Aerosol carriers |
摘要 |
Pharmaceutical excipients useful in dry powder inhalents comprise particles having a rugosity (measured by air permeametry) of less than 1.75. The use of these carriers increases the amount of drug injested by the patient using a dry powder inhaler. The preferred excipients are crystalline sugars such as lactose which may conveniently be prepared by controlled crystallisation from an aqueous medium.
