Quizplus · Accepted Answer

Peak and trough levels are collected to monitor therapeutic drug levels, which help to determine if a patient is receiving the appropriate dose of medication. Peak levels are measured when the drug is expected to be at its highest concentration in the bloodstream, while trough levels are measured just before the next scheduled dose to ensure that the drug is still present in the bloodstream at an effective level. This is particularly important for drugs with a narrow therapeutic index, meaning that there is a narrow range between a therapeutic dose and a toxic dose.
