When Should We Use Modafinil Tablets?

I've been hearing a lot about Modafinil-200mg tablets lately and wanted to gather some information on their usage. Can anyone provide insights on when and how Modafinil should be used? Additionally, I would greatly appreciate it if someone could define "Modafinil-200mg" for me. I've come across this term multiple times, but I'm not entirely sure what it means. Can someone explain it in simpler terms?
