Which medication among the following would typically require few to no plasma level checks in routine clinical practice?

Explanation:
Dabigatran is a direct oral anticoagulant with predictable effects across most patients, so routine plasma level monitoring isn’t needed. Dosing is guided mainly by renal function, age, and body weight, not by trying to hit a specific blood concentration. In contrast, drugs like theophylline, lithium, and warfarin require regular laboratory monitoring to ensure safety and efficacy because their effects are highly sensitive to blood levels or coagulation status. Theophylline has a narrow therapeutic window, lithium requires trough levels to avoid toxicity, and warfarin anticoagulation is guided by the INR to keep it within a target range. Therefore, among these, dabigatran typically needs few to no routine plasma level checks.
