Which of the following best defines the term 'therapeutic window' in clinical pharmacology?

Which pair correctly matches the term to the organ commonly affected by antimicrobial toxicity?

Calculate the therapeutic index (TI) for a drug with a lowest effective dose of 20 mg and a lowest toxic dose of 200 mg. Based on the TI, how would you characterize prescribing safety?

A patient with reduced renal function receives Drug Z with LED = 10 mg and LTD = 30 mg (TI = 3) and Drug W with LED = 10 mg and LTD = 1000 mg (TI = 100). The patient's impaired renal clearance is expected to double systemic exposure to either drug. Which drug poses a greater risk after renal impairment and why?

Pharmacokinetic modeling predicts that co-administration of Drug A with a commonly used inhibitor will increase Drug A plasma levels by 70%. If Drug A has a TI of 2 under normal circumstances, analyze the impact of the interaction and recommend prescriber actions.
