The powerful extended effect of antibiotics

The post-antibiotic effect is the time where bacterial growth continues to be inhibited after the antibiotic concentration becomes undetectable. It is influenced by the type of bacteria, the antibiotic, the concentration, the combination of antibiotics, and the exposure time.
This feature is very important because it allows us to design the dosage of antibiotic therapy, for example, antibiotics with a prolonged post-antibiotic effect require less frequent dosing and antibiotics with a short post-antibiotic effect need to be administered more frequently.
