A nasal spray device (1) for the delivery of a pharmaceutical formulation to the nasal cavity is disclosed. The device (1) comprises a pressurised aerosol canister (4) with a metering valve (6) having a valve stem (8). The device further comprises an actuator (2) displaceable relative to the canister(4) including a stem block (11) to receive the valve stem and a sump (15) extending below the valve stem receptacle. The stem block further defines a discharge orifice (19) for the pharmaceutical formulation and a transfer channel (13) through which the dose is able to pass from the sump (15) to the discharge orifice (19). The actuator (2) further comprises a nose piece(12) for the aerosol plume. The device is adapted to produce an aerosol plume with a spray force value no greater than 40 mN at a distance of 30 mm from the discharge orifice (12).
