Aggra 100 contains Sildenafil Citrate Bosentan Monohydrate

Moderate

In a study of healthy male volunteers, taking sildenafil at steady state (80 mg t.i.d.) together with bosentan at steady state (125 mg b.i.d.) resulted in a 63% decrease in sildenafil AUC and a 55% decrease in sildenafil Cmax. Bosentan is an endothelin receptor antagonist and a moderate inducer of CYP3A4, CYP2C9 and possibly of cytochrome P450 2C19.

What do Major, Moderate and Minor mean?

Major

The combination can cause serious harm or stop a medicine from working. Usually avoided, or only used with close medical supervision.

Moderate

The combination may need care: a different dose, taking them at different times, or extra check-ups.

Minor

Little or no effect is expected. Usually nothing needs to change.

Duplicate

Two of your medicines contain the same ingredient, which can add up to a double dose.
