The present invention provides an actuator (10) for a nasal inhaler (5). The actuator comprises an elongate body (15) comprising a canister opening (11), a nose piece (30) adapted for nasal delivery of a medicament, and fixing means for fixing the nose piece to the elongate body (15). The nose piece is fixable to the body at an acute angle to the elongate body. A first portion of the nose piece defines an outlet (25) for discharging a medicament from the actuator. The nose piece is adapted and the elongate body is adapted so that when the nose piece is fixed to the elongate body, the nose piece and elongate body cooperate to define a fluid communication pathway from the canister opening to the outlet. The present invention is also directed to an inhaler comprising an actuator as discussed, and a canister.
