What is Spiriva (tiotropium) designated for in terms of dosing frequency?

Spiriva (tiotropium) is designated for once-daily dosing due to its long-acting anticholinergic properties. This medication is used primarily in the management of chronic obstructive pulmonary disease (COPD) and asthma, providing sustained bronchodilation over a 24-hour period. The once-daily dosage allows for improved patient adherence and convenience, as patients only need to remember to take their medication once every day.

The pharmacokinetics of tiotropium supports this dosing schedule, as it has a prolonged duration of action that effectively controls symptoms without the need for multiple daily doses, which can be cumbersome and lead to missed doses. This adherence to a once-daily regimen helps ensure consistent therapeutic effects and better overall management of respiratory conditions.
