Description

An α-anomer, obtained by crystallization at low temperature, can be dehydrated to stable form above 130°C or an unstable (hygroscopic) form at lower temperatures. An example of the applications for α-Lactose monohydrate is in dry powder inhalers. These are devices that deliver medication to the lung in the form of a dry powder generating an aerosol directly from the drug powder or mixture, using an excipient such as lactose monohydrate.
