Description of intervention(s) / exposure
Treatment: Drugs - bosentan

Experimental: Bosentan 2 mg/Kg b.i.d. - 2 mg/kg bosentan administered twice daily (morning and evening) for a planned duration of 24 weeks


Treatment: Drugs: bosentan
32 mg quadrisected dispersible tablet. The dosage of bosentan (2 mg/Kg) was adjusted according to the patient's body weight at initiation of the study treatment. Dosage readjustment was permitted after 12 weeks of treatment.
