Paying off one's brother's debts with zakaat money

Q: If there are 2 siblings, one is fairly well off and the other is struggling financially. The “wealthier” one would like to discharge his zakaah.

The question is, can it be given to the struggling sibling, to settle debts. It would pay the credit card debts off and the card would then be cancelled.

Also, debts from medical bills that arose from the birth of their last child, which is with debt collectors. They pay small amounts, but with the interest so it does not do much and the amounts keep increasing. It would only be used for debt payments and no other purpose. Please advise.
