This drug may cause drowsiness, dizziness, and/or blurred vision, if affected, do not drive or operate machinery.

Obtain FEV₁, FVC, and/or other pulmonary function tests, serum K, blood glucose. Monitor heart rate, blood pressure and signs of CNS stimulation.

Indacaterol: May potentiate hypokalaemic effect with xanthine derivatives, steroids, diuretics. May potentiate CV effects with MAOIs, TCA, QTc-prolonging agents. May cause sever bronchospasm with β-blockers.
Glycopyrronium: Increased adverse effects with other anticholinergic drugs.

Description: Indacaterol is a long acting beta₂- agonist that acts locally in the lungs and relaxes bronchial smooth muscle.
Glycopyrronium is a long acting muscarinic receptor antagonist. It causes bronchodilatation by inhibiting the acetylcholine at muscarinic receptor subtypes 1-3 in bronchial smooth muscles.
Onset: Within 5 minutes.
Pharmacokinetics:
Absorption: Indacaterol: Absolute bioavailability: 43-45%. Time to peak plasma concentration: Approx 15 minutes.
Glycopyrronium: Poorly absorbed from the gastrointestinal tract. Bioavailability: Approx 10-25%. Time to peak plasma concentration: Approx 5 minutes.
Distribution: Indacaterol: Plasma protein binding: Approx 95%.
Glycopyrronium: Crosses blood-brain barrier (poorly). Volume of distribution: 83 L. Plasma protein binding: 38-41%.
Metabolism: Indacaterol: Metabolised by CYP3A4 isoenzyme and via glucuronidation by uridine diphosphate-glucuronosyltransferase (UGT) 1A1.
Excretion: Indacaterol: Via faeces (54% as unchanged drug, 23% as metabolites); urine. Elimination half-life: 40-56 hours.
Glycopyrronium: Via faeces; urine (23% as parent drug). Terminal elimination half-life: 33-57 hours.
