Azelastin ve flutikazon ve İmatinib etkileşimi

If either is abnormal, consider prophylactic use of systemic steroids (1-2 mg/kg) for one to two weeks concomitantly with Gleevec at the initiation of therapy.

In these instances, Gleevec was resumed at a dose lower than that at which the reaction occurred and some patients also received concomitant treatment with corticosteroids or antihistamines.

The condition was reported to be reversible with the administration of systemic steroids, circulatory support measures and temporarily withholding Gleevec.

Use of Cytochrome P450 3A4 Inhibitors Ritonavir and other strong cytochrome P450 3A4 (CYP3A4) inhibitors can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Drug Interactions ( 7.2 ) and Clinical Pharmacology ( 12.3 )] .

Use caution with the coadministration of azelastine hydrochloride and fluticasone propionate nasal spray and other potent CYP3A4 inhibitors, such as ketoconazole [see Drug Interactions ( 7.2 ) and Clinical Pharmacology ( 12.3 )] .

• Other potent CYP3A4 inhibitors, such as ketoconazole: use caution with coadministration.

Cytochrome P450 3A4 Ritonavir (a strong CYP3A4 inhibitor) significantly increased plasma fluticasone propionate exposure following administration of fluticasone propionate aqueous nasal spray, resulting in significantly reduced serum cortisol concentrations [see Clinical Pharmacology ( 12.3 )] .

Caution should be exercised when azelastine hydrochloride and fluticasone propionate nasal spray is coadministered with ketoconazole and other known strong CYP3A4 inhibitors.
