Obesity significantly impacts the pharmacokinetics (PK) of antifungal drugs like echinocandins, including volume of distribution (Vd) and clearance. However, despite these PK differences, current clinical evidence generally does not support the need for universal dose adjustments in obese patients. Clinicians should consider personalized dosing based on patient characteristics, infection severity, and specific drug properties due to echinocandins' favorable safety profiles.
