Reporting limit determined each analysis
None Detected ng/mL
Peak plasma levels following a 180 mcg dose via an
inhaler: 1.5 ng/mL at 13 minutes post dose.
Peak plasma levels following inhalation of a cumulative
dose of 1 mg and 4 mg: approximately 5 and 20 ng/mL,
respectively, 5 minutes post dose.
Peak plasma levels following a single 8 mg
oral-sustained release tablet:
13 ng/mL at 5.0 hours post dose.
Average steady-state peak and trough plasma
levels following a 4 mg (normal release tablet) every
6 hours for 5 days: 15 and 9.9 ng/mL, respectively.
Serum/plasma concentrations may vary significantly
depending on dose, formulation, route of
administration, device, lung function, and
user mechanics.
