A metered combined dose is disclosed for a combined administration of medicinal dry powders. A metered medicinal dry powder combined dosage comprising at least two medicaments of separate dry powder formulations is prepared and the metered powder is deposited in a dose forming step. The deposits of the at least two medicaments are suitably kept separated from each other, such that the medicaments cannot detrimentally interact after forming of the combined dose. The medicinal combined dose is introduced into an inhaler device for a delivery of the powder dose during the course of a single inhalation.
