Side Effects & Adverse Reactions

This drug should be used with great caution, if at all, in patients with glaucoma.

Exposure to excessive amounts of benzyl alcohol has been associated with toxicity (hypotension, metabolic acidosis), particularly in neonates, and an increased incidence of kernicterus, particularly in small preterm infants. There have been rare reports of deaths, primarily in preterm infants, associated with exposure to excessive amounts of benzyl alcohol. The amount of benzyl alcohol from medications is usually considered negligible compared to that received in flush solutions containing benzyl alcohol. Administration of high dosages of medications containing this preservative must take into account the total amount of benzyl alcohol administered. The amount of benzyl alcohol at which toxicity may occur is not known. If the patient requires more than the recommended dosages or other medications containing this preservative, the practitioner must consider the daily metabolic load of benzyl alcohol from these combined sources. (seePRECAUTIONS, Pediatric Use).

ROBINUL Injection may produce drowsiness or blurred vision. The patient should be cautioned regarding activities requiring mental alertness such as operating a motor vehicle or other machinery or performing hazardous work while taking this drug.

In addition, in the presence of fever, high environmental temperature and/or during physical exercise, heat prostration can occur with use of anticholinergic agents including glycopyrrolate (due to decreased sweating), particularly in children and the elderly.

Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. In this instance treatment with ROBINUL Injection would be inappropriate and possibly harmful.

Uses

In Anesthesia

ROBINUL Injection is indicated for use as a preoperative antimuscarinic to reduce salivary, tracheobronchial, and pharyngeal secretions; to reduce the volume and free acidity of gastric secretions; and to block cardiac vagal inhibitory reflexes during induction of anesthesia and intubation. When indicated, ROBINUL Injection may be used intraoperatively to counteract surgically or drug-induced or vagal reflexes associated arrhythmias. Glycopyrrolate protects against the peripheral muscarinic effects (e.g., bradycardia and excessive secretions) of cholinergic agents such as neostigmine and pyridostigmine given to reverse the neuromuscular blockade due to non-depolarizing muscle relaxants.

In Peptic Ulcer

For use in adults as adjunctive therapy for the treatment of peptic ulcer when rapid anticholinergic effect is desired or when oral medication is not tolerated.

History

Other Information

ROBINUL (glycopyrrolate) Injection is a synthetic anticholinergic agent. Each 1 mL contains:

Glycopyrrolate, USP 0.2 mg

Water for Injection, USP q.s.

Benzyl Alcohol, NF 0.9% (preservative)

pH adjusted, when necessary, with hydrochloric acid and/or sodium hydroxide.

For Intramuscular (IM) or Intravenous (IV) administration.

Glycopyrrolate is a quaternary ammonium salt with the following chemical name: 3[(cyclopentylhydroxyphenylacetyl)oxy]-1,1-dimethyl pyrrolidinium bromide. The molecular formula is C19H28BrNO3 and the molecular weight is 398.33.

Its structural formula is as follows:

C19H28BrNO3 MW 398.33

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. ROBINUL (glycopyrrolate) Injection is a clear, colorless, sterile liquid; pH 2.0– 3.0. The partition coefficient of glycopyrrolate in a n-octanol/water system is 0.304 (log10 P= -1.52) at ambient room temperature (24°C).
