Help Difference between brands of drugs?

[goblinofisiyal11]

So I am trying to order Metoclopramide tablets from an Rx-free online store, but there are two versions of it, a brand one which costs 50% more expensive than the generic one. Is there a reason why there is such a price difference, why there are even two variants in the first place, besides just the design of the tablets, like Gucci and offbrand Gucci? Which should I order?

When patents expire other companies can make/sell generics and offer them at a lower price. That's how pharma works. I don't think it's something to be overly concerned with.
