What is peak and trough in iv medication?

In intravenous (IV) medication, "peak" refers to the time when the drug concentration in the bloodstream is at its highest after administration, indicating its maximum therapeutic effect. Conversely, "trough" is the point just before the next dose, reflecting the lowest concentration of the drug in the bloodstream. Monitoring peak and trough levels helps ensure effective dosing while minimizing toxicity and optimizing therapeutic outcomes. Accurate timing of these measurements is crucial for medications with narrow therapeutic Windows.
