinesterase as appropriate or recommended by Poison Control.

7 DRUG INTERACTIONS Other Anticholinergic Drugs : Concomitant use is not recommended. ( 5.3 , 5.4 , 5.6 , 7.1 ) Drugs with Altered Absorption due to Decreased GI Motility : Concomitant use is not recommended. ( 7.2 ) GI Toxicity with Solid Oral Dosage Forms of Potassium Chloride : Concomitant use is not recommended. ( 7.3 ) 7.1 Other Anticholinergic Drugs There is potential for an additive interaction between glycopyrrolate and concomitantly used anticholinergic drugs (e.g., tricyclic antidepressants, anti-epileptics, class I antiarrhythmics, anti-spasmodics, amantadine) resulting in increased anticholinergic adverse reactions. Coadministration of antipsychotics with glycopyrrolate may lead to worsening of tardive dyskinesia. Glycopyrrolate is not recommended in patients taking other anticholinergic drugs [see Warnings and Precautions (5.3 , 5.4 , 5.6) ] . 7.2 Drugs with Altered Absorption due to Decreased Gastrointestinal Motility and Increased Transit Time Decreased gastrointestinal motility by glycopyrrolate may impact absorption of other drugs leading toincreased or decreased drug exposure. Glycopyrrolate is not recommended in patients taking other drugs that are affected by altered gastrointestinal motility [see Warnings and Precautions (5.3) ] . 7.3 Gastrointestinal Toxicity with Solid Dosage Forms of Potassium Chloride Oral glycopyrrolate may worsen gastrointestinal mucosal injury reported with solid oral dosage forms of potassium chloride due to decreased gastric motility and increased transit time, leading to prolonged contact with the gastrointestinal mucosa. Glycopyrrolate is not recommended in patients taking solid oral dosage forms of potassium chloride.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Glycopyrrolate, an anticholinergic (antimuscarinic) agent, inhibits the action of acetylcholine on parietal cells in the stomach and decreases the volume and acidity of gastric secretions. 12.2 Pharmacodynamics No formal pharmacodynamic studies have been conducted with glycopyrrolate. 12.3 Pharmacokinetics Patients with Renal Impairment In the published literature, glycopyrrolate 4 mcg/kg was administered intravenously (glycopyrrolate tablets are not recommended for intravenous use) in uremic patients undergoing renal transplantation surgery. The mean AUC (10.6 mcg·h/L) and 24-hour urinary excretion (7%) for glycopyrrolate were significantly different from normal healthy adult subjects undergoing general surgery (3.7 mcg·h/L, and 65%, respectively) [see Use in Specific Populations (8.6) ] .

8.5 Geriatric Use Geriatric patients 65 years of age and older may be more sensitive to the anticholinergic adverse reactions of glycopyrrolate leading to complications of urinary retention, bowel obstruction, heat prostration, arrhythmias, delirium, and falls or fractures; therefore, glycopyrrolate is not recommended in geriatric patients and may be contraindicated in some geriatric patients with underlying medical conditions [see Contraindications (4) and Warnings and Precautions (5) ] .

8.2 Lactation Risk Summary There are no data on the presence of glycopyrrolate in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. As with other anticholinergic drugs, glycopyrrolate may cause suppression of lactation. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for glycopyrrolate and any potential adverse effects on the breastfed infant from glycopyrrolate.

8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established.

8.1 Pregnancy Risk Summary Over decades of use, there is an absence of published data on orally administered glycopyrrolate in pregnant women, including an absence of any reports of a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In animal studies, at non-maternally toxic doses of oral glycopyrrolate, there were no adverse developmental effects in rats or rabbits. A pre- and post-natal development study of oral glycopyrrolate in rats showed a decrease in pup mean bodyweight that recovered post nursing, with no other developmental effects observed (see Data) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data At non-maternally toxic doses of oral glycopyrrolate, there were no effects on embryo-fetal development or toxicity in rats or rabbits. A pre- and post-natal development study of oral glycopyrrolate in rats showed a decrease in pup mean bodyweight that recovered post nursing, with no other developmental effects observed. In a published reproductive and developmental study, male and female rats were administered glycopyrrolate in the diet at 0 mg/kg/day, 32.5 mg/kg/day, 63 mg/kg/day, and 130 mg/kg/day for 3 weeks to 5 weeks and through up to three consecutive litters. There was no indication of abnormalities in the pups of treated dams. There was a decreased rate of conception and in survival rate at weaning for all treated animals in a dose-related manner. Diminished rates of conception may be due to diminished seminal secretion [see Nonclinical Toxicology (13.1) ] .
