Human Equivalent Dose

?Human Equivalent Dose #

  • HED = mg/kg / conversion factor (which is human km (standard=37)/animal km)
    • Km = body weight $\div$ body surface area (me: ~1.9; use online calculator) = 39.2.
      • i.e 50mg/kg x (6/39.2 = 0.15333) = 7.65mg/kg

  • More like 6.5ish for me for rat

Freebasing #

  • Conversion constant = HCL salt molecular weight / freebase molecular weight. The former is ~36.5 + the freebase molecule, so something like 1.12-1.14
