It’s used to deal with that type of lung cancer, the one where the cells aren’t small, and don’t stick together when cancerous. It’s called NSCLC. It aims its gun at mutations in the EGFR part of the cell.
It locks in on this specific tweak, like a tiny genetic variation called the T790M thingy. So, this thing comes as a tiny, covered pill which you could take twice a day, each pill giving you the medicine. The usual kick is taking twice as much as the 40-miligram ones, so 80 milligrams a day.
No problem popping this drug with or without eating – it works either way. And these come in a box of thirty pills per bottle, just the way your doc told ya. The usual routine, once in the am, that’s the go for this pill.
It’s about keepin’ the kind of cancer, I mean this non small cell kind, kind of controlled. And, for that specific version of the cancer (that genetic tweak of the EGFR and the T790M – you’ve probably got it right)– that’s where you’d wanna use this med.
