Xylocaine(without epinephrine)
Class IB antiarrhythmic blocking fast sodium channels preferentially in depolarized/ischemic tissue. Suppresses ventricular ectopy.
DOGS primarily — cats very sensitive to toxicity (lower doses). IV bolus then CRI. CNS toxicity (tremors, seizures) at excessive doses. Do not use with epinephrine formulation.
Each ExoticRx dose rule is graded by the strength of its primary evidence — see the editorial process.
