Novistig (Glycopyrronium Bromide, Neostigmine Methylsulfate)

Glycopyrronium bromide and Neostigmine methylsulfate, the active ingredients in Novistig, are an anticholinergic muscarinic antagonist and an acetylcholinesterase inhibitor presented for intravenous use. They are employed to relieve bronchospasm in chronic obstructive pulmonary disease or asthma and to reverse non‑depolarizing neuromuscular blockade after surgery.

GNH USA supplies Novistig as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Novistig acts on the respiratory and neuromuscular systems to manage acute and chronic airway constriction and to restore muscle function after surgery.

- Bronchospasm associated with COPD or asthma: provides bronchodilation and reduces airway secretions. - Reversal of neuromuscular blockade after surgery: restores muscle strength by increasing acetylcholine at the neuromuscular junction. - Acute bronchospasm: delivers rapid relief of airway constriction during emergency episodes.

Novistig may cause a range of adverse reactions, from mild to severe, depending on patient sensitivity and clinical context.

Common Side Effects: - Dry mouth: reduced salivary secretion. - Urinary retention: difficulty initiating urination. - Tachycardia: increased heart rate. - Headache: mild to moderate intensity.

Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction requiring immediate medical attention. - Cardiac arrhythmia: irregular heart rhythm that may be life‑threatening. - Prolonged neuromuscular blockade: persistent muscle weakness after surgery.

Before administering Novistig, clinicians should consider several safety measures.

- Cardiac monitoring: observe for tachycardia or arrhythmias. - Urinary assessment: evaluate for pre‑existing retention or obstruction. - Glaucoma caution: avoid in patients with narrow‑angle glaucoma. - Renal function: adjust use in severe renal impairment. - Store at room temperature: keep in original container, protect from moisture and light.

Novistig can interact with other medicines, altering efficacy or safety.

Major Interactions (Avoid): - Non‑depolarizing neuromuscular blockers: may reduce reversal effectiveness. - Anticholinergic agents: can increase risk of dry mouth and urinary retention.

Moderate Interactions (Monitor Closely): - Beta‑agonists: additive bronchodilatory effect may cause tachycardia. - Renally excreted drugs (e.g., aminoglycosides): may require dose adjustment. - Certain antihypertensives: potential for additive cardiovascular effects.
