Final answer:
Prednisone, a corticosteroid, can cause anterior subcapsular cataracts. Atropine poisoning is treated with a muscarinic agonist, and epinephrine is used to treat anaphylactic shock.
Step-by-step explanation:
The drugs that cause anterior subcapsular cataracts include corticosteroids like Prednisone. Indomethacin, Pilocarpine, and Atropine do not typically cause this type of cataract. In the event of atropine poisoning, a muscarinic agonist would be the antidote, as atropine is an anticholinergic agent, which means it blocks the muscarinic cholinergic receptors. An anaphylactic shock, which is a severe allergic reaction, is counteracted with epinephrine, which is the primary treatment to manage severe allergic reactions.
