Abstract
An inhaler (10) for administering medicaments in finely divided form contained in capsules comprises a nebulization chamber (42) and a device (16) for piercing the capsule. That end surface of the nebulization chamber containing the holes (48, 49, 50) for the discharge of air laden with the finely divided medicament is shaped such that the capsule, when resting on it, does not impede air passage through any of the discharge holes. The nebulization chamber, at least in that part thereof closest to said discharge holes, tapers towards that end surface of the chamber comprising the discharge holes.
