The invention is a medicament magazine having at least one medicament chamber for use in a powder inhaler, wherein the magazine is formed from two foil strips applied to one another and the at least one medicament chamber is formed between the foil strips as depicted in exemplary FIGS. 1a and 1b. The medicament chambers have an internal structure (3) which comprises in its interior a space for receiving a powdered medicament and stabilizes this inner space against external mechanical influences.
