FIELD: medicine.
SUBSTANCE: method involves introducing particles into patient's respiratory tract from a reservoir containing some mass of the particles having filling density of 0.4 g/cm3. At least 50% by mass of particles containing in the reservoir are delivered to pulmonary system of a patient. At least 75% of particles have small particles fraction which size is smaller than 6.8 mcm. The particles are capable of carrying agents like biologically active agents.
EFFECT: enhanced effectiveness in introducing at least 5 mg large single dose of agent into pulmonary tract.
