So, Larotrectinib is this medicine that blocks TRK receptors, like TRKA, TRKB, and TRKC, in tumors that have something called NTRK gene fusions. It’s used to treat cancer that can’t be removed or has spread in both adults and kids. You can get this drug in capsules that are either 25 or 100 mg, and also as a liquid that’s 20 mg in every mL.
The usual dose for grown-ups is taking 100 mg twice a day. These capsules come in bottles with 60 in each. For kids, the dose depends on how much space they take up.
You’re supposed to take the capsules by mouth.
