What is the capsule strength for Lanoxin?

Yes, it is for a school assignment. Normally, I wouldn’t do this, but I have been searching for about an hour now online and it’s driving me crazy. I can’t get to a reference book, so I’m hoping someone here will know. I need to know what the adult and pediatric capsule strengths are. If there isn’t one for kids, then that’s okay. All I can find are that they exist. Also, the oral solution for kids, if there is one. Feel free to direct me to any website, too. They might come in handy later. Thanks!
