Interaction checkers warn against use of tamsulosin with imatnib, a cyp3a4 inhibitor. but dasatinib is a cyp3a4 inhibitor. why no warnings about it?

See answer: Good question. Both drugs are tkis and both are cyp3a4 inhibitors which have the potential to reduce the metabolism of tamsulosin and thereby the potential for an increase in tamsulosin-associated adverse side effects: dizziness, lightheadedness, drowsiness, runny/stuffy nose, or ejaculation problems being the most common. It may be that imitinib is a stronger cyp3a4 inhibitor than dasatinib.
