Interventions

  • Drughydroxyurea

    Hydroxyurea (500 mg capsules) was administered in a single dose at a mean of 10/mg/kg/day (range8-12mg/kg/day).

  • DrugL-carnitine and hydroxyurea

    Hydroxyurea (500 mg capsules) was administered in a single dose at a mean of 10/mg/kg/day (range8-12mg/kg/day). L-carnitine (Minoo, Iran, 250 mg tablets) was administered in divided doses (50mg/kg/day).

  • Drughydroxyurea and magnesium chloride

    Hydroxyurea (500 mg capsules) was administered in a single dose at a mean of 10/mg/kg/day (range8-12mg/kg/day). Magnesium chloride powder ( tabib tajhiz nik, Iran) was formulated into suspension; each ml containing 1meq magnesium chloride. It was administered in divided doses at 0.6meq/kg/day.
