lb equals 111.72 mcg - 204.82 mcg kg


This ped patient falls in the marked group.

Age Digoxin Dose
(mcg/kg/day)
5 - 10 y 6 – 11


  • Low dose: `(6 mcg)/(x)` = `(1 Kg)/(18.62 Kg) `

    Therefore `x` = 111.72 mcg



  • High dose: `(11 mcg)/(x)` = `(1 Kg)/(18.62 Kg) `

    Therefore `x` = 204.82 mcg

    Hence the dosage range for digoxin is
    111.72 mcg - 204.82 mcg
