title: Effect of low-dose dopamine on the pharmacokinetics of tobramycin in dogs.
abstract: Low-dose dopamine or a placebo was given to six healthy mongrel dogs, each receiving tobramycin at 2.0 mg/kg on consecutive days in a randomized crossover fashion. Dopamine increased the total and renal clearances and elimination rate constant of tobramycin by 12.5, 20, and 25.9%, respectively, suggesting that low-dose dopamine increases the clearance of tobramycin in dogs primarily through renal mechanisms.
