Abstract: 1. A pharmaceutical composition deliverable from a metered dose inhaler, the pharmaceutical composition comprising: a propellant of pharmaceutical grade 1,1-Difluoroethane (HFC-152a); a plurality of active agent particles; and a plurality of phospholipid particles comprising perforated microstructures; wherein the active agent particles comprise an active agent selected from a long-acting muscarinic antagonist (LAMA), a long-acting P2-agonist (LABA), a short-acting beta-agonist (SABA), an inhaled corticosteroid (ICS), and a non-corticosteroid anti-inflammatory agent. A metered dose inhaler comprising a canister with an outlet valve including an actuator for dispensing a metered amount of said pharmaceutical composition, wherein the canister contains the pharmaceutical composition. Said composition for use in the treatment of a pulmonary disease or disorder.

Abstract: Compositions, methods, and systems are provided for pulmonary delivery of active agents via a metered dose inhaler. In some embodiments, the compositions comprise an HFO-1234ze (E) suspension medium, active agent particles, and suspending particles. The active agent particles may comprise one, two, three or four active agent(s) selected from a long-acting muscarinic antagonist (LAMA), a long-acting ?2-agonists (LABA), a short-acting beta-agonists (SABA), an inhaled corticosteroid (ICS), and a non-corticosteroid anti-inflammatory agent.
