التداخل بين بوسبيرون وديلتيازيم

This finding is consistent with the in vivo interactions observed between buspirone and the following: Diltiazem and verapamil: In a study of nine healthy volunteers, coadministration of buspirone (10 mg as a single dose) with verapamil (80 mg t.i.d.) or diltiazem (60 mg t.i.d.) increased plasma buspirone concentrations (verapamil increased AUC and C max of buspirone…

Other inhibitors and inducers of CYP3A4: Substances that inhibit CYP3A4, such as ketoconazole or ritonavir, may inhibit buspirone metabolism and increase plasma concentrations of buspirone while substances that induce CYP3A4, such as dexamethasone or certain anticonvulsants (phenytoin, phenobarbital, carbamazepine), may increase the rate of buspirone metabolism.

Consequently, when administered with a potent inhibitor of CYP3A4, a low dose of buspirone used cautiously is recommended.

Adverse events attributable to buspirone may be more likely during concomitant administration with either diltiazem or verapamil.
