Glycopyrrolate

1 INDICATIONS AND USAGE Glycopyrrolate Injection is an anticholinergic indicated: in anesthesia (adult and pediatric patients) for reduction of salivary, tracheobronchial, and pharyngeal secretions, reduction of volume and acidity of gastric secretions, and blockade of cardiac inhibitory reflexes during induction of anesthesia and intubation. intraoperatively to counteract surgically or drug-induced or vagal reflex-associated arrhythmias. for protection against peripheral muscarinic effects of cholinergic agents. ( 1 ) in peptic ulcer (adults) To reduce symptoms of a peptic ulcer as an adjunct to treatment of peptic ulcer when rapid anticholinergic effect is desired or oral medication is not tolerated. Limitations of Use Glycopyrrolate Injection is not indicated as monotherapy for the treatment of peptic ulcer because effectiveness in peptic ulcer healing has not been established. ( 1 ) 1.1 Preanesthetic Glycopyrrolate Injection is indicated in adults and pediatric patients for reduction of salivary, tracheobronchial, and pharyngeal secretions, reduction of volume and acidity of gastric secretions, and blockade of cardiac inhibitory reflexes during induction of anesthesia and intubation. 1.2 Intraoperative Glycopyrrolate Injection is indicated in adults and pediatric patients to counteract surgically or drug-induced or vagal reflex-associated arrhythmias. 1.3 Reversal of Neuromuscular Blockade Glycopyrrolate Injection is indicated in adults and pediatric patients for protection against peripheral muscarinic effects of cholinergic agents such as neostigmine and pyridostigmine given to reverse the neuromuscular blockade due to non-depolarizing agents. 1.4 Peptic Ulcer Glycopyrrolate Injection is indicated in adults to reduce symptoms of a peptic ulcer as an adjunct to treatment of peptic ulcer when rapid anticholinergic effect is desired or when oral medication is not tolerated. Limitations of Use Glycopyrrolate Injection is not indicated as monotherapy for the treatment of peptic ulcer because effectiveness in peptic ulcer healing has not been established.

5 WARNINGS AND PRECAUTIONS Precipitation of Acute Glaucoma : May cause mydriasis and increase intraocular pressure in patients with glaucoma. Advise patients with glaucoma to promptly seek medical care if they experience symptoms of acute angle closure glaucoma. ( 5.1 ) Drowsiness or Blurred Vision : May cause drowsiness or blurred vision. Advise patients not to drive or perform hazardous work until resolved. ( 5.2 ) Heat Prostration : Advise patients to avoid exertion and high environmental temperatures after receiving glycopyrrolate injection. ( 5.3 ) Intestinal Obstruction : Diarrhea may be an early symptom of incomplete intestinal obstruction. Avoid use in patients with diarrhea and ileostomy or colostomy. ( 5.4 ) Tachycardia : Increase in heart rate may occur. Use with caution in patients with coronary artery disease, congestive heart failure, cardiac arrhythmias, hypertension, or hyperthyroidism. ( 5.5 ) 5.1 Precipitation of Acute Glaucoma Glycopyrrolate injection may cause mydriasis and increase intraocular pressure in patients with glaucoma. Advise patients with glaucoma to promptly seek medical care in the event that they experience symptoms of acute angle closure glaucoma (pain and reddening of the eyes, accompanied by dilated pupils). 5.2 Drowsiness or Blurred Vision Glycopyrrolate injection may cause drowsiness or blurred vision. Warn patients not to participate in activities requiring mental alertness, such as operating a motor vehicle or other machinery or performing hazardous work, until these issues resolve. 5.3 Heat Prostration In the presence of fever, high environmental temperature, and/or during physical exercise, heat prostration can occur with use of anticholinergic agents including glycopyrrolate injection (due to decreased sweating), particularly in children and the elderly. Advise patients to avoid exertion and high environmental temperature after receiving glycopyrrolate injection. 5.4 Intestinal Obstruction Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. In this instance treatment with glycopyrrolate injection is inappropriate and possibly harmful. Glycopyrrolate is contraindicated in patients with these conditions. 5.5 Tachycardia Investigate any tachycardia before giving glycopyrrolate injection because an increase in the heart rate may occur. Use with caution in patients with coronary artery disease, congestive heart failure, cardiac arrhythmias, hypertension, or hyperthyroidism. 5.6 Risk of Use in Patients with Renal Impairment Renal elimination of glycopyrrolate may be significantly reduced in patients with renal failure. Dosage adjustments may be necessary in this population [ see Clinical Pharmacology ( 12.3 ) ]. 5.7 Autonomic Neuropathy, Hepatic Disease, Ulcerative Colitis, Prostatic Hypertrophy, or Hiatal Hernia Use glycopyrrolate injection with caution in the elderly and in all patients with autonomic neuropathy, hepatic disease, ulcerative colitis, prostatic hypertrophy, or hiatal hernia, because anticholinergic drugs may aggravate these conditions. Consider dose reduction and closely monitor the elderly and patients with autonomic neuropathy, hepatic disease, ulcerative colitis, prostatic hypertrophy, or hiatal hernia. 5.8 Delayed Gastric Emptying/Gastric Stasis The use of anticholinergic drugs, including glycopyrrolate injection, in the treatment of peptic ulcer may produce a delay in gastric emptying due to antral stasis. Monitor patients for symptoms such as vomiting, dyspepsia, early satiety, abdominal distention, and increased abdominal pain. Discontinue glycopyrrolate injection treatment if these symptoms develop or worsen on treatment. 5.9 Light Sensitivity Patients may experience sensitivity of the eyes to light. Advise patients to protect their eyes from light after receiving glycopyrrolate injection.

6 ADVERSE REACTIONS The following adverse reactions were identified in clinical studies or postmarketing reports. Because some of these reactions were 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. Adverse reactions to anticholinergics include xerostomia (dry mouth); urinary hesitancy and retention; blurred vision and photophobia due to mydriasis (dilation of the pupil); cycloplegia; increased ocular tension; tachycardia; palpitation; decreased sweating; loss of taste; headache; nervousness; drowsiness; weakness; dizziness; insomnia; nausea; vomiting; impotence; suppression of lactation; constipation; bloated feeling; severe allergic reactions including anaphylactic/anaphylactoid reactions; hypersensitivity; urticaria, pruritus, dry skin, and other dermal manifestations; some degree of mental confusion and/or excitement, especially in elderly persons. The following adverse events have been reported from post-marketing experience with glycopyrrolate: malignant hyperthermia; cardiac arrhythmias (including bradycardia, ventricular tachycardia, ventricular fibrillation); cardiac arrest; hypertension; hypotension; seizures; and respiratory arrest. Post-marketing reports have included cases of heart block and QTc interval prolongation associated with the combined use of glycopyrrolate and an anticholinesterase. Injection site reactions including pruritus, edema, erythema, and pain have also been reported. Most common adverse reactions are related to anticholinergic pharmacology and may include xerostomia (dry mouth); urinary hesitancy and retention; blurred vision and photophobia due to mydriasis (dilation of the pupil); cycloplegia; increased ocular tension; tachycardia; bradycardia; palpitation; and decreased sweating.

8 USE IN SPECIFIC POPULATIONS Pediatric Use : Infants, patients with Down’s Syndrome, and pediatric patients with spastic paralysis or brain damage may experience an increased response to anticholinergics, thus increasing the potential for side effects. Large doses may cause hyperexcitability. ( 8.4 ) 8.1 Pregnancy Risk Summary Limited available data over decades of use with glycopyrrolate in pregnant women have not identified a drug-associated risk of birth defects and miscarriage, however, most of the reported exposures occurred after the first trimester. Most of the available data are based on studies with exposures that occurred at the time of Cesarean section delivery, and these studies have not identified an adverse effect on maternal outcomes or infant Apgar scores (see Data). In animal reproduction studies in pregnant rats and rabbits administered glycopyrrolate orally (rats) and intramuscularly (rabbits) during the period of organogenesis, no teratogenic effects were seen at 320-times and 5-times the maximum recommended human dose (MRHD) of 2 mg (on a mg/m 2 basis), respectively (see Data) . The background risk for 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 the clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Human Data Published, randomized, controlled trials over several decades, which compared the use of glycopyrrolate to another antimuscarinic agent in pregnant women during Cesarean section, have not identified adverse maternal or infant outcomes. In normal doses (0.004 mg/kg), glycopyrrolate does not appear to affect fetal heart rate or fetal heart rate variability to a significant degree. Concentrations of glycopyrrolate in umbilical venous and arterial blood and in the amniotic fluid are low after intramuscular administration to parturients. Therefore, glycopyrrolate does not appear to penetrate through the placental barrier in significant amounts. There are no studies on the safety of glycopyrrolate exposure during the period of organogenesis, and therefore, it is not possible to draw any conclusions on the risk of birth defects following exposure to glycopyrrolate during pregnancy. In addition, there are no data on the risk of miscarriage following fetal exposure to glycopyrrolate. Animal Data Reproduction studies with glycopyrrolate were performed in rats at a dietary dose of approximately 65 mg/kg/day (exposure was approximately 320 times the maximum recommended daily human dose of 2 mg on a mg/m 2 basis) and rabbits at intramuscular doses of up to 0.5 mg/kg/day (exposure was approximately 5 times the maximum recommended daily human dose on a mg/m 2 basis). These studies produced no teratogenic effects to the fetus. A preclinical study on reproductive performance of rats given glycopyrrolate resulted in a decreased rate of conception and survival at weaning. 8.2 Lactation Risk Summary There are no data on the presence of glycopyrrolate in either human milk or animal milk, the effects on the breastfed infant, or the effects on milk production. As with other anticholinergics, glycopyrrolate may cause suppression of lactation [see Adverse Reactions ( 6 )] . The developmental and health benefits of breast feeding should be considered along with the mother’s clinical need for glycopyrrolate injection and any potential adverse effects on the breastfed child from glycopyrrolate injection or from the underlying maternal condition. 8.4 Pediatric Use Glycopyrrolate injection is indicated in pediatric patients: for reduction of salivary, tracheobronchial, and pharyngeal secretions, reduction of volume and acidity of gastric secretions, and blockade of cardiac inhibitory reflexes during induction of anesthesia and intubation intraoperatively to counteract surgically or drug-induced or vagal reflex-associated arrhythmias for protection against peripheral muscarinic effects of cholinergic agents such as neostigmine and pyridostigmine given to reverse the neuromuscular blockade due to non-depolarizing agents Heat prostration can occur in pediatric patients in the presence of fever, high environmental temperature, and/or during physical exercise with use of anticholinergic agents including glycopyrrolate injection [see Warnings and Precautions ( 5.3 )] . Young pediatric patients (and especially those less than 1 month of age), patients with Down syndrome, and pediatric patients with spastic paralysis or brain damage may experience an increased response to anticholinergics, thus increasing the potential for side effects. A paradoxical reaction characterized by hyperexcitability may occur in pediatric patients receiving large doses of anticholinergics including glycopyrrolate injection. Dysrhythmias associated with the use of glycopyrrolate intravenously as a premedicant or during anesthesia have been observed in pediatric patients. The safety and effectiveness of glycopyrrolate injection for treatment of peptic ulcer have not been established in pediatric patients. 8.5 Geriatric Use Clinical studies of glycopyrrolate injection did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other therapy. 8.6 Renal Impairment Renal elimination of glycopyrrolate may be significantly reduced in patients with renal failure. Dosage adjustments may be necessary [see Clinical Pharmacology ( 12.3 )] .
