A powder inhaler comprises a medicament container, a rotatable metering disc extending into the interior of the medicament container and an air channel through which air is drawn via a mouthpiece. The metering disc has one or more peripherally located dosing grooves extending axially through the metering disc. The dosing grooves are filled with a metered dose of the medicament while being inside the medicament container and are transferred to the air channel wherein the stream of inhaled air discharges the dose of the medicament directly from the dosing groove.
