Brief summary
Absorption of inhaled tiotropium is compared between five Tiotropium Easyhaler product variants and Spiriva capsules inhaled via HandiHaler without charcoal. Absorption of tiotropium is compared between one Easyhaler product variant administered with and without charcoal.
Interventions
Tiotropium Easyhaler 10 µg/dose Product variant D
The charcoal suspension will be administered orally with Tiotropium Easyhaler 10 µg/dose Product variant F

Masking description
Bioanalytical laboratory will be blinded with regard to the sequence of the product administration.
Intervention model description
The study is a 2-part 4-period crossover study where the study subjects participate either in part 1 (20 subjects) or in part 2 (20 subjects). Parts can run in sequence or parallel. All study subjects receive single dose of Tiotropium Easyhaler on 3 periods and Spiriva HandiHaler on 1 period.
