Olodaterol lung targeting nanoparticle and its preparation method

The invention belongs to the field of pharmaceutical preparations and relates to an olodaterol lung targeting nanoparticle. The nanoparticle is specifically composed of olodaterol or its salt, a carrier material, a stabilizer and a lung targeting material. The olodaterol lung targeting nanoparticle can be combined with one or a plurality of pharmaceutically acceptable fillers to produce a nebulizer or a dry powder inhalation. The olodaterol lung targeting nanoparticle has the advantages such as high drug carrying capacity, good stability, and the ability to reduce pharmaceutical toxic or side effect; the olodaterol lung targeting nanoparticle is highly lung targetable, highly bioavailable and higher in clinical application value.
