A) Antibiotic peak and trough levels monitor therapeutic blood levels of the prescribed medication. The therapeutic range-that is, the minimum and maximum blood levels at which the drug is effective-is known for a given drug. By measuring blood levels at the predicted peak (1-2 hours after oral administration, 1 hour after intramuscular administration, and 30 minutes after IV administration) and trough, usually a few minutes before the next scheduled dose, it is also possible to determine whether the drug is reaching a toxic or harmful level during therapy, increasing the likelihood of adverse effects.
