EPA Bans CFC-Based Asthma Inhalers

bonch writes "The EPA has banned over-the-counter asthma inhalers as part of an agreement with other nations to avoid using chlorofluorocarbons, a substance once used in aerosol sprays. Alternative albuterol inhalers cost almost three times as much as the $20 epinephrine inhalers sold by online retailers."

Government, EPA...what a bunch of idiots. Here we have an inexpensive asthma product, that helps MILLIONS of people each day, and now thanks to the government, it will costs those people MORE for a different product. One of the scariest things ever said was... "I'm from the federal government, and I'm here to HELP you".

Corporations, what a bunch of idiots. Here we have an ozone depleting product, that will affect BILLIONS of people each day, and now thanks to the government, it will save those people MORE by keeping intact the ozone layer. Once of the scariest things ever said was... "I'm from the corporation, and I'm here to SAVE the planet".

Quantitative? I'll take a shot at it.

Quantitative proof or GTFO.

Well, I'll take a shot at it. Please excuse me if I miss a decimal point somewhere, corrections are welcome.

About 14g of material in a Primatene Mist Inhaler. Non-propellant mass is ascorbic acid, dehydrated alcohol (34%), hydrochloric acid, nitric acid, purified water (actual mass of drug is negligible). Don't know the breakdown, but guesstimating about 4g of CFC-12 and CFC-114 propellant per inhaler, since alcohol is ~1/3 mass, and ascorbic acid is listed before the alcohol (ingredients should be listed in order of descending weight, so at least 1/3 ascorbic acid).

In one of the recent news interviews about this, FDA spokesman estimated 1-2 million Primatene Mist users out there. Let's say 12 vials per year * 2mil users (I don't really know how many vials an asthmatic goes through), and call it 20 million vials. That would be 24,000kg of CFCs per year, or 24 metric tons.

For reference, reported peak production of CFC-12 was reached in 1988, at 421,002 metric tons (1000kg in a metric ton), and 8,938 metric tons in 2004 (last reported year). So total usage is not tiny, but still a small fraction of the overall CFC usage.

Actually, engineers resolved the notion of the user powered pump quite some time ago. It's really cool, you just squeeze or depress the mechanism and out comes the product. For the lazy though they've come up with the ingenious notion of replacing the aerosol with carbon dioxide or nitrous oxide when used in human consumables. Either way there are alternatives to CFCs and most cost no different or even less than CFC propellant. The problem isn't the propellant it's the drug manufacturers that feel like charging more.
