Each light green, hard gelatin Spiriva capsule contains 18 mcg tiotropium (equivalent to 22.5 mcg tiotropium bromide monohydrate) blended with lactose monohydrate (which may contain milk proteins) as the carrier. The dry powder formulation within the SPIRIVA capsule is intended for oral inhalation only.
