Study Arms (3)

Monotherapy

ACTIVE COMPARATOR

Sildenafil will be started at 20mg OD and then increased to 20mg TDS if there is no fall in BP. Total duration is of 6 months

Drug: Sildenafil

Sequential Therapy

ACTIVE COMPARATOR

Bosentan will be started at 62.5mg BD for 4 weeks and then increased to 125mg BD. Sildenafil will be started be added after 3 months. Sildenafil will be started at 20mg OD and then increased to 20mg TDS if there is no fall in BP. Total duration is of 6 months. Bosentan and sildenafil will be in combination in the last 3 months. No fixed dose combination will be used.

Drug: SildenafilDrug: Bosentan

Combination therapy

ACTIVE COMPARATOR

Bosentan will be started at 62.5mg BD for 4 weeks and then increased to 125mg BD. Sildenafil will be started at 20mg OD and then increased to 20mg TDS if there is no fall in BP. Total duration is of 6 months. No fixed dose combination will be used.

Drug: SildenafilDrug: Bosentan
