Abstract

Частицы аминокислоты, такой как лейцин, могут быть получены из паров аминокислоты, например, с помощью аэрозольной конденсации или с помощью распылительной сушки. Частицы аминокислоты имеют объемную плотность не более чем 0,1 г/см, или имеют усредненный по массам медианный аэродинамический диаметр, не превышающий 10 мкм, или находятся в виде хлопьев, имеющих толщину, не превышающую 100 мкм. Включение частиц аминокислоты в порошок для использования в порошковых ингаляторах, как обнаружено, улучшает вдыхаемую долю активного материала в порошке.Отчет о международном поиске был опубликован 2000.10.12.
