Pressurized pharmaceutical aerosols for inhalation therapy. I. Physical testing methods.

The physical testing methods used for controlling the manufacture of pressurized aerosols for inhalation therapy are described. Results of the tests for uniformity of valve delivery, particle size, and pressure of this new pharmaceutical dosage form are reported. A reliable and reproducible aerosolized dose of medication can be administered for inhalation therapy by means of the metering valve on the pressurized container.
