  • Pharmaceutically acceptable agents for solubilizing, wetting, emulsifying, or lubricating in metered dose inhaler formulations which use HFC-227 propellant
    Patent number: 5508023
    Abstract: 1,1,1,2,3,3,3-heptafluoropropane (HFC-227) has been identified as a highly polar propellant. Surfactants which have an elevated value (9.6 or greater) for their hydrophilic-lipophilic balance (HLB) can be used as suspending, wetting, and lubricating agents or cosolvents in metered dose inhaler (MDI) formulations pressurized with HFC-227 or propellant blends that contain HFC-227. Particularly preferred surfactants include polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan mono-oleate, polyethylene glycol 300, propoxylated polyethylene glycol, polyoxyethylene 4 lauryl ether, and diethylene glycol monoethyl ether.
