Novistig (Glycopyrronium Bromide, Neostigmine Methylsulfate)

Glycopyrronium bromide, the active ingredient in Novistig, is a muscarinic antagonist presented as a solution for injection for intravenous use. It reduces secretions and smooth‑muscle activity and, together with neostigmine methylsulfate, is employed in peri‑operative settings to manage airway secretions and reverse neuromuscular blockade. GNH USA supplies Novistig as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals and clinics worldwide.

Novistig combines a muscarinic antagonist and an acetylcholinesterase inhibitor, acting on the autonomic and neuromuscular systems. - Preoperative secretions control: reduces oral and respiratory secretions to improve airway management. - Reversal of neuromuscular blockade: enhances acetylcholine at the neuromuscular junction to restore muscle strength after surgery. - Postoperative ileus management: stimulates gastrointestinal motility to accelerate return of bowel function.

Novistig may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Dry mouth: reduced salivary flow leading to throat discomfort. - Blurred vision: transient visual disturbances due to ocular muscle effects. - Nausea: mild gastrointestinal upset after injection. - Muscle fasciculations: brief twitching of skeletal muscles.

Serious or Rare Side Effects: - Bradycardia or severe arrhythmia: marked slowing of heart rate requiring monitoring. - Bronchospasm: acute constriction of airway smooth muscle, especially in asthmatic patients. - Anaphylactic reaction: rare but potentially life‑threatening hypersensitivity. - Cholinergic crisis: excessive acetylcholine causing muscle weakness and respiratory compromise.

Use Novistig only under qualified medical supervision and consider patient‑specific factors. - Renal impairment: monitor renal function as the drug is primarily excreted unchanged. - Cardiac disease: observe heart rate and rhythm due to possible bradycardia or tachyarrhythmia. - Asthma or COPD: administer cautiously because of potential bronchospasm. - Pregnancy: prescribe only when the anticipated benefit justifies potential fetal risk. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Novistig can interact with several drug classes; careful assessment is required.

Major Interactions (Avoid): - Beta‑blockers: may exacerbate bradycardia. - Other anticholinergic agents: additive dry‑mouth, urinary retention, and tachycardia. - Concurrent cholinesterase inhibitors (e.g., pyridostigmine): risk of cholinergic excess.

Moderate Interactions (Monitor Closely): - Opioids: may increase postoperative ileus risk. - Diuretics: potential additive hypotensive effect. - Anesthetic agents (e.g., succinylcholine): monitor neuromuscular transmission closely.
