ANORO ELLIPTA vs STIOLTO RESPIMAT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ANORO ELLIPTA is a combination of umeclidinium, a long-acting muscarinic antagonist (LAMA), and vilanterol, a long-acting beta2-adrenergic agonist (LABA). Umeclidinium inhibits acetylcholine at M3 receptors in bronchial smooth muscle, causing bronchodilation. Vilanterol stimulates beta2-adrenergic receptors, leading to relaxation of bronchial smooth muscle and increased cyclic AMP.
Dual bronchodilator: tiotropium is a long-acting muscarinic antagonist (LAMA) that inhibits M3 receptors at smooth muscle, causing bronchodilation; olodaterol is a long-acting beta2-adrenergic agonist (LABA) that stimulates beta2 receptors, relaxing airway smooth muscle.
One inhalation (umeclidinium 62.5 mcg / vilanterol 25 mcg) once daily, orally inhaled.
2 inhalations (2.5 mcg tiotropium/2.5 mcg olodaterol per inhalation) once daily via Respimat inhaler.

Umeclidinium: 11 hours (terminal); vilanterol: 2.5 hours (terminal). Steady-state achieved by day 14 once-daily dosing.
Tiotropium: 5-6 days (terminal). Olodaterol: 17-19 hours (terminal). Clinically, once-daily dosing maintains therapeutic levels.
Umeclidinium: 0.7% unchanged in urine, 58% as metabolites in feces; vilanterol: 26% unchanged in urine, 70% as metabolites in feces. Total elimination: renal (30-40% for vilanterol metabolites) and fecal (primary).
Tiotropium: 14% renal unchanged, remainder as non-renally eliminated metabolites (biliary/fecal). Olodaterol: <1% renal unchanged, 84% fecal as metabolites, 16% renal as metabolites.
