Here in Brazil, we have something called 'Genéricos.' These are essentially the same medications as the brand-name versions, produced with the same chemical ingredients, but they often cost half the price, sometimes even cheaper than that.
Insanely comical.
in the US, we call these 'generics'
Now look into the places that manufacture these generic versions. Not all factories are equal, and some are not of the best of reputations.
Interestingly, while on-patent medications in the US tend to be significantly more expensive than elsewhere, generics in the US tend to be less expensive than generics available elsewhere.
