Mixtures of propellants are regularly utilized to obtain desirable stress, shipping, and spray qualities. A very good propellant procedure ought to have the correct vapor strain features consistent with the other aerosol components.
Valves The main functionality in the valve is to control the circulation on the therapeutic agent and propellant from your container. The spray properties with the aerosol are motivated by orifice dimension, variety, and location.

As website a result, the composition and the quality of resources Utilized in the manufacture with the valve parts (e.g., stem, gaskets, housing, etc.) must be very carefully chosen and managed. Their compatibility with formulation factors really should be nicely recognized In order to avoid distortion on the valve factors and to minimize changes in the medication delivery, leak rate, and impurity profile with the drug product eventually.
Whilst syrup can be a pharmaceutical Resolution that wholly dissolves into its solvent, Using the distribution of medication within just the solution remaining even, a suspension is drug mixture whereby the drug particles do not totally dissolve into the solvent.
