Indacaterol


Generic Medicine Info
Indications and Dosage
Inhalation/Respiratory
Chronic obstructive pulmonary disease
Adult: Maintenance: As inhalation cap: 1 cap (150 mcg) once daily via inhaler device, at the same time each day. Severe: 300 mcg once daily. Max: 300 mcg daily.
Special Patient Group
Pharmacogenomics:

Indacaterol is metabolised by uridine diphosphate glucuronosyltransferase 1 family, polypeptide A1 (UGT1A1) enzyme via glucuronidation into phenolic O-glucuronide metabolite.

According to FDA-approved drug label, patients with UGT1A1 (TA)7/(TA)7 (*28/*28) low expression genotype have 1.2-fold higher steady-state AUC and Cmax than in patients with (TA)6/(TA)6 (*1/*1) genotype. This suggests that UGT1A1 genotype has no significant effect in the exposure of indacaterol.
Contraindications
As monotherapy in the treatment of asthma. Concomitant use with other long-acting ß2-adrenergic agonists.
Special Precautions
Patient with CV disorders (e.g. coronary artery disease, acute MI, cardiac arrhythmias, hypertension, known or suspected QT interval prolongation); convulsive disorders, hyperthyroidism, diabetes mellitus, hypokalaemia. Pregnancy and lactation. Not indicated for the relief of acute bronchospasm.
Adverse Reactions
Significant: Hypersensitivity reactions (e.g. swelling of tongue, lips and face, rash, urticaria, difficulty in breathing or swallowing), hypokalaemia, hyperglycaemia, new-onset or exacerbation of diabetes mellitus, increased pulse rate or blood pressure, ECG changes (e.g. flattening of T wave, QT interval prolongation, ST-segment depression).
Cardiac disorders: Chest pain, palpitations, tachycardia.
Metabolism and nutrition disorders: Peripheral oedema.
Musculoskeletal and connective tissue disorders: Muscle spasm, musculoskeletal pain.
Nervous system disorders: Headache, dizziness.
Respiratory, thoracic and mediastinal disorders: Upper respiratory tract infection, nasopharyngitis, sinusitis, cough, oropharyngeal pain, rhinorrhoea.
Potentially Fatal: Paradoxical bronchospasm.
Inhalation/Respiratory: C
Monitoring Parameters
Monitor forced expiratory volume in the 1st second (FEV1), forced vital capacity (FVC), other pulmonary function tests; serum K, blood glucose, blood pressure, heart rate. Monitor deterioration of COPD and re-evaluate therapy as needed.
Overdosage
Symptoms: Increased pulse rate, systolic blood pressure, QTc interval; other exaggerated adverse effects (e.g. tachycardia, palpitations, headache, ventricular arrhythmias, hypokalaemia, hyperglycaemia). Management: Supportive and symptomatic treatment. Administer cardioselective β-blockers under physician supervision. Monitor cardiac function.
Drug Interactions
Sympathetic effects may be potentiated with sympathomimetic agents. Enhanced hypokalaemic effect of methylxanthine derivatives, steroids or non-potassium-sparing diuretics (loop or thiazide diuretics). Increased risk of prolonged QTc interval with MAOIs, TCAs, or other agents known to prolong QTc interval. Antagonistic effect with ß-adrenergic blockers. Increased serum concentration with inhibitors of CYP3A4 and P-glycoprotein (e.g. ketoconazole, erythromycin, verapamil, ritonavir).
Action
Description: Indacaterol is a long-acting β2-adrenergic agonist. It acts by stimulating intracellular adenyl cyclase thus increasing the level of cyclic 5’-adenosine monophosphate (AMP) resulting in the relaxation of bronchial smooth muscle. Indacaterol is a long-acting ß2-adrenergic agonist. It acts by stimulating intracellular adenyl cyclase thus increasing the level of cyclic 5’-adenosine monophosphate (AMP) resulting in the relaxation of bronchial smooth muscle.
Onset: 5 minutes.
Duration: 24 hours.
Pharmacokinetics:
Absorption: Bioavailability: 43-45%. Time to peak plasma concentration: Approx 15 minutes.
Distribution: Volume of distribution: 2,557 L (IV). Plasma protein binding: Approx 95%.
Metabolism: Metabolised in the liver by CYP3A4, CYP2D6 and CYP1A1 to hydroxylated indacaterol and by UGT1A1 to phenolic O-glucuronides.
Excretion: Via faeces (>90%; 54% as unchanged drug, 23% as hydroxylated metabolites); urine (<2% as unchanged drug). Elimination half-life: 40-56 hours.
