Glycopyrrolate

RECENT MAJOR CHANGES

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.

2 DOSAGE AND ADMINISTRATION Glycopyrrolate injection may be administered intramuscularly (IM), or intravenously (IV) without dilution, in the following indications. ( 2.1 ): Adults ( 2.2 , 2.3 , 2.4 , 2.5 ) Preanesthetic Medication: 0.004 mg/kg IM, given 30 to 60 minutes prior to the anticipated time of induction of anesthesia Intraoperative Medication: single doses of 0.1 mg IV and repeated, as needed, at intervals of 2 to 3 minutes Reversal of Neuromuscular Blockade: 0.2 mg for each 1 mg of neostigmine or 5 mg of pyridostigmine Peptic Ulcer: 0.1 mg IV or IM at 4-hour intervals, 3 or 4 times daily Pediatric patients ( 2.2 , 2.3 , 2.4 ) Preanesthetic Medication: 0.004 mg/kg IM, given 30 to 60 minutes prior to the anticipated time of induction of anesthesia. Patients under 2 years of age may require up to 0.009 mg/kg Intraoperative Medication: 0.004 mg/kg IV, not to exceed 0.1 mg in a single dose and repeated, as needed, at intervals of 2 to 3 minutes Reversal of Neuromuscular Blockade: 0.2 mg IV for each 1 mg of neostigmine or 5 mg of pyridostigmine Peptic Ulcer: Glycopyrrolate injection is not indicated for the treatment of peptic ulcer in pediatric patients Do not use this prefilled syringe to administer a dose of less than 0.1 mg (0.5 mL). ( 2.2 , 2.3 , 2.4 ) 2.1 Important Dosage and Administration Instructions Dosing of this glycopyrrolate injection product is not possible in patients who require doses less than 0.1 mg because the recommended dose cannot be achieved with the supplied pre-filled syringe. For patients who require doses less than 0.1 mg, use another glycopyrrolate injection product that allows dosing of less than 0.1 mg. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Glycopyrrolate injection may be administered intramuscularly or intravenously, without dilution. Do not introduce any other fluid into the syringe at any time. Do not dilute for IV push. Do not re-sterilize the syringe. Do not use this product on a sterile field. This product is for single dose only. 2.2 Recommended Dosage of Preanesthetic Medication in Adults and Pediatric Patients The recommended dose of glycopyrrolate injection is 0.004 mg/kg by intramuscular injection, given 30 to 60 minutes prior to the anticipated time of induction of anesthesia or at the time the preanesthetic narcotic and/or sedative are administered. Patients less than 2 years of age may require up to 0.009 mg/kg. Do not use this prefilled syringe to administer a dose of less than 0.1 mg (0.5 mL). 2.3 Recommended Dosage as Intraoperative Medication to Counteract Drug-induced or Vagal Reflexes and Their Associated Arrhythmias (e.g., bradycardia) in Adults and Pediatric Patients The recommended adult dose of glycopyrrolate injection is 0.1 mg intravenously. Repeat this dose, as needed, at intervals of 2 to 3 minutes. The recommended pediatric dosage is 0.004 mg/kg intravenously, not to exceed 0.1 mg in a single dose, repeated every 2 to 3 minutes. Attempt to determine the etiology of the arrhythmia, and perform the surgical or anesthetic manipulations necessary to correct parasympathetic imbalance. Because of the long duration of action of glycopyrrolate injection if used as preanesthetic medication, additional glycopyrrolate injection for anticholinergic effect intraoperatively is rarely needed. Do not use this prefilled syringe to administer a dose of less than 0.1 mg (0.5 mL). 2.4 Recommended Dosage for Reversal of Neuromuscular Blockade in Adults and Pediatric Patients The recommended dose of glycopyrrolate injection is 0.2 mg intravenous for each 1 mg of neostigmine or 5 mg of pyridostigmine. In order to minimize the appearance of cardiac side effects, the drugs may be administered simultaneously by intravenous injection. Do not use this prefilled syringe to administer a dose of less than 0.1 mg (0.5 mL). 2.5 Recommended Dosage for Peptic Ulcer in Adults The …

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. The following is discussed in more detail in other sections of the labeling. • Benzyl Alcohol Toxicity : Due to its benzyl alcohol content, glycopyrrolate injection should not be used in neonates, i.e., patients less than 1 month of age [see Warnings and Precautions ( 5.10 ) and Use in Specific Populations ( 8.4 )] . 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.

7 DRUG INTERACTIONS The concurrent use of glycopyrrolate injection with other anticholinergics or medications with anticholinergic activity, such as phenothiazines, antiparkinson drugs, or tricyclic antidepressants, may intensify the antimuscarinic effects and result in an increase in anticholinergic side effects. Concomitant administration of glycopyrrolate injection and potassium chloride in a wax matrix may increase the severity of potassium chloride-induced gastrointestinal lesions as a result of a slower gastrointestinal transit time. Other anticholinergics or drugs with anticholinergic activity : May intensify the antimuscarinic effects and result in an increase in anticholinergic side effects. ( 7 ) Potassium Chloride in a Wax Matrix : May increase severity of potassium chloride-induced gastrointestinal lesions. ( 7 )

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 ) See 17 for PATIENT COUNSELING INFORMATION. 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/m2 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/m2 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/m2 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 …

12.1 Mechanism of Action Glycopyrrolate, like other anticholinergic (antimuscarinic) agents, inhibits the action of acetylcholine on structures innervated by postganglionic cholinergic nerves and on smooth muscles that respond to acetylcholine but lack cholinergic innervation. These peripheral cholinergic receptors are present in the autonomic effector cells of smooth muscle, cardiac muscle, the sinoatrial node, the atrioventricular node, exocrine glands and, to a limited degree, in the autonomic ganglia. Thus, it diminishes the volume and free acidity of gastric secretions and controls excessive pharyngeal, tracheal, and bronchial secretions.

DESCRIPTION Glycopyrrolate Injection, USP is a clear, colorless, sterile solution of Glycopyrrolate, USP with Benzyl Alcohol, NF in Water for Injection, USP. The formulation is used for intramuscular or intravenous administration. Each mL contains: Glycopyrrolate, USP................................0.2 mg Benzyl Alcohol, NF (preservative).................0.9% Water for Injection, USP.................................... q.s. When necessary, pH (2.0 to 3.0) adjusted with hydrochloric acid and/or sodium hydroxide. Glycopyrrolate is a quaternary ammonium salt with the following chemical name: 3[(cyclopentylhydroxyphenylacetyl)oxy]-1, 1-dimethyl pyrrolidinium bromide. Glycopyrrolate is a synthetic anticholinergic agent that has the following molecular structure and molecular weight. Glycopyrrolate occurs as a white, odorless crystalline powder. It is soluble in water and alcohol, and practically insoluble in chloroform and ether. Unlike atropine, glycopyrrolate is completely ionized at physiological pH values. The partition coefficient of glycopyrrolate in a n-octanol/water system is 0.304 (log 10 P= -1.52) at ambient room temperature (24°C). 4d517ecd-figure-01

OVERDOSAGE To combat peripheral anticholinergic effects, a quaternary ammonium anticholinesterase such as neostigmine methylsulfate (which does not cross the blood-brain barrier) may be given intravenously in increments of 0.25 mg in adults. This dosage may be repeated every five to ten minutes until anticholinergic overactivity is reversed or up to a maximum of 2.5 mg. Proportionately smaller doses should be used in pediatric patients. Indication for repetitive doses of neostigmine should be based on close monitoring of the decrease in heart rate and the return of bowel sounds. If CNS symptoms (e.g., excitement, restlessness, convulsions, psychotic behavior) occur, physostigmine (which does cross the blood-brain barrier) may be used. Physostigmine 0.5 to 2 mg should be slowly administered intravenously and repeated as necessary up to a total of 5 mg in adults. Proportionately smaller doses should be used in pediatric patients. To combat hypotension, administer intravenous fluids and/or pressor agents along with supportive care. Fever should be treated symptomatically. Following overdosage, a curare-like action may occur, i.e., neuromuscular blockade leading to muscular weakness and possible paralysis. In the event of a curare-like effect on respiratory muscles, artificial respiration should be instituted and maintained until effective respiratory action returns.
