A quick Google search brings this up:
A semicolon is most commonly used to link (in a single sentence) two independent clauses that are closely related in thought.
So that means what is before and what is after the semicolon each needs their own subject and verb.
You can offset the "abc" with commas and that is the same as saying "that is". I think this is called apposition.
He took a new drug, abc, to treat the COVID.
To answer your final question, here are some ways you could use a colon:
He took a new drug: abc.
To treat the coronavirus, he took a new drug: abc.
He took a new drug -- abc -- to treat the coronavirus.
But you really wouldn't say
NOT CORRECT: He took a new drug: abc to treat the coronavirus
However, this probably works:
He took a new drug: abc (to treat the coronavirus).
