Modification In Propellant Helps to Improve Environment
It has taken a bit of tim, but finally the hundreds of thousands of people using propelled inhalers have finally, and reluctantly made the switch from CFC- propelled inhalers to HFA-propelled inhalers.
The change in law legally occurred on the last day of December last year. Fundamentally, the intent for the change in the law was for environmental reasons. The old CFC inhalers used chlorofluorocarbon. Studies have shown that chlorofluorocarbon is one of the major culprits when it comes to depleting the atmosphere’s ozone layer. When a CFC inhaler is used, the person breathes in chlorofluorocargon along with whatever medicine he is taking. And then, when the person exhales, he exhales the CFC also. When the CFC hits the atmosphere, ultraviolet light breaks them down. This is what causes the ozone to be depleted.
The United States is one of the last of the major industrialized nations to implement the change. Countries such as Canada, Europe, and Japan had all previously made the change.
Americans use medicinal drugs every year for symptoms as different as dog allergies, grass pollen allergy, and sulfa drug allergies. Even though the law changed last year to prevent the old inhalers from being produced and sold, no doubt there are still many people who have yet to replace their old inhalers with the newer ones.
According to the FDA, HFA, or hydrofluoroalkane, is much a much friendlier substance to the environment than CFC.
Since the changeover, users of the new HFA are primarily experiencing two differences.The biggest change is that the newer model inhalers have a tendency to become frequently clogged whereas with the original inhalers, this was not a problem. Secondly, from the standpoint of a patient, the taste is somewhat different.
Even though the amount of the propellant is small in each individual inhaler, since millions of people used the inhalers each year, the change is expected to significantly decrease the amount of harm done to the environment.
