A disposable intranasal brain-targeting drug delivery apparatus comprising an administering apparatus. The administering apparatus comprises a container (1) having a cavity and used for accommodating an agent, a catheter (2) in communication with the container (1) and used for introducing the agent in the container (1) into the nasal cavity, and a spray nozzle (4) arranged at an extremity of the catheter (2). The extremity of the catheter (2) can be extended into the olfactory area above a horizontal position corresponding to the middle nasal concha. The other extremity of the catheter (2) is connected onto the container (1). The administering apparatus also comprises a pressure-sensitive film (3) used for separating the cavity of the container (1) from a lumen of the catheter (2) and rupturing under pressure. The drug delivery apparatus allows highly efficient delivery of the agent to the olfactory area for direct absorption by the brain, thus providing therapeutic effects to the central nervous system.
