Metered medication dose

A medical product comprising a metered dose of a dry powder peptide medicament loaded in a sealed container, made to fit into an adapted dry powder inhaler, wherein

• said peptide medicament comprises at least one micronized peptide powder and optionally at least one biologically acceptable excipient powder in dry powder form acting only as a carrier or diluent for the peptide(s);
• the at least one peptide powder is in a pure form, without any substances included in the dose that are intended to change or enhance one, some or all properties of the peptide;
• the sealed container enclosing the metered dose is a dry, moisture-tight, high barrier seal container adapted for a prolonged dose delivery from the container using the adapted dry powder inhaler;
• the metered dose is arranged to be aerosolized gradually into inspiration air directly from the container, when opened, by the suction effort made by a user of the adapted inhaler, whereby more than 40% by mass of the at least one peptide powder, contained in the metered dose, leaves the inhaler as a fine particle dose;
