Incruse Ellipta
Incruse Ellipta
Generic Name
Incruse Ellipta
Mechanism
Incruse Ellipta contains tiotropium bromide, a *long‑acting inhaled anticholinergic bronchodilator*.
• Selective M₃ muscarinic receptor antagonist → blocks acetylcholine‑mediated bronchoconstriction.
• Prolonged action due to slow dissociation from receptors, providing >24 h bronchodilation.
• Minimal β₂‑adrenergic activity → lower risk of tachycardia compared to LABAs.
Pharmacokinetics
- Route: Intratracheal inhalation via Ellipta dry‑powder inhaler.
- Absorption: ~18 % pulmonary, remainder swallowed (systemic exposure ≈ 70 %).
- Distribution: Wide tissue distribution; plasma protein binding ~75 %.
- Metabolism: Primarily hepatic (Cytochrome P450 3A4) → deactivation to inactive metabolites.
- Excretion: Urine (≈ 60 %) and feces (≈ 30 %).
- Half‑life: Pulmonary residence ≈ 8 h; systemic plasma half‑life ≈ 35 h.
- Drug interactions: Minor CYP3A4 inhibition/induction modestly changes exposure; avoid concurrent anticholinergics (e.g., glycopyrrolate) to prevent additive GI effects.
Indications
- Maintenance therapy for Chronic Obstructive Pulmonary Disease (COPD) in adults.
- Preferred once‑daily dosing for *stability and patient adherence*.
- Not an acute rescue inhaler; use short‑acting bronchodilators for exacerbations.
Contraindications
Contraindications
• Hypersensitivity to tiotropium or any excipient.
• Severe narrow‑angle glaucoma (risk of acute elevation).
Warnings
• Urinary retention → precipitate in patients with bladder outlet obstruction.
• Cardiac arrhythmias → may cause bradycardia especially in patients on β blockers.
• Pregnancy/Lactation → Category C; use only if benefit > risk.
• Elderly → increased dry mouth, constipation.
Dosing
- Adults: 18 µg (one capsule) once daily.
- Administration:
1. Tilt inhaler 10‑15° forward.
2. Breathe‑in slowly; do not exhale into device.
3. Seal lips around mouthpiece → inhale as deep as tolerated, hold breath 10 s.
4. No priming required; press the capsule against the air outlet for 5 s.
• Storage: Keep in a cool, dry place; avoid high humidity or temperatures >30 °C.
Adverse Effects
| Class | Examples (Common) | Examples (Serious) |
| Respiratory | Dry mouth, sore throat | Hypersensitivity pneumonitis, bronchospasm |
| GI | Constipation, dysphagia | Severe constipation leading to ileus |
| Cardiac | Mild tachycardia | Bradycardia, heart block, QT prolongation |
| Ocular | Blurred vision, ocular irritation | Acute angle‑closure glaucoma |
| Allergic | Rash, pruritus | Anaphylaxis, anaphylactoid reactions |
Monitoring
- Pulmonary function (spirometry) every 4–6 weeks initially, then annually.
- Cardiovascular: Monitor pulse, BP; perform ECG if arrhythmia suspected.
- Ophthalmology: Screen for glaucoma in high‑risk patients.
- Kidney/ liver: Baseline labs if significant hepatic or renal dysfunction.
- Adverse event surveillance: Report any signs of urinary retention, severe GI, or hypersensitivity.
Clinical Pearls
- Device literacy: Patients often misuse Ellipta by exhaling into the device. Train patients to inhale *without exhaling first* and to hold their breath for at least 10 seconds.
- No rescue step: Emphasize that Incruse is not a rescue inhaler; combine *tiotropium* with short‑acting β₂‑agonists (SABA) or inhaled corticosteroids (ICS) as needed.
- Titration caution: Switching from a multilevel‑dose inhaler (e.g., Bivalve®) to Ellipta can double systemic exposure; adjust dosing accordingly.
- Interaction check: Concomitant use of strong CYP3A4 inhibitors (ketoconazole, ritonavir) can raise plasma tiotropium levels; consider dose reduction or alternative bronchodilators.
- Renal considerations: In patients with CKD stage 4–5, monitor closely for exaggerated anticholinergic effects; dose adjustment not formally required but clinical vigilance is advised.
- Dry mouth mitigation: Counsel patients on adequate hydration, use of sugar‑free lozenges, and routine oral hygiene.
