BACKGROUND: Gentamicin is an aminoglycoside antimicrobial commonly used in horses at 6.6 mg/kg IV once daily. Therapeutic drug monitoring (TDM) can confirm desired peak concentration is reached for common bacterial isolates, and detect toxicosis associated with high trough values. OBJECTIVES: Determine the relationship between gentamicin dose and plasma concentration in hospitalized horses, and identify a starting dose range to achieve peaks > 32 μg/mL. ANIMALS: Sixty-five horses (2002-2010) receiving once-daily gentamicin with TDM performed (N = 99 sets). METHODS: Retrospective study. Data from hospitalized horses including weight, dose, plasma peak, and trough gentamicin concentration, cre..
