Inhalers will now use HydroFluoroAlkane (HFA) propellant following India's signature to the Montreal protocol, which calls for replacing CFCs with environment friendly alternatives. "Research has shown that the HFA solution produce very small particles which penetrate the small airway in the lung better than the older CFC formulation," Singh added.
CFC-free inhalers will not only protect the ozone, but also offer effective relief to the estimated 300 million people suffering from asthma and over 210 million suffering from COPD.
