Glycopyrronium Bromide Mercurypharm Ltd (Glycopyrronium Bromide)

Glycopyrronium bromide is used in clinical practice to control excessive secretions and support cardiac function in specific settings.

• Reduction of salivary secretions during surgery to improve airway management.
• Decrease of respiratory tract secretions in peri‑operative patients.
• Adjunct therapy for bronchospasm associated with anesthesia.
• Management of intra‑operative bradycardia when other agents are unsuitable.
• Facilitation of endotracheal intubation by minimizing oral and pharyngeal secretions.

Side effects of glycopyrronium bromide vary in frequency and severity.

Common

• Dry mouth (xerostomia).
• Throat irritation.
• Mild tachycardia.
• Transient facial flushing.
• Nausea.
• Dizziness.

Serious

• Severe tachyarrhythmias.
• Acute urinary retention.
• Angle‑closure glaucoma.
• Anaphylactic reaction.
• Prolonged bronchospasm.
• Persistent hypotension.

When prescribing glycopyrronium bromide, clinicians should consider several safety aspects.

• Assess for a history of glaucoma, especially narrow‑angle type.
• Use caution in patients with urinary retention or prostatic hypertrophy.
• Monitor heart rate and rhythm in individuals with cardiac disease.
• Evaluate renal and hepatic function before dosing, as impairment may affect clearance.
• Avoid in patients with known hypersensitivity to anticholinergic agents.
• Consider dose adjustment in elderly patients due to increased sensitivity to anticholinergic effects.

Glycopyrronium bromide may interact with other medications, influencing its safety and efficacy.

Avoid

• Concurrent use with other anticholinergic drugs (e.g., atropine, scopolamine) that may exacerbate dry mouth and tachycardia.
• Combination with beta‑blockers in patients prone to bradycardia.
• Co‑administration with drugs that prolong QT interval.

Use with caution

• Opioid analgesics, as reduced secretions may mask signs of respiratory depression.
• Diuretics, due to potential additive effects on electrolyte balance.
• Anesthetic agents that have cholinergic activity.
• Medications affecting renal excretion, such as aminoglycosides.
