From what I researched none of those medications seem to fit the criteria to help with the SN CTB.
The kinds of medications you will need are others, but remember they are all optional.
Antiemetics like metoclopramide and ondansetrone help prevent vomiting
Painkillers like ibuprofen and paracetamol help with the headache that comes from the drop in blood pressure
Some people use propranolol to deal with tachycardia and make it so their heart doesn't race
Omeprazole or cimetidine can help protect the stomach from the effect of the chemical reactions between stomach acids and SN, which could lead to heartburn
Benzos are medications like diazepam or clonazepam that help you fall asleep faster after the SN ingestion, lessening the conscious time where you would be feeling the symptoms
There are even more medications that could help, but remember to not interrupt your treatment with those and to check any effects that may come from mixing different medicines
I recommend reading one of the megathreads to gain extensive knowledge on the SN method before attempting it
