1. A method for treating a pulmonary disease or disorder in a patient, the method comprising:
- providing a metered dose inhaler comprising a canister containing a pharmaceutically acceptable co-suspension, the co-suspension comprising;
a suspension medium comprising a pharmaceutically acceptable propellant free of additional constituents;
a first species of respirable active agent particles comprising a pharmaceutically acceptable salt, ester, or isomer of glycopyrrolate in crystalline form, as a first active agent;
one or more additional species of respirable active agent particles comprising one or more additional active agents selected from the group consisting of a short-acting beta agonist, a long-acting and ultra long-acting β
2 adrenergic receptor agonist (LABA), a corticosteroid, an anti-inflammatory, an anti-tussive, a bronchodilator, and a muscarinic antagonist; and
a plurality of respirable suspending particles, wherein the total mass of the respirable suspending particles exceeds the total mass of the respirable active agent particles, the plurality of suspending particles are formed of a dry particulate phospholipid material that is substantially insoluble in the suspension medium, and the active agent particles associate with the plurality of suspending particles to form a co-suspension; and
administering the co-suspension to the patient by actuating the metered dose inhaler, wherein said administering of the co-suspension comprises delivering a dose of 150 μ
g or less of glycopyrrolate per actuation of the metered dose inhaler and said delivery results in an increase in FEV1 of at least 70 mL in 0.5 hours or less, and the at least 70 mL increase in FEV1 remains for up to 12 hours or more.

Abstract
Compositions, methods and systems are provided for pulmonary or nasal delivery of two or more active agents via a metered dose inhaler. In one embodiment, the compositions include a suspension medium, active agent particles, and suspending particles, in which the active agent particles and suspending particles form a co-suspension within the suspension medium.

16. A method for respiratory delivery of a therapeutically effective amount of at least two active agents to a patient, the method comprising:
-
providing a metered dose inhaler comprising a canister containing a pharmaceutically acceptable co-suspension, the co-suspension comprising; a suspension medium comprising a pharmaceutically acceptable propellant free of additional constituents; a plurality of respirable active agent particles comprising a pharmaceutically acceptable salt, ester, or isomer of glycopyrrolate in crystalline form, as a first active agent; one or more additional species of respirable active agent particles comprising one or more additional active agents selected from the group consisting of a short-acting beta agonist, a long-acting and ultra long-acting β
