liver enzyme will affect blood levels.
- Some drugs increase the activity of CYP3A
and result in reduced levels of DAA and thereby reduce their effectiveness, for
example, corticosteroids (for example,
- Other drugs decrease the activity of CYP3A and result in
elevated levels of the and possibly can lead to toxicity, for example, some of
the anti-fungal drugs (for example, itraconozole [Sporanox]).
medications may need to be changed while taking some of the hepatitis C DAA.
