Eli5 – why do you take antibiotics as a course and not all at once?

Question

I’ve just started an antibiotics course which is 4 times a day for 10 days and that got me wondering if they would be just as effective if I took them all and why not.

I done this by taking double doses so I could drink for my 21th birthday 🤣 found out the amount to od on the antibiotic and stayed under the limit lol
