Glycopyrrolate tablets are contraindicated in: Patients at risk for anticholinergic toxicity due to an underlying medical condition, including: Glaucoma [see Warnings and Precautions (5.1)] Obstructive uropathies, including prostatic hypertrophy Mechanical obstructive diseases of the gastrointestinal tract (e.g., pyloroduodenal stenosis, strictures) [see Warnings and Precautions (5.2)] Gastrointestinal motility disorders (e.g., achalasia, paralytic ileus, intestinal atony) [see Warnings and Precautions (5.3)] Bleeding gastrointestinal ulcer Active inflammatory or infectious colitis which can lead to toxic megacolon History of or current toxic megacolon Myasthenia gravis Patients with a hypersensitivity to glycopyrrolate or any of the inactive ingredients in Glycopyrrolate tablet 1 mg and Glycopyrrolate tablet 2 mg [see Adverse Reactions (6) and Description (11) ] Patients at risk for anticholinergic toxicity due to various underlying medical conditions. (4, 5.1, 5.2, 5.3) Hypersensitivity to glycopyrrolate or the inactive ingredients. (4)

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)

Glycopyrrolate may cause increased intraocular pressure in patients with glaucoma and reduce the effects of antiglaucoma agents. Instruct patients to discontinue Glycopyrrolate tablets 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) ].

Glycopyrrolate tablets 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 tablets and evaluate for potential intestinal obstruction [see Contraindications (4) ].

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 tablets and other anticholinergics or other medications that decrease GI peristalsis is not recommended [see Drug Interactions (7.2) ].

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 tablets does not affect them adversely. Discontinue Glycopyrrolate tablets if signs or symptoms of cognitive or visual impairment develop.

In the presence of a high environmental temperature, heat prostration resulting in fever and heatstroke can occur with the use of Glycopyrrolate tablets 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 tablets. Glycopyrrolate tablets are not recommended in geriatric patients [see Warnings and Precautions (5.7) ].

Glycopyrrolate tablets 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) ].

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 tablet 1 mg and Glycopyrrolate tablet 2 mg 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)

There is potential for an additive interaction between glycopyrrolate and concomitantly used anticholinergic drugs (e.g., tricyclic antidepressants, anti-epileptics, class I antiarrhythmics, antispasmodics, amantadine) resulting in increased anticholinergic adverse reactions. Co-administration of antipsychotics with glycopyrrolate may lead to worsening of tardive dyskinesia. Glycopyrrolate tablets are not recommended in patients taking other anticholinergic drugs [see Warnings and Precautions (5.3, 5.4, 5.6) ].

Decreased gastrointestinal motility by glycopyrrolate may impact absorption of other drugs leading to increased or decreased drug exposure. Glycopyrrolate tablets are not recommended in patients taking other drugs that are affected by altered gastrointestinal motility [see Warnings and Precautions (5.3)].

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 tablets 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)

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 animalstudies, 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 body weight 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 body weight 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) ].

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 tablets and any potential adverse effects on the breastfed infant from Glycopyrrolate tablets.

Safety and effectiveness in pediatric patients have not been established.

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 tablets 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) ].

Glycopyrrolate is substantially excreted by the kidneys [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 tablets.

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.

Glycopyrrolate tablets USP for oral use contain synthetic anticholinergic glycopyrrolate. Glycopyrrolate is a quaternary ammonium compound with the following chemical name: 3-[(cyclopentyl hydroxyphenylacetyl)oxy]-1,1-dimethylpyrrolidinium bromide. The molecular formula for glycopyrrolate is C19H28BrNO3, the molecular weight is 398.3 g/mol, and the structural formula is: Each Glycopyrrolate tablet USP for oral use contains glycopyrrolate, USP 1 mg, or 2 mg as the active ingredient. The inactive ingredients are dibasic calcium phosphate, lactose monohydrate, magnesium stearate, povidone, and sodium starch glycolate. chemstructure

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.

No formal pharmacodynamic studies have been conducted with Glycopyrrolate tablets.

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)].

Reproduction studies in rats resulted in diminished rates of conception in a dose-related manner. Studies in dogs suggest that diminished rates of conception may be due to diminished seminal secretion, which is evident at high doses of glycopyrrolate.
