Glycopyrrolate

Important Dosing Information (2.1)

• Glycopyrrolate is not recommended for patients initiating treatment or receiving maintenance treatment with glycopyrrolate or another 1 mg dosage strength of oral glycopyrrolate tablets. Recommended Dosage (2.2)
• The recommended initial dosage of glycopyrrolate 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 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 or another 1 mg oral tablet of glycopyrrolate. 2.1 Important Dosing Information
• Glycopyrrolate is not recommended for patients in whom a lower dosage strength of oral glycopyrrolate (e.g., glycopyrrolate or another 1 mg tablet strength) is appropriate for initial or maintenance treatment because the dosage strength of glycopyrrolate may exceed the recommended initial and maintenance dosage of oral glycopyrrolate tablets. 2.2 Recommended Dosage
• The recommended initial dosage of glycopyrrolate 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 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 or another 1 mg oral tablet of glycopyrrolate.

• Precipitation of Acute Glaucoma: May increase intraocular pressure; if symptoms occur, discontinue use and promptly seek medical care. (4, 5.1)
• Partial or Complete Mechanical Intestinal Obstruction: Diarrhea may be an early symptom, especially in patients with ileostomy or colostomy. If the obstruction is suspected, discontinue use and evaluate the patient for obstruction. (4, 5.2)
• GI Adverse Reactions Due to Decreased GI Motility: Delayed gastric emptying, constipation, and intestinal pseudo-obstruction may occur and precipitate or aggravate paralytic ileus and toxic megacolon; not recommended for use with anticholinergics or other medications that decrease GI peristalsis. (4, 5.3, 7.1)
• Cognitive and Visual Adverse Reactions: May impair mental and/or physical function. Inform patients not to operate motor vehicles or perform other hazardous tasks until reasonably certain they are not adversely affected; discontinue use if signs or symptoms develop. (5.4, 7.1)
• Heat Prostration at High Environmental Temperatures: Heat prostration resulting in fever and heatstroke can occur, especially in geriatric patients. Avoid exposure to hot or very warm environmental temperatures. (5.5, 5.7)
• Other Conditions Exacerbated by Anticholinergic Adverse Reactions: Use is not recommended in patients with autonomic neuropathy, hyperthyroidism, cardiac disease, hiatal hernia, etc. (5.6, 7.1)
• Increased Risk of Anticholinergic Adverse Reactions in Geriatric Patients: Complications include urinary retention, bowel obstruction, heat prostration, arrhythmias, delirium, and falls or fractures. Not recommended in geriatric patients and may be contraindicated in some patients with underlying medical conditions. (4, 5.7, 8.5)

5.1Precipitation of Acute Glaucoma

Glycopyrrolate may cause increased intraocular pressure in patients with glaucoma and reduce the effects of antiglaucoma agents. Instruct patients to discontinue glycopyrrolate and promptly seek medical care if they experience symptoms of acute angle-closure glaucoma (pain and reddening of the eyes accompanied by dilated pupils) [see Contraindications (4)]. 5.2 Partial or Complete Mechanical Intestinal Obstruction Glycopyrrolate may worsen intestinal mechanical obstruction, and diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. If partial or complete intestinal obstruction is suspected, discontinue the use of glycopyrrolate and evaluate for potential intestinal obstruction [see Contraindications (4)]. 5.3 Gastrointestinal Adverse Reactions Due to Decreased Gastrointestinal Motility Glycopyrrolate reduces gastrointestinal motility and may result in delayed gastric emptying, constipation, and intestinal pseudo-obstruction and may precipitate or aggravate paralytic ileus and toxic megacolon [see Contraindications (4)]. The risk of gastrointestinal adverse reactions is further increased with the use of other anticholinergics and other medications that decrease gastrointestinal peristalsis. Monitor patients for symptoms of decreased gastrointestinal motility. Concomitant use of glycopyrrolate and other anticholinergics or other medications that decrease GI peristalsis is not recommended [see Drug Interactions (7.2)]. 5.4 Cognitive and Visual Adverse Reactions Glycopyrrolate may produce drowsiness and blurred vision and impair the mental and/or physical abilities required for the performance of hazardous tasks such as driving a motor vehicle, operating machinery, or performing other hazardous work [see Adverse Reactions (6)]. Concomitant use of other drugs that have anticholinergic properties may increase these effects [see Drug Interactions (7.1)]. Inform patients not to operate motor vehicles or other dangerous machinery or perform other hazardous tasks until they are reasonably certain that glycopyrrolate does not affect them adversely. Discontinue glycopyrrolate if signs or symptoms of cognitive or visual impairment develop. 5.5 Heat Prostration at High Environmental Temperatures In the presence of a high environmental temperature, heat prostration resulting in fever and heatstroke can occur with the use of glycopyrrolate due to decreased sweating, particularly in geriatric patients [see Adverse Reactions (6)]. Advise patients to avoid exposure to hot or very warm environmental temperatures when taking glycopyrrolate. Glycopyrrolate are not recommended in geriatric patients [see Warnings and Precautions (5.7)]. 5.6 Other Conditions Exacerbated by Anticholinergic Adverse Reactions Glycopyrrolate are not recommended in patients with other conditions exacerbated by anticholinergic adverse reactions (e.g., autonomic neuropathy, hyperthyroidism, cardiac disease, and hiatal hernia associated with reflux esophagitis) and in patients taking other anticholinergic medications [see Drug Interactions (7.1)]. 5.7 Increased Risk of Anticholinergic Adverse Reactions in Geriatric Patients Geriatric patients 65 years of age and older are at increased risk of anticholinergic adverse reactions that may lead to complications of urinary retention, bowel obstruction, heat prostration, arrhythmias, delirium, and falls or fractures. Glycopyrrolate are not recommended in geriatric patients and may be contraindicated in some geriatric patients with underlying medical conditions [see Contraindications (4), Warnings and Precautions (5.2, 5.5), Adverse Reactions (6) and Use in Specific Populations (8.5)].

The following serious or otherwise important adverse reactions are discussed elsewhere in the labeling:

• Precipitation of Acute Glaucoma [see Warnings and Precautions (5.1)]
• Partial or Complete Mechanical Intestinal Obstruction [see Warnings and Precautions (5.2)]
• Gastrointestinal Adverse Reactions due to Decreased Gastrointestinal Motility [see Warnings and Precautions (5.3)]
• Cognitive and Visual Adverse Reactions [see Warnings and Precautions (5.4)]
• Heat Prostration at High Environmental Temperatures [see Warnings and Precautions (5.5)]
• Other Conditions Exacerbated by Anticholinergic Adverse Reactions [see Warnings and Precautions (5.6)]
• Increased Risk of Anticholinergic Adverse Reactions in Geriatric Patients [see Warnings and Precautions (5.7)] The following adverse reactions associated with the use of glycopyrrolate, or other anticholinergic drugs, were identified in clinical studies or postmarketing reports. Because some of these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Cardiac Disorders: chest, pain, hypertension, tachycardia Endocrine Disorders: decreased sweating Eye Disorders: blurred vision, cycloplegia, dilatation of the pupil, increased ocular tension Gastrointestinal Disorders: bloated feeling, constipation, dry mouth, dysgeusia, nausea, vomiting Immune System Disorders: anaphylaxis [see Contraindications (4)] Nervous System Disorders: agitation, dizziness, drowsiness, headache, insomnia, mental confusion, nervousness, weakness Respiratory Disorders: respiratory depression, throat irritation Renal and Urinary Disorders: urinary hesitancy, urinary retention Reproductive System and Breast Disorders: impotence, suppression of lactation Vascular Disorders: flushing Adverse reactions include blurred vision, drowsiness, decreased sweating, flushing, vomiting, constipation, dry mouth, tachycardia, and urinary retention.

• 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)

7.1Other 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. Co-administration of antipsychotics with glycopyrrolate may lead to worsening of tardive dyskinesia. Glycopyrrolate are 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 to increased or decreased drug exposure. Glycopyrrolate are 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 Oral 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 are not recommended in patients taking solid oral dosage forms of potassium chloride.

• Renal Impairment: Monitor patients with renal impairment; if anticholinergic adverse reactions occur, discontinue use. (8.6)

8.1Pregnancy 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)]. 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. 8.5 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 are 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)]. 8.6 Renal Impairment Glycopyrrolate is substantially excreted by the kidney [see Clinical Pharmacology (12.3)]. Monitor patients with renal impairment for anticholinergic adverse reactions [see Adverse Reactions (6)]. If anticholinergic adverse reactions occur, discontinue glycopyrrolate.
