Why is the drug Brilinta so expensive?

I've been hearing a lot about the drug Brilinta and how it's quite expensive. Could you please elaborate on why that is? Is it because of the complex process involved in its manufacturing? Or does it contain some rare or expensive ingredients? Additionally, how does the pricing of Brilinta compare to other similar drugs in the market? I'm curious to know if there are any efforts being made to bring down the cost of this medication to make it more accessible to patients.
