ABSTRACT:
A disposable inhaler (10; 50; 60) for administering medicaments in finely divided form contained in capsules (22) comprises a body (12) enclosing a nebulization chamber (20), the capsule being inserted into the nebulization chamber during assembly of the component parts of the inhaler. The inhaler does not comprise a device for piercing the capsule. This latter is pierced before its insertion into the inhaler. A cup is provided for preventing escape of the finely divided medicament through the capsule holes (42, 44) until the moment in which the inhaler is used.
