<p>The subject matter relates to an overcap (10) containing a desiccant (30) for use with a metered dose inhaler (12) to adsorb moisture. The overcap advantageously reduces the amount and rate of moisture ingress into the metered dose inhaler. The operation of metered dose inhalers containing agroscopic drug particles is improved by reducing moisture ingress.</p> |
