Viagra was a by-product/side-effect of a (ineffective) drug for angina and hypertension. I'm not sure how much UK government money was involved in that work, but I'm assuming a lot, as we're generally all for that kind of thing.

Also of relevance, the UK patent on using a chemical that gives you an erection as a cure for impotence was thrown out for being obvious. But the patents on how to mass manufacture it are still in effect.

That's cool, but given the subject matter it is hard to treat it with anything other than absolutely no, you-know-what.
