Extractable Substances Since pressurized inhalers and aerosols are Typically formulated with organic solvents as being the propellant or even the automobile, leaching of extractables through the elastomeric and plastic parts in the formulation can be a possibly serious problem. Thus, the composition and the standard of products Utilized in the manufacture of the valve components (e.g., stem, gaskets, housing, and here so forth.) must be meticulously selected and controlled. Their compatibility with formulation components ought to be perfectly recognized In order to prevent distortion of the valve elements and to attenuate changes during the medication supply, leak fee, and impurity profile from the drug item as time passes.
