Pulmatrix | Date: 2016-09-27

The present invention is directed toward respirable dry powders and particles for systemic delivery of pharmaceutically active agents or delivery to the respiratory tract. The dry powders contain one or more monovalent metal cations (such as Na^(+)), are small and dispersible.


The present invention is directed toward respirable dry particles for delivery of divalent metal cation salts and/or monovalent cation salts to the respiratory tract and methods for treating a subject having a respiratory disease and/or infection.

The invention relates to respirable dry particles that contain one or more divalent metal cations, such as magnesium, in an amount of less than 3% by weight, and to dry powders that contain the respirable particles. The dry particles can further contain an active agent, or can be used as carrier particles to deliver an active agent.


The present invention relates to respirable dry powders that contain respirable dry particles that comprise about 20%-37.5% (w/w) leucine, about 58.6-about 75% (w/w) calcium lactate, and about 3.9-about 5% (w/w) sodium chloride, and methods for treating a subject using the respirable dry powders.

The present invention relates to respirable dry powder comprising respirable dry particles that comprise sodium chloride, leucine, and tiotropium bromide, wherein the sodium chloride is about 60% to about 90%, the leucine is about 10% to about 40%, the tiotropium bromide is about 0.01% to about 0.5%, and optionally one or more additional therapeutic agents up to about 20%, wherein all percentages are weight percentages on a dry basis and all the components of the respirable dry particles amount to 100%. The invention also relates to respirable dry powders that contain respirable dry particles that comprise sodium chloride, leucine, and tiotropium bromide, wherein the sodium chloride is 67% to 84%, the leucine is 12% to 28%, the tiotropium bromide is about 0.01% to about 0.5%, and optionally one or more additional therapeutic agents up to about 20%, wherein all percentages are weight percentages on a dry basis and all the components of the respirable dry particles amount to 100%. The invention also relates to respirable dry powders that contain respirable dry particles that comprise about 79.5% to about 80.5% (w/w) sodium chloride, about 19.5% to about 20.5% (w/w) leucine, and about 0.01% to about 0.5% (w/w) tiotropium bromide, and methods for treating a subject using the respirable dry powders.
