Finding a Greater
Vantage Point for
Creating Green Therapies

While sustainability has been the banner under which many topics
have been debated, its focus here is on decreasing the ongoing
negative environmental impacts of drug-delivery combination
products without increasing patient risk. Much of the discussion
herein is focused on inhalers due to the current state of evolving
regulations, but analogous challenges can be found throughout the
combination product ecosystem and, indeed, across virtually every
industry. The drive to create greener products has been ongoing
for quite some time. This journey, however, has been accelerated by
recent concurrent legislative proposals in Europe aimed at reducing
the use of fluorinated gases (F-gases) and eliminating ~10,000 perand
polyfluoroalkyl substances (PFAS). Among the compounds
included are ones popularly used as propellants in pressurized
metered dose inhalers (pMDIs), necessitating a rapid leap ahead in
the search for more environmentally friendly, or green, propellants.
At present, HFC-134a is the predominant propellant, in part because
its large industrial footprint means it is cheap and readily available.
Unfortunately,
it
also has significant
global warming potential
(GWP), a measure of the global warming contribution of one ton of
gas compared to the same amount of CO2
, which has a GWP of 1. As
measured by the United States Environmental Protection Agency
(EPA), HFC-134a has a GWP of 1,430.1
For comparison, the GWP of
HFC-134a is more than 11 times that of one likely replacement, HFC152a.
Given this and the fact that pMDIs alone account for around 3%
of healthcare-related emissions from the National Health Service in
the U.K., it is clear that we can, and indeed must, make adjustments
to lessen the impact of pMDIs on the environment.2
It is, however,
vital that this is not an end point in the conversation but is instead a
waypoint on the path to truly greener therapies. So, while there has
been a reflexive response toward demonizing pMDIs and championing
dry powder inhalers (DPIs), the conversation must take into account a
patient-centric, holistic view of all inhaled therapies for meaningful,
responsible change to happen across the industry.
The Failure of One-Size-Fits-All
Suggestions for lessening the impact of inhaled therapies on the
environment tend to center around two general ideas: 1) change
propellants in pMDIs and 2) switch to a different device, such as a DPI.
While both options should be considered as part of a larger patient78
