1. An inhaler, comprising:
- a respiration indicator,a chamber wall forming a chamber,a dispensing device for fluidic connection of the chamber to a nostril, anda discharge nozzle for forming an aerosol,wherein the chamber comprises an intake opening arranged for receiving the aerosol from the discharge nozzle and the dispensing device comprises an outlet from the chamber for the aerosol,wherein the inhaler is at least one of closed and airtight between the intake opening and the outlet,wherein the respiration indicator comprises a wall section extending across and airtight sealing a through passage formed in the chamber wall, wherein the wall section is flexible and configured to indicate a respiratory activity by deformation thereof, the wall section being deflectable into the chamber from a rest position of the wall section during inhalation and being deflectable outward relative to a surrounding portion of the chamber wall during exhalation, andwherein the chamber is formed from a dimensionally stable material apart from said wall section so as to be unresponsive to said respiratory activity except at said wall section.
