  • Child-adapted dose of 12.5 mg per tablet taken twice daily for 60 days
  • Easily dispersible tablet to facilitate oral administration
  • No need for tablet fractionation (except for low-birth weight babies <2.5 kg: half a tablet)
  • Simple and reliable administration that does not require complex preparation and can therefore be administered at home, even during the long duration of treatment (twice daily for 60 days)
