  • Inhaler apparatus with modified surfaces for enhanced release of dry powders
    Publication number: 20010004892
    Abstract: In one aspect, the present invention provides an inhaler apparatus comprising interior surfaces having contact with a medicament for inhalation, the interior surfaces including an interior surface of a mouthpiece and a substrate with medicament deposited thereon, at least one of such interior surfaces comprising indentations or raised areas therein, the raised areas having valleys therebetween. In certain preferred embodiments, the interior surface is a surface on a substrate having medicament deposited thereon, and in other preferred embodiments, the interior surface is an interior surface of the mouthpiece of the inhaler. In addition to providing surface topology for minimizing the area of contact between the medicament and the surfaces of the inhaler, the surfaces are preferably made of a material having a low surface energy, and more preferably, also having, when uncharged, no substantial van der Waals or electrostatic interaction with the medicament.
