That info about flouroquinolone is interesting. I've discovered that I was treated years ago using antibiotics that would definitely not be prescribed today. I will keep an eye on the drugs like Pirenzepine.
Generally, this family of drugs should no longer be used as first line treatment. Doctors still often use it as first line for UTI though. It carries a very high risk of damage to tendons and neurological system.
It is also the only antibiotic which is topoisomerase inhibitor, other drugs which are topoisomerase inhibitors are chemo drugs. It means that it blocks the enzymes needed to divide and regrow cells.
