Therapeutic drug monitoring is used when a drug’s exposure must be kept within a narrow, carefully balanced range: high enough to be effective, but not so high as to cause toxicity, with patient-to-patient variability making fixed doses unreliable. Aminoglycosides exemplify this. They need peak levels high enough for bactericidal activity, but troughs kept low to minimize nephrotoxicity and ototoxicity. If the levels are too low, the infection may not be treated effectively; if too high, toxicity can occur. Clinicians routinely measure peak and trough levels and adjust dosing accordingly to achieve that balance. The other drugs can be monitored for safety or interactions, but the described pattern of concentration-dependent efficacy with a clear toxicity risk at high levels and failure at low levels aligns best with aminoglycosides.
