Our bodies in general are designed to reject harmful substances that we are exposed to on a daily basis. Regarding our lungs and breathing, we have numerous built in systems that block and trap most dust, mold, viruses from entering our bodies, although some get through a majority are rejected. This is mostly based on particle size.
When we manufacture a formula for use inside of a MDI and it is built correctly, we are bypassing ALL of the saftey features mentioned above. This means that everything inside the container of the MDI will be delivered to directly to the systemic blood circulation of the human body. Clearly this could cause potential harm or death to a patient.
For this reason alone, it is advisable for anyone that thinks they want to manufacture MDI’s to consult with someone that is familiar with unforeseen dangers of the manufacturing process.
