Aclidinium does not prolong the QTc interval or have significant effects on cardiac rhythm.
- Mechanism of action
Aclidinium is a long-acting, competitive, and reversible anticholinergic drug that is specific for the acetylcholine muscarinic receptors. It binds to all 5 muscarinic receptor subtypes to a similar affinity. Aclidinium's effects on the airways are mediated through the M3 receptor at the smooth muscle to cause bronchodilation. Prevention of acetylcholine-induced bronchoconstriction effects was dose-dependent and lasted longer than 24 hours.

Bioavailability, healthy subjects = 6%; T max, healthy subjects = 10 minutes; Time to steady state, healthy subjects = 2 days;
- Volume of distribution
Following IV administration, the volume of distribution is 300 L
- Protein binding

- Metabolism
The major route of metabolism of aclidinium bromide is hydrolysis, which occurs both chemically and enzymatically by esterases in the plasma. Aclidinium bromide is rapidly and extensively hydrolyzed to its alcohol and dithienylglycolic acid derivatives, neither of which binds to muscarinic receptors and are pharmacologically inactive.
- Route of elimination
Intravenously administered radiolabelled aclidinium bromide was administered to healthy volunteers and was extensively metabolized with 1% excreted as unchanged aclidinium. Approximately 54% to 65% of the radioactivity was excreted in urine and 20% to 33% of the dose was excreted in feces. The combined results indicated that almost the entire aclidinium bromide dose was eliminated by hydrolysis. After dry powder inhalation, urinary excretion of aclidinium is about 0.09% of the dose.
- Half-life
Plasma half-life = 2.4 minutes (indicating that aclidinium is very rapidly hydrolyzed in plasma into its two inactive metabolites and has a low chance of causing systemic side effects). Effective half-life = 5-8 hours.
- Clearance
Total clearance, IV dose, young healthy subjects = 170 L/h (inter-individual variability of 36%)
